The role of RMAN in this scenario, does not

I don't think that the steps mentioning ALTER SYSTEM SUSPEND/RESUME and
ALTER TABLESPACE BEGIN/END BACKUP are necessary if IBM Flashcopy can support
splits of non-quiesced volumes (ask your AIX SA). If it
Gene - Hopefully someone will have better ideas than these, but I'll make a

RMAN can issue SQL commands to your target database, so you could try
having it issue the alter tablespace command. Then after you do the backup
you could register the backup with RMAN. Almost

for your suggestions. So it appears in my environment, I am best off
sticking w/ my trusty hot backup scripts. Using RMAN for 3rd mirror splits
doesn't appear to benefit me. Using RMAN to backup to a 3rd mirror would

The more the better the RMAN advantage.
