The Oracle Grid Infrastructure administrator runs ocrconfig -backupioc <new_location> after
completing the installation of the Grid Infrastructure. What are the two reasons for doing this
A.
The cluster node currently acting as the master node for CRS is the only node that backs
up the OCR to the default location, and by changing the location, all cluster nodes will then
take backups.
B.
This is done to move the backup location into an ASM Cluster File System directory so
that the backups benefit from ASM striping and mirroring.
C.
If for any reason CRS must be stopped on all nodes for a time spanning a scheduled
backup, then on restart, the backup timer will be reset. This could result in longer time
duration between automatic backups than the standard four-hour interval.
D.
The master node may change if the node running the master CRS daemon shuts down
causing another node to become the master. Because the default location is a nonshared
storage, and only the master node performs backups, the backups could be spread around
on many nodes making management or recovery more difficult.
