Dear All,
We are trying to implement SAP HA Active/Active.
The application servers will have HA on Active/Active and the database servers are going to be active/passive using Oracle Dataguard.
As per the proposal put forward by our implementors, we need 3 application nodes or servers.
Out of the 3 nodes, only 1 node will have an active CI.
The other components will be active on all the 3 nodes.
However the CI component when it fails, it must automatically failover to the next node (N+1).
So this must be managed via the HACMP from the OS side for clustering.
Now we have heard from people that usually the CI component is setup on the passive node of the database server which is managed by the HACMP.
So the app nodes are running in parallel using load balancer and the CI will run on the passive node of the DB server which is managed by the HACMP.
How true is this? What is the proper architecture please?
Thanks and Regards,
Augustine
