Oracle notes: raccroschecking

When Crosschecking is used on multiple nodes, you can configure the cluster so that each node in the cluster can access all Database backups, regardless of who generates the database backup.

When you use Crosschecking on multiple nodes, you can configure the cluster so that each node in the cluster can access all Database backups, regardless of who generated the database backup. If your cluster is configured like this, you can allocate channels on any node during restore or crosscheck operations ).

If you do not CONFIGURE the cluster as mentioned above, you must use the CONNECT option of the configure channel command to allocate channels on multiple nodes during restore or crosscheck operations ), so that each backup can be accessed by at least one node in the cluster.
If no channel is configured for access to these backups during the crosscheck operation, these backups will be marked as EXPIRED.

Node 1 and node 2 both use the default configuration and perform a full backup on node 1.

Configure the degree of parallelism to 2 (number of nodes) on node 2, configure the channel, and then verify again
