z/OS is a 64-bit operating system for IBM z/Architecture mainframes, introduced by IBM in October 2000. It derives from and is the successor to OS/390, which in turn was preceded by a string of MVS versions. Like OS/390, z/OS combines a number of formerly separate, related products, some of which are still optional. z/OS has the attributes of modern operating systems, but also retains much of the older functionality originated in the 1960s and still in regular use—z/OS is designed for backward compatibility.
The Jakarta Messaging API is a Java application programming interface (API) for message-oriented middleware. It provides generic messaging models, able to handle the producer–consumer problem, that can be used to facilitate the sending and receiving of messages between software systems. Jakarta Messaging is a part of Jakarta EE and was originally defined by a specification developed at Sun Microsystems before being guided by the Java Community Process.
The IBM Information Management System (IMS) is a joint hierarchical database and information management system that supports transaction processing.
IBM CICS is a family of mixed-language application servers that provide online transaction management and connectivity for applications on IBM mainframe systems under z/OS and z/VSE.
In computer science, message queues and mailboxes are software-engineering components typically used for inter-process communication (IPC), or for inter-thread communication within the same process. They use a queue for messaging – the passing of control or of content. Group communication systems provide similar kinds of functionality.
Tuxedo is a middleware platform used to manage distributed transaction processing in distributed computing environments. Tuxedo is a transaction processing system or transaction-oriented middleware, or enterprise application server for a variety of systems and programming languages. Developed by AT&T in the 1980s, it became a software product of Oracle Corporation in 2008 when they acquired BEA Systems. Tuxedo is now part of the Oracle Fusion Middleware.
WebSphere Application Server (WAS) is a software product that performs the role of a web application server. More specifically, it is a software framework and middleware that hosts Java-based web applications. It is the flagship product within IBM's WebSphere software suite. It was initially created by Donald F. Ferguson, who later became CTO of Software for Dell. The first version was launched in 1998. This project was an offshoot from IBM HTTP Server team starting with the Domino Go web server.
In computing, Advanced Program to Program Communication or APPC is a protocol which computer programs can use to communicate over a network. APPC is at the application layer in the OSI model, it enables communications between programs on different computers, from portables and workstations to midrange and host computers. APPC is defined as VTAM LU 6.2
IBM App Connect Enterprise is IBM's premier integration software offering, allowing business information to flow between disparate applications across multiple hardware and software platforms. Rules can be applied to the data flowing through user-authored integrations to route and transform the information. The product can be used as an Enterprise Service Bus supplying a communication channel between applications and services in a service-oriented architecture.
MessagePlus/Open is a communication platform for medium to large organizations designed specifically to handle high volumes of traffic within a high-availability environment. Currently supported communication channels include fax, fax over IP, e-mail and SMS, together withvarious options for integration with business applications. The product has been developed by INTERCOPE GmbH, Germany and is sold by both Intercope and IBM. It was previously known as FaxPlus/Open.
Amazon Simple Queue Service is a distributed message queuing service introduced by Amazon.com as a beta in late 2004, and generally available in mid 2006. It supports programmatic sending of messages via web service applications as a way to communicate over the Internet. SQS is intended to provide a highly scalable hosted message queue that resolves issues arising from the common producer–consumer problem or connectivity between producer and consumer.
An access method is a function of a mainframe operating system that enables access to data on disk, tape or other external devices. Access methods were present in several mainframe operating systems since the late 1950s, under a variety of names; the name access method was introduced in 1963 in the IBM OS/360 operating system. Access methods provide an application programming interface (API) for programmers to transfer data to or from device, and could be compared to device drivers in non-mainframe operating systems, but typically provide a greater level of functionality.
Telecommunications Access Method (TCAM) is an access method, in IBM's OS/360 and successors computer operating systems on IBM System/360 and later, that provides access to terminals units within a teleprocessing network.
A message queueing service is a message-oriented middleware or MOM deployed in a compute cloud using software as a service model. Service subscribers access queues and or topics to exchange data using point-to-point or publish and subscribe patterns.
Middleware analysts are computer software engineers with a specialization in products that connect two different computer systems together. These products can be open-source or proprietary. As the term implies, the software, tools, and technologies used by Middleware analysts sit "in-the-middle", between two or more systems; the purpose being to enable two systems to communicate and share information.
OS 2200 supports all commonly used, and many not so commonly used, distributed processing protocols, APIs, and development technology.
IBM WebSphere Optimized Local Adapters (OLA or WOLA) is a functional component of IBM's WebSphere Application Server for z/OS that provides an efficient cross-memory mechanism for calls both inbound to WAS z/OS and outbound from z/OS. Because it avoids the overhead of other communication mechanisms, it is capable of high volume exchange of messages. WOLA is an extension to the existing cross-memory exchange mechanism of WAS z/OS, with WOLA providing an external interface so z/OS address spaces outside the WAS z/OS server may participate in cross-memory exchanges. WOLA supports connectivity between a WAS z/OS server and one or more of the following: CICS, IMS, Batch, UNIX Systems Services and ALCS. WOLA was first made available in WAS z/OS Version 7, Fixpack 4 (7.0.0.4). Functional enhancements have appeared in subsequent fixpacks as documented in this article.
MQTT is a lightweight, publish-subscribe, machine to machine network protocol for message queue/message queuing service. It is designed for connections with remote locations that have devices with resource constraints or limited network bandwidth, such as in the Internet of Things (IoT). It must run over a transport protocol that provides ordered, lossless, bi-directional connections—typically, TCP/IP. It is an open OASIS standard and an ISO recommendation.
Distributed Data Management Architecture (DDM) is IBM's open, published software architecture for creating, managing and accessing data on a remote computer. DDM was initially designed to support record-oriented files; it was extended to support hierarchical directories, stream-oriented files, queues, and system command processing; it was further extended to be the base of IBM's Distributed Relational Database Architecture (DRDA); and finally, it was extended to support data description and conversion. Defined in the period from 1980 to 1993, DDM specifies necessary components, messages, and protocols, all based on the principles of object-orientation. DDM is not, in itself, a piece of software; the implementation of DDM takes the form of client and server products. As an open architecture, products can implement subsets of DDM architecture and products can extend DDM to meet additional requirements. Taken together, DDM products implement a distributed file system.
Enduro/X is an open-source middleware platform for distributed transaction processing. It is built on proven APIs such as X/Open group's XATMI and XA. The platform is designed for building real-time microservices based applications with a clusterization option. Enduro/X functions as an extended drop-in replacement for Oracle Tuxedo. The platform uses in-memory POSIX Kernel queues which insures high interprocess communication throughput.
