This video describes OTMA (Open Transaction Manager Access), which is a component of an IMS Control Region. OTMA provides an architected interface that permits it to communicate to devices through a…

This video describes Advanced Program-to-Program Communication (APPC), which is the IBM-proprietary SNA (Systems Network Architecture) implementation of client-server processing.
|
|
This video describes IMS processes and stores information from a conversation, which is defined as a dialog between a user at a terminal and IMS through a scratchpad area (SPA) and one or more…

|
This video describes several DL/I function codes for IMS TM calls that have the same function code as IMS DB DL/I calls.
|
|
This video describes how you use IMS generation to define all of transactions and programs to IMS.
|
|
This video describes how dynamic transaction backout is invoked automatically when a program ABENDs (abnormally ends).
|
|
This video describes how you can use the option to have the program already in the storage of the MPR region without needing it to be fetched from a load library.
|
|
This video describes how you can use the wait-for-input option, which results in dedicating an MPR to a single transaction-program so that it is always ready if a transaction arrives.
|
|
This video describes how you can configure parallel scheduling to have the same program and transaction run in more than one dependent region at the same time.
|
|
This video describes how a simple COBOL application might be coded as an MPR.
|
|
This video describes a transaction flows through an MPR.
|
|
This video describes how the IMS Scheduler serves as a “matchmaker” and assigns work that needs to be done (messages) to an MPR or JMP that is capable of processing that particular work.
|
|
This video describes how the IMS Scheduler selects an instance of a transaction for processing by a MPR based on the Class and Priority of the transaction. The Class and Priority are specified as…
|
|
This video describes how messages flow through IMS.
|
|
This video describes the MTO LTERM, which controls the IMS system and various commands that you can run on a master terminal versus a remote terminal.
