Hi Rick,
Not sure what could be going on, but a few thoughts:
- You indicate you are running 7.1.6. Is that 7.1.6.0? If yes, there are a
couple of APARs you should be aware of that are related to instrumentation:
IT16364 and IT16403. These are fixed in 7.1.6.3 and later. If either of
those are in play, the closest might be IT16364 (see the APAR description
for details, https://www.ibm.com/support/docview.wss?uid=swg1IT16364).
Beyond that:
- Are these files that you always expect will get backed up? Or is it truly
possible that might not have changed since the last backup? I mention this
in case you want to consider using the SELECTIVE command rather than
INCREMENTAL. That is, if the file is always expected to be backed up, then
you can eliminate the overhead of incremental processing by just using
SELECTIVE.
- Regarding the file spec /xxxx/arch_yyyy.log: is the file directly
under /xxxx? Or are you expecting dsmc to traverse the directory structure
to look for the file? Are there files with the same name that will get
backed up? If this is just a one-file-at-at-time backup, consider
specifying the fully qualified path, to avoid time spent traversing the
file system. Then you an also get rid of the -SUBDIR=YES option.
My thinking is, if you are doing backups of specifically targeted files,
then dsmc could be doing a lot of unnecessary processing by using
INCREMENTAL and -SUBDIR=YES.
If the problem persists and none of the above helps, I suggest collecting a
SERVICE trace that captures the problem, and opening a PMR with IBM
support.
Regards,
Andy
