We are accessing a rollback segment header to see if a transaction has been committed.

However, the xid given is in the future of the transaction table.

This could be due to a rollback segment corruption issue OR you might be hitting the following known problem.



If known issue (see below) this might cause missing data.
Otherwise, this could be a possible rollback segment corruption issue.

Some historic info….

Upgrade/install a patchset to bring the database to one of the following levels :,,
To avoid encountering this bug, rollback segments should only be dropped and recreatedaftertheinstancehasbeenshutdownnormalandrestarted. Ifyou have already encountered the bug, use the following workaround:
Possible workaround:
– Drop all rollback segments, except for SYSTEM
– Create the same number of rollback segments, small ones, with different names – recreate the original rollback segments
– drop the small dummy rollback segments
Every time you need to add a rollback segment, first create all of the dummy segments again, to make sure they use up the old segment numbers. Then create the new segment, then drop all dummy segments.
If you are getting this error not because of the above bug — see Description to see how you could run into the bug — then you might have a rollback segmentcorruptionissue.

ORA-600 [4097]
Versions:7.1.3 -7.3.2 Source:ktu.c =========================================================================== Meaning:

We are accessing a rollback segment header to see if a transaction has beencommitted. However,thexidgivenisinthefutureofthe transaction table. Ie: the WRAP of the XID is higher than
the current WRAP number on the RBS header.

————————————————————————— Argument Description:

No arguments.

————————————————————————— Diagnosis:

This should be considered as a corruption.

1. Try to identify which object has this TX in its ITL list. (see the trace file)


  1. If this object is recreatable that may be an option but we cant be sure whether it is the TX table that is too old or the block holding the ITL that is corrupt.
  2. You MAY be able to recreate the RBS – It is safest to force

    cleanout of all blocks before recreating the RBS (by FTS and recreating indexes).

Typical causes are media corruption to the data or RBS blocks, especially lost writes to RBS header.
This is also possible if rollback segments are recreated after a shutdownabort. SeeBug:427389 fordetails&options.Inthis case no data is corrupt, the rollback segments are just out of step.
