Drop & Create Temporary Tablespace in Oracle Database

Goal:

Following steps will help you to create a temporary tablespace in Oracle

1. Create Temporary Tablespace Temp

CREATE TEMPORARY TABLESPACE TEMP2 TEMPFILE   '/oracledb/oradata/stlbas/temp02.dbf' SIZE 2000M;

2. Move Default Database temp tablespace

ALTER DATABASE DEFAULT TEMPORARY TABLESPACE temp2;

3. Make sure No sessions are using your Old Temp tablespace

   a.  Find Session Number from V$SORT_USAGE:
       SELECT USERNAME, SESSION_NUM, SESSION_ADDR FROM V$SORT_USAGE;

   b.  Find Session ID from V$SESSION:

       If the resultset contains any tows then your next step will be to find the SID from the V$SESSION view. You can find session id by using SESSION_NUM or SESSION_ADDR from previous resultset.

       SELECT SID, SERIAL#, STATUS FROM V$SESSION WHERE SERIAL#=SESSION_NUM;
       OR
       SELECT SID, SERIAL#, STATUS FROM V$SESSION WHERE SADDR=SESSION_ADDR;

    c.  Kill Session:

    Now kill the session with IMMEDIATE.

    ALTER SYSTEM KILL 'SID,SERIAL#' IMMEDIATE;

4. Drop temp tablespace

DROP TABLESPACE temp INCLUDING CONTENTS AND DATAFILES;

5. Recreate Tablespace Temp

CREATE TEMPORARY TABLESPACE TEMP TEMPFILE  '/oracledb/oradata/stlbas/temp01.dbf' SIZE 10240M;

6 Move Tablespace Temp, back to new temp tablespace

ALTER DATABASE DEFAULT TEMPORARY TABLESPACE temp;

7. Drop temporary for tablespace temp

DROP TABLESPACE temp2 INCLUDING CONTENTS AND DATAFILES;
