You can change the messaging engine policy for a messaging engine
in a cluster so that it conforms to one of the predefined messaging engine
policy types that are available when you use messaging engine policy assistance.
About this task
Use this procedure when you are creating or maintaining a cluster
bus member and messaging engine policy assistance is enabled, but there are
warning messages that the messaging engine policy should be corrected. For
example, you create and configure a cluster for scalability, where each messaging
engine cannot fail over. If you want to change the cluster to provide scalability
and high availability, the messaging engine policies must be corrected so
that the messaging engines can fail over, and the preferred servers list must
be corrected so that there is a preferred server and a failover server for
each messaging engine.
This procedure does not add or remove messaging
engines. If there are warning messages to add or remove messaging engines
to conform to the selected messaging engine policy type, use
the procedures in the related tasks.
Procedure
- In the navigation pane, click .
If messaging engine policy assistance is enabled, the Bus member
detail panel is displayed. If messaging engine policy assistance is not enabled,
the messaging engine collection panel is displayed.
- If messaging engine policy assistance is not enabled, click Enable
policy assistance and follow the instructions on the wizard.
- From the Bus member detail panel, in the content pane, under Additional
properties, click Messaging engine policy maintenance.
A list of messaging engines for the cluster, and details of their
current messaging engine policy settings, is displayed. Messages in the details
column indicate whether the current settings conform to the selected messaging
engine policy type.
- Select the policies you want to correct, then click Correct
messaging engine policy.
- Save your changes to the master configuration.
Results
The selected messaging engine policies are corrected and the new policy
settings are displayed in the panel. The core group policies and match criteria
for the messaging engines are automatically corrected.
