Hello, everybody!
I'm trying to open, get, put, close WebSphere MQ queuе through JMS API.
I want to connect to the queue manager, open a specific queue, put in her message, get the message and then close and disconnect. Earlier I connected to the MQ through MQ API.
With the help of colleagues from this forum, I was able to write a program with the help of which I got the opportunity to put messages in the queue and pick them up. This program is very cumbersome. I made it in the OpenEdge 10.1B, using installed the WebSphere MQ client 7.5 and downloaded the manual "MQSeries Application Programming Interface". It was a test and this solution is not used in our product.
Now I'm using version 11.6.3. Having learned that since version 11.5.1 I can interact with WebSphere MQ without using the SonicMQ (I do not have licenses for this product), I became interested and decided to figure it out.
My task of interacting with WebSphere MQ queues is complicated by the fact that I have to access the queue from the server (not from the client, as in the program I wrote earlier). For these purposes, I plan to use purchased and installed on the database server PAS for OE. In any case, this is how I call the web services: the program on the client calls the application server on which the service call programs run.
So, I started to study the documentation "Messaging and ESB". I made the necessary changes in jmsProvider.properties and AdminServerPlugins.properties in In the %DLC%\properties path:
pluginclasspath=C:\Program Files\Progress\OpenEdge_11_6/sonic/MQ8.5/lib/sonic_Client.jar,C:\Program Files\Progress\OpenEdge_11_6/sonic/MQ8.5/lib/mgmt_client.jar,C:\Program Files\Progress\OpenEdge_11_6/java/progress.jar,C:\PROGRA~1\IBM\WEBSPH~1\java\lib\com.ibm.mqjms.jar
classpath=C:\Program Files\Progress\OpenEdge_11_6/sonic/MQ8.5/lib/sonic_Client.jar,C:\Program Files\Progress\OpenEdge_11_6/java/progress.jar,C:\PROGRA~1\IBM\WEBSPH~1\java\lib\com.ibm.mqjms.jar
jvmargs=-DsonicMQExtensions=false -DjmsProvider=WebSphereMQ
After that, I began to doubt: there is a WebSphere client on my workstation. But our users work with software using the Client Networking, hosted on a network resource. Probably I should install the WebSphere client on the network? After all, I must somehow run the SonicMQ adapter? On the server in Progress OpenEdge Management I chose the SonicMQ Adapter Resource. But nothing can be created here. Here I am stuck. Do I need to configure something on the server or just make changes to the properties files? Maybe I missed something (did not install it) during the installation of OpenEdge RDBMS?
Can anyone help me? Thanks.
How can I determine that adapter create connection factory? My SonicMQ1 startet without any visible problems. But I don't like log SonicMQ start error:
Main >(Mar 24, 2017 16:53:48:606) : Reading jmsProvider.properties from location : C:\Program Files\OpenEdge\properties\jmsProvider.propertiesMain >: A public jmsfromABL.AdminObjectFinder class was not found.
Hello, Anand. Explain, please - I have a connection to the WebSphere MQ server on my database server (PASOE is running on this server too). I installed MQ Client 7.5 on my server. In the file C:\Program Files (x86)\IBM\WebSphere MQ\java\bin\JMSAdmin.config I have:
Does this mean that the .binding file and the AdminObjectFinder.jar file should be in the server's directory C:\JNDI-Directory? Because now the AdminObjectFinder.jar file lies on server'd disk D in the folder D:\Depo101\DPRO_31_10\MQ.
It seems to me that I made a mistake in the jar file or in JMS configuration...
Here is java file and archive.
I set the log level to 5.
Hi Fuelfire,
We can find the connection factory information in sonicMQ1.server.log as shown below:

From the log it seems AdminObjectFinder.class file is not available under jmsfromABL package in AdminObjectFinder.jar file.
Follow the below steps to generate AdminObjectFinder.jar file
Step 1: Add the following lines in AdminObjectFinder.java
env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory"); env.put(Context.PROVIDER_URL, "file://D:/Depo101/DPRO_31_10//MQ"); env.put(Context.SECURITY_PRINCIPAL, "swiftmq"); env.put(Context.SECURITY_CREDENTIALS, "swiftmq");
Step 2: compile the java file using following command. javac -cp jms.jar:.: -d . AdminObjectFinder.java
Step 3: Now, generate the jar file with below command. jav -cvf AdminObjectFinder.jar jmsfromABL
Step 4: Place the generated jar file in classpath and pluginsclasspath in AdminServerPlugins.properties file.Step 5: Restart the AdminServer and sonicMQ1 broker.
Please find the attached sample AdminObjectFinder.java.
Hope this helps!!
I can not download the file - page not found. From your answer I see that INITIAL_CONTEXT_FACTORY is changed: from "com.sun.jndi.fscontext.RefFSContextFactory" to "org.jnp.interfaces.NamingContextFactory". And in PROVIDER_URL you use double slash after "file:" and before "MQ". I'll do it now. I'll keep you posted. Thank you for your help.
Anand, there are errors on step 2: package javax.jms does not exist.
I used javac in %DLC%\jdk\bin. I run javac on my server.
Last time I generated a class like this:
javac D:\depo101\dpro_31_10\MQ\AdminObjectFinder.java
Probably it's wrong..
