With a specific version of WAS ND, i.e., and the connection to a Oracle repository seems to always fail with Connection Not Available or something similar to this. If you are using an enterprise application you might see the "Attempt to start the Enterprise bean#bean id failed with an exception" and the cause might be a "java.lang.AbstractMethodError: java/sql/Wrapper.isWrapperFor(Ljava/lang/Class;)Z"

This is a known issue with the specific versions of WAS and APARs have been created to address the same. You can find the problem report and resolution summary in the below links
