I know what is AOR and TOR but not in details. I don't understand where they fir in CICS architecture. Are they part of each CICS region, if yes, can someone explain what are the purpose of these regions.

AOR - Application Owning region
TOR - Terminal Owning region
All the termianal related programs (Translator, co-ordinator) will be coded in TOR and API (Application program interface) will be coded in AOR.
To put in simple words - screen handling , function keys logic, function keys validations will be in programs coded in TOR and all business logic (valid processing, updating the database) in AOR.

TOR ---> AOR which interacts with DOR (Data owning region)

Yes, T/A/DOR R - region |

Hello,
AOR (Application Owning Region) and TOR (Terminal Owning Region) are used by MRO (Multiple Region Option) for load balancing and control. Users log into terminals attached to a tor and from there access an application in an aor. |

Thanks for quick replies..
Aaru,
I have a doubt on following statement(marked in bold).
To put in simple words - screen handling , function keys logic, function keys validations will be in programs coded in TOR and all business logic (valid processing, updating the database) in AOR.
But all the above are normally part of one application program. Can u pls clarify.

When you say "one application program" Is that one program or collection of programs?
In the online project that I had worked on, for any business logic or functionality We would code pgm A in TOR and B in AOR.
A would have code for screen validations, pre-requisite checks and terminal related commands and B would have the business logic coded. |

This is not the industry normal practice.
TOR handles the terminal I/O driven by applications residing in
the AOR.
As Dick pointed out, TOR/AOR is part of MRO environment to handle
load balancing. |

Thanks Earl,
I also feels the same as I hvae not seen doing this in any of our project so far. I am not sure if an application programmer can define that out of 100 programs 10 shoould be part of TOR and 90 as AOR. If yes, I would like to know how ? I feel TOR consist of system programs which handle terminal I/O operations and the programs written by application programmer as part of AOR. I guess this is decided by CICS as part of load balancing. Pls explain.
Thanks,
Rakesh |

Rakesh,
To explain would be lengthy. You need to ask your co-workers
for additional information regarding TOR/AOR (or your CICS Technical
support).
Is there any CICS training classes available to you in India?
Thanks,
Earl |

Hello,
Is the interest in mro because of performance problems with an existing application or is this in anticipation of some new large application?
If this is to deal with an existing poorly performing application, suggest the time will be better spent improving the performance of the existing code/design.
Implementing mro is not a good choice for dealing with an application that has been poorly designed and/or coded. |