Provide the fully qualified path for jms.jar file instead of absolute path. jms.jar file is available under <MQ_client_installation>/java/lib/jms.jar.
javac -cp <MQ_client_installation>/java/lib/jms.jar -d . AdminObjectFinder.java.
:-( I attached inappropriate screen. I have the same error with the full path:
I used the following command:
proenv>javac -cp C:\progra~2\IBM\WebSph~1\java\lib\jms.jar:.: -d . D:\Depo101\DPRO_31_10\MQ\AdminObjectFinder.java
In windows OS, we need to use semi-colon(;) when we are providing multiple jar file names in classpath. It should work if we replace semi-colon(;) with colon(:).
It worked! I create AdminObjectFinder.jar.
When I restart AdminService (and restart SonicMQ1 too) I see this error in sonicmq1.server.log whatever:

1. Anand, could you explain, please, why we should use
env.put(Context.PROVIDER_URL, "file://D:/Depo101/DPRO_31_10//MQ");
env.put(Context.PROVIDER_URL, "file://D://Depo101//DPRO_31_10//MQ");
It is suspicious that does not always use a double slash in the path to the directory (PROVIDER_URL).
I see that the documentation'example uses one slash:
env.put(Context.PROVIDER_URL, "file:/C:/JNDI");
2. I do not like the way to TAB in the bindings file:
Is it wrong path or it's Ok?
I tried to connect WebSphere MQ from the server and from workstation. The difference between this tests - description of recieving error.
When I run program on the server I receive in the sonicmq.server.log:
Caused by: com.ibm.mq.jmqi.JmqiException: CC=2;RC=2495;AMQ8568: The native JNI library 'mqjbnd64' was not found. For a client installation this is expected. [3=mqjbnd64]
When I run program on the workstation I receive:
Caused by: com.ibm.mq.jmqi.JmqiException: CC=2;RC=2495;AMQ8568: The native JNI library 'mqjbnd' was not found. For a client installation this is expected. [3=mqjbnd]
There is WebSphere MQ Client 7.5 in both cases.
Could anyone tell me where I can downloaded mqjbnd64/mqjbnd library? Thanks.
Please find the attached samples.zip file that contains the following files:
1) AdminObjectFinder.java
2) .bindings
From the sonicMQ1.server.log seems that did not created the connection factory. Use the attached files from your reference.
Hi, Anand. I have to make changes to the files. I wrote in AdminObjectFinder.java:
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.fscontext.RefFSContextFactory");
env.put(Context.PROVIDER_URL, "file:D:\\Depo101\\DPRO_31_10\\MQ"); //works for remote client
env.put(Context.SECURITY_PRINCIPAL, "swiftmq");
env.put(Context.SECURITY_CREDENTIALS, "swiftmq");
What should I change in a binding? Server name, port and path to tab? How correctly to specify a CCDT path in this file directly for Windows of environment? I found this description on the website of IBM:
Your .bindings file uses the paths for the Unix environment. In my case this is Windows.
Accordingly, I must replace the path:
Is it correct?
Our bindings files are different. There are lines like "RemoteCF/RefAddr/" In my generated file. Your file contains lines like "RemoteCF/RefAddr" and lines like "RemoteQueueCF/RefAddr" and lines like "RemoteTopicCF".
I got the binding file on my workstation via jmsAdmin.bat. Perhaps it should be generated on the server?
In any case, I need to understand how to specify the path to the tab-file in .bindings.
In the .bindings file we need to provide the location of CCDT path. Below is example to specify CCDT file path in windows:
In my .bindings file I have three different connect factories that is the reason you are able to see multiple connection factories names like RemoteCF, RemoteTopicCF and RemoteQueueCF. I think in your case you might be having only on connection factory.
I must use your tab file? I still left my AMQCLCHL.TAB.
I copy modified AdminObjectFinder.java in D:\Depo101\DPRO_31_10\MQ on the server.
Note how I specified the path to the directory:
env.put(Context.PROVIDER_URL, "file:D:\\Depo101\\DPRO_31_10\\MQ"); //works for remote client
This directory (d:\depo101\DPRO_31_10\MQ) contains my AMQCLCHL.TAB and .bindings. Then I compiled java and packed it in jar (i use %dlc%\jdk\bin on the server):
javac -cp C:\progra~2\IBM\WebSph~1\java\lib\jms.jar;.; -d . D:\Depo101\DPRO_31_10\MQ\AdminObjectFinder.java
jar -cvf d:\depo101\DPRO_31_10\MQ\AdminObjectFinder.jar C:\Progra~1\OpenEdge\jdk\bin\jmsfromABL
Here is the files:
Then I stoped AdminService on server and after a few minutes I started it. My sonicMQ1 adapter is configured to autostart:
Then I check the sonicMQ1.server.log:
Main >======================================================================Main >(Mar 28, 2017 14:19:14:599) D:\OpenEdge\WRK\sonicMQ1.server.log opened.Main >(Mar 28, 2017 14:19:14:599) : Starts Adapter server logging.Main >(Mar 28, 2017 14:19:14:599) : LoggingLevel set to = 5Main >(Mar 28, 2017 14:19:14:599) : The system property: sonicMQExtensions is set to falseMain >(Mar 28, 2017 14:19:14:599) : The classpath is set to C:\Program Files\OpenEdge\java\progress.jar;C:\PROGRA~2\IBM\WEBSPH~1\java\lib\com.ibm.mqjms.jar;D:\Depo101\DPRO_31_10\MQ\AdminObjectFinder.jarMain >(Mar 28, 2017 14:19:14:635) : Reading jmsProvider.properties from location : C:\Program Files\OpenEdge\properties\jmsProvider.propertiesMain >: A public jmsfromABL.AdminObjectFinder class was not found.
