Home -> Community -> Mailing Lists -> Oracle-L -> RE: 100 instances on same server !!!
Right now I have 37 instances on an hp-ux server,
a mix of 8.1.7.4 and 9.2.0.3

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 .
