Proper procedure for removing Rollback Segments

in Database Administration (MOSC) 4 commentsAnswered ✓

Hello everyone,

Ready for a blast from the past?!

I've recently begun managing a database running Oracle Enterprise Edition 12.1.0.2. I've just discovered that the database still has "Rollback Segments" in place. The database also has an UNDO tablespace and the following parameters/values:

undo_management               string   AUTO                                                 

undo_retention               integer   1800                                                 

undo_tablespace               string   UNDO_TBS

As far as I can tell, having both rollback segments and automatic undo management is (if not actually bad) completely pointless. Since undo_management is already set to auto, is there anything else I need to do to ensure that automatic undo management is fully up and running?

Howdy, Stranger!