Nothing changed!
Do you see a mistake in my actions?
I'll try to use your binding file now. I'm afraid to make a mistake when editing it. Anyway, I'll try. I'll keep you informed.
Anand, please check my program. May be my program is not good? And the reason is not in the configuration.

(Shutterstock) (Newser) – After waking to a 4:30am robocall announcing a snow delay, a Maryland dad was fuming—so he decided to make a robocall of his own. The father of five found an online robocalling company and recorded a message to be sent at 4:30am yesterday to school officials, the Washington Post reports. The message was 29 seconds long. "This is a Prince George's County School District parent, calling to thank you for the robocall yesterday at 4:30 in the morning. I decided to return the favor," Aaron Titus's message said. It also noted that he already knew about the delay before going to bed. Eight of 19 recipients picked up their phones. "I definitely appreciate his creativity," said a school board member. District phone calls won't be coming so early from now on. (Read more robocall stories.)

Last week, the finishing touches were put on the Biogarden greenhouse installation in Yoncalla, Oregon. The result is a dynamic growing system with control panel for automated liquid fertilizer management, a series of 40′ grow systems for deep water culture and 20 Biogarden grow systems for aggregate beds and for making organic liquid fertilizer. The 4, 1100 gallon storage tanks are underground. Two are plumbed to support deep water ebb and flow cycles for the 40′ beds. The other two store concentrated liquid nutrients, also made in the greenhouse with an 'NPK Brewery' Biogarden and water from the well that was drilled last year.
Building an NPK Brewery to make liquid fertilizer
Here I'm setting up an 'NPK Brewery', as we call it, for creating organic liquid fertilizer. This 20′ module at the greenhouse farm Bioponica developed and installed for a client. The Biogarden Brewery has two tanks and produces a total of 600 gallons of liquid fertilizer from biomass. Nitrogen PPM approaches 2500 in 7-10 days. This diyh processed liquid fertilizer can be used on the soil or in hydroponic drip lines. It's sustainable – economically viable, available abundantly, and good for the community.
An high yield of produce anticipated in year one
The 3000 square foot greenhouse contains 1150 square feet of grow beds, proving a 35% space utilization. Space use is important in greenhouse growing as it reflects dollars per square foot of infrastructure. When beds are stacked vertically more space may be occupied. When there is plenty of working area and a greenhouse flows smoothly, growers can effectively harvest and maintain beds with minimum of effort. These features make up the framework for an efficient growing operation.
The first-of-its-kind NPK Brewery will continuously make liquid fertilizer from dry biomass provided by Bioponica.
The future of farming is bright when young farmers are able to utilize innovations in agriculture technology such as those developed at Bioponica. Without soil to manage there will be less labor. With recirculation of water there are less resource demands on a modest supply of well water. By making fertilized water on-site, from inexpensive biomass blends, there is an independence and self reliance that the grower may anticipate for years to come. These features are important when outdoor growers are facing excessive rains, droughts and compromised soil conditions.
Automated control panel
This control panel looks simple but it manages a rather complicated array of functions. The panel supports four 1100 gallon underground storage tanks. One contains concentrated liquid nutrients made by the NPK Brewery plus there's a tank storing well water. These tanks are used to blend a combination of water and fertilizer for tanks three and four which support the 40′ deep water sets of beds. Between the tanks and the total of 12 Biogarden beds, all water, fertilizer and blends are moved automatically from table to table and tank to tank.
Delivering water and nutrients
While nutrients are produced inside the greenhouse with the NPK Brewery, they are stored in one of four underground tanks. As seen in this image both water and nutrients are delivered to tanks that are then balanced to support the series of deep water 40′ grow beds. Whenever more nutrients are needed, the control panel is turned on to deliver from concentrated fertilizer tank. When water is needed the panel delivers water to the mix.
Creating fertility for these beds
Within 3 days of filling the tanks and troughs of the Biofarm grow beds, organic plants are germinated and growing. Within 40 days, there will be enough lettuce in this greenhouse to feed a small army. Plant fertility is entirely supported by organic liquid nutrients derived from inexpensive biomass, produced through a relatively simple process of aeration and biofiltration. Instead of purchasing fertilizers this site is sustainably making liquid fertilizer and effectively maintaining healthy plant growth through efficient soilless bioponics techniques.
A series of 40' Deep water raft Biogarden systems for growing lettuces, microgreens, wheatgrass and basil.
This is a dual level double wide deep water system that extends 40′. With stacked vertical grow beds, lower level plants are protected from excess sunlight, making these beds ideal for lettuces and germinating all varieties of plants and microgreens. The upper beds are for direct sun loving plants. Growers may also use these deep water trough systems for raising crustaceans such as crawfish and shrimp or functional farm foods such as duckweed and algae to feed chickens and other farm animals. Raise all varieties of fish fry and other aquatic organisms.
