Oracle internals, debugging and undocumented features

Examining Oracle Net Trace Files

I lost a count how many times I had to trace sqlnet clients and collect trace files .Many times I tried to read them and understand what is realy going on,  but these files are hard to read and understand without detail explanation of Oracle Net protocol.Ultimatelly Oracle support will analyze them and send explanation.

Oracle white paper Examining Oracle Net Trace Files  that I have found on metalink explains connection process to the database and “decrypt ”  trace codes.Here is link:

    So, could you send me the metalink note ID?

    Thank you very much!
