## Creating a Protection Group That Does Not Require Data Replication

Some protection groups do not require data replication. If you are using the Geographic Edition software to manage only resource groups, you can create protection groups that do not replicate data. The `geoadm status` command displays that these protection groups are in the `Degraded` state. This section describes how to configure your protection group not to use data replication.

Note - You cannot add device groups to a protection group that does not use data replication.

## How to Create a Protection Group That Is Configured Not to Use Data Replication

Before You Begin

Before you create a protection group, ensure that the following conditions are met:

- The local cluster is a member of a partnership.

- The protection group that you are creating does not already exist.

Note - Protection group names are unique in the global Geographic Edition namespace. You cannot use the same protection group name in more than one partnership on the same system.

1. Become superuser or assume a role that is assigned the Geo Management RBAC rights profile.

   For more information about RBAC, see Geographic Edition Software and RBAC.

   Note - If you use a role with Geo Management RBAC rights, ensure that the `/var/cluster/geo` ACLs are correct on each node of both partner clusters. If necessary, become superuser on the cluster node and set the correct ACLs.

       # chmod A+user:username:rwx:allow /var/cluster/geo

   The `/var/cluster/geo` directory must have the correct access control lists (ACL) applied for compatibility between the Geo Management RBAC rights profile and Oracle Data Guard.

2. Create a new protection group by using the `geopg create` command.

   This command creates a protection group on the local cluster.

       # geopg create -s partnershipname -o localrole \
       [-p property [-p…]] \
       protectiongroupname

   `-s` partnershipname

     Specifies the name of the partnership.

   `-o` localrole

     Specifies the role of this protection group on the local cluster as either `Primary` or `Secondary`.

   `-p` propertysetting

     Specifies the properties of the protection group.

     You can specify the following properties:

     - `Description` – Describes the protection group.

     - `External_Dependency_Allowed` – Specifies whether to allow any dependencies between resource groups and resources that belong to this protection group and resource groups and resources that do not belong to this protection group.

     - `RoleChange_ActionArgs` – Specifies a string that follows system-defined arguments at the end of the command line when the role-change callback command runs.

     - `RoleChange_ActionCmd` – Specifies the path to an executable command. This script is invoked during a switchover or takeover on the new primary cluster when the protection group is started on the new primary cluster. The script is invoked on the new primary cluster after the data replication role changes from secondary to primary and before the application resource groups are brought online. If the data replication role change does not succeed, then the script is not called.

       This path should be valid on all nodes of all partner clusters that can host the protection group.

     - `Timeout` – Specifies the timeout period for the protection group in seconds. You can change the timeout period from the default value depending on the complexity of your data replication configuration. For more information on setting the timeout period, see Table A-4.

     For more information about the properties you can set, see Appendix A, Standard Geographic Edition Properties.

   protectiongroupname

     Specifies the name of the protection group.

   For information about the names and values that are supported by Geographic Edition software, see Appendix B, Legal Names and Values of Geographic Edition Entities.

   For more information about the `geopg` command, refer to the `geopg`(1M) man page.

Example 7-1 Creating and Configuring a Protection Group That Is Configured to Not Use Data Replication

This example creates a protection group that is configured to not use data replication.

    # geopg create -s paris-newyork-ps -o primary example-pg
