RMAN-08137: WARNING: archived log not deleted, needed for standby or upstream capture process

In one of our database where GoldenGate setup is done, RMAN process was not able to delete the archive logs. The error message that coming up while running RMAN archive log deletion command was:

archived log file name=+ARCH/DB/archivelog/2017_11_01/thread_1_seq_240409.574.961612255 thread=1 sequence=240409
RMAN-08137: WARNING: archived log not deleted, needed for standby or upstream capture process


Above error means that the GoldenGate process is holding up the archives and not allowing the archives to delete since it believe that those archives are required. Note that we are using GoldenGate integrated capture which means that GoldenGate is integrated with Database/RMAN and RMAN will take into account the GoldenGate process before deleting archives.

We next verified the long running transactions in database if any such is stopping the archivelog deletion.
Below query was used to find any long running transaction which may be holding up the GoldenGate process and archivelog deletion.

select vs.inst_id, vt.xidusn, vt.xidslot, vt.xidsqn, vs.sid,vs.serial#,vs.client_identifier, vs.username, 
 vs.program, vs.machine, vt.used_ublk,
 vt.start_time, TO_CHAR(SYSDATE, 'MM-DD-YYYY HH24:MI:SS') Current_Time
 from gv$transaction vt, gv$session vs where vt.addr = vs.taddr order by vt.start_time ;

There were few long running transactions but all were read-only OBI related.

We next verified the GoldenGate Extracts status

We found that above all three extracts had recent Redo logs date so the three extracts were not stopping the archive logs deletion.

Next we verified all three registered GoldenGate capture process

Usually killing any long running transaction after verification helps in clearing up the archive log but this time issue was with a new test extract as shown below.

select capture_name, CAPTURED_SCN,APPLIED_SCN,OLDEST_SCN from dba_capture;

As shown OGG$CAP_INITLD which is EXTRACT INITLD was at old SCN. This new EXTRACT was added to fix an issue with the out-of-sync tables with EDWP. This extract was later on not used but was stuck at that SCN and this was hindering archive log deletion.

Unregistered this non-required extract:

GGSCI > dblogin  USERIDALIAS aogg
Successfully logged into database.

GGSCI > unregister extract INITLD database
2017-11-03 10:49:37  INFO    OGG-01750  Successfully unregistered EXTRACT INITLD from database.


Ran the archive purge job again and this time it successfully purged the archive logs.
