A. Description

The rgy_switchover command upgrades a backup registry server host (see rgy_backup) to primary registry server host and resets ClearCase clients to use the new primary registry server host. rgy_switchover logs its activities to /var/adm/rational/clearcase/log/albd_log (UNIX) or the Windows event log.

rgy_switchover can modify configuration information only on hosts that are running ClearCase. This means that if the failure of a primary registry server causes a switchover, the (former) primary registry server cannot be informed of the switchover.

To reinitialize the tag registry password

Because rgy_backup does not copy the tag registry password file to a backup registry, you must initialize the tag registry password with the rgy_passwd command after you run rgy_switchover.

Options and arguments

B.  Specifying the new backup registry server

Default

None.

–backup new-backup-server

Configures new-backup-server as the backup registry server host, after switching the current backup registry server host to the primary registry server host.

C. Specifying a time stamp

Default

rgy_switchover uses the most recent registry backup files in the new-primary-rgy-host's backup directory.

–time file-timestamp

Activates an alternate set of backup registry files. The file-timestamp much match an existing set of time-stamped files in backup. By default, the ClearCase scheduler runs rgy_backup periodically and deletes backed-up registry files more than three days old.

D.  Specifying the old and new primary registry servers

Default

None. You must specify the current and target primary registry server hosts.

old-rgy-host

The current primary registry server host.

new-rgy-host

The current backup registry server host that will become the new primary registry server host.
