Transaction Processing Management System

Transaction Processing Management System (TPMS) is an online transaction processing superstructure software from ICL (now Fujitsu Services) that runs on their VME mainframe computers. The first versions were released in the mid-1970s and were sold worldwide.

Structure

The service runs in at least two Virtual Machines (VMs)

a Control VM (CVM), responsible for connecting, disconnecting terminals and routing messages
one or more Application VMs (AVMs), responsible for all application processing - receiving input messages and returning output messages.

gollark: I'm not really sure.

gollark: No, at least in this field they're frequently made by large well-funded teams, but it just takes ages for support to be implemented anywhere.

gollark: I mean, apart from support, AVIF is not very good in terms of being supported by anything at all, but it's technologically superior.
