    EXP-00001 Error

    I'm attempting to do an export of my entire database. I get this dreaded EXP-00003 error. It appears to be in a rollback segment.

    I recently converted all tablespaces except SYSTEM and TEMP to locally managed using the DBMS utility.

    Any ideas on what to do?

    It looks like the problem is in your roll back segment 3.

    Run the following querry and confirm it
    Code:
            select * from dba_rollback_segs;
    Check all the storage definitions.

    Code:
            Select * from dba_rollback_segs 
                  where segment_id = 3;
    Does it look like the rest?

    If different look at the segment_name. Try taking that segment off-line.
    Code:
             alter rollback segment  segment_name offline; 
    
                select status from dba_rollback_segs 
                     where segment_name = 'SEGMENT_NAME';
    It must be OFFLINE.
    Then drop that rollback segment. Re-try your FULL export. If the ROLLBACK segment will not go offline, then export using USERS.

    Cool EXP FAILING EXP-00003: no storage definition found for segment(3, 2)

    The same situation is being reproduced in 8.1.7 on NT platform.
    since i had converted the extent management to llocal the error was caused.
    The error was rectified by converting the extent management of the tablespace (RBS) from locally to Dictionary management and then taking a export .
