RE: Temporary Tablespaces

Les, If the temp tablespace is created using tempfiles which are in turn "re-created" every time the instance is started how is it that pmon has to clean up a log of small extents each time the instance starts? What extents?

1. create default temporary tablespace tspacename

CREATE TEMPORARY TABLESPACE temp
TEMPFILE '/u01/oradata/temp01.dbf' SIZE 500M EXTENT MANAGEMENT LOCAL UNIFORM SIZE 4M; =20 (Set your uniform size to a reasonable size based on your database size. DO NOT use small extents. Use 5m, 10m, even up to 100m if your tspace is large enough If you set it too small, you run in to the iissue of PMON running a long time to clean up the huge number of small extents each time the instance starts.)

After tablespace is created,=20

ALTER DATABASE=20
DEFAULT TEMPORARY TABLESPACE temp;
