HI,
This may be a Weird question....Can we implement Multithreading in Batch...

My main module(COBOL) of our application is both accessed by online and batch programs.

So i thought of calling this program in mulithread passion, from another program so that we can save time.


I heard we can do interrupt handling in PL/1.....So i thought of calling my main module from this PL/1 in an multhithreaded passion...


Like i will give input and call my mainmodule and i will not wait for the control to comeback from mainmodule ...before that i will give another input and trigger another thread....

I see its possible in CICS...Just wanted to check..if this is possible in batch as well using PL/1 or assembler or even COBol(if possible)...


Any inputs are welcome....

Any thoughts ...

Thanks in advance...

harikiran2001,

1. Click on "Quick Manuals" Link at top of this page.
2. Click on Enterprise COBOL Programming Guide
3. Scroll down to chapter 4.4 and read it

You need to understand the concept of multithreading fully before you can implement it

Papadi,

I just don't get as to why this is a "Special solution "? Enterprise COBOL support isn't going away. Why can't he implement this?

Thanks for every body input....I still go through the manuals...But just first thought of replying to "dbzTHEdinosauer" mean while.

This is what my requirement is ...

My main module is accessed both by java programs(GUI) as well as batch programs(cobol) and hence i can say for sure it supports multithreading(GUI)....

But in the batch for now this main module is called from a cobol program in a normal passion...So the cobol pgm reads an input file and gives the first record as input to the mainmodule...

and when control comes back after prcoessing the record1 , it reads anothe record from the file and give it as another input and calls mainmodule...


So this what i want to do..

At a time i will read ten record...

and hit ten calls to the programs and ten threads will be executing parallely and i will get acknowledgement back from the threads... i will hit another ten...

trigger (record1)
trigger(record 2)-- no wait here to control to come back from the called module
trigger (record3)--"" "" ditto"" """

capture(acknoledgment record1)
capture(acknoledgment record2)
Capture(acknoledgment record3)

Thanks in advance...









i gives input to mina module parameters and

I will make no comment on:

Yeap Dick Brenholtz...

Thats what i am thinking on....

COuld you please show me some direction...

[Nic Clouston]

Kolusu gave you "some direction". Reading the first part of that section it would seem that, although a COBOL module can run in multiple threads, the threads would have to be creted and controlled by a 'thread-aware' language.

Hi Kolusu,

[harikiran2001]

Well...I see my main module is prepared for the Multithreading...But i want to know if i can write the driver program in PL/1 to trigger the threads....

It would be great, If i could get one exmaple program.


Thanks in advance...
