datafile movement from one diskgroup to another
I am trying to move the datafiles from one diskgroup to another.
at first we are trying to do use rman and the sintax we used is
backup as copy datafile 5 format "+DATAJDE"
but when the process starts i get the following error
RMAN-03009: failure of backup command on ORA_DISK_1 channel at 10-29-2011
RMAN-10038: database session for channel ORA_DISK_1 terminated unexpectedly
we have just installed the database with oracle asm and we are using rman as it comes
So my question is if i need to configure some special parameters in order for the rman command to work
