Changing The Primary Cluster Server; Applying Changes To Cluster Members - Novell ACCESS MANAGER 3.1 SP1 - GATEWAY GUIDE Manual

6.4.2 Changing the Primary Cluster Server

If the current primary cluster server is down and will be down for an extended period of time, you
should select another server to be the primary cluster server
1 In the Administration Console, click Devices > Access Gateways > [Name of Cluster] > Edit.
2 In the Primary Server drop-down list, select the name of a server, then click OK.
Please be patient. Wait until this configuration change has completed, before doing any other
configuration updates.
3 To update the Identity Server, click Identity Servers > Update.

6.4.3 Applying Changes to Cluster Members

When you are configuring services of the Access Gateway, the OK button saves the change to
browser cache except on the Configuration page. The Configuration page (Devices > Access
Gateways > Edit) provides a summary of the changes you have made. The Cancel Change column
allows you to cancel changes to individual services. When you click OK, the changes are saved to
the configuration datastore and you no longer have the option to cancel changes to individual
services.
When servers are in a cluster, you might want to update only one server in the cluster and verify that
the changes are behaving as expected. If this is your plan, we highly recommend that you save the
proposed changes to the configuration datastore so the changes are not lost. If your session times out
or you log out, any configuration changes that are saved to browser cache are flushed. These
changes cannot be applied to other members of the cluster because they are no longer available. To
prevent this from happening, save the changes to the configuration datastore.
After testing the configuration on one server, you can then apply the saved changes to the other
servers in the cluster, either individually (with the Update link) or as group (with the Update All
link).
If you discover that the configuration change is not behaving the way you want it to, you can revert
back to the previous applied configuration by doing the following:
1 Remove the server that you have applied the configuration changes from the cluster.
2 Access the Configuration page for the cluster, then click Revert.
The servers in the cluster revert to the last applied configuration.
