- If
you are upgrading from a DB2 Version 9.8 Fix Pack 4 pureScale environment
or earlier, the value of hadr_remote_host is
set to the value on member 0.
The information that is referenced by the
hadr_remote_host configuration
parameter is dependant on what role the server or cluster is assigned.
- On a primary, this configuration parameter references the host
of the principal standby. In a DB2® pureScale® environment,
it contains a pipe-delimited (|) list of all addresses
(hosts and ports) in the standby cluster.
- On a standby, this configuration parameter references the host
of the primary. In a DB2 pureScale environment,
it contains a pipe-delimited (|) list of all addresses
(hosts and ports) in the primary cluster.
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.
Similar
to hadr_local_host, this parameter must map to
only one IP address.
