Hello Tom,
Thank you for your hints.
- I tried various cache sizes, exagerating in both directions, without much effect. It is currently 32GB, memory usage for the whole system usually stabilizes around 26GB.
- scl.conf sort of grew on us organically, as issues developed and were fixed by support. I cannot review it, as I was told that scl.conf parameters are a great mystery that should not be revealed to the uninitiated:
nbu.scl.collector.serviceSyncPeriodInSecs=120
nbu.scl.collector.imageSyncPeriodInSecs=600
nbu.scl.collector.jobSyncPeriodInSecs=180
nbu.scl.collector.serviceThresholdEventCount=20
nbu.scl.collector.imageThresholdEventCount=1000
nbu.scl.collector.nonDoneJobSyncPeriodInSecs=3600
nbu.scl.agent.imageAgentTimeout=360000000000
- Purge config is:
Backup Job, Alert, Audit Trail: 420 days
SLP images: 90 day
the rest: 31 days
Time is 8:00, it is enabled, expired image purge disabled.
- Data is purged, as can be seen in reporting, but it is interesting that we completely lack a "purge-status.log" file. It appeared once upon a time, but seems to have gone underground again. Initially, we only experienced performance problems during the hour or two that it took for purge to complete, but this is no longer so.
- Performance warnings arise, due to fragmentation and I defrag the database and the disk. This helps a little bit.
- Thanks for the A/V advice, I will try that.
Regards,
Milan
