Home -> Community -> Mailing Lists -> Oracle-L -> RE: Running multiple instances on a [large] server
Hi,
On one of the 7 development box (aix 4.3.3) we have 27 instances Oracle
8172.
All using the same oracle_home.
I can't say it's the fastest response time ;-)
As for the licensing we have a mix of CPU and user licences.

One of the teams here is planning to run anything from 8 to 16 database instances [no indication on sizing yet, but gut-feel SGAs are 200MB to 1GB and DB sizes 500MB to 40GB] on a "large" server, something like a Sun E6800 or an equivalent HP or Fujitsu server.
My positioning is
a. We might not be able to create 8 partitions but
partition such that we have a max of 2 or 3 instances
in one partition. Hopefully, I can dynamically change
CPU partitioning to reallocate CPU to another group
of instances.
b. Each instance should have it's own ORACLE_HOME. [Disk space is not a constraint].
c. Just add up the number of CPUs on the server, across all partitions, and buy a CPU license. Also, a CPU license is much preferable to Named-User as some of these databases would host Portals for 1,000+ end-users.
