[grid@myrac04 ~]$ olsnodes -n
myrac01 1
myrac02 2
myrac04 3
myrac03 4
After installing GRID and RAC i ended up with this node assignment.
Instance 3 is on node4 and instance 4 is on node3.
I wanted to switch Node3 and Node4 ASM and DB instances so the numbering is in sync.
I checked the /etc/hosts and DNS entries and everything is OK (proper hostname IP mapping is fine and not interchanged)
SIDs in bash_profiles are properly set too.
What could have caused the numbering to be off?
Is there a way to do it switch instances between nodes?
