CEMT—master terminal
Chapter 11. CEMT—master terminal
Use CEMT to invoke all the master terminal functions.
The master terminal program provides dynamic user control
of the CICS system. By using this function, an operator can
inquire about and change the values of parameters used by
CICS, alter the status of the system resources, terminate
tasks, and shut down the CICS system.
The following transactions are subsets of CEMT (that is, they
contain some but not all of the functions of CEMT):
CEBT for alternate CICS systems (see page 21)
CEOT (see page 213)
CEST (see page 219).
The CECI transaction (see page 31 ) ) also uses the same
command interpreter as CEMT.
You can start CEMT from IBM 3270 family display devices or
equivalent terminals or from the system console. Starting
CEMT from the operating system console is described in
“The system console as a CICS terminal” on page 5. The
description of CEMT throughout this section assumes, unless
stated otherwise, that you are using a 3270 family display
device or equivalent terminal.
To start CEMT, you can either enter the identifier CEMT on
the command line by itself, or you can add options on the
same line, separated by commas or blanks, to form a
complete request.
If you start the transaction by entering CEMT by itself and
pressing ENTER, you get a display that prompts you for
more information, as described in “CEMT INQUIRE
SYSTEM” on page 116.
Starting the CEMT transaction
You can construct a CEMT request in stages, or you can
enter a complete request in one go. The CEMT transaction
checks the syntax of requests and diagnoses errors. If your
request is syntactically correct, it is processed immediately. If
your request cannot be processed because of severe syntax
errors, the full syntax of your request is displayed.
If you put a question mark (?) in front of your request, the
syntax of your request is displayed but it is not processed.
After you have initiated the CEMT transaction, you need not
reenter CEMT on subsequent requests, because the
identifier is implied at the beginning of any further request.
However, if you are using the system console, you must
always start each master terminal request with CEMT.
Enter CEMT on the command line of the screen, as follows:
