We are planning for HA in our project. Our SAP setup is as below..
I have gone thru the Installtion manual and collective note on HA
-- it is a 3 system landscape with HA for production server.
-- AIX - 5.3, ORACLE 10G, SAP SR3, dual stack (ABAP + JAVA)
We are going for 2 sytems for production. We want simple HA solution.
I have planned as below.. Pls. correct me if I am wrong..
1. On one node ( Node -A) - I will choose HA Installation from "sapisnt" , it will install ASCS ( standalone enque and message server), I will configure Enque Replication Server (ERS)
2. Dialog instance on other node (Node - B) -
3. IBM HA will sit on Node - A
4. OS guys will help in maping the failover clusters..
Is my understading is correct ?..
