RE: Longer backup after an IPL

[Mike Cunningham <mcunning@xxxxxxx>]

If would not change how long the backup takes but it would explain the anomaly and we can stop looking for another cause that might be of our own creation.

Would knowing why change anything?  Probably not.  What we do is a DSPOBJD
to an output file to perform "first touch" so the backup completes in the
same window.

Longer backup after an IPL






Does anyone know the system internals well enough to know what might cause
the first system backup after an IPL to run longer?  We IPL weekly (lets
not get into a discussion of this being necessary) and we have a backup
script that runs one series of saves Monday night through Friday night and
a compressed one on Sat and Sun (we are not open weekends). Sunday we IPL.
Every monday night the backup takes 4 hours, tuesday-friday it's 3 1/2
hours. I know some database stats get cleared on an IPL. Could this be
causing longer backups?
