For example in the step 2 below, is this run from RMAN or from SVRMGRL?

1 -Start RMAN and connect to the target database and, optionally, the recovery catalog database. For example, enter:

% rman target / catalog rman/rman@rcat



2- If the database is open, shut it down and then mount it:

shutdown immediate;
startup mount;



3 - After allocating channels, restore the database:

run {
allocate channel ch1 type disk;
allocate channel ch2 type disk;
allocate channel ch3 type disk;
restore database;
}
