Hi,
We current have two middleware servers (1 master and 1 salve) and oracle database in the primary site.
Our goal is to stand up a DR site so in case everything is down in primary site, we can fail over to DR without data loss, and with minimum or no downtime.
We have enabled Data Guard between primary and DR site, so now there is a standby database (read only) database in DR. Our next step is to stand up two middleware servers (1 master and 1 slave) in DR site.
Before we configure the two middleware servers in DR, we first shutdown IFS servers and services on the middleware server in Primary and switch over the oracle database which will make Primary as Standby, and Standby as Primary. Then we configure the two middleware server (Master (AdminServer) and Slave) . At this point, DR site should be fully functional.
Then we will shutdown IFS servers and services on the middleware server in DR and switch over the oracle database back to the Primary.
So in case failover happened, the standby database will become primary, and we just need to start the IFS servers and services on the middleware server in DR.
Can you please confirm this approach is workable?
