Configuration item COMMS_FACILITY_TRACE allows the creation, change, and deletion of LANSA Communications Extensions Facility Tracing Records. These records are used to set tracing and logging options for each facility or module. When the listener job starts, it enables the tracing options specified by these records or those specified on the listener record.
Select configuration item COMMS_FACILITY_TRACE from the COMMS_EXTENSIONS group to review Communications Facility Tracing Records. The screen presented looks something like this:
|
|---|
This screen lists all the facilities (modules) for which tracing records have been created. To the right of the facility name is a summary value of the tracing flag settings.
- Full: Means all tracing and logging options have been selected for this facility or module.
- Partial: Means that some, but not all tracing and logging options have been selected for this facility or module.
- None: Means that the facility tracing record exists, but none of the tracing or logging options have been selected.
Working from this screen you can, by entering one of the options beside a list entry, perform these actions:
2=Review/Change: Display the tracing and logging details for the facility tracing record. From the screen displayed, press the Change function key to enable the fields to be amended.
4=Delete: Delete the facility tracing record on which this option is entered.
Pressing the Add/Create function key will present the Add Facility Tracing screen which allows the addition of a new facility tracing record.

These input options are required on the Add Facility Tracing Record screen:
Facility (Module)
The facility or module for which the tracing and logging options are specified. It must be one of these values:
- CPIC MANAGER: The CPIC Manager service program.
- IPC MODULES: The Inter Process Communications (IPC) module. For example, the TCP/IP sockets module.
- LISTENER: The listener program.
- TP STUB: The Transaction Program (TP) entry program.
- ADMIN UTILITY: The LANSA Communications Extensions program to maintain configuration items.
Tracing Options
Check (enter any non-blank character) beside the events or actions which require tracing:
Errors | Traces error information. This consists of errors which may be considered "normal" during communications as well as any "fatal" errors encountered. "Fatal" error messages are also written to the IBM i job log. |
System Info | Traces basic information at the system software level such as version negotiation. |
Debug Listener | Traces the events in the listener job. |
CPIC Data | Trace data sent and received at the point where LANSA Communications Extensions APIs are called. |
IPC Data | Trace data sent and received at the point where the Inter Process Communications (IPC) interface (for example, TCP/IP sockets) is called. |
External IPC Calls | Trace calls to the IBM i communications interface (for example, TCP/IP sockets APIs). |
Internal IPC Calls | Trace calls made to the Inter Process Communications (IPC) interface (for example, the Sockets IPC Module). |
Calls to CPIC | Trace API (CPIC) calls to the LANSA Communications Extensions CPIC Manager. |
Cryptographic Info | Trace cryptographic information |
Logging Options
Enables the recording of normal events which need tracking. On the IBM i, messages are sent to the job's external message queue and will be listed in the job log. Check (enter any non-blank character) beside the event(s) which require logging:
Connect In | Record details of incoming connection requests. |
Connect Out | Reserved for future use. |
