Configuring a data source for a messaging engine running in a cluster

Methods that you can use to configure a data source for a messaging engine depend on the cluster in which you intend to run the messaging engine.

About this task

Although you must configure a data source for all active messaging engines, the configuration process for a messaging engine running in a cluster is the same as for any single messaging engine. For more information, see Creating the database, schema and user ID for a messaging engine and Data source minimum required settings, by vendor.
The data store configuration depends on the purpose of your cluster:
  • For a workload managed (WLM) cluster, every messaging engine in the cluster must have its own unique data store schema.
  • For a failover (HA) cluster, you must have only one data store schema that will be used by the active messaging engine wherever it starts.

For more information about clusters, see Service integration high availability and workload sharing configurations.

When a messaging engine is created as a member of a cluster, you must explicitly configure both the data store and the JDBC data source that the messaging engine uses to interact with the data store.
  • If each messaging engine has its own JDBC data source, you can create the data sources at node scope.
  • If several messaging engines share the same JDBC data source, you must create the data source at cluster scope, not node scope.

You must also ensure that you install the JDBC driver jars at every node. For more information, see Configuring a data source using the administrative console.
