We have 60 instances on one development box,
but that cannot be compared to production servers. I am not sure I
understand the base question. If you have adequate memory and cpu, I don't
think there is a known limit on instances. Of course, there are several
resource issues that come into play beyond cpu and memory such as the max
processes for the server itself, the number of spindles required to support 100
independent instances....

Right now I have 37 instances on an hp-ux
server,
a mix of 8.1.7.4 and 9.2.0.3

We are
pentium of Intel. Division is futile.
You will be approximated.
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
.
