Determine whether you have a damaged VSAM data set.
Some incorrect
output failures involve a damaged VSAM data set. To determine whether
you have a damaged data set, use the IDCAMS EXAMINE command as described
in the topic on functional command format in z/OS DFSMS Access Method Services Commands and
the topic on checking a VSAM key-sequenced data set cluster for structural
errors in z/OS DFSMS Using Data Sets. The EXAMINE command provides details
about the nature of data set damage.
If these service aids
indicate that the data set is not damaged, inform the IBM Support Center if you call for assistance. If
they indicate that the data set is damaged, keep a copy of the output
for possible use by the IBM Support
Center. Be prepared to describe the type of data set damage. You should
attempt to recover the data set and rerun the failing job to determine
whether the problem is resolved.
The system can indicate a
damaged data set by one of the following:
- Messages (discussed in Message section)
- ABEND0C4 (discussed in ABEND section)
- Wait/Loop (discussed in Wait/Loop section)
- RPL feedback word: nnX'08'nnX'9C' or nnX'08'nnX'20'