20' Biogarden aggregate filled grow beds
Aggregate beds are great for heavy feeding plants that require longer grow cycles and more stability for anchoring roots. These porous rock and biochar filled beds are a containment reservoir for abundant nutrients and rhizobacteria that colonize the beds along with earthworms, nematodes and protozoans. Behaving identical to soil beds, the beds contain all the nutrients, hormones and growth factors without typical soil born diseases and weed seeds.
40' Biogarden deep water culture grow beds
This is a series of 40′ Biogarden grow beds that have fixed rafts that accommodate a rise and falling water level to create root level aeration. The nutrient enriched water ebbs and flows from 1100 gallon underground tanks. The gravity flow with control panel functionality reduces pumping and simplifies the process. Solutions are blended by pumping nutrients from one underground tank plus well water from another into the tanks connected to the 40′ beds. This efficiency minimizes effort involved to top off beds with nutrients and water and minimizes labor associated with other deep water beds that are maximized for space utilization and organic plant production.
The Biofarm greenhouse is upgraded and optimized to provide a controlled atmosphere environment
It is important to utilize efficient appliances and greenhouse construction in order to minimize cost of overhead due to heating and cooling. Evaporative coolers are an excellent way to manage the hot summer temperatures. This greenhouse will also soon be getting a shade cloth to minimize cooling and fan costs. A propane heater, insulated thermal space with the greenhouse cover and underground water tanks provide additional temperature regulation.

We've lived together for 2 months now. In those two months a lot of shit has happened. It's possible that I might be over my desire to "get it all over with now". Wait, that's a desire? No, that's how my life is.
After the longest morning of my life, Dean's biopsy came back just fine. The minute the surgeon left me in the waiting room, I burst into tears. I think it was out of sheer relief that something good finally happened and that we wouldn't have to fight yet another battle. Or that I wasn't facing the possibility of losing the greatest thing to ever happen to me. I admit it, when the word "lymphoma" was uttered, my first thought was "you can't do this to me. I finally found this amazing man and you're taking him away from me? Please don't do this!" and then I got over it and realized that no matter what I'd deal with it. It was the realization that I didn't have to face anything like that right this minute, that I could finally be happy with someone and share a life with. That's why I cried in the waiting room. Then I called our moms, reported the good news, and breathed.
Not long after that my dad was out of rehab and moved into a group men's home. We've had a few sharp conversations and there was one that shredded me to the bone. I was ready to write him off forever, but then he and my mom talked a lot and after some more time in AA and another group he likes, my dad started to come around. I haven't entirely given up on the idea of having a father some time in my life.
We got the sperm test results in the middle of all of that too and after waiting two more weeks for my doctor to review them I discovered that I am COMPLETELY fucking fed up with gynecologists in general. Also realized that insurance sucks. Oh and his results were not optimal. My doc wouldn't even give us clomid without another test for Dean and I didn't feel like waiting any more for an answer. She gave us the green light to go to a fertility clinic and that was it. The end of all further conversation with yet another doctor that I felt completely disconnected from.
Dejected I went from hyper "let's make the appointment NOW" to a break down (shocking!) to "fuck this. We don't need the stress. Let's just wait." The plan now? Well I have this super important wedding of my best friend in Toronto in August that is costing a small fortune for us. Actually it's not so bad now because Steph is amazing and is letting me bypass the hotel costs and letting me stay at her place the entire week I'm there. It was like an elephant AND a boulder came flying off my chest. We also have a vacation in September thats almost 100% paid for. And my truck is paid off in August as well. We decided that due to the financial stress of it all and fertility clinics not being known for low costs, we'd wait to even make an appointment at the clinic until September. Another boulder removed. Stress is not good for baby making anyway.
However, since I have always been a multiple blog person, I decided to start a blog a few months ago about the whole trying to get knocked up thing, but I'm taking it a bit more lighthearted there than here. If you're interested, leave a comment with your email address so I can send you the link.
Somewhere in this mix Dean also had a sleep study and the results of that were terrifying. It's amazing he's alive. Suffice to say insurance covered a CPAP machine and now my beloved sleeps with a bizarre mask on his face at night. I made fun of him incessantly until he finally started laughing about it too. At least now he's sleeping through the night and getting his energy back. Slowly.
After all of that, we had to figure out this living together thing. It required making food budgets and sharing all money then distributing said shared money and then figuring out schedules and paying each others bills and saving for things we didn't want to save for and FUCK! We went from zero to married in 2 months flat! The kinks have been worked out, the fights have been had, the sex life has taken a hit, but all in all everything is working out. We don't resent each other for any of it. It's all OUR money even though I make the lion's share and pay all the household items. When big decisions need to be made we actually TALK to each other. We make plans together about the future, where money is going, and how things are spent. See? It's like we're married.
