Starting z/OS Debugger under CICS by using DTCN

If a DTCN profile exists, when a CICS® program starts, z/OS® Debugger analyzes the program's resources to see if they match a profile. If z/OS Debugger finds a match, z/OS Debugger starts a debugging session for that program. If multiple profiles exist, z/OS Debugger selects the profile with the greatest number of resources that match the program. If two programs have an equal number of matching resources, z/OS Debugger selects the older profile.

Before you begin, verify that you prepared your CICS program as instructed in Preparing a CICS program.

To start z/OS Debugger under CICS by using DTCN, do the following steps:

  1. If you chose screen control mode, start the DTSC transaction on the terminal you specified in the Display Id field.
  2. Run your CICS programs. If z/OS Debugger identifies a task that matches a DTCN profile, z/OS Debugger starts. If you chose screen control mode, press Enter on the terminal running the DTSC transaction to connect to z/OS Debugger.
