GLYPH<SM590000> Db2 utilities that are used for index maintenance, such as LOAD, REORG, and REBUILD.  Indexes allow quick access to table rows, but over time, the databases become less  efficient and must be maintained as data in large databases is manipulated. GLYPH<SM590000> z/OS Communications Server uses the zIIP for eligible Internet Protocol Security (IPSec)  network encryption workloads. This configuration requires z/OS V1R10 or later. Portions  of IPSec processing take advantage of the zIIPs, specifically end-to-end encryption with  IPSec. The IPSec function moves a portion of the processing from the general-purpose  processors to the zIIPs. In addition, to run the encryption processing, the zIIP also handles  the cryptographic validation of message integrity and IPSec header processing. GLYPH<SM590000> z/OS Global Mirror, formerly known as Extended Remote Copy (XRC), also uses the zIIP.  Most z/OS Data Facility Storage Management Subsystem (DFSMS) system data mover  (SDM) processing that is associated with z/OS Global Mirror can run on the zIIP. This  configuration requires z/OS V1R10 or later releases. GLYPH<SM590000> The first IBM user of z/OS XML system services is Db2 V9. For Db2 V9 before the z/OS  XML System Services enhancement, z/OS XML System Services non-validating parsing  was partially directed to zIIPs when used as part of a distributed Db2 request through  DRDA. This enhancement benefits Db2 V9 by making all z/OS XML System Services  non-validating parsing eligible to zIIPs. This configuration is possible when processing is  used as part of any workload that is running in enclave SRB mode. GLYPH<SM590000> z/OS Communications Server also allows the HiperSockets Multiple Write operation for  outbound large messages (originating from z/OS) to be run by a zIIP. Application  workloads that are based on XML, HTTP, SOAP, and Java, and traditional file transfer can  benefit. GLYPH<SM590000> For business intelligence, IBM Scalable Architecture for Financial Reporting provides a  high-volume, high-performance reporting solution by running many diverse queries in  z/OS batch. It can also be eligible for zIIP. The zIIP runs portions of eligible database workloads, which helps to free computer capacity  and lower software costs. Not all Db2 workloads are eligible for zIIP processing. Db2 UDB for  z/OS V8 and later gives z/OS the information to direct portions of the work to the zIIP. The  result is that in every user situation, different variables determine how much work is redirected  to the zIIP.  On a z15 server, the following workloads can also benefit from zIIPs: For more information about zIIP and eligible workloads, see the IBM zIIP website. One CP must be installed with or before any zIIP is installed. In zNext, the zIIP-to-CP ratio is  2:1, which means that up to 126 zIIPs on feature Max190 can be characterized. The  allowable number of zIIPs for each model is listed in Table 3-3. zIIPs are orderable by using FC 1947. Up to two zIIPs can be ordered for each CP or marked  CP configured in the system. If the installed CPC drawer has no remaining unassigned PUs,  the assignment of the next zIIP might require the installation of another CPC drawer.
