Multiple databases in a cluster is certainly supported, and something lots of companies do. The decision of whether do proceed this way would depend on a number of factors (aggregate CPU requirements per database, interconnect chattiness per DB, maybe switch capabilities/capacities, how easy or hard it may be to provision storage for another set of clusterware, etc ...) - John

Subject: Multiple databases in a RAC
Oracle 11.2.0.2
AIX 6.1
Peoplesoft HCM + ELM
We have an existing 11.2.0.2 RAC + GRID cluster built to run Peoplesoft
HCM.
2 nodes....active/active.
We have been asked to install another Peoplesoft module (ELM).
My recommendation was to construct a 2nd cluster to support the 2nd module
and its database.
So........I would end up with 4 nodes (2 for the HCM cluster and 2 for the
ELM cluster)
and these clusters would be distinct.
I am being asked if it is possible to install the new ELM product on the
existing nodes.
That is..........a 2-node RAC cluster with 2 distinct databases and 4
instances.
This is not making much sense to me.....I am not even sure if this is supported/feasible.
Looking for ideas on this.
Any input appreciated.
Thanks.
