who maintain the production support

Production Support is a department, or part of a department, that supports production applications. They may support online and batch or just batch - in my experience. Sometimes online support is done by another group.

The activities will vary from shop to shop - when I was last doing it it involved first-line fixes (code fixes were done by the application development team), distribution of output, scehduling one-off requests, ensuring the right jobs were scheduled and dependencies checked, library maintenance approval, reviewing application change documents, recording statistics for monthly review with the users (complete with reasons for not hitting 100% jobs on time or TP up), proactive fixes - mainly around space allocation/usage and many other bits of trivia.

The canteen and coffee machine maintains application support.

In addition to Nic's description, in my experience, Production Support literally owns the production environment. They code the JCL and coordinate the library and application changes. They own all of the data migration and/or exchange processes. They reach out to the application support teams when needed. They assure that production batch windows and service levels are met, or at least provide reasons if they don't. They sometimes fix corrupted data. They script and perform application tests to assure the availability and accuracy of systems to the business customers.
