Hello Richard,
thanks for the hint, the incremental dbbackups have run daily,
adding up to
13 incrementals in the series in question. Could backup_chg_pct
equal or
greater than 100 lead to a full dbbackup being requested? I did´nt
find
anything in the docs...
Hello, Markus -
ANR2361E is one of those messages with a terse Explanation which
fails to help the customer understand what might be at issue.
I would not expect the backup_chg_pct value to precipitate a full
backup; and, as you found, there is no knowledge base to say that it
might. I would expect a Full to be required only if the previous
Full in the current Backup Series went away (as via DELete
VOLHistory) - and, possibly, if one of the Incrementals in the midst
of the series mysteriously disappeared. A Full, alone, should not go
away if using DRM: the whole series should expire, per the timestamp
of the last volume in it, in conjunction with the
DRMDBBackupexpiredays value. If using File type volumes, you have
other exposures.
Whatever the cause, I would caution against employing any appreciable
number of Incrementals between Fulls: "tape is tape", and it takes
just one defect to ruin the ability to recover your database to
currency.
