Hi Team,
We are having the cluster system (Windows 2008 R/2 , Oracle 11.2.0.2) in our landscape. We have to planned to upgrade to 11.2.0.3 of cluster production system as we have already done the non production instance to that level. I have downloaded the files from instguides and following the same. However certain things not been clear in the document for the Node B upgrade.
Let me explain my finding and procedure in nutshell:
Step 1 : I need to remove the OFS cluster group and need to ensure all the applciations and services are in node A
Step 2 : Need to install the oracle software with 11.2.0.3 in Node A
Step 3 : Will be preparing the post activities by running the script in Node A
Step 4 : Upgrading the oracle instance of Node A
Step 5 : Post activities of the upgrade like listener, statisctics and home directory etc.
Step 6 : Upgrade done
Step 7 : Need to do the same in node B activities from step 2 to step 6
Step 8 : Creating OFS group - with ECP.WORLD
Step 9: Upgrade / Clustering done and back to the normal state
Now my problem is starting with Step 7. In which i have upgraded the node A and all the activities are done (For the safer side started sap and ensured that things are fine in Node A)
But when I try to start the node B preparation - Queries are
1. Wondering - Do i need to move all the services and application to nodes B? before we start the installation of software?
2. I could see that Oracleservice<SID> and listeners are not available now - Is that cleared because of i have removed the OFS group? Shall I proceed with the installation of oracle and upgrade further without those service?
Please do advise me
Note : Before starting it, I have ensured that Node A can be moved to Node B without any issues - IT was working fine (Also SAP in node A and DB in Node B) for testing purpose
Regards
