Running the debugging transactions

To run the CICSPlex SM debugging transactions, log on to a CICS® system and enter CODU or CODB.

COD0
To use the method-level debugging transaction, as described in Method-level debugging with COD0. This transaction provides access to CICSPlex SM objects, methods, message argument lists (MALs), and outstanding requests. To exit this transaction, type EXIT on the command line.
CODB
To use the system-level debugging transaction, as described in System-level debugging with CODB. This transaction provides access to address space and data space storage, major control blocks, data queues, and CICSPlex SM entries in the CICS trace table. To exit this transaction, press PF3 or type END on the command line.
The following usage rules apply to the COD0 and CODB transactions:
  • You issue a COD0 command by typing the command name on the command line. You issue a CODB command by typing its option number on the command line.
  • The standard END and CANCEL commands are recognized. END completes the task in progress and returns you to the previous screen, while CANCEL cancels the task before returning.
  • You can scroll a display by using the commands DOWN, UP, TOP, and BOT. With COD0, you can also enter a default scrolling amount in the Scroll==> field.
  • On a selection list, any character that is not a blank or an underscore can be used to select an option.
  • These transactions support only 3270 model 2 screens that is, 24x80 and 32x80 type screens.
