Hi,

What are the tipical tips about the value of UNIFORM SIZE that I can get if creating a Temporary Tablespace with a tempfile and locally managed defined temporary tablespace (I can't set it to AUTOALOCATE as I'm using Oracle 8i which does not support the AUTOALLOCATE option!!)??

CREATE TEMPORARY TABLESPACE TBS_name

TEMPFILE 'path....'

EXTENT MANAGEMENT LOCAL UNIFORM SIZE XM;

What are the performance tips or criteria to evaluate X??

Thank you very much!

Regards,

Patrick.

Hi
set the UNIFORM extent size to be the same as your SORT_AREA_SIZE or multiples of it.
Yes, you cant AUTOALLOCATE extents in a Locally Managed TEMPORARY tablespace ,as the extents are allocated once and reused thereafter until the instance shutsdown.
