Adding additional messaging engines to a cluster bus member

You can add extra messaging engines to a cluster bus member, for example to provide high availability or scalability in a cluster.

About this task

When you add a server or cluster as a member of a bus, at least one messaging engine is created automatically. Each server bus member has only one messaging engine. However, cluster bus members can support additional messaging engines.

You can add multiple messaging engines at the time you create the cluster bus member, or you can add extra messaging engines at a later time.

When you add an extra messaging engine to an existing cluster bus member, the flow of messages through existing messaging engines is not disrupted. Also, if dynamic reloading is enabled (by selecting the Configuration reload enabled property for the cluster bus member), the existing messaging engines do not have to be restarted to become aware of the new messaging engine.

For more information about configuring bus properties, see Configuring bus properties.

Procedure

  1. Add an extra messaging engine to an existing cluster bus member by completing one of the following steps:
    • Add one or more messaging engines when you create a new cluster bus member. Use messaging engine policy assistance, which guides you through the creation and configuration of the messaging engines. See 新增叢集作為匯流排的成員.
    • Add an extra messaging engine to an existing cluster bus member. Either use the administrative console as described in 將傳訊引擎新增至叢集中, or use the createSIBEngine command.
  2. Optional: Enable dynamic reloading for the cluster bus member:
    1. In the administrative console, navigate to 伺服器 -> 伺服器類型 -> WebSphere Application Server -> server_name -> [伺服器傳訊] SIB 服務.
    2. Select Configuration reload enabled.
    3. Click OK.
  3. 儲存對主要配置所做的變更。
