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

• To avoid data loss, during DB2 HADR configuration, the peer window value must be
appropriately set. This value must be four times the multiple of the value of monitor interval.
This is to ensure that the role takeover is initiated within peer window time. Use Network Time
Protocol to ensure time synchronization between the nodes where the primary and standby
database resides.
• If the DB2 HADR toolkit packages are configured in multiple subnet environment, use alias
names for Interconnect traffic IP and to configure DB2 HADR. When multiple IP entries are
created for an alias name in the /etc/hosts file, it enables the package to transition to
different subnets.
NOTE:
◦ You must configure the client application connect IP as DB2 HADR package IP.
◦ All IP addresses used in the DB2 HADR package must be in the LAN that is monitored
by Serviceguard.
IMPORTANT: HP recommends that you do not run any DB2 or HADR commands manually,
when DB2 HADR packages are up and running because these operations may interfere with
the way that Serviceguard controls DB2 HADR. Therefore, the results might be inconsistent.
