Copy the driver to all application servers.

Set the environment variable at the node level to the driver’s path.

C.

Create a JDBC provider in the node scope and the data source in the cell scope.

Copy the driver to the deployment manager.

Set the environment variable at the server level to point to the deployment manager path.

D.

Create a JDBC provider in the application scope and the data source in the server scope.

Copy the driver to all application server directories.

Set the environment variable in each JVM to the driver’s path.

Question 2
