Configure a data source for a messaging engine running in a cluster
Methods that we can use to configure a data source for a messaging engine depend on the cluster in which you intend to run the messaging engine. Although 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.
See Create 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, have only one data store schema that will be used by the active messaging engine wherever it starts.
See about clusters, see Service integration high availability and workload sharing configurations. .
- If each messaging engine has its own JDBC data source, we can create the data sources at node scope.
- If several messaging engines share the same JDBC data source, create the data source at cluster scope, not node scope.
You must also ensure that you install the JDBC driver jars at every node.
