Oracle Database Discussions

Api,

You can simply create new temporary tablespace in new location and set it as default temporarty tablespace. And similar you can do that with undo tablespace

sqlplus '/as sysdba'


SQL>CREATE TEMPORARY TABLESPACE temp2   TEMPFILE '/new_location/temp2_01.dbf' SIZE 64M REUSE AUTOEXTEND ON NEXT 28 MAXSIZE unlimited;

SQL>ALTER DATABASE DEFAULT TEMPORARY TABLESPACE temp2

#drop old temp tablespace
SQL>DROP TABLESPACE temp INCLUDING CONTENTS AND DATAFILES;


#undo tablespace

SQL>create undo tablespace undotbs2 datafile '/new_location/newundo02.dbf' size 2000m;

#Set new tablespace as undo tablespace
SQL> alter system set undo_tablespace= undotbs2 ;

#Drop old undotbs tablespace
SQL> drop tablespace undotbs including contents;

Regards

Create new UNDO & TEMP tablespaces, switch to new TS, & then drop old ones.

About create/change/drop

UNDO:

SQL>show parameter undo

NAME TYPE VALUE
------------------------------------
undo_management string AUTO
undo_retention integer 900
undo_tablespace string UNDOTBS1

SQL> CREATE UNDO TABLESPACE undotbs2 DATAFILE '+DATA_NEWPATH' SIZE 100M AUTOEXTEND ON;

http://www.oracle-base.com/articles/9i/AutomaticUndoManagement.php

SQL> alter system set undo_tablespace=undotbs2;

*** after that can drop UNDOTBS1

TEMP:
SQL> CREATE TEMPORARY TABLESPACE TEMP TEMPFILE '+DATA_NEWPATH' SIZE 500M AUTOEXTEND ON NEXT 100M MAXSIZE unlimited EXTENT MANAGEMENT LOCAL UNIFORM SIZE 1M;

http://www.idevelopment.info/data/Oracle/DBA_tips/Tablespaces/TBS_3.shtml

SQL> ALTER DATABASE DEFAULT TEMPORARY TABLESPACE temp2;


*** after that can drop old temp tablespace -> DROP TABLESPACE temp INCLUDING CONTENTS AND DATAFILES

Ya thanks a lot for the answer but I have one more query...

Mine is the production server and I can't shutdown so may I do all this operation when database is open?

How do I know that users are accessing the old Undo tablespace or temporary tablespace or not, because after checking that no one is using the old ones, I can drop it. So when can I drop old undo and temp tablespaces?

If you are trying to drop these tablespace ..which is being use by some transactions ..oracle will not allow to do that..
Read some documents on google ..thay will clear you doubts also..

enjoy
