On z/OS®, you can debug load
modules that run on MVS™,
including load modules that run in a subsystem (CICS® or IMS™).
Debugging can occur only if a debug daemon is listening.
- In the z/OS Projects view,
right-click the executable and select Debug Application.
The debug daemon is started automatically.
- If you want to start an application outside of Developer for System z® (by running a CICS transaction from a 3270 emulator,
for example), verify that the daemon is running before attempting
to debug the application:
- Switch to the Debug perspective. Click Window > Open
Perspective > Other , and then select Debug.
- Hover over the icons in the Debug view; if a hover help says "Debug
UI daemon is listening on port: portnumber. Click
to stop listening," the daemon is running, but if a hover help says
"Debug UI daemon is not listening. Click to start listening on port: portnumber,"
start the daemon by clicking the related icon. The icon for the listener
is disabled when it is listening (that is, when the daemon is running).
