What is CICS (Customer Information Control System)

CICS (Customer Information Control System) is an online transaction processing (OLTP) program from IBM that, together with the COBOL programming language, has formed over the past several decades the most common set of tools for building customer transaction applications in the world of large enterprise mainframe computing

IBM markets or supports a CICS product for OS/390, UNIX, and Intel PC operating systems. Some of IBM's customers use IBM's Transaction Server to handle e-business transactions from Internet users and forward these to a mainframe server that accesses an existing CICS order and inventory database.

Package : MS –Office XP

Certification:
IBM Mainframes Certification from Hinduja TMT Ltd, Bangalore.

Project Profile:
ATM Transaction Management System
Module handled : Account information provider
Software : IBM Mainframes
Operating System : MVS, Z/OS - 390
Host Language : COBOL
Compiler : JCL
RDBMS/Backend : DB2
Description: This module will access the master database and generate the respective account information for those accounts with correctly entered passwords. It will generate various screens relevant to each transaction .Screens involved in this module designed using CICS and COBOL is used as host language. The database consists accounting information of customer like name, address, account number, password, amount deposited, retrieved. Once the password entered matches, this module will display account information.If, not the necessary instructions containing screen to proceed will comes into picture.

How Do you run/execute the Program/Job in a specific time/date in CICS?

I don't think that ASKTIME command is going to work here as this only gives you the current date and time. If you want to start the task at a particular time you can use

EXEC CICS START
TIME(HHMMSS)
END-EXEC.

This will start the CICS task at the time specified. But I have no idea about giving the dates

How do I find the name of the CICS region inside my COBOL program?

EXEC CICS
ASSIGN APPLID (COMM-HOLD-REGION-ID)
RESP (WS-CICS-RESPONSE)
END-EXEC.
.
.
test WS-CICS-RESPONES code here for '00'
.
.
EVALUATE COMM-HOLD-REGION-ID
WHEN 'TESTREG

WHEN 'PRODREG'

WHEN OTHER

END-EVALUATE.
