HiRDB Datareplicator Version 8 Description, User's Guide and Operator's Guide
Datareplicator can achieve system switchover by using HiRDB's system switchover facility. This facility swaps Datareplicator systems when HiRDB systems are swapped. You cannot swap only the Datareplicator systems as the response to a Datareplicator error. For details about handling of the system switchover facility in HiRDB, see the HiRDB Version 9 System Operation Guide.
The cluster software programs shown in the following table support the system switchover facility.
