Hi,
one of my mainframe applications is going to retire in near future. Application has Online/Batch processing and has quite a few interfacing applications. Please let me know what all steps need to be taken to avoid any mistakes. Also if there are any tools available to make this process easier.
Thanks, |

| Do you have someone, at your shop, already supporting this application? This is pretty wide question, for me, to be answered via a Public Forum. |

Online/Batch processing ?
What kind of online are we talking here? IMS, CICS etc. |

Basically, that application is performing a business function. When the application is retired, how does the business function get performed? That is the basic question to be answered -- and there's not a lot of guidelines or tools on how to ensure the replacement does at least as much as the retiring application. Although consultants will happily come in and do that verification (for a nice hourly rate, of course).
Details will depend upon the application, and someone will need to look at each interface and determine how the data that will no longer be available will be replaced in the interfacing application. |

Please refrain from "expecting" an answer/reply. I would choose my Verbs differently.

What is your approach to retiring an application?
A soft way is to start by disabling access to online functions and disabling the run cycles of the targeted OPC batch operations, in cooperation with the business area's requirements for substituted or abandoned processes.
In next step you can then clean up the application environment, archiving library entities and removing definition in the online system. Cross reference scans should be made so you don't retire objects used in still active systems.
Databases and files might be kept for some time, based on legislative audit trail requirements for the business in question. |
