Upgrade on Unix Cluster
I have completed Oracle/SAP Upgrade on Veritas cluster Unix environment on Node A.
Now after starting the Cluster. I am unable to login to SAP Application.
I am mentioning the approch I followed at High Level:
1) Switching off Node B.
2) Renamed SAP profiles to point to host of Node A
3) Upgrade Oracle 9x to 10g - completed
4) Upgrade SAP CRM 4 to SAP CRM 5 - completed
5) Start/Stop of the DB and SAP works fine on Node A
6) Renamed all SAP profiles and hostnames in the profiles back to Cluster Hostname.
7) DB is up and running but not SAP Application is not coming up
Do you think I missed out anything ? Pls advice.
