Configuration Best Practices › PRTLIB Repositories Management

PRTLIB Repositories Management

When configuring CA SymDump Batch, you must set your default PRTLIB. The PRTLIB repository is the VSAM data set that maintains your abend reports. You can have one repository for multiple z/OS systems or one per system. However, care must be taken to determine if your installation requires the use of more than one PRTLIB.

Business Value:

Well managed repositories let your application programmers easily locate, access, and share abend reports for their applications. You can use multiple repositories per system with the use of multiple default tables or by using a user exit. As a result, you get better performance from your CA testing tools, optimal use of your DASD space, and the best possible productivity for your application programmers.

Additional Considerations:

When CA SymDump Batch is configured, the default PRTLIB data set is defined with the PRTLIB option of CAOUDFRX. However, not all installations may prefer writing all abend reports to one repository. Specific installations may want a few groups to write to a specific repository. To provide this flexibility, you can override the PRTLIB value in several ways.

• Use the existing user exit, CAOCUPRT to return the PRTLIB to use based on JOBNAME, STEPNAME, abending program name, and USERID.
• Define the PRTLIB by specifying a PRTLIB value in your CAIOPTS DD within the job step JCL.
• Allocate the CAIOPTS DD dynamically for each user by following the naming convention userid.CAIOPTS.
