Remove the arbitration service

If you no longer need the arbitration service, you can remove it from the cluster.

Prerequisites

The arbitration service is disabled for all tenants. Otherwise, an error will be reported when you remove the arbitration service. For more information, see Disable the arbitration service.

Procedure

1. Log on to the sys tenant of the cluster as the root user.

   Note that you must specify the corresponding fields in the following sample code based on your actual database configurations.

   obclient -h10.xx.xx.xx -P2883 -uroot@sys -p***** -A
   

   For more information about how to connect to a database, see Database connection overview (MySQL mode) or Database connection overview (Oracle mode).

2. Execute the following statement to remove the arbitration service:

   ALTER SYSTEM REMOVE ARBITRATION SERVICE 'arb_server_ip:arb_server_port';
   

   Parameters:

   • arb_server_ip: the IP address of the server from which the arbitration service is removed.

   • arb_server_port: the remote procedure call (RPC) port for the arbitration service to be removed. By default, Port 2882 is used.

   Sample statement:

   obclient [(none)]> ALTER SYSTEM REMOVE ARBITRATION SERVICE '100.xx.xx.xx:2882';
   Query OK, 0 rows affected
   

What to do next

If you want to use the arbitration service after you remove it, you must redeploy the arbitration service.
