You can use two mechanisms for maintaining user
profiles on all nodes within a cluster.
One mechanism is to create a cluster administrative domain
to monitor shared resources across nodes in a cluster. A cluster administrative
domain can monitor several types of resources in addition to user profiles,
providing easy management of resources that are shared across nodes. See Monitored resources for
details on these resources. When user profiles are updated, changes are propagated
automatically to other nodes if the cluster administration domain is active.
If the cluster administrative domain is not active, the changes will be propagated
once the cluster administrative domain is activated. Note: If you plan to
share user profiles that use password synchronization within a cluster, you
must set the Retain Server Security (QRETSVRSEC) system value to 1.
With the second mechanism, administrators can
also use Management Central in iSeries™ Navigator to perform functions
across multiple systems and groups of systems. This support includes some
common user-administration tasks that operators need to perform across the
multiple systems in their cluster. Management Central allows user profile
functions to be performed against groups of systems. The administrator can
specify a post-propagation command to be run on the target systems when creating
a user profile.
