Good point Dennis - version issues. We create a separate Oracle home for each 3rd party application that we install at our company for this very reason.
Jay >>> [EMAIL PROTECTED] 08/02/02 01:05PM >>> Ethan - Now that you have clarified the reason why you want 20 instances, I'll change my advice and say that in your situation, 20 instances may be the better choice. Two other factors you need to consider: 1. An ASP is a lot like the old time-sharing systems. You must have an absolutely bulletproof billing system. This may be easier to accomplish if you have each customer in a separate O.S. username. You might be able to use the O.S. usage reports for billing with separate userids. And you must have good security to keep them from becoming root and giving themselves a discount. 2. Eventually you will need to upgrade Oracle versions. Not all customers will be able to upgrade at the same time due to other constraints on their part. Separate instances will allow you to have different customers on different Oracle versions.
