27.4 Changing the Backup Registry Host

You can change the backup host as part of a rgy_switchover operation or without changing the primary registry host.

Changing Backup Registry Host Using rgy_switchover

You are promoting the current backup registry host to primary host, as described in Moving the Registry to an Active Backup Registry Host. In this case, the -backup argument to rgy_switchover specifies the new backup registry host. In addition, rgy_switchover updates all reachable clients to recognize the new configuration.

Changing Backup Registry Host Without rgy_switchover

You are changing the backup registry host, without changing the primary registry host with rgy_switchover. The following procedure makes host rgy3 the backup registry host while leaving rgy1 the primary registry host:

1. Log on as the privileged user on each ClearCase host.

2. Stop ClearCase.

3. Reconfigure the host to use rgy3 as the backup registry host. On UNIX, open /var/adm/atria/rgy/rgy_hosts.conf and change its second line to rgy3. On Windows, use the Registry tab of the ClearCase program in Control Panel. Enter rgy3 in the Backup registry host box. Click OK or Apply.

4. Restart ClearCase.
