Defining the User Profile Dataspace

To use the platform server user profiles, you must define the platform server user profile VSAM dataspace.

Procedure

Edit the SYSIN parameters of the DEFPROF JCL to specify the volume and file name according to your installation requirements.
IDCAMS is invoked to create a linear VSAM file.
Submit the JCL and verify that the linear VSAM file is successfully created.

Note: In some cases, it might be necessary to re-create the profile queue (ProfileQ) file. The JCL is written to be able to be rerun. Therefore, after deleting the existing ProfileQ file, you will get an error code result when the job runs for the first time. If this is the only error code that you receive, you can ignore it.

The amount of disk space that the platform server actually uses is determined by the PROFILEQ parameter on the platform server startup JCL. For more information, see EXEC PARM Fields Used by Platform Server.

A user profile entry (128 bytes) is created for each user profile definition. Each user profile entry remains in the user profile dataspace until that entry is specifically deleted. The size of the linear VSAM file depends on the user profile definitions anticipated in the user profile dataspace at any given instance.
Note: This file contains sensitive security information and must be defined to the security subsystem so that only the platform server address space can read the file. This file is not updated by any platform server batch jobs. Users who delete, define or back up the data set must also be given access to the data set.
