Description:

After migration to CA Common Services r12 and z/OS 1.12 we get messages like:

   IEC988I CAIENFX7,CAIENFX7,ENFPARMS-1,C50E,7XRZ01,
   RZX7.CAI.PRODUCTS.PPOPTION DATA SET NOT UNALLOCATED DURING CLOSE RC 04

However, these message only show up if parameter files are concatenated. Are these messages a result of a change within CA Common Services or within z/OS 1.12?

Solution:

The IEC988I messages come from FREE=CLOSE of the ENFPARM DD statement, because since z/OS 1.12 all concatenated datasets get this message when the dataset is CLOSED and FREE=CLOSE is specified in the close parameters.

The IEC988I message can be safely ignored as it is informational only.
