List,

I would like to have your opinion on the following scenario.

We are having an application which is used by different customers (around 15 customers). On an average each customer will have around 1,000 transactions per 5 minutes. Now, is it better to have a separate database for each customer on the same machine or to create all the customers as different schema in one single database?

What are the pros and cons. I am specifically looking at performance and security issues.

Environment:

This application is a 24x7 environment, OLTP application. Sun 6500 Solaris 7 with 4 CPUS. Raid 10. Memory 4 GB (memory can be increased if required). Oracle 816.

Thanks,

Rao
