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 .
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:
- In the list of components, click Messaging Engine. The status for the service integration bus and the messaging
engine is displayed.
- To launch the configuration wizard, click Configure
the Messaging Engine.
- 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.
- 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.
- 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.
- 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.
- Return to the configuration page by clicking IBM Business Monitor configuration in
the breadcrumb listing.
