We are planning to make a small change in the Linux file system. To be on the safe side, I thought I would take a SAN-level snapshot of all the drives beforehand. I was thinking I should put the Oracle database in backup mode:
Alter system archive log current; Alter database begin backup; -- after the SAN snapshot finish-- Alter database end backup; Alter system archive log current;
Someone said this command is deprecated from 9i.
My question is, if I go ahead and use this, will it be ok? Or is there another way to do this?
Note: I don't want to use RMAN's full backup as this will take 6 hours.
