Resynchronizing an Oracle Data Guard Protection Group

You can resynchronize the configuration information of the local protection group with the configuration information that you retrieve from the partner cluster. The cluster on which you run the command to resynchronize forfeits its own protection group configuration of the partner cluster. To determine if you need to resynchronize a protection group, you use the geoadm status command. If the value of the Synchronization parameter for a protection group is listed as Error, you need to resynchronize the protection group.

For example, you might need to resynchronize protection groups after booting the cluster. For more information, see Booting a Cluster in Sun Cluster Geographic Edition System Administration Guide.

Resynchronizing a protection group updates only entities that are related to Sun Cluster Geographic Edition. For information about how to update Sun Cluster entities, see Replicating and Upgrading Configuration Data for Resource Groups, Resource Types, and Resources in Sun Cluster Data Services Planning and Administration Guide for Solaris OS.

How to Resynchronize an Oracle Data Guard Protection Group

Before You Begin

You need to deactivate the protection group on the cluster where you run the geopg update command.

1. Log in to a cluster node.

   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. Resynchronize the protection group.

   phys-node-n# geopg update protectiongroupname
