Hi:
Oracle 8173 on Solaris 2.8.
I am trying to convert temp tablespace to LMT. My plan is to
1.create another temp tablespace temp123
2.move all users to temp123
3.alter tablespace temp offline
4.drop tablespace temp
5.re-create temp tablespace as LMT
6.move all users to temp
7.drop tablespace temp123.
But I am having problem in Step4. I found that there are still some objects
in temp ts even if I put it offline:
[EMAIL PROTECTED]> select count(*) from dba_segments where
tablespace_name='TEMP';
COUNT(*)
----------
1
"drop tablespace temp" resulted in "ORA-01549 tablespace not empty, use
INCLUDING CONTENTS option". However when I did
drop tablespace temp INCLUDING CONTENTS;
the sqlplus session just hang and I kept getting the same count(*) from the
following query (from another session)
[EMAIL PROTECTED]> select count(*) from fet$ where ts# = 3;
COUNT(*)
----------
214
I eventually killed the orginal sqlplus session.
I did "ALTER TABLESPACE TEMP coalesce" and it did not seem to help.
So my question is: How can I drop an offlined temp tablespace when there is
still segment(s) in it?
I don't know if SMON would clean up the temp ts automatically (Some doc says
SMON would not do to TEMP ts). I also read that I could issue
alter session set events 'immediate trace name DROP_SEGMENTS level 3';
to mimic SMON, becuase
[EMAIL PROTECTED]> select name, ts# from ts$ where NAME='TEMP';
NAME TS#
------------------------------ ----------
TEMP 2
But I am not ready to try it on our production system. Has anyone tries this
or has any suggestions? I don't want to bounce db. Would the objects in TEMP
ts be cleaned up by SMON if I wait for a couple of days?
TIA.
