Before you can deploy a mediation module onto a server or server
cluster, you must have configured that server or cluster for the SCA runtime
required. This advanced configuration defines whether queue destinations exploited
by the SCA runtime are hosted locally or on a remote 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.
- 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.
For more
information about creating servers or server clusters, see the following task
descriptions:
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.
To
specify where the queue destinations are created, you complete one of the
following configuration alternatives for the server or cluster.
Alternatives for this task
- Set the advanced configuration of the server or cluster to host
destinations. The configuration defines that this server or cluster
can host queue destinations for mediation modules deployed locally or for
mediation modules deployed on other servers or clusters. This configuration
also adds the server or cluster as a member of the SCA.SYSTEM bus, and configures
the messaging engine for the server or cluster.
To perform this configuration
task, see Configuring a server or cluster to host queue destinations for mediation modules.
- Set the advanced configuration of the server or cluster to use
remote destinations. The configuration defines that this server
or cluster uses a remote destination location for destinations.
This
server or cluster does not need to be a member of the SCA.SYSTEM bus.
If
you deploy a mediation module to this server or cluster, the queue destinations
are configured on a different server or cluster that is a member of the SCA.SYSTEM
bus.
To perform this configuration task, see Configuring a server or cluster to use remote destinations for mediation modules.
Result
The server or cluster is configured to accept the deployment of mediation
modules.
What to do next
You can now deploy mediations onto the server or cluster or take
other actions to manage the server or cluster.
