The IASCKPT data set is a DIV data set backed by a VSAM Linear Data Set. The file contains the message queues for messages being sent to the agent and received from the agent before that message is passed to CA WA CA 7 Edition. The file also contains selected information about the agents (for example, statistics) and user ID/password information. The file is also referred to as the communication queue.
To allocate this file, use the sample JCL supplied in the CA IAS supplied library CIASJCL(IASCKPT).
Consider the allocated size of the data set. Because it is a DIV file, the entire file contents are loaded into storage for processing. We recommend that you start with no more than ten cylinders primary and, optionally, two cylinders secondary. The required size depends on several items:
For example, 25 agents, 250 average jobs, and 50 passwords, the approximate space requirement is about 8 percent of 2 cylinders (1,474,560 bytes).
Back up this file on a periodic basis. Although the backup can occur while the CA 7 Online system is active, the CA 7 Online system must be brought down when the data set is reloaded, moved, or both. In the CA IAS CIASJCL library are several members to perform backup and reload of the file:
Most of the data in the IASCKPT file is dynamic; the exception is the user ID/password information. Over time, you can add a number of these user ID/passwords to the IASCKPT file. If the agent queue information becomes corrupted, you can restore the password information without the agent queues by using a file backup and the IASCKPRP JCL.
Note: For more information about the IASAGENT, IASCRYPT, or IASCKPT files, see the CA Integrated Agent Services Implementation Guide.
