Dear All,
I have aproduction database, which is of 1 tera bytes.
So have mirrored the database filesystems to a new server and initiated a backup from rman.
the steps are below.
1) registed production database in catalog
2) backup controlfile from production befor begin backup.
database in backup mode
3) start the mirror copy to backup server.
4) once the copy completes end backup
5) in backup server (mirror copy of prod database),
a) mount the database with backup control file in backup server
b) start the backup through rman.
wile doing so we are facing the below error.
executing command: SET SNAPSHOT
