How to Force Immediate Takeover of Oracle Data Guard Services by a Standby Cluster

Before You Begin

Before you force the standby cluster to assume the activity of the primary cluster, ensure that the following conditions are met:

• Sun Cluster Geographic Edition software is up and running on the cluster.

• The cluster is a member of a partnership.

• The Configuration status of the protection group is set to OK on the standby cluster.

1. Log in to a node in the standby cluster.

   To complete this step, you need to be assigned the Geo Management RBAC rights profile. For more information about RBAC, see Sun Cluster Geographic Edition Software and RBAC in Sun Cluster Geographic Edition System Administration Guide.

2. Initiate the takeover.

   phys-node-n# geopg takeover [-f] protectiongroupname

   -f

   Forces the command to perform the operation without your confirmation.

   protectiongroupname

   Specifies the name of the protection group.

Example 3–2 Forcing a Takeover by a Standby Cluster

This example shows how to force the takeover of sales-pg by the standby cluster cluster-newyork.

The node phys-newyork-1 is the first node of the standby cluster. For a reminder of which node is phys-newyork-1, see Example Sun Cluster Geographic Edition Cluster Configuration in Sun Cluster Geographic Edition System Administration Guide.

phys-newyork-1# geopg takeover -f sales-pg

Next Steps

For information about the state of the primary and the standby clusters after a takeover, see Appendix C, Takeover Postconditions, in Sun Cluster Geographic Edition System Administration Guide.
