- MTCS
MTCS (Minimum Teleprocessing Control System) was a
transaction server that ran onIBM mainframe systems underOS/VS1 .MTCS was available from
IBM and designed for rapid, low to medium volume online processing. This process was entirely interactive (screen-oriented using3270 display terminals).The 'official' version of MTCS was single thread only and was a forerunner of
CICS before it was released.An unofficial and multi-threaded version of MTCS was developed by Littlewoods Pools,UK at the same time as a multi-threaded "MTCS bridge" (middleware MTCS simulator) became available for running MTCS transactions directly under CICS. This version was also used by other customers under a license agreement.Transactions
An MTCS transaction is a set of operations which together perform a task. Usually, the majority of transactions are relatively simple tasks such as updating the balance of an account.
MTCS applications comprise transactions which were written in IBM Basic Assembly Language and interfaced with
3270 terminals.Each MTCS program was initiated using a transaction identifier. MTCS screens were sent as native
3270 datastreams to the terminal.History
The first release of MTCS was made available prior to the first release of
CICS in the late1960 s.A forerunner of MTCS was known as "FASTER" and was a higher levelBTAM based product that controlledIBM 2260 display terminalsee also
