Debugging Your Application

Two types of traces are provided to help troubleshoot problems with your application:

·         Data Stream Trace
This trace captures the TN3270 or TN5250 data stream that is transmitted between the host and PASSPORT Host Integration Objects. This type of trace is very helpful in resolving problems involving the SNA BIND attributes as well as other problems involving the data stream.

·        Low Level Trace
This trace captures the lowest level of communication between the PASSPORT Host Integration Objects communications driver and the underlying communications subsystem. This type of trace is very helpful in resolving problems involving the establishment of a connection.

These traces are enabled by calling the EnableTrace method of the Session object. The trace files that are generated when the trace flags are enabled are stored in the folder where the Resource Configuration File (.ZCC) is stored. These are text files that are named as follows:

Trace	File Name
Data Stream	ResourceConfiguration__SessionID_ds.txt
Low Level	ResourceConfiguration__SessionID_ll.txt
Where ResourceConfiguration is the name of the configuration file used to start the session and SessionID is a unique ID assigned to the session.
