You can remove a messaging engine from a cluster so servers that
are members of the cluster cannot send and receive messages.
Why and when to perform this task
To remove a messaging engine from a cluster:
Steps for this task
- In the navigation pane, click .
- In the content pane, click the name of the bus.
- In the content pane, under Additional properties, click Bus
members. A list of members in the bus is displayed.
- In the content pane, select
the cluster from which you want to remove a messaging engine. A
list of messaging engines for the server is displayed.
- In the content pane, select
the messaging engine that you want to remove.
- Click Remove messaging engine.
- Save your changes to the master configuration.
The messaging engine is removed from the cluster.
Remember: When
you remove a messaging engine, WebSphere Application Server does not delete
the data store tables automatically.
If you want to recreate the same messaging engine,
you must first delete the previous set of tables. But if you create a messaging engine with existing tables,
they must be empty, so that the messaging engine can
function correctly. Refer to the documentation for your chosen relational
database management system (RDBMS) for information about how to delete tables.
However, if you have created a data store with
default settings, you do not need to delete previous tables.
You can also use the
deleteSIBEngine command to remove a messaging
engine from a cluster.
