The online tester can online test test-only UAPs such as SUP, SPP, and MHP by interlocking with the debugger. This facility is called debugger interlocking.

Specify debugger interlocking for each UAP in the user service definition and execute the online tester command. The main function in the UAP activates the debugger. Interlocking the debugger easily provides step-by-step debugging or batch debugging.

The available debugger is:

• dbx
• cbltd (COBOL85/TD)
• cblcv (COBOL85/TD)

Before testing a UAP online by interlocking the debugger, test that UAP is offline. Do not let more than one user interlock the debugger on the same node to perform a test. This is a guard against an effect on the OpenTP1 system when the UAP interlocked to the debugger terminates abnormally.

The user can collect trace information about a UAP interacting with the debugger in the same manner as a UAP that operates independently of the debugger. However, part or all of the trace information may be unavailable depending on the timing when the online tester writes trace information. Figure 2-13 outlines how debugger interlocking works.
