Copying and dumping a PDSE data set using the VALIDATE PDSE option (OW48074)

DFSMSdss sometimes invokes the file and attribute management services (FAMS) to process PDSE data sets in logical data set COPY and DUMP operations. By default, DFSMSdss does not enable the FAMS validation option because validation can slow the processing time. However, a DFSMSdss logical COPY or logical DUMP operation with the FAMS validation disabled might not detect a potentially broken PDSE. It might copy or dump the invalid PDSE with return code zero—without processing all members.

To change the VALIDATE PDSE option, set the flag at offset X'4B' in ADRPATCH. Use the following settings:

X'00': DFSMSdss functions without using the FAMS VALIDATE PDSE option.
Any setting other than X'00': DFSMSdss functions using the FAMS VALIDATE PDSE option.

Note: This patch byte is only valid for logical COPY and DUMP operations when you do not specify the CONCURRENT keyword.

You can use the SET PATCH command to set the patch byte at offset X'4B' to X'FF', or you can modify the sample JCL (see Sample JCL) as shown below:
