    ORA-00600: internal error code, arguments: [6006]

    Article explains root cause of ORA-00600: internal error code, arguments: [6006] with workaround and solution.

    ORA-00600: internal error code, arguments: [6006], [1], [], [], [], [], [], []

    Our production database encountered with above Oracle error. Our database server was stuck after sending an error. We are able to select and perform some work using a superuser with sysdba privilege, but other users were unable to perform transactions.

    We checked Oracle support documentation and found a workaround for this bug.

    The error “ORA-00600: internal error code, arguments: [6006], [1], [], [], [], [], [], []” is received when problems with UNDO space occur.

    How to fix and what is the solution?

    Oracle support provides the following workaround.

    Making a new UNDO tablespace:

    create undo tablespace undotbs3 datafile ‘… / oracle / oradata / testdb / undotbs3.dbf ’size 400m;

    we define the problem segment using following SELECT query using SYSDBA privilege.

    select segment_name, status from dba_rollback_segs;

    Now we need to assign a new UNDO tablespace to the system:

    alter system set undo_tablespace = undotbs3 scope = both;

    In the init.ora initialization file, add the line:

    _corrupted_rollback_segments = ”_ SYSSMU3$” _SYSSMU3$ is our corrupted rollback segment.

    Load the database with our new init.ora parameter file using command startup pfile=<name with full destination of parameter file>

    Then we delete the damaged or corrupted rollback segment:

    drop rollback segment "_SYSSMU3$";
