To debug problems associated with the internal operation of the Licensed Internal Code, use the Trace Internal (TRCINT) command to collect data.
This function is typically used at the request of your service provider.
The Trace Internal (TRCINT) command is used to collect data about the internal operation of the Licensed Internal Code. Use TRCINT to debug a problem that you can re-create, but is not visible at the application level. For example, you can use TRCINT to debug Licensed Internal Code in the TCP/IP protocol stack and sockets.
To use the CL commands to perform the internal trace, have *SERVICE special authority, or be authorized to the service trace function of i5/OS® through iSeries™ Navigator. See the chapter on user profiles in iSeries Security Reference for more information about this type of authority.
