Connect other standby clusters after a lossless failover

This topic describes how to connect other standby clusters in the DISABLED state to the new primary cluster after a lossless failover.

Procedure

On the new primary cluster, enable synchronization to other standby clusters.

1. Log on to the new primary cluster and execute the following statement to enable synchronization to standby clusters:

   obclient> ALTER SYSTEM ENABLE CLUSTER SYNCHRONIZATION 'obcluster' CLUSTER_ID=3;
   

2. Verify that synchronization is enabled.

   obclient> SELECT CLUSTER_ID, CLUSTER_ROLE, CLUSTER_STATUS FROM V$OB_STANDBY_STATUS;
   +------------+------------------+----------------+
   | CLUSTER_ID | CLUSTER_ROLE     | CLUSTER_STATUS |
   +------------+------------------+----------------+
   | 3          | PHYSICAL STANDBY | VALID          |
   +------------+------------------+----------------+
   1 row in set
