Thanks for the replies so far. Considering the fact that my database is tiny ( just around 3 GB ), How many of them can work on same server? I can just test with 5 instances, with limited hardware. Will the CPUs be able to take load of 100 instances? Is it worth experimenting this?

I am on 8.1.7.4 and the application is already built. I stand no chance of changing the code. That is why using individual schemas for individual users is not an option. Right now I am just asked if 100 instances can run on same server and I don't have solid answer.

Just on side note, can I ask, What is the maximum number of instances anyone has ever worked/heard being installed with in same server?

Thanks again.

Dilip.

100 instances wohhhhh . If you are in 9i look at possibilities like context or label security . or creating another schema .
