Creating a policy for messaging engines

You create one or more core group policies for service integration to control your messaging engine, or engines. The policies control the high availability or workload sharing behavior of those messaging engines.

Before you begin

Decide what type of policy you need to create for the configuration you require. For service integration, the following types of core group policy apply: For further information, see Policies for service integration.

About this task

A policy is a component of a core group. A core group can have a number of different policies; each policy applies to a particular high availability group (HAGroup) and determines the high availability behavior of resources in that group. For service integration, the resources that you want to control are the messaging engines. Typically, you create one policy for each messaging engine in the cluster, unless you want the messaging engines to be managed by external high availability framework.

To create a policy for a messaging engine, use the administrative console to perform the following steps:

Procedure

  1. Open the Policy page by clicking Servers > Core groups > Core group settings > [Content Pane] core_group_name > [Additional Properties] Policies.
  2. Click New.
  3. Select one of the following from the Policies list.
    Static
    A messaging engine cannot fail over in a WebSphere® Application Server cluster.
    One of N
    A messaging engine can fail over in a WebSphere Application Server cluster.
    No operation
    A messaging engine is managed by an external high availability framework such as IBM® HACMP™. This option is for use with an external high availability cluster.

    Do not select any other policy type, because they because they are not supported for the service integration bus component.

  4. Click Next.
  5. Enter a Name that is unique in the scope of the core group.
  6. Click Apply or OK.
  7. Configure the policy. See Configuring a policy for messaging engines.
  8. Save your changes to the master configuration.
