The  RACRPORT EXEC  does not contain the logic that is in the  RACDSMON  exec, where  RACDSMON might determine what type of tdisk space was defined on your system. With the  RACRPORT  EXEC , you must specify the tdisk disk type. The  query tdisk  command (see Example 5-58) gives you information about system-defined  tdisk space. However, it does not provide the characteristics of the disk device. You must  query the devices to obtain the disk type. With this information, you can select the correct type of tdisk to create as the sort disk. The  EXEC then provides you with the information about the SMF disk that is being used for the  generation of this report (see Example 5-59). The requirement is that the sort disk must be  the same size or larger than the source disk. As a preferred practice, make the sort disk the  same size as the source disk.  After you define the size of the source disk, the tdisk is created as address 5FF (this address  must be available). It then uses the definitions that you created in the  RACFRW CONTROL  file and  generates a console file in your VMRDR. You can use the  peek  command to view this file or  receive it to disk. If you print it, it should be printed on a printer that supports logical record  lengths of 132 characters. Because of variations from one installation to another, and all different types of policies that  are used by the companies, it is not possible to identify all of the ways an auditor might use  the RACFRW.
