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.
