Hi all
Here is the situation. I have primary db in town A and standby in town b. Standby runs in managed recovery mode. Database version is 10GR2.
couple a days ago sysadmin restarted the server where stdby db was running, without properly shutting down the standby database and closing redo log apply service first. Now after mounting the database i am getting this error:
ORA-00600: internal error code, arguments: [3020], [2], [137], [8388745], [], [], [], []
ORA-10567: Redo is inconsistent with data block (file# 2, block# 137)
ORA-10564: tablespace UNDOTBS1
ORA-01110: data file 2: 'O:\ORADATA\ABCD\UNDOTBS01.DBF'
ORA-10560: block type 'KTU SMU HEADER BLOCK'
Restarting the redo log apply service didn't help to clear the error. What is my best course of action to get rid of the error and make logs properly apply to standby
regards
skodman

Subject: ORA-600 [3020] "Stuck Recovery"
Doc ID: Note:30866.1 Type: REFERENCE
Last Revision Date: 09-JAN-2006 Status: PUBLISHED
Note: For additional ORA-600 related information please read Note 146580.1
PURPOSE:
This article discusses the internal error "ORA-600 [3020]", what
it means and possible actions. The information here is only applicable
to the versions listed and is provided only for guidance.
ERROR:
ORA-600 [3020] [a] [b] [c] [d] [e]
VERSIONS:
version 6.0 to 10.1
DESCRIPTION:
This is called a 'STUCK RECOVERY'.
There is an inconsistency between the information stored in the redo
and the information stored in a database block being recovered.
ARGUMENTS:
For Oracle 9.2 and earlier:
Arg [a] Block DBA
Arg [b] Redo Thread
Arg [c] Redo RBA Seq
Arg [d] Redo RBA Block No
Arg [e] Redo RBA Offset.
For Oracle 10.1
Arg [a] Absolute file number of the datafile.
Arg [b] Block number
Arg [c] Block DBA
FUNCTIONALITY:
kernel cache recovery parallel
IMPACT:
INSTANCE FAILURE during recovery.
SUGGESTIONS:
There have been cases of receiving this error when RECOVER has
been issued, but either some datafiles were not restored to disk,
or the restoration has not finished.
Therefore, ensure that the entire backup has been restored and that
the restore has finished PRIOR to issuing a RECOVER database command.
If problems continue, consider restoring from a backup and doing a
point-in-time recovery to a time PRIOR to the one implied by
the ORA-600[3020] error.
Example:
SQL> recover database until time 'YYYY-MON-DD:HH:MI:SS';
This error can also be caused by a lost update.
During normal operations, block updates/writes are being performed to
a number of files including database datafiles, redo log files,
archived redo log files etc.
This error can be reported if any of these updates are lost for some
reason.
Therefore, thoroughly check your operating system and disk hardware.
In the case of a lost update, restore an old copy of the datafile and
attempt to recover and roll forward again.
If the Known Issues section below does not help in terms of identifying
a solution, please submit the trace files and alert.log to Oracle
Support Services for further analysis.
