How to Delete an Application Resource Group From an Oracle Data Guard Protection Group

You can remove an application resource group from a protection group without altering the state or contents of the application resource group. You can remove Oracle shadow RAC server proxy resource groups at any time, without affecting the Oracle RAC server proxy resource groups or Oracle RAC databases that they represent. You can remove these resource groups because the shadow RAC server proxy resource groups simply reflect the status of the real Oracle RAC server proxy resource groups and do not control the Oracle RAC databases.

Before You Begin

Ensure that the following conditions are met:

• The protection group is defined on the local cluster.

• The resource group to remove is part of the application resource groups of the protection group. For example, you cannot remove a resource group that belongs to the data replication management entity.

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, seeSun Cluster Geographic Edition Software and RBAC in Sun Cluster Geographic Edition System Administration Guide.

2. Remove the application resource group from the protection group.

   phys-node-n# geopg remove-resource-group resourcegrouplist protectiongroup

   resourcegrouplist

   Specifies the name of the application resource group.

   You can specify more than one resource group in a comma-separated list.

   protectiongroup

   Specifies the name of the protection group.

   This command removes an application resource group from a protection group on the local cluster. If the partner cluster contains a protection group of the same name, the application resource group is also removed from the protection group of the partner cluster.

   If the resource group that is being removed shares dependencies with other resource groups in the protection group and the External_Dependency_Allowed protection group property is set to FALSE, you also need to remove all other resource groups that share dependencies with the resource group that is being removed.

   If the remove operation fails on the local cluster, the configuration of the protection group is not modified. Otherwise, the Configuration is removed and its status is set to OK on the local cluster.

   If the Configuration status is set to OK on the local cluster, but the remove operation is unsuccessful on the partner cluster, the Configuration is removed from the partner cluster and the configuration status is set to Error on the partner cluster.
