Hi Alywin,

Welcome to the Oracle Analytics community and thanks for your question@

You cannot install a second OAS into the same RCU schema.

You may be confusing High Availability (HA) using scale-out as documented in the OAS Enterprise Deployment Guide or the OAS Administration Guide with Disaster Recover (DR) failover.

Hello,

Active/ Active, Active/ Passive is design choice, that depends on how you want to steer the traffic.

Here is blog on DR, which will gives design guidelines

Alwyn Paes

so here are my concerns

Scale Horizontally within same Data Center, primary server which has admin running goes down, the second server is of no use
in case of DR, is there a way to achieve without using the same hostname in DR?
