Hi,
I am trying to make some rollback segments to offline, but it is not happening. Can anyone guide me. Find below the commands;
SQL> alter rollback segment SYSSMU1 offline;
Rollback segment altered.
SQL> SELECT segment_name,status FROM dba_rollback_segs;
SEGMENT_NAME STATUS
------------------------------ ----------------

_SYSSMU1$ ONLINE
_SYSSMU2$ ONLINE
_SYSSMU3$ ONLINE
_SYSSMU4$ ONLINE
_SYSSMU5$ ONLINE
_SYSSMU6$ ONLINE

You are using automatic undo management feature, why do you want to manage the undo/rollback segments?
Either you are automatic, either you are manual, you can't be both.
Don't touch these segments.

Michel
