If you are using HiRDB Datareplicator, you must perform grouped system switchovers with both HiRDB and HiRDB Datareplicator. In such a case, use the group operand of HA Monitor to define HiRDB and HiRDB Datareplicator in the same server group. For details about how to define a grouped system switchover configuration, see the manual High-Availability System Monitoring Facility. For details about the operations involved in performing a system switchover when using HiRDB Datareplicator, see the HiRDB Datareplicator Version 8 Description, User's Guide and Operator's Guide.

Automatic system switchovers

When an error occurs on the running system, the system switches automatically to the standby system. No action needs to be taken by the HiRDB administrator or HiRDB Datareplicator administrator.

Planned system switchovers

You can use HA Monitor's monswap command to perform a planned system switchover in HiRDB and HiRDB Datareplicator.

When the HiRDB system is switched over

When an error occurs and the HiRDB system is switched over, forcibly terminate the running system HiRDB Datareplicator, and then switch the HiRDB Datareplicator system.

When an error occurs in HiRDB Datareplicator

If HiRDB Datareplicator independently terminates abnormally, a system switchover is not performed because HiRDB Datareplicator restarts on the running system. Note that, if HiRDB Datareplicator independently terminates abnormally, a grouped system switchover cannot be performed on either HiRDB or HiRDB Datareplicator.

If you define a grouped system switchover configuration in advance, you can use the planned system switchover functionality of HA Monitor's monswap command to perform a grouped system switchovers.