As if all that were not enough, i finally went to see a doctor for a physical and holy shit, she listened to me. It turns out this lack of energy can be attributed to a lack of vitamin D so she ran blood work on that and low and behold, my levels were dangerously low. Then a few other results came back that were NOT good. My blood sugar spiked so now I'm pre-diabetic, my triglycerides went up (but my overall cholesterol score was the exact same number as it was the last 2 years), and then there was the vitamin D thing. Basically I'm falling apart. So I joined a gym. My coworker and her husband are "training" me and so far so good. I had already been changing the way Dean and I eat so that part was easy, but the working out no less than 3 times a week? Holy shit that's hard. If I didn't have my workout buddies, this would be near impossible. Saturday I go in for my free training session where they make up a workout based on me and my needs. So that will be interesting.
And then there's work… well thats just a ball of stress right now. I still love my coworkers and still love my job, it's just really stressful right now. That's all there is to say about that.
So between work, working out, doctor visits, results, and figuring out how to live together it's been a hell of a journey. Now let's see how long it takes me to post again.

Drug Detox: Medical Suboxone Detox program' color='custom-color-heading
Don't let fear of withdrawal symptoms keep you out there using opiates for one more day. Our detox protocol is absolutely painless and easy. You will receive the right amount of medication in a luxury setting with very comfortable surroundings. Smoking is allowed and we always have cigs on hand if you run out. Your first step in recovery from heroin addiction starts here. Our medical drug detox staff is available for you 24 hours and our therapist and case manager are here for you to discuss any concerns. We accept most insurance plans or self pay clients. Couples are accepted and we help you find the right rehab for drug addiction when you discharge from detox care. You can watch movies on Netflix or play video games. Our gourmet kitchen is always open. Ping pong and other games are enjoyed by some patients or you can join in any therapy groups. We offer full time massage therapist and chiropractor.
Safe Withdrawal from Alcohol or Drug Abuse
As the first step in drug and alcohol addiction treatment, detox is also the most intensive in terms of care and treatment. Here at Milestones, our detox center is staffed by seasoned professional medical and psychological specialists, whose primary concern is keeping you comfortable and helping you function through the initial withdrawal from drugs or alcohol.
Focusing on the three main issues of withdrawal, your detox program will address withdrawal symptoms, which can vary from moderate to severe, depending on how heavily and for how long you have been using drugs or alcohol. We will help you to fight the cravings which might otherwise weaken your resolve. We will also help your body to recover from any vitamin deficiencies or other health issues caused by your heroin addiction.
We achieve complete detoxification by addressing the above points with a combination of medication, counseling and coaching. The process will ensure you successfully and safely negotiate the first critical period of your drug or alcohol addiction recovery.
Why Attend our Suboxone Detox Center?
If you decide to try and beat your addiction alone, the obstacles you will face are considerable. More to the point though, you may actually be risking your health by going "cold turkey" without medical support. The withdrawal symptoms alone can soon curtail your resolve, since they may include any of the following:
- Headaches, nausea and vomiting
- Confusion, agitation and hallucinations
- Fever and delirium
- Blackouts or convulsions
In the worst cases, cold turkey can result in seizures or even coma. Therefore it's strongly recommended that you get medical help for your alcohol or drug withdrawal.
Modern medicines can not only prevent you suffering from the worst effects of withdrawal symptoms, but can also make you feel generally comfortable, decreasing the likelihood that you will turn back to drugs or alcohol as a way to relieve acute sickness and pain. Meanwhile, daily medical monitoring will ensure that the right medicines are administered and that any immediate health risks are identified and addressed.
When you arrive you will see the nurse for a intake interview. Medical history, allergies, and drug history are covered. It is important to be honest about your using and relapse. Next you will be given heroin detox medication to relieve symptoms and pain from withdrawal. If you want to go to bed that's cool. You can eat all the snacks you want, drink gatorade, play video games, or watch movies on Netflix.
We offer group therapy and educational groups during the day and counselors are available to talk to throughout the night if you need them. The nurse is on duty 24 hours a day. Smoking is allowed in the proper area outside.
Start Your Recovery Today—the Safe Way
We can keep you safe and well while you withdraw from alcohol or drug abuse. Moreover, our detox program goes beyond initial medical care. Our team will help you prepare for the next stages of your recovery, taking steps to reduce the risk of relapse, which can easily upset your plans to be free of alcohol or drugs. Why not get started right away, by contacting the Center at (561)408-0623
Advice for heroin addict needing inpatient rehab after discharge from detox center.
Our case manager will assist you in the next phase of recovery after you discharge. You may need inpatient or residential rehab for treatment of heroin addiction or other drug of choice. There are a variety of factors to consider when deciding on substance abuse facilities available. Sometimes there are mental health issues to be considered, so a dual diagnosis facility should be looked at. You may be ready for outpatient or halfway house depending on the detox discharge assessment. Our case management team is very knowledgeable on all the latest modalities being used in the addiction field. If you are married we will assist you in finding family therapy or marriage counseling. We also provide a recovery coach to clients who wish to take advantage of this service which can be covered by insurance in most cases. President Obama has mentioned "medically assisted heroin addiction treatment" which includes long term suboxone maintenance after discharge from the detox center. There are opposing views on this program from AA and NA especially. They do not approve of longer term suboxone use or years of maintenance.

County to save money after amending bond
Washington County will save nearly $102,000 after amending a $5.3 million water quality bond.
The modification reduces the interest rate on the bond from 4.89 percent to 3.4 percent, resulting in savings of $101,936 over the remaining six-year life of the loan, according to information provided by the county.
