NNL-00008
request not understood by server
Cause
The control program issued a request to an Oracle Names server and the server did not understand the request.
Action
If the server and the control program have different versions, they may be unable to communicate. Check your documentation for version compatibility constraints. If the server and control program are compatible, turn on tracing for further details, and re-execute the failing operation. If the error persists, contact Worldwide Customer Support.
