- 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.
