## Modifying a Heartbeat Plug-in Property

This section describes procedures for modifying heartbeat plug-in properties. When you modify a plug-in property, your changes take effect immediately.

## How to Modify the Properties of a Heartbeat Plug-in

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. Modify the heartbeat plug-in properties.

       # geohb modify-plugin -p propertysetting \
       [-p…] pluginname heartbeatname

   heartbeatname

     Specifies an identifier for the heartbeat.

   pluginname

     Specifies the name of the heartbeat plug-in.

   `-p` propertysetting

     Specifies a heartbeat plug-in property that is assigned a value by using a name=statement pair. Multiple properties might be set at one time by using multiple statements.

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

     Note - You cannot edit some properties of the default plug-ins.

   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 `geohb` command, refer to the `geohb`(1M) man page.

Example 6-3 Modifying the Properties of the Heartbeat Plug-in

This example modifies the settings of the default TCP/UDP plug-in, `tcp_udp_plugin`, to use only TCP.

    # geohb modify-plugin -p Plugin_properties=paris-cluster/TCP/2084 \
    tcp_udp_plugin hb_cluster-paris~cluster-newyork
