ADD/Remove TEMP tablespace in oracle database

By
ADD/Remove TEMP tablespace in oracle database:-
=====================================

  To add new Temp tablespace and change it as default do follow below procedure.

1. First create New temptablespace and change it to default temp.

CREATE TEMPORARY TABLESPACE <NEW_TEMP_NAME> TEMPFILE '<teampfile location.dbf' SIZE 1000M AUTOEXTEND OFF
TABLESPACE GROUP ''
EXTENT MANAGEMENT LOCAL UNIFORM SIZE 1M;

ALTER DATABASE DEFAULT TEMPORARY TABLESPACE <NEW_TEMP_NAME>;


Remove the old temptable space , before remove you must check any session already in use or not.

to check use below query to get live session(SID&serial#)  those who use old temp.

SELECT b.tablespace,b.segfile#,b.segblk#,b.blocks,a.sid,a.serial#,
a.username,a.osuser, a.status
FROM v$session a,v$sort_usage b
WHERE a.saddr = b.session_addr;

THEN kill session if any session in use.

alter system kill session 'SID_NUMBER, SERIAL#';

we can drop old temporary tablespace.
DROP TABLESPACE TEMP including contents and datafiles;


Be careful while doing this in production.

ORA 700 [kskvmstatact: excessive swapping observed] ======================================== One of my database down suddenly. Reason:  ORA-700 SWAP error, as the dump it's taking more that 10 minutes pmon killed the process and the database was down. this database running with less memory . Solution alter system set "_kse_die_timeout"=XX or 0 if we want to disable the pmon killer during dumping . note: The error is documented in:  -  Note:1919850.1  - 12c: Warning Message About Heavy Swapping Observation and ORA-700 [kskvmstatact: excessive swapping observed]  Because your swap memory has low values of swap in / swap out, this warning message can be safely ignored.  Given both the alert log message and ORA-700 are expected behavior for 12c, no action is required.  An enhancement request (ER) was created to change the threshold in future releases in  Bug 19495842  - CHANGE THRESHOLD IN THE SWAP WARNING IN THE ALERT_<SID>.LOG  ==============
