Using same tablespace as permanent and temporary tablespace
I have a database to manage ( ORACLE 11GR2 on solaris 5.1 )
Recently I found out that , one tablespace was assigned as default tablespaces of some users ( which is a permanent tablespace) and
same table is assigned as a temporary tablespace of some other users.
I want to know that is there any risks or important facts to known about this situation.
Also ,I want to know is there a way to resolve this with minimum downtime.
Note that this database is very critical and required 24*7 availability. So down time is one of a last option.