County endorses plan for museum
The Washington County Commissioners on Tuesday endorsed a concept plan for a transportation museum at the Washington County Agricultural Education Center, south of Hagerstown on Sharpsburg Pike (Md. 65).
Sen. Donald Munson, R-Washington, has offered to propose legislation in the upcoming Maryland General Assembly session that would provide a $100,000 state matching grant to build and equip the museum, according to information provided by the county.

Labour, the Liberal Democrats and the Conservatives have all now issued their manifestos. Here's our analysis of their commitments on early childhood education.
The Tory manifesto is the briefest on the topic of early childhood education, with little more than a commitment to follow through on the 30 hours and then "assess what more is needed". They surprisingly have nothing to say on the PVI sector, or on the still vexed area of funding, and focus only on the maintained sector, with capital funding for school nursery expansion, a presumption that new primaries will include a nursery and a commitment to allowing maintained nursery schools to become academies, either independently or as part of a MAT (something that can only work if a viable funding solution is found -about which nothing is said). There is no mention of why the emphasis is on schools eg whether they wish to raise quality through an increase in teacher-led provision There is no mention of workforce, suggesting they have nothing to ad to their workforce strategy.
Labour have a more extensive set of commitments, including to extend the amount of fully funded provision, and to introduce subsidies for additional hours, as well ass moving from the current mixed model to supply-side funding, as well as a commitment to further capital funding. While rationalisation of the current funding system might well be wise, the commitments to extend the amount of fully funded childcare shows a failure to learn from previous experience that the rush to expand places tends to be at the expense of the quality which makes a difference to children's outcomes Labour commit to improve qualifications and pay in the workforce, but do not explain how they will do so affordably at the same time as increasing capacity in the system. They are the only party to commit to scrapping baseline assessment in Reception, and to halting closures of Sure Start children's centres.
The Lib Dems, like Labour, are committed to a gradual proces of extending funded childcare from the end of parental leave until school starting age, starting with extending the 2-year-old provision to all children. They are the only party to commit to increasing funding for disadvantaged children, by tripling EYPP to £1000 per child, which is a welcome recognition of the importance of the early years in combating the impacts of economic disadvantage. The Lib Dems also set a challenging target to have all early years provision let by an early years teacher by 2022.
Members may also be interested in further comments on the manifestos, including from Early Education Vice President Naomi Eisenstadt and trustee Sandra Mathers via the Education Media Centre.

Key excerpts from the manifestos
Conservative manifesto:
A Conservative government will strengthen the teaching of literacy and numeracy in the early years so that all pupils – regardless of background – get the best possible start in life. (p51)
High-quality childcare for working families, supported by thousands of new nursery places a year (p62)
Children and Families
Britain should be the best country in the world for children. We want to reduce levels of child poverty, and have high ambitions for the quality of childcare, children's health and support for vulnerable children for whom the state acts as a parent.
High-quality childcare
We know high-quality childcare is important not just to working parents but even more so to a child's development and happiness. That is why a Conservative government will introduce, this year, thirty hours of free childcare for three and four-year-olds for working parents who find it difficult to manage the costs of childcare. We will go further. The next Conservative government will assess what more is needed, including looking at the best ways that childcare is provided elsewhere in Europe and the world. As a sign of our commitment, we will immediately institute a capital fund to help primary schools develop nurseries where they currently do not have the facilities to provide one. We will introduce a presumption that all new primary schools should include a nursery. And we will continue to support maintained nurseries and allow them to take on academy freedoms, supporting them to grow independently or as part of a multi-academy trust. (p72)
Labour manifesto
Early Years
Currently, there is a gap between the end of maternity leave and the beginning of full-time schooling. This gap can make it difficult for parents, particularly women, to return to work, unless they have access to informal childcare support. There is also extensive evidence that early years education has a major impact on child development, and that time in a formal education setting for young children can improve performance at GCSE and beyond.
Labour would seek to roll out educational provision for early years children as part of a National Education Service that is truly cradle-to-grave.
Labour introduced free childcare hours for parents, which were fully funded and resourced.
Under the Conservatives, the free hours entitlement is chronically under-funded, with provision patchy and hard to navigate. Many providers now simply refuse to participate in the scheme. The result is that many parents aren't even getting the hours they're entitled to.
Labour would:
- Overhaul the existing childcare system in which subsidies are given directly to parents who often struggle to use them, and transition to a system of high-quality childcare places in mixed environments with direct government subsidy.
- Maintain current commitments on free hours and make significant capital investment during our first two years of government, to ensure that the places exist to meet demand.
- Phase in subsidised provision on top of free-hour entitlements, to ensure that everyone has access to affordable childcare, no matter their working pattern.
- Transition to a qualified, graduate-led workforce, by increasing staff wages and enhancing training opportunities. This will benefit staff, who are among our worst-paid workers, and improve child development.
- Extend the 30 free hours to all twoyear-olds, and move towards making some childcare available for oneyear-olds and extending maternity pay to 12 months.
