Use these steps to define a data source on multiple nodes that comprise a cluster.

See Administrative console scope settings for more information about scope settings in general.

 

Overview

The cluster scope has precedence over the node and cell scopes. Create a JDBC provider for a cluster if you 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

 

Procedure

1. Open the console.

2. Click...

   Resources | JDBC | JDBC Providers

3. From the scope drop-down list, select the cluster for which you are creating the JDBC provider. (This scope becomes the scope of any data source that you associate with this provider.)

4. Click New. This action causes the Create a new JDBC Provider wizard to launch.

5. Complete the wizard, then click Finish.

6. Click...

   Environment | WebSphere Variables

   ...in the administrative console.

7. For each node in the cluster, select the symbolic variable used in the class path of your JDBC provider, and provide a value that is appropriate for the selected node. For example, if the class path of your JDBC provider uses the symbolic variable...

   ${DB2390_JDBC_DRIVER_PATH}

   ...you 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.

8. 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.

9. Click Apply and save the changes.

   This variable must be defined on each node within the cluster.
