Unknown error when using Opatch
Hello! We encountered a problem when updating the Weblogic service using the OPath utility. OS version Centos 6, JAVA version 1.8.0_66, Weblogic version 12.1.3. The server already had Weblogic installed, how the service was installed is not known, there was no OPath utility, I installed OPath version 13.2.0.0.0 separately, when entering simple commands such as ./opatch help an error appears:
«Exception in thread "main" java.lang.NoClassDefFoundError: com/oracle/cie/gdr/external/InventoryException