Sure Start, and the support it gives to vulnerable and hard-to-reach parents, was one of the great achievements of the previous Labour government, but under the Conservatives 1,200 Sure Start centres have been lost. Labour will halt the closures and increase the amount of money available for Sure Start. (p35-6)
We will abandon plans to reintroduce baseline assessments and launch a commission to look into curriculum and assessment (p38)
Lib Dem Manifesto:
Our priorities in the next parliament will be: […]
- Investing in high-quality early years education, tripling the Early Years Pupil Premium to £1,000. (p25)
3.2 Quality really counts in early years Investing in high-quality early years education has a huge impact on children's attainment as they enter school. Our most vulnerable children have the most to gain from excellent early years settings, with partnerships with parents a key component. We will:
- Increase our Early Years Pupil Premium to £1,000 per pupil per year.
- Raise the quality of early years provision and aim for every formal early years setting to employ at least one person who holds an early years teacher qualification by 2022. (p26)
We will therefore commit to […]
- Protect the education budget in real terms per pupil from early years to age 19. (p37)
Establish a new online Family University, supported by leading organisations such as the BBC and Open University, to provide every family with advice and guidance for learning and parenting at home, as well as inspiring trips out and local opportunities (p30)
Support families and communities
[…]That's why we will increase the availability of childcare to help parents who want to work and why we will ensure that the benefits system is fair – focusing on helping people and not just saving money. […] Our priorities in the next parliament will be:
- Extending free childcare to all two-year-olds and to the children of working families from the end of paid parental leave, and encouraging new fathers to take time off with an additional month's paid paternity leave… (p57)
6.1 Help with childcare costs
Parents often want to take time out from paid work to care for young children but in many families both parents want, or have, to work. The costs of childcare can be prohibitive and opportunities for flexible working are scarce. In government, we were proud to introduce Shared Parental Leave and increases in free childcare but there are still gaps in the system. We will:
- Expand Shared Parental Leave with an additional 'use it or lose it' month to encourage fathers to take time off with young children. We would make Paternity and Shared Parental Leave a 'day one' right.
- Encourage employers to provide more flexible working, making this a 'day one' right, so that there is a presumption that work is flexible unless there is a clear business reason it cannot be.
- Provide 15 hours a week of free childcare to the parents of all two-year-olds in England. We will then prioritise 15 hours' free childcare for all working parents in England with children aged between nine months and two years.
- Commit to an ambitious long-term goal of 30 hours' free childcare a week for all parents in England with children aged from two to four years, and all working parents from the end of paid parental leave to two years. This will not only help parents afford to work, but will also help all children start school confident, happy and ready to learn.
- Ensure that this provision is fully funded at sustainable levels, provides flexibility for parents who work unsocial hours and enables parents to use free hours during school holidays. (p58)

2 Database Systems User Application Application User Database Management System (DBMS) Database Data Data Data Data Data Data Page 2
3 Multimedia Database Management System Main task of a Database Management System (DBMS) is to abstract from the details of: Storage access Storage management Location of the MDBMS: Embedded between the application domain and the device domain Integration into the system: Through operating system Communication components Multimedia System Application MDBMS Device System Application MDBMS Operating system Communication components Page 3
4 Multimedia Database Management System Persistence of data: Data outlive processing programs and technologies, e.g. companies have to keep data in databases for several decades Consistent view of data: Synchronization protocols provide a consistent view of data in a multi-user system Security of data: Transaction concepts ensure security and integrity protection in case of system failure. Recovery of lost data. Query and retrieval of data: Query languages such as SQL (Structured Query Language) enable formulating database queries Each entry has its state information that can be retrieved correctly Page 4
5 Characteristics of MDBMS Corresponding storage media Multimedia data must be stored and managed according to the specific characteristics of the available storage media Descriptive search methods Query of multimedia data should base on a descriptive and content-oriented search, e.g. Picture of a woman with a red scarf Device-independent interface Hide details of device control, but offer information on specific characteristics of available storage media (read-only, write-once, write-many) Format-independent interface DBMS must hide internal storage format and offer conversions to formats requested by the applications (GIF, TIFF, JPEG,...) This allows changing to new storage technologies without any impact on multimedia applications Page 5
6 Characteristics of MDBMS View-specific and simultaneous data access Allows consistent, multiple and simultaneous data access through different queries of several applications (e.g. shared editing) Management of large amounts of data DBMS must be capable of handling and managing large amounts of data. Need of appropriate referencing mechanisms. Relational consistency of data management Relations among data of one or different media must stay consistent corresponding to their specification. MMDBMS manages the following relations: Attribute Relation: supports different presentation (audio, video, image) of one object Component Relation: includes all parts belonging to one data object Substitution Relation: defines different kinds of presentation of the same information, e.g. equation as tables, graphs, animation Synchronization Relation: describes temporal relations between data units, e.g. lip synchronization of audio and video Page 6
7 Characteristics of MDBMS Real-time data transfer DBMS must perform read and write operations of continuous data in real-time The data transfer of continuous data has a higher priority than other database management actions Primitives of multimedia operating systems should be used to support the realtime transfer of continuous data Long transactions The transfer of large amounts of data will take a long time and must be done in a reliable fashion Page 7
