Oracle API Gateway - Version and later
Information in this document applies to any platform.


After following all the steps to upgrade OAG to, it was necessary to make some changes to the environment to reflect some customized settings in the original environment. After restarting nodemanager, the following error is seen in the console:

ERROR warning: failed to load crypto provider
ERROR warning: failed to load crypto provider

java.lang.NoClassDefFoundError: com/vordel/jce/JCEProvider
  at com.vordel.dwe.Service.(

  at Method)

 An upgrade from an earlier version was performed, and once this was completed, the system jvm.xml file was copied form the old version to the new one so that the custom settings added to that file originally would carry over to the new environment.
