Re: oracleas 10gR2 backup

Hi

I spend sometime debugging the perl script this weekend and I found out that there is no difference between

*bkp_restore.sh -m backup_config* and

*bkp_restore.sh -m backup_instance_online (I Really meant instance_online and not online only sorry!)*

They are the same! There is a function called getbackupopt or smomething like that which says

if xxx == backup_instance_online
then
  backup_opt = backup_config

etc etc etc.

basically backup_online/offline is for database

backup_instance_online/offline == backup_config + backup_online/offline

cheers
