HP Serviceguard Toolkits for Database Replication Solutions User Guide, March 2012

Figure 14 HA to Primary Database
This configuration provides High Availability (HA) to primary databases. In Figure 14 (page 39),
DB2 primary database is configured in a volume group shared between Node1 and Node2 in a
Serviceguard cluster. The standby database is running on Node3 placed outside the cluster. The
primary package is configured to run either on Node1 or Node2 and running on Node1. The
standby database is not packaged using DB2 HADR toolkit.
This configuration does not provide the role management feature for DB2 HADR toolkit. Thus, the
package does not handle automatic role takeover or role switch. HA to primary database is
provided through failover. If primary database fails on Node1, Serviceguard brings up the primary
database on Node2. The client node cannot connect to the database until it comes up on Node2.
In this configuration, set the ROLE_MANAGEMENT attribute to [no].
