Rename/Move Datafile without putting Tablespace offline.

Labels: Move Datafile without offline, RMAN

Below is a Demo where I had to Move datafile . its always a best practice & safe to offline whole Tablespace. But sometimes we don't get that liberty. Just for experimental purpose I Move/rename single Datafile of Tablespace which has 8 more Datafiles. The method dont applied to database running on Noarchivelog mode,because Recovery will be needed.

if your listener is not running on default port. MAKE STATIC REGISTRATION OF AUXILIARY INSTANCE in LISTENER.
