DLC Tracing

Microsoft® SNA Server provides the facility for tracing message flows at the Data Link Control (DLC), both at the local node and at the application's Base. This allows you to track the messages being sent and received by the local node and/or the SNALink.

Note The registry entries used to control tracing are inserted by the Setup program. The SNATRACE.EXE program can be used to enable or disable internal tracing dynamically at run time (assuming binaries have been compiled with internal tracing enabled).

Message tracing at the SNALink is controlled by entries in the Microsoft® Windows NT® registry under:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\...\
<SNALink name>\Parameters

Message tracing at the local node is controlled by placing similar entries under:

HKEY_LOCAL_MACHINE\System\CurrentControlSet
\Services\SNAServr\Parameters

The entries required in both cases are as follows:

MessageTraceFile1=file1
MessageTraceFile2=file2
DLCTraceState=on (or off)
