Logretention preventing rman from deleting old archives
Last updated on JULY 30, 2016
Applies to:Oracle GoldenGate - Version 188.8.131.52.8 and later
Information in this document applies to any platform.
RMAN cannot delete old archived logs whike extracts are working with the database and registered for logretention.
SQL>select * from dba_capture
returns that first_scn/ start_scn is growing for one of the extracts, but not for another one.
This correlates strongly to time from which RMAN stopped deleting archived logs.
In addition, dba_capture shows for one of the extracts start_scn=first_scn=11/29 and this holds archived logs from being deleted.
Another extract works as expected, and first_scn=start_scn = very recent time.
