Adding a cluster to a bus with a custom configuration

You can add a cluster as a member of a bus and use messaging engine policy assistance and the custom messaging engine policy. In this situation, messaging engine policy assistance helps you to create and configure messaging engines in a cluster that is a member of a bus when the predefined messaging engine policy types do not meet your needs. You can configure the messaging engine behavior, and the appropriate messaging engine policies are created automatically.

Before you begin

Ensure that you have defined the resources listed in 新增叢集作為匯流排的成員.

About this task

When you use the custom messaging engine policy, you can create any number of messaging engines for the cluster. For each messaging engine, you must specify the behavior that you require, such as whether it can fail over and whether it uses preferred servers. The core group policies and match criteria for each messaging engine are automatically created. Use this option when the other options of High availability, Scalability, or Scalability with high availability do not provide the messaging engine behavior you require, and you are familiar with creating messaging engines and configuring messaging engine policy settings.

[AIX Solaris HP-UX Linux Windows][IBM i]You can optionally tune the initial and maximum Java™ virtual machine (JVM) heap sizes. Tuning the heap sizes helps to ensure that application servers hosting one or more messaging engines are provided with an appropriate amount of memory for the message throughput you require.

如果您在混合版本的 Cell 中工作,這個產品版本所執行的服務整合匯流排只能包括下列產品版本中所執行的 WebSphere® Application Server 第 6 版匯流排成員:
  • 6.0.2((Fix Pack 23 或更新的版本)
  • 6.1.0((Fix Pack 13 或更新的版本)

如果啟用安全,且匯流排有混合版本的匯流排成員,匯流排成員會利用跨引擎鑑別別名來建立信任關係。 如果您在 WebSphere Application Server 第 6 版新增一部伺服器叢集作為匯流排成員,且它是這個層次的第一個匯流排成員,在這項作業期間,您必須選取或建立一個鑑別別名。這個動作設定跨引擎鑑別別名。

Procedure

  1. In the navigation pane, click 服務整合 -> 匯流排 -> bus_name -> [拓蹼] 匯流排成員.
  2. Click Add to start the Add a new bus member wizard.
  3. In the first pane, select Cluster, and, from the drop-down list, select the cluster that you want to make a member of the bus.
  4. In the Messaging engine policy assistance settings pane, ensure that the Enable messaging engine policy assistance check box is selected, and select Custom.
  5. Select the type of message store that you have already defined.
  6. In the Configure messaging engines pane, click Add to add and configure at least one messaging engine.
  7. In the Configure the messaging engine policy pane, use the options and the preferred servers list to set the messaging engine behavior you require. The messaging engine name is automatically generated, in the format cluster_name.nnn-bus_name.
  8. Enter details for the message store.
    • If you use a file store, specify the directory paths for the log files, the permanent file store, and the temporary file store. Do not use the default path, and ensure that you use a unique path for each messaging engine.
    • If you use a data store, specify the JNDI name of the data source that provides access to the database that holds the data store.
  9. Optional: [AIX Solaris HP-UX Linux Windows][IBM i]In the Tune performance parameters pane, you can view the current settings of the initial and maximum Java Virtual Machine (JVM) heap sizes. If you want to tune performance by changing the current settings, select the Change heap sizes check box and enter the required changes in the Proposed heap sizes fields.
  10. If security is enabled, and adding this cluster bus member creates a mixed-version bus, the wizard prompts for an authentication alias. Do one of the following:
    • Select an existing authentication alias.
    • Create a new authentication alias. Specify a unique alias name and password.
    This action sets the inter-engine authentication alias.
  11. Optional: Repeat the steps to add and configure further messaging engines for the cluster.
  12. When the Add a new bus member wizard is finished, save your changes to the master configuration.

Results

You have created a cluster bus member and at least one messaging engine, named cluster_name.nnn-bus_name. For each messaging engine, there is a core group policy named messaging_engine_name-numberPolicy. This core group policy is configured with the behavior you chose for the messaging engine policy, and is associated with the messaging engine through its match criteria.

What to do next

To see a diagram of the cluster and the messaging engine configuration you have created, click the bus member name in the Bus members collection pane.
