What is Cedf in mainframe?
CEDF allows you to intercept your application programs at the program’s initiation, at each CICS command, and at the program termination. CEDF helps you to isolate and focus on problems in your application programs. Using the CEDX transaction. Use CEDX to monitor and debug non-terminal transactions.
For what is the CEDF transaction used?
CEDF is the transaction identifier that is used to start or stop an Execution Diagnostic Facility (EDF) session on a terminal or a region. EDF enables you to test, online, an application program that has been preprocessed by using the -e option of the CICS translator (cicstran), without modifying the program.
How to turn CEDF off?
To Turn Off Debugging
- Type the CEDF,OFF transaction on a blank transaction screen.
- Press PF3 on the Debug Processor main screen (FIGURE 14-2).

What is pseudo conversation in CICS?
Pseudo-conversational transactions are used in CICS® application programs that consist, internally, of multiple tasks that are designed to appear to the operator as a continuous conversation. The program issues an EXEC CICS RETURN request with the TRANSID option.
How do I release a CICS program?
RELEASE releases the program, table, or mapset previously loaded by a LOAD command. This means that the issuing task can no longer use the resource unless another LOAD is issued. Note: RELEASE does not remove a program from storage.
How is CEDF used in execution diagnostic facility ( EDF )?

When to run CEDF to debug a transaction?
When you run CEDF to debug a transaction, the transaction runs, sets a flag, and exits, all in a very short time.
