For six years i have been a mainframe developer.. I have this thought process for a long while, how this environment is build..

1. say for example.. what we write in a PS a file where it is stored and how it is managed. (Mainframe storage admin.. i guess..)

2. and how the DB2 statements works. say for example. There is a select statement. hpw the system recognise this select statement. and how the coding would have been done for select operation itself in db2.. and which language they would have written these commands.

3.How the cics system is built of.. what are the things required to do a cics system programming..

basically, what i am trying to ask how mainframe is grown.. and how it is build and what it required to learn them

After 6 year being a mf developer, why ask this basic stuff? You should have known by now.

Or at least know where to look (the IBM manuals), principle of operation, A-Z of z/OS, redbooks, etc.

a good place to start for the basics concepts that You need to get acquainted with is here
http://www.redbooks.ibm.com/abstracts/sg246366.html?Open

and follow on by searching Yourself the IBM redbooks collection for the series
ABC of zOS System programming

Hello,

I suspect you do not realize the magnitude of those 3 questions.

Most people, working more closely with the underlying technology than you hyave been exposed to, cannot completely answere all of these "on their own". Much can be found by lots of research and it will still most likely be incomplete because there is just too much, used in too many ways, and is constantly changing.

We also have a separate forum for Students and Beginners questions:
www.ibmmainframeforum.com

Some years of experience does not always mean there cannot be basics that need clarification. Many "developers" successfully "use" things that they have no idea how they work. Some of us are more curious icon_cool.gif

When you continue, suggest you reduce the scope of your questions and possibly start a new topic for each as they are not much related.

We shall continue the discussion of how DB2 syntax work ( trying to summarise here.). Eg. When we type a syntax SELECT. how system recognize.. and how the coding is been done for SELECT statement..

why should we waste time discussing what You clearly know little about ?

start by getting a bit of training, meditate on the manuals, and if there is soemthing You do not understand just ask SINGLE and clear questions.

up to now what You asked ( all questions ) for can be summarized in about 50 manuals
too much to be rewritten for forum answers ..

as already said You might be better off here
http://ibmmainframeforum.com/index.php
a very strong suggestion to migrate


what is that You did not like in the link I suggested to look at ???
and the follow on redbooks

probably You do not want to spend Your time reading and You want us to waste our time rewriting the manuals

Hello,

Quote:

Where might you type this SELECT? A SELECT can be "typed" several places. . .

In a program.
In SPUFI or some other only dynamic query tool.
Several utilities.
The "system" doesn't actually "recogize" the SELECT. The process being used (compiler, spufi, utility, etc) has SELECT as one of the valid statements and knows how to turn it into something db2 can use. One easy to see this is to run a db2/cobol program thru the pre-compiler and see how the SQL statements are modified before being compiled.

You're actually asking a very trivial (and a vital one at the same time)question. Possibly, you should spend some time in understanding How Computers Work and then relate that to the links provided in this thread already...
