ORA-00600: internal error code, arguments: [kkdlron-max-objid], [4254950911], [4254950914]

When the database reached maximum object id or if the new object id exceeds the limit you will see below error. This situation normally happen in Data ware house databases, especially with SAP BW using Oracle as database.

< ORA-00600: internal error code, arguments: [kkdlron-max-objid], [4254950911], [4254950914], [], [], [], [], [], [], [], [], [] < ORA-00600: internal error code, arguments: [kewrose_1], [600]

You will get the max object id by running below commands.
SQL> select max(obj#) from SYS.obj$;
SQL> SELECT dataobj# FROM sys.obj$ where name='_NEXT_OBJECT';
SQL> select max(object_id),max(DATA_OBJECT_ID) from dba_objects ;

Oracle Support Document 20529650.8 (Bug 20529650 - ORA-600 [kkdlron-max-objid], [4254950911]) can be found at:

Also check SAP note : 2137109 - Data Object ID limit , if you see the issue on SAP related applications.

I see 2 options here
1. Logically rebuild the DB - Permanent fix
2. Apply the patch 20529650 - workaround/temporary fix

The option 2 applying the patch will brings us the new limit 4293950911 (4254950911+39000000). But keep in mind that this new limit can reach quickly in BW systems. Note that the patch will give team some time but the permanent solution is to rebuilding the database.

You can use below query to estimate how much time you might have , but note that this is just an estimate only.
