oracle 10 on sun solaris 10 64 bit.
I am using redo and rollback and per another issue was told the best approach is to use an undo tablespace - have been reading up on it but need some quick clarifications to proceed.
Does the undo tablespace replace redo or rollback or both?
Does the database have to be bounced to implement?
Does autoextend have to be on?
Can you turn autoextend off/on as needed?
What is the best size/next/maxsize for long running queries and can this be adjusted on the fly?
When the undo tablespace is created should I get rid of the rollback tablespace or the redo tablespace?
