Basic I/O Concepts The combination of I/O devices, device drivers, and the I/O subsystem comprises the overall I/O system in an embedded environment The purpose of the I/O subsystem To hide the device-specific information from the kernel as well as from the application developer To provide a uniform access method to the peripheral I/O. I believe you are referring to MVS and JCL. MVS is the operating system for the IBM mainframe systems and JCL is the job control language for the mainframe. You could correlate MVS to Linux and JCL to Bash for example. The AS/ / iSeries / IBM i / i5 is considered a midrange machine. It's operating system is called OS/ or more recently i5/OS.
He also holds a Masters Degree in Computer Science, a Doctorate in Informatics, and has also attended the National Test Pilot School. Dr. Artis has written more than papers related to computer performance and evaluation, is a co-author of the book MVS I/O Subsystems, and has taught seminars on z/OS and Open Systems I/O on six continents. Dr. MVS does have a type of a file system but it is a bit different from how file systems are implemented on Linux, Unix, Windows, etc. For MVS the file system is maintained by the VTOC (Volume Table of Contents). Basically it keeps up with what tracks on the disk belong to which data sets. Tommy Sprinkle on I/O Reference Summary;.
EXCP is the facility that allows us the ability to perform device-level I/O without having to the heavy lifting. It handles the details like pagefixing buffers, scheduling an I/O request, and processing interrupts so we don’t have to worry about these things.

The job entry subsystem that MVS uses to do work. It can be either JES2 or JES3. Secondary subsystems. Secondary subsystems provide functions as needed by IBM products, vendor products, or the installation.

The UCBs are stored in system-owned memory, in the Extended System Queue Area (ESQA).After IPL completes, UCBs are owned by Input/Output Support.
Some of the. Pat Artis is a well-known expert in workload characterization, forecasting, simulation modeling, I/O subsystem design and capacity planning.
He received the A. Michelson Award for his fundamental contributions to computer metrics is the co-author of the book MVS I/O Subsystems: Configuration Management and Performance Analysis. This book resolves that problem by presenting the design philosophy of each topic and moves in a naturally progressive way from each area to the next, from hardware to MVS internals, to software (both maintenance i.e., SMP/E, and Utilities) to MVS initialization, to JES, networking, and to I/O devices and their by: 2.
While a variety of conceptual models might be proposed to explain the performance characteristics of these subsystems, this paper will focus on the author's paradigm of a physical I/O subsystem within the logical MVS I/O subsystem and the sibling PEND which results from collisions within the physical disk subsystem.
MVS/ is a generic term for all versions of the MVS operating system prior to MVS/XA. [NB 5] The System/ architecture, at the time MVS was released, supported only bit virtual addresses, so the MVS/ operating system architecture is based on a bit per: IBM.

Expanding the Horizons of Mainframe I/O. Today, analysts who are responsible for z/OS I/O subsystems face a changing environment and a variety of new technologies as traditional mainframe environments attempt to exploit new technologies such as FICON Express16S, High Performance FICON for z, EC12 and z13 processors, flash.
Another disadvantage to the 80x86's I/O address space is that it is quite small. Although most peripheral devices only use a couple of I/O address (and most use fewer than 16 I/O addresses), a few devices, like video display cards, can occupy millions of different I/O locations (e.g., three bytes for each pixel on the screen).
A presentation at SHARE5 MarchAustin, Texas, by Jay Maynard of Savail Consulting, Inc. Explores the addition of bit architecture into MVS Size: 83KB. The MVS I/O module provides the isolated, short-circuit current-limited power required to connect up to six remote MVS transmitters (see Specification Sheet MVS).
The MVS I/O module provides EIA (RS) communications and power to external remote MVS transmitters. Each connected MVS transmitter is scanned onceFile Size: 41KB.
makes MVS ideal for doing huge jobs involving lots of I/O. Two acronyms that come up when people discuss batch jobs are JES2 and JES3. These are two versions of the Job Entry Subsystem, the part of MVS that deals with the scheduling of batch jobs.
You need not worry about JES, but you may hear people refer to Size: KB. ,MVS/ESA (TM) SP Version 5 Release 1 (MVS ) improves the cost effectiveness ofthe S/ (R) platform by addressing key areas of software and systemsmanagement costs. In addition, MVS supports the S/ Parallel Sysplex.

The first category of macros defines the system hardware configuration. They are needed because MVS must know about every I/O device that is attached to the system. As a result for every I/O added, the system must be generated. JES2 compared to JES3. z/OS concepts IBM ® provides two kinds of job entry subsystems: JES2 and JES3.
In many cases, JES2 and JES3 perform similar functions, but most installations use JES2. Both JES2 and JES3 read jobs into the system, convert them to internal machine-readable form, select them for processing, process their output, and purge them from the system.
