Configure a JDBC provider for a clustered environment
Use these steps to define a data source on multiple nodes that comprise a cluster.
The cluster scope has precedence over the node and cell scopes. Create a JDBC provider for a cluster if we want the associated data source to:
- Be available for all the members of this cluster to use
- Override any resource factories that have the same JNDI name that is defined within the cell scope
Tasks
- Open the administrative console.
- Click Resources > JDBC > JDBC Providers.
- From the scope drop-down list, select the cluster for which we are creating the JDBC provider.
- Click New.
This action causes the Create a new JDBC Provider wizard to launch.
- Complete the wizard, then click Finish.
- Click Environment > WebSphere Variables in the administrative console.
- For each node in the cluster, select the symbolic variable used in the class path of our JDBC provider, and provide a value that is appropriate for the selected node. For example, if the class path of the JDBC provider uses the symbolic variable ${DB2390_JDBC_DRIVER_PATH}, we might supply the value /usr/lpp/db2 on one node and /usr/lpp/db2710 on another node, depending on where your DB2 390 installation is located.
- Click DB2_JDBC_DRIVER_PATH (this already exists by default). Here provide the path (in the value field) where db2java.zip exists on the selected node.
- Click Apply and save the changes.
This variable must be defined on each node within the cluster.
