HLLAPI is a standard API for automating terminal tasks. A HLLAPI trace displays the HLLAPI calls the application is making, including return codes. You can use the trace for troubleshooting problems with a HLLAPI application and send the generated file to customer support.
To create a HLLAPI trace
In the Reflection Workspace Settings dialog box, select Configure Workspace Attributes. Then select Enable HLLAPI logging and specify a HLLAPI log file name in a location where you have the appropriate permissions to create and save a file.
In the Reflection Workspace, open or create a session document to connect to your IBM host, and start the HLLAPI application. Perform the actions you want to record in the trace.
Close the HLLAPI application.
The trace file is automatically saved as hllapi.log in the folder selected in the HLLAPI log file box.
