Limitations

Processing with GDG protection files requires special attention because the GDG number is updated only at the end of the JOB. CA‑PFF protection files are typically merge files created by using the previous protection file as input and adding new members. Trying to use the same GDG protection file twice causes JCL errors.

You can avoid this problem if you:

• Use unique GDG indexes for each Library Code so that protection file processing never refers to the same protection file for different Library Codes.
• Consider splitting the batch processing cycle to separate the various Library Codes. Each job can then create its own unique generation of the GDG.

Note: If you have not created any previous CA‑PFF PROTECTION GDG data sets, you receive a JCL error the first time you run the data set in your job. This error occurs because the generation (0) data set does not exist. To avoid the JCL error, create the generation (0) data set before using this JCL.