8 Characteristics of MDBMS Relation between the operating system and MDBMS: The operating system provides the management interface for MDBMS to all local devices The MDBMS provides an abstraction of the stored data and their equivalent devices, as is the case in DBMS without multimedia The communication system provides for MDBMS abstractions for communication with entities at remote computers Operating system and communication system can unify all the different abstractions and offer them Page 8
9 Data Structure Lehrstuhl für Informatik 4 Data can be stored in databases as Unstructured (unformatted): data are presented in a unit where content cannot be retrieved by accessing any structural detail Example: Mr. Penguin is a student in the seventh term. Structured form (formatted): data are stored in variables, field or attributes with corresponding values Example: o.student.surname = mustername o.student.name = hermann o.student.age = 41 Page 9
10 Data Types Lehrstuhl für Informatik 4 Multimedia data can be stored in databases as raw, registering and descriptive data types: Raw Data: represent the unformatted information content, e.g. letters, pixel, values Registering data: necessary for correct interpretation and identification of the data; usually concealed in the header. For example: format-description (GIF, TIFF, JPEG, ASCII, EBCDIC,...), compressed/uncompressed data, etc. Descriptive data: information about content and structure of the multimedia data to make use easier and faster, e.g. semantic search Page 10
11 Data Types - Examples Text Characters represent raw data Registering data describe the coding (e.g., ASCII) Descriptive data may include information for layout and logical structuring of the text, or keywords Image Pixels represent raw data Registering data include the height and width of the picture Descriptive data are individual lines, surfaces and subjects Page 11
12 Data Types - Examples Video sequence Pixel matrices represent the raw data Registering data provides, in addition to other information, the number of images per second Descriptive data provide a scene description, e.g. Jan s birthday party Audio sequence The digital sample values created by a simple PCM coding represent the raw data Registering data represent the properties of the audio coding Descriptive data represent the content of the audio Page 12
13 Operations on Data An MDBMS must offer, for all data types, corresponding operations for: archival and retrieval The media related operations will be handled as part or extension of query languages, e.g. SQL Different classes of operations are needed: input output modification deletion comparison evaluation Page 13
14 Operations on Data Input (insert / record) operation: Data will be written to the database The raw and registering data are always needed, descriptive data can be attached later Output (play) operation: Read the raw data from the database according to the registering data Modification: Changing of raw, registering and descriptive data Modification can also be understood as a data conversion from one format to another Deletion operation: Remove an entry from the database The consistency of the data must be preserved Page 14
15 Operations on Data Comparison: Many queries to the MDBMS consist of a search and retrieval of the stored data Queries are based on comparison information Individual patterns in the particular medium are compared with the stored raw data not successful enough Pattern matching, search in descriptive data, etc. Evaluation: Generation of the corresponding descriptive data from the raw and registering data Page 15
16 Integration in a Database Model Design of multimedia database systems base on two different kinds of DBMS: ERDBMS (Extensible Relational Database Management System): Definition of additional, application-dependent data types as domains for attributes Definition of new functions to control behavior of and access to the data Embedding new types and functions into existing RDMBS OODBMS (Object-Oriented Database Management System): Different media are represented by classes, whose instance variables include the data as internal state Class hierarchy allows object relations, offers well information navigation and flexible presentation possibilities Page 16
17 Relational Database Model Simplest possibility to implement a multimedia database is to use the relational database model The attributes of different media in relational databases are defined Attributes can specify text audio video Advantage compatibility with existent database applications Page 17
18 Relational Database Model - Example A relation student is given: Student ( Admission_Number Name Picture Exercise_Device_1 Exercise_Device_2 ) Integer, String, Image, Video, Video A relation s attributes can be specified through different media types: image, exercise, video Other entries are athletics, swimming and analysis Athletics ( Admission_Number Qualification The_High_Jump The_Mile_Run ) Swimming( Admission_Number Crawl ) Analysis ( Qualification Error_Pattern Comment ) Integer, Integer, Video, Video Integer, Video Integer, String, Audio Page 18
19 Relational Database Model Type 1 Relational Model Value of a certain attribute can be fixed over the particular set of the corresponding attribute types, e.g. the frame rate of the video can be fixed In the example, the videos from the exercise devices 1 and 2 will play at the fixed rate defined by the type 1 specification Type 2 Relational Model A variable number of entries can be defined through the type 2 relational model In the example, the individual disciplines of each admitted student are identified through their admission numbers Type 3 Relational Model Additionally, an entry can simultaneously belong to several relations In the example, a video entry of a student can be assigned to the relation athletics as well as to the relation analysis Page 19
20 Object-oriented Database Model In object-oriented databases... classes with objects are defined objects can be put in relations via a class hierarchy a semantic specialization of classes and objects can follow sports institute Example Main class: sports institute Subclass: athletics, swimming Objects: students Advantage: These system offer good information navigation and flexible presentation possibility Disadvantage Query operations are incompletely supported athletics students swimming Page 20
21 Conclusions Lehrstuhl für Informatik 4 Media can be stored in many ways, only a few were talked about:: Optical Storage Compact Disc (CD) for multimedia data like images Digital Versatile Disc (DVD) for videos as main medium Important: new error protection mechanisms like Reed-Solomon code Hard disk / file systems Different requirements to between normal data and multimedia data Suitable data structuring needed New strategies for disk scheduling needed Databases Can base on relational or object-oriented models Structure and behavior of data has to be stored New language primitives are needed Needed here: more work on transaction management and content-based retrieval of data Page 21
