    The user keys TRAN1 on a screen and hits enter
    The enter key allows the data on the 3270 to be sent to CICS
    The first four bytes are used as the transaction code (TRAN in this case) -- any remaining bytes are user data
    CICS looks up the transaction code in its tables and verifies that the transaction can be executed. If not, abend
    CICS checks to see if the program referenced in the transcation is valid. If not, abend
    CICS checks to see if the program referenced in the transaction has been loaded from disk yet. If not, it is loaded
    CICS transfers control to the program referenced in the transaction
    The program starts executing

My question might sounds rank beginner, however, I'm trying to learn it as professional but in vain. The question is about concepts:

Let's say, I've created a Transaction (TRAN1) and in CICS region I've entered the TRAN1 and press the enter key. What are the tasks and the "objects" will come to play before the actual screen is shown to the user. I read it like, a TASK is created and then it eventually goes to KCP but it's confusing. Can someone please share his/her experience. That will be of great help. Also, do someone know of some document which might show all the "functions goes behind the scene" in a pictorial representation...

Any help in this regards is much appreciated.

We got 121 users online Yesterday, on 17 Jul 2013 at 22:54. You can check that at the bottom of Board Index. This will be shown like this: "Most users ever online was 121 on 17 Jul 2013 22:54".

That's a great achievement.

Thanks for Liking and showing the trust in to the Labor we're putting in, much appreciate that,

Should I say, this is just kind of a rule?

Quote:

Question
How do you find CICS product documentation for CICS Transaction Server for z/OS (CICS TS), CICS on z/VSE, and the CICS tools?
Answer
The best place to find CICS product documentation is to use the CICS TS information centers. Documentation for the latest versions of the CICS Tools is also included in the CICS TS information centers. Each release of CICS has its own information center that you can view on the http://www.ibm.com web site or install on a workstation or server.
For information on CICS for VSE, see the z/VSE documentation page for a list of libraries. Note that the VSE documentation is not available in an information center.

The CICS information centers are powered by Eclipse technology and run on a number of platforms, including z/OS. Each information center contains a number of document plug-ins that contain the CICS documentation in HTML and PDF formats. A plug-in is a set of files that are designed to run in an Eclipse framework. See the Eclipse website for more information.

2. Generate a map, compile the program using the copy book, and much will be clearer. The map compile generates the appropriate -I, -O, -A, -L, -F subscripts for named map fields automatically.

3. Values are not mapped -- fields are mapped. Values are the data stored in the field. PICIN and PICOUT merely describe the data and provide the context for understanding / editing the data.

As the physical map is about the screen alignment and the field positions, how the values entered in the field which has PICIN or PICOUT clause in Physical map gets mapped?

Does that mean data sent/received to the physical map should be constant?

How does the data in Symbolic map gets converted with 5 suffixes namely F,L,A,I and O.

For example EMPNO is treated as EMPNOI, EMPNOO, EMPNOA, EMPNOL and EMPNOF. How does this happen in symbolic map?

I read about it but I'm confused about this and so the post.

As commonly used, the term usually applies to major software products such as database managers, transaction monitors, Web servers, and so forth. Subsystem is another term often used for this type of software. These software products are usually licensed programs, although there are notable exceptions, such as the HTTP Server.

As this Forum deals mainly with Mainframes let's talk about zOS related middleware. Typical z/OS middleware includes:

  • Database systems
  • Web servers
  • Message queueing and routing functions
  • Transaction managers
  • Java™ virtual machines
  • Extensible Markup Language (XML) processing functions.

Please note that for members who prefer to view our site in 'mobile style' on a computer, we have an option to switch to 'Mobile View' while on computer also. You can find this option at the bottom of the index page just above the donation chest icon.

Please Note - in mobile-view, as of now, "basic blue color scheme" is the only standard theme at the moment - so you might see "green changing to blue" while in 'mobile-view' or seeing the site on a mobile.

Enjoy! :)

CICS is middle ware designed to support rapid, high-volume online transaction processing. A CICS transaction is a unit of processing initiated by a single request that may affect one or more objects. This processing is usually interactive (screen-oriented), but background transactions are possible.CICS provides services that extend or replace the functions of the operating system and are more efficient than the generalized services in the operating system and simpler for programmers to use, particularly with respect to communication with diverse terminal devices.

CICS manages the sharing of resources, the integrity of data and prioritization of execution, with fast response. CICS authorizes users, allocates resources (real storage and cycles), and passes on database requests by the application to the appropriate database manager (such as DB2®). We could say that CICS acts like, and performs many of the same functions as the z/OS operating system. A CICS application is a collection of related programs that together perform a business operation, such as processing a travel request or preparing a company payroll. CICS applications execute under CICS control, using CICS services and interfaces to access programs and files.
