Symptoms

RMAN restore fails with errors like the following:

 

This error can happen for any datafiles. However, it is a major concern if it is datafile 1. Datafile 1 is the system datafile. It cannot be CREATED during an RMAN restore. It must RESTORED from a backup. Therefore we must look to see why it cannot be restored in the first place.

Often the  error is not a problem with RMAN unable to write to the destination drive as one might think by looking at the error message "can not create datafile 1".
