ODBC Trace Log

[TheBigA]

I have an issue where I am using a vendor products out-of-the-box configuration tool to connect to an Oracle 11g database. There are two options for connecting; use tnsnames reference directly or use an ODBC. Because I am having issues I decided to use an ODBC data source and turn on tracing. It produced some good information, but I am trying to get a better understanding of the information in the Microsoft ODBC Trace log (SQL.LOG by default). Is there anything available that explains the information contained in that trace file? Specifically there is a line that looks like it is showing the Oracle schema starting with "PTR" - what is this telling me? Below is a snippet from the trace log. Can anyone tell me what this means? Or is there some good reference material on interpreting the trace file?

Thank you!
