Oracle Undo Tablespace Keeps Growing

by Mar 27, 2013

I know this is more of an Oracle question, but figured I'd ask here as it may be something in the app. My undo tablespace keeps growing and I keep having to add datafiles. It is now up to 50GB. I am fairly new to Oracle, but from what I understand, the undo tablespace needs to be large on databases that have very large transactions, which I didn't think UPTIME had. I am running 11G, so I think there is some builtin management of undo size. Just wanted to ask here for anyone running on Oracle. What is the size of your undo Tablespaces? Any settings recommendations?
