- Upgrade Note
- If you are upgrading from a Db2® Version 9.8 Fix Pack 4 pureScale environment or earlier, the value of hadr_remote_inst is set to the value on member 0.
The information that is referenced
by the hadr_remote_inst configuration parameter
is dependant on what role the server or cluster is assigned.
- On a primary, this configuration parameter references the instance name of the principal standby.
- On a standby, this configuration parameter references the instance name of the primary.
Unless you are using the Db2 pureScale® feature, this parameter must have a non-NULL value in order to set up HADR. This parameter is under automatic configuration when the hadr_target_list configuration parameter is set, but you should still ensure that it has the correct value in case the integrated cluster manager, IBM® Tivoli® System Automation for Multiplatforms (SA MP), picks up the incorrect value before it is automatically reconfigured.
1 Changes
to this parameter take effect on database activation. If the database
is already online, you can have changes take effect by stopping and
restarting HADR on the primary database.
