Using match criteria to associate a policy with a messaging engine

Use this task to configure match criteria to associate a policy with a messaging engine.

Before you begin

To complete this task you must have created a policy to associate with the messaging engine.

Why and when to perform this task

Each messaging engine is managed by an HAGroup to which a policy is assigned at runtime. The policy assigned to an HAGroup is chosen by comparing the match criteria of the set of configured policies with the properties of the HAGroup. The policy with the strongest match is assigned to the HAGroup. The table below lists the names and values of the HAGroup properties for a messaging engine, and the set of matching messaging engines if a property is used in the policy match criteria:
Name Value The messaging engine or engines that the policy will match
type WSAF_SIB Any messaging engine
WSAF_SIB_MESSAGING_ENGINE The name of your messaging engine. This will be in the form node.server-bus for a messaging engine in a server, or cluster.number-bus for a messaging engine in a cluster, where number relates to the order that messaging engines were added to the bus (the messaging engine that is created automatically when you add the cluster to a bus has the number 000). A particular messaging engine
WSAF_SIB_BUS The name of your bus All messaging engines in a particular bus
IBM_hc The name of your cluster All messaging engines in a particular cluster
For more information about match criteria for messaging engines, see Match criteria for service integration.

Steps for this task

  1. If not already open, open the policy page by clicking Servers > Core groups > Core group settings > core_group_name [Content pane] > Configuration > Policies [Additional Properties] > policy_name [Content pane].
  2. Create a new match criterion by clicking Match criteria [Additional Properties] > New.

    The Name and Value fields together specify a messaging engine or group of messaging engines that will be linked to this policy. Use the information in the table above to find the required name and value for the selection you want.

    For more description of the fields on this page, see Match criteria settings. For more information about finding the correct names for match criteria, see Core group settings

  3. You can add more criteria to progressively restrict the set of HAGroups that the policy could match. For example you could specify all the messaging engines that are both on a particular bus and in a particular cluster by using the relevant pair of criteria.
