Resolution

Within the Interchange/logs/<Hostname>_cn_classpath.log verify if any custom classes are loaded into the CN classpath through the following locations:

<Shared>/local_te/classes

<Shared>/local_te/conf

<Shared>/local_te/jars

<Install>/Interchange/corelib

<Install>/Interchange/site/jars

Some custom added jars such as activemq-all-5.14.5.jar could lead to conflicts with the Oracle UCP drivers. Either these jars should be removed or a less conflicting jar must be obtained.
