Debugger Selection on TNS/E Systems
Debugger Selection on TNS/E Systems
Debugger selection is determined by the debugging attributes of a process. The rules
for debugger selection differ according to system type (TNS/R or TNS/E). The rules
followed on a TNS/R system are different from the rules on a TNS/E system. In
addition, the TNS/R system debugger is Debug, but the system debugger on TNS/E
systems is Native Inspect.
When a debugger is invoked on a TNS/E system, the system software selects the
debugger according to the rules of precedence described in Table 18-1.
Considerations About Debugger Selection

Visual Inspect can only be selected when you have already established a matching
Visual Inspect client connection.

If the Inspect subsystem is not able to find a suitable debugger (either Visual
Inspect or Inspect), the debugger selected is the TNS/E system debugger, Native
Inspect, which is not part of the Inspect subsystem.

Native Inspect has extremely limited support for debugging TNS processes.
Therefore, Inspect is the preferred debugger for TNS processes even if INSPECT
is set to OFF.

COBOL programs on a TNS/E system must be debugged using either:

Inspect for TNS COBOL85 programs

Visual Inspect for either TNS COBOL85 or TNS/E COBOL programs
Table 18-1
illustrates that on a TNS/E system, Inspect is invoked as the chosen
debugger to debug a TNS emulated process in only two cases -- when the INSPECT
attribute is ON and Visual Inspect is not available, or when INSPECT is OFF (also see
Figure 18-2 on page 18-6).
For background information about the debugging attributes of a process, see The
Debugging Attributes of a Process on page 4-4.
