comment What problems can be caused by dropping a rollback segment manually?
my spfile contains the following: crimesys1.undo_tablespace='UNDOTBS1' *.undo_tablespace='UNDOTBS' UNDOTBS is newly created undo tablespace, which I want to leave and delete other undo tablespaces.

@MindaugasRiauba dba_2pc_pending is empty now but, there is sometimes a record in gv$transaction referring to some of these segments.

@Phil Why do you think that shutdown abort may resolve the issue?

@Phil I changed UNDOTBS2 to any available undo tablespace name and still returns 0 rows. Maybe, it is now that no one uses, but will be used after a while.

When I query status column of dba_rollback_segs view, filtering by UNDOTBS2, it shows me that most of them are OFFLINE and others are PARTLY AVAILABLE. If I drop OFFLINE segments, why it should be a problem?

comment ORA-13901 Object UNDOTBS01 was not found. ORA-06512: at “SYS.DBMS_SERVER_ALERT”, line 7
@Phil I have the full installation of 11.2.0.3. Can I upgrade my 11.2.0.1 database using this installation? Or do I need to download the patch? Is the patch software different from the fresh installation? Does runInstaller of the fresh installation have the option like upgrade? And is the patch(11.2.0.1->11.2.0.3) different from the patch(11.2.0.2 to 11.2.0.3)?
