viii CICS Supplied Transactions

Preface

What this book is about

This book tells you how to start the transactions supplied with CICS. It tells you how to

control the CICS system, how to send messages, how to collect statistics, and how to get

terminal error information. It is also useful if you are responsible for preparing procedures for

people who operate such terminals.

The book also describes how you can use the operating system console as a CICS terminal.

Who should read this book

This book is intended for CICS terminal operators and persons responsible for preparing

terminal operating procedures. It is also useful for both system and application programmers.

What you need to know to understand this book

A general knowledge of the concepts and terminology is required.

How to use this book

This book is mainly for reference. After a short introduction, the rest of the book is arranged

in alphabetic order of the transaction identifier. An index is provided to pinpoint individual

transactions and keywords.

Some CICS transactions are described in greater detail in other CICS books. These include:

In these cases, this book contains a brief description of the transaction and indicates where

further information is to be found.

Determining if a publication is current

IBM regularly updates its publications with new and changed information. When first

published, both hardcopy and BookManager softcopy versions of a publication are usually in

step. However, due to the time required to print and distribute hardcopy books, the

BookManager version is more likely to have had last-minute changes made to it before

publication.

xii CICS Supplied Transactions

Subsequent updates will probably be available in softcopy before they are available in

hardcopy. This means that at any time from the availability of a release, softcopy versions

should be regarded as the most up-to-date.

For CICS Transaction Server books, these softcopy updates appear regularly on the

Transaction Processing and Data Collection Kit

CD-ROM, SK2T-0730-xx. Each reissue of

the collection kit is indicated by an updated order number suffix (the -xx part). For example,

collection kit SK2T-0730-06 is more up-to-date than SK2T-0730-05. The collection kit is also

clearly dated on the cover.

Updates to the softcopy are clearly marked by revision codes (usually a “#” character) to the

left of the changes.

xvi CICS Supplied Transactions

introduction

Chapter 1. Transactions supplied by CICS

CICS provides operations, usually initiated from terminals,

called

transactions

, each of which involves the use of CICS

tables, programs, and internal services. This book deals with

those transactions that are supplied by CICS and which, in

addition, have an operator interface.

CICS transactions have identification codes that start with “C”

and are 4 characters long; for example, CEMT.

The following table shows the transactions that are described

in this book. For a more complete list of CICS transactions,

including those that do not have an operator interface, see

the Appendix, “List of CICS transactions” on page 263.

In general, you start a CICS transaction by entering its

transaction identifier (for example, CEMT). The transaction

identifier is used by CICS to identify the programs that

handle the specified transactions, and to establish a task to

process them.

If you use an IBM 3270 system display or similar display

device that has the appropriate features installed, you can

also start a transaction by a program function (PF) key or

program attention (PA) key, by an operator identification card

reader, by a magnetic slot reader, or by a light pen. For other

types of terminals or subsystems, see the appropriate

CICS/OS/VS subsystem guide.

Upgrading CICS transactions

You may wish to apply a CICS-supplied upgrade, but are

using modified versions of one or more CICS-supplied

transactions or of the CICS-supplied calling programs that

handle CICS-supplied transactions. After you have first

copied them to differently named groups, you must replace

these private versions from the upgraded CICS-supplied

version and modify them afresh to ensure that the necessary

upgrade changes are carried out. Failure to do this can lead

to unpredictable results.

How to start or stop a transaction

You start a CICS transaction by pressing the CLEAR key to

clear the screen, and entering the transaction identifier, either

by itself or followed by data, on the command line of the

screen. The command line is a single line, usually at the top

of the screen.

You can type the transaction identifier by itself and follow the

prompts until a complete transaction command is built up, or

you can type the complete transaction command on the

command line. If you do not enter enough information, or if

the information you enter is wrong, you are prompted to

complete or correct your input.

For example, in the following transaction, CEMT is the

transaction identifier and the additional data is INQUIRE

PROGRAM(PROG1).

CEMT INQUIRE PROGRAM(PROG1)

When the transaction starts, it processes the additional data.

At the completion of this transaction, you get the following

message:

STATUS: SESSION ENDED

After a transaction has completed, press the CLEAR key to

clear the screen in readiness for the next transaction. You

can cancel any request by typing CANCEL on the command

line.

introduction

Syntax notation and conventions used in

this book

Each command has a syntax box to show you what options

there are.

You interpret the syntax by following the arrows from left to

right. The conventions are:

Minimum abbreviation of keywords

In general, the CICS transactions accept as few characters

of a keyword as needed to identify it within the request. For

example, in a CEMT INQUIRE TASK command, you could

use TASK, TAS, or TA to uniquely identify TASK. T alone,

however, could be confused with TCLASS, TERMINAL,

TRACE, or TRANSACTION.

In the syntax displays on your screen (unless your terminal is

uppercase only), and in most cases in this book, the

minimum permitted abbreviation is given in uppercase

characters, the remainder in lowercase.

Uppercase input to transactions

In general, most CICS-supplied transactions accept only

uppercase input. If UCTRAN=YES has been specified in the

terminal definition, all lowercase characters, even those

enclosed within single quotation marks, are translated to

uppercase.

If you have to specify UCTRAN=NO for your terminal, you

have to ensure that the group specified for your terminal

refers to a profile that will carry out uppercase translation.

CICS provides a PROFILE definition, DFHCICSP, in the

DFHSTAND group in the CICS system definition (CSD) file.

This profile is identical to DFHCICST except that it specifies

UCTRAN(YES) instead of UCTRAN(NO).

The new profile is used by the CICS-supplied page retrieval

transaction, CSPG. The new profile, together with changes in

the task-attach routine and the page retrieval program,

enables CICS to perform uppercase translation at the

transaction level for BMS paging.

This allows users of terminals that are defined with

uppercase translation switched off to use the page retrieval

function without having to enter paging commands in upper

case. Assigning a new profile for CSPG means that all data

entered on the retrieval command (defined by the PGRET

system initialization parameter) and the purge command

(defined by the PGPURGE system initialization parameter) is

translated to uppercase.

If a user’s terminal is defined with UCTRAN(YES), the new

profile has no effect because all terminal input is translated

to uppercase anyway.

Terminal operators

A CICS system makes provision for the following classes of

operators:

 A

terminal operator

who can use a terminal to perform

routine transactions that cause application programs to

be processed. You can use a small selection of CICS

transactions. For example, you can inquire about, or

change, the status of your own terminal.

 A

supervisory terminal operator

who can perform all the

duties of a terminal operator, in addition to supervising

other operators within a functional group. Your operator

security code gives you access to the supervisory

terminal transaction, CEST, with which you can monitor

and control some of the system resources used by your

group.

 A

master terminal operator

who can monitor and control

resources in a CICS system. Your operator security

code gives you access to the master terminal

transaction, CEMT, with which you monitor and control

the system resources. Internal security checking may

limit the range of resources under your control.
