Configuring the IBM Business Monitor messaging engine

The messaging engine is required for IBM® Business Monitor. In the four-cluster topology, the messaging engine is installed on the messaging engine cluster.

About this task

To view this administrative console page, click Servers > IBM Business Monitor configuration.

IBM Business Monitor requires its own service integration bus and messaging engine, even if you plan to use the table-based or scalable method to monitor events. A service integration bus is a group of one or more application servers or server clusters in a cell that cooperate to provide asynchronous messaging services. The application servers or server clusters in a bus are known as bus members. The server component that enables a bus to send and receive messages is a messaging engine. The messaging engine provides a connection point that applications use to connect to the bus.

If you do not have an existing bus, one is created for you when you configure the messaging engine. The bus is named MONITOR.<cell_name>.Bus and the name cannot be changed.

Procedure

To configure the messaging engine, complete the following steps:

  1. In the list of components, click Messaging Engine. The status for the service integration bus and the messaging engine is displayed.
  2. To launch the configuration wizard, click Configure the Messaging Engine.
  3. On the Select a bus member panel, choose one of the following options to select the location where the messaging engine will be created:
    • Cluster: Choose this option to create the messaging engine on an existing cluster. You must select the cluster name from the list.
    • Server: Choose this option to create the messaging engine on a server. You must select the server from the list. If you have more than one server with the same name, be sure to choose the server on the correct node.
    Click Next.
  4. On the Select the type of message store panel, choose one of the following options:
    • Data store: A data store is a message store that contains a set of tables that are accessible to all members of the cluster that hosts the messaging engine.
    • File store: A file store is a message store that uses files in a file system through the operating system. This option is not available if you chose Cluster on the Select a bus member panel.
    Click Next.
  5. If you are using a data store, choose one of the following options on the Provide the message store properties panel:
    • Create a default data source with generated JNDI name: By default, the data store uses Derby. This option is not available if you selected Cluster on the Select a bus member panel.
    • Use an existing data source: If you select this option, complete the following fields:
      • Data source JNDI name: Select the JNDI name that corresponds to the database that you are planning to use.
      • Schema name: Enter the schema name.
      • Authentication alias: Select the authentication alias that you are planning to use. You must select the authentication alias if you want the tables to be created.
      • Create tables: Select this option to create the tables in the database. If you do not select this option, the database administrator must create the tables.
    Click Next.
  6. On the Confirm panel, review the information.
    • If all information is correct, click Finish.
    • To change information, click Previous to return to the information that you want to change.
    When you click Finish, the status boxes for the bus and messaging engine are updated with the new configuration information.
  7. Return to the configuration page by clicking IBM Business Monitor configuration in the breadcrumb listing.
