Re: Server Architecture

We mostly use this architecture in production, i.e. one Unix account and set of binaries per instance. It has plusses and minuses. The plus is when application A needs a patch, but applications B through E do not. With one set of binaries, the patch needs to be tested (in theory) on all applications.

Or, Application A is on Oracle 9i and is upgraded to a new version that requires 10g. But, applications B through E aren't supported on 10g. Or are supported on 10.2.0.1, but not 10.2.0.3.

In my experience, the problems are endless.

We also use Veritas clustering software and have the need to failover individual databases to a different server. I'm not sure how that would be done without each database having it's own Oracle binaries, listener, etc.

This architecture was decided before I arrived. I've done it both ways and to me, this way has less headaches.
