The largest component of a PGA is the sort area size, and Oracle allows you to dynamically change the sort area size at the session level. alter session set sort_area_size= 5KB; for >=9i : When pga_aggregate_target parameter is set and you are using dedicated Oracle connections, Oracle9i will ignore all of the PGA parameters in the init.ora file, including sort_area_size and sort_area_retained_size. Hi Mate,
The PGA consists of
* Sort area – This is the largest and most important area of the PGA
* Session information – This small area contains internal address for the connection to allow the connection to communicate with Oracle.
* Cursor state – This component of the PGA contains all reentrant values for the executing connection.
* Stack space – This area contains miscellaneous control structures.

The largest component of a PGA is the sort area size, and Oracle allows you to dynamically change the sort area size at the session level.
alter session set sort_area_size= 5KB;

for >=9i : When pga_aggregate_target parameter is set and you are using dedicated Oracle connections, Oracle9i will ignore all of the PGA parameters in the init.ora file, including sort_area_size and sort_area_retained_size.

Can I have one of my question? When user connect to server...Pmon process start and memory allocated for that user session from PGA rite? then can I have any type of configuration support to which I can assign like 5KB to each user process? Do let me know. Thanks... Hi Sagar,

nice script.

Can I have one of my question?

When user connect to server…Pmon process start and memory allocated for that user session from PGA rite?

then can I have any type of configuration support to which I can assign like 5KB to each user process?
