9iAS Cluster Distance Limitation

We will be deploying an application using oracle 9iAS and Oracle 9i on a Unix platform (not known yet). The application will be deployed in 2 data centers that are about 110-130 miles apart. The proposed architecture is as follows:

  Regional database X 2 (one at each data center)   9iAS software cluster X 2 (one at each data center)   9iAS infrastructure X 2 (one for each 9iAS cluster)

There will be cross regional transactions, so one 9iAS cluster will access
the other region's database. The application is one (the same) for both regions. So it has to be deployed twice with every code change.

1. Are there any benefits of having 2 different 9iAS clusters and infrastructures?
2. Instead, is it possible to have a single 9iAS cluster running on dispersed machines at both centers and managed by a single infrastructure that will reside at a single data center even though the distance is about 130 miles.

The existing architecture calls for each 9iAS cluster to be running on 3 servers with software clustering at each data center and the infrastructure to be software clustered on 2 additional machines at each data center.

Caveat: Having a single database for both regions is NOT an option.

I hope I explained it well. Received on Thu Oct 02 2003 - 09:49:01 CDT
