The appilication is regular sql nothing fansier. It uses the net8 to interact with the instance.

I wounder whether there is a way to find out what is causing this low hit ratio. In short, the application that uses the OCI would make connection to the database and would use the database tables to keep track of IMP logins and sessions on the database. When ever a user opens/reads their email on the internet, the program would insert/update or select the data from the table.

Thats all the program does on the database side. I wonder whether there are any ways to find out where the contention for the Buffer cache lies at.

Thanx,
Sam
