In the JNDI Name field, specify a unique name for the XA JDBC resource. By convention, the name begins with the jdbc/ string. For example:
jdbc/iepseOracleXA
You use the JNDI name in a later procedure.
In the Pool Name drop-down menu, select the XA connection pool that you created.
Click OK.
The JDBC resource is created.
