For mediation modules, a cluster or server can be configured so
that the queue destinations are created on a different server or cluster.
Before you begin
Before starting this task, you must have already created one or more
servers or server clusters required:
- The server or cluster on which you want to deploy mediation modules. This
is the server or cluster to be configured in this task.
- The server or cluster on which you want to create queue destinations for
the SCA runtime to exploit.
You can use the same server or cluster in both cases.
Why and when to perform this task
When you install a mediation module into WebSphere ESB,
a number of queue destinations are created for components of the mediation
module that use asynchronous interactions. The queue destinations are used
by the SCA runtime to hold messages being processed for the mediation module.
You
can configure your servers and clusters so that the queue destinations are
created on the server or server cluster that the mediation module is deployed
to, or on a different server or cluster.
A
server or cluster that does not host the queue destinations for mediation
modules can be optimized to run other components, and does not have to be
a member of the SCA.SYSTEM bus.
This configuration task defines that
the server or cluster uses queue destinations created on a different server
or cluster. This configuration does not add the server or cluster as a member
of the SCA.SYSTEM bus
To configure a server or cluster to use queue
destinations created on a different server or cluster, use the administrative
console to complete the following steps:
Steps for this task
- Display the Advanced Configuration page for
the server or cluster.
- To configure a server:
- To configure a cluster:
- Verify the value in the Emitter Factory Profile JNDI Name field.
- If you want to change the default configuration for emitting events
to the CEI server, select the appropriate emitter factory profile JNDI name
from the field. In a clustered environment, the value you select is used for
all servers in the cluster.
- If you do not want to specify an emitter factory profile (thus preserving
an existing CEI configuration), select None from the
menu.
- Clear the Do not configure to host Process Server applications option.
- Configure the Remote Destination Location option
for the server or cluster:
- Click Remote Destination Location.
- Use the associated menu to select the name of the
remote server or cluster that hosts queue destinations for mediation modules.
- Click OK.
- Save your changes to the master configuration.
What to do next
If you deploy a mediation module to this server or cluster, the queue
destinations for the mediation module are configured on the server or cluster
specified by the
Remote Destination Location property.
You
can change the configuration of the server or cluster, add it as a member
of a service integration bus, or
take other actions to manage the server or cluster.
