Message Oracle NNL-00019 - warning: server either changed or ignored your request

ERRORwarning: server either changed or ignored your request
CAUSEThe user issued a request to an Oracle Names server and that request was altered in some way. Typically the user specified an invalid argument of some sort, and the server either ignored the request, or replaced the invalid argument with a reasonable default.
ACTIONUse the control program to check the current state of the value that you attempted to change. The servers log file may also contain information about the exact cause of the problem. Re-issue the operation with correct arguments.
