Hi,

How to I set my database server to utilize the memory 12 GB Ram available on the server. Currently the database is configured using AWE to use 3 GB of data block buffers.
I have been monitoring the system for a while and I can see excessive paging occurring on the database server, how can I prevent this?
I am using 10gR2 on windows 2003 server.
Thanks,
Yash

Buy more memory
or
Tune the application to use less memory (make better use of available RAM).
or

There is more to memory use that buffer cache. Also look at the shared pool. But with 10gR2 you might consider sga_target.

Also check your pga_aggregate_target, lots of places have it at a mere 25mb which is far too low.

If I got the database parameters right then sga_target can't be used when we are using the database with use_indirect_data_buffers=TRUE and AWE enabled on the database. Please correct me if I am wrong in this.
Thanks,
Yash
