I migrated a 4 instance RAC database from a 4 node server to a 3 node RAC database server. However, I still have the 4th undo tablespace and the 4th redo log thread. Are there any precautions I need to take before dropping the 4th undo tablespace? Must I also drop the 4th redo log thread, or will the database function properly even without a 4th node to go with the 4th thread?

I presume I have to also disable the 4th public thread? Is this the command below?

Alter database disable public thread=4;

Yes, you should disable the thread of the fourth node with the command you posted and drop the undo tablespace associated with the fourth node.
