This video describes some of the tools that you can use with IMS Transaction Manager.

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.
