We are planning to upgrade DB2 from 9.1 to 9.7 FP5 in our Production system on cluster on HP-UX.
We already did it for our DEV and QAS systems but do not have much idea about cluster environment,
So please let me know the prerequisites / post upgrade or cluster specific steps need to be done for DB2 upgrade.
Since we will not get much downtime for PRD so want to prepare and plan accordingly before starting it on PRD.
Please provide your help.
