Program Temporary Fix
In IBM terminology, a Program temporary fix or Product temporary fix (PTF), sometimes depending on date, is a single bug fix, or group of fixes, distributed in a form ready to install for customers. A PTF normally follows an APAR (Authorized Program Analysis Report), and where an "APAR fix" was issued, the PTF "is a tested APAR" or set of APAR fixes. However, if an APAR is resolved as "Fixed If Next" or "Permanent Restriction" then there may be no PTF fixing it, only a subsequent release. PTF installation Initially, installations had to install service via a semi-manual process. Over time, IBM started to provide service aids such as IMAPTFLE and utilities such as IEBEDIT to simplify the installation of batches of PTFs. For OS/360 and successors, this culminated in System Modification Program (SMP) and System Modification Program/Extended (SMP/E). For VM, this culminated in Virtual Machine Serviceability Enhancements Staged (VM/SP SES) and VMSES/E. For DOS/360 and successors, ...

Patch (computing)
A patch is a set of changes to a computer program or its supporting data designed to update, fix, or improve it. This includes fixing security vulnerabilities and other bugs, with such patches usually being called bugfixes or bug fixes. Patches are often written to improve the functionality, usability, or performance of a program. The majority of patches are provided by software vendors for operating system and application updates. Patches may be installed either under programmed control or by a human programmer using an editing tool or a debugger. They may be applied to program files on a storage device, or in computer memory. Patches may be permanent (until patched again) or temporary. Patching makes possible the modification of compiled and machine language object programs when the source code is unavailable. This demands a thorough understanding of the inner workings of the object code by the person creating the patch, which is difficult without close study of the sourc ...

Authorized Program Analysis Report
An APAR (Authorized Program Analysis Report) (pronounced A-PAR, rhymes with far) is an IBM designation of a document intended to identify situations that could result in potential problems. It also serves as a request for the correction of a defect in current releases of IBM-supplied programs. The Process "Occasionally""Issues with Cognos and other IBM software can arise from configuration errors, problems in third-party hardware or software, and occasionally, because of a bug in the IBM product itself." IBM software has a bug. Once it has been ascertained that the situation has not been caused by problems in third-party hardware or software or the user's configuration errors, IBM support staff, if they suspect that a defect in a current release of an IBM program is the cause, will file a formal report confirming the existence of an issue. In addition to confirming the existence of an issue, APARs include information on known workarounds, information on whether a formal fix is sch ...

OS/360 And Successors
OS/360, officially known as IBM System/360 Operating System, is a discontinued batch processing operating system developed by IBM for their then-new System/360 mainframe computer, announced in 1964; it was influenced by the earlier IBSYS/IBJOB and Input/Output Control System (IOCS) packages for the IBM 7090/7094 and even more so by the PR155 Operating System for the IBM 1410/ 7010 processors. It was one of the earliestJust a few years after Atlas Supervisor, Burroughs MCP and GECOS operating systems to require the computer hardware to include at least one direct access storage device. Although OS/360 itself was discontinued, successor operating systems, including the virtual storage MVS and the 64-bit z/OS, are still run and maintain application-level compatibility with OS/360. Overview IBM announced three different levels of OS/360, generated from the same tapes and sharing most of their code. IBM eventually renamed these options and made some significant design changes: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
System Modification Program/Extended
System Modification Program/Extended (SMP/E), the proprietary version of System Modification Program (SMP), "is a tool designed to manage the installation of software products on z/OS system and to track the modifications" to those products. SMP/E manages multiple software versions, helps apply patches and updates ( PTFs), facilitates orderly testing and, if necessary, reversion to a previous state, allows a "trial run" pseudo-installation to verify that actual installation will work, keeps audit and security records to assure only approved software updates occur, and otherwise provides highly evolved, centralized control over all software installation on z/OS. Although it is possible to design and ship software products that install on z/OS without SMP/E, most mainframe administrators prefer SMP/E-enabled products, at least for non-trivial packages. Using SMP/E typically requires some working knowledge of Job Control Language (JCL), although most products supply sample JCL. Th ...

VM (operating System)
VM (often: VM/CMS) is a family of IBM virtual machine operating systems used on IBM mainframes System/370, System/390, zSeries, System z and compatible systems, including the Hercules emulator for personal computers. The following versions are known: ;Virtual Machine Facility/370 :VM/370, released in 1972, is a System/370 reimplementation of earlier CP/CMS operating system. ;VM/370 Basic System Extensions Program Product :VM/BSE (BSEPP) is an enhancement to VM/370 that adds support for more devices (such as 3370-type fixed-block-architecture DASD drives), improvements to the CMS environment (such as an improved editor), and some stability enhancements to CP. ;VM/370 System Extensions Program Product :VM/SE (SEPP) is an enhancement to VM/370 that includes the facilities of VM/BSE, as well as a few additional fixes and features. ;Virtual Machine/System Product :VM/SP, a milestone version, replaces VM/370, VM/BSE and VM/SE.

DOS/360 And Successors
Disk Operating System/360, also DOS/360, or simply DOS, is the discontinued first member of a sequence of operating systems for IBM System/360, System/370 and later mainframes. It was announced by IBM on the last day of 1964, and it was first delivered in June 1966. In its time, DOS/360 was the most widely used operating system in the world. DOS versions BOS/360 The Basic Operating System(BOS) was an early version of DOS and TOS which could provide usable functionality on a system with as little as 8 KB of main storage and one 2311 disk drive. TOS/360 TOS/360 (Tape Operating System/360, not a DOS as such and not so called) was an IBM operating system for the System/360, used in the early days around 1965 to support the System/360 Model 30 and similar platforms. TOS, as per the "Tape" in the name, required a tape drive. It shared most of the code base and some manuals with IBM's DOS/360. TOS went through 14 releases, and was discontinued when disks such as the IBM 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM System P
The IBM System p is a high-end line of RISC (Power)/UNIX-based servers. It was the successor of the RS/6000 line, and predecessor of the IBM Power Systems server series. History The previous RS/6000 line was originally a line of workstations and servers. The first System p server line was named the ''e''Server pSeries in 2000 as part of the e-Server branding initiative. In 2004, with the advent of the POWER5 processor, the server family was rebranded the ''e''Server p5. In 2005, following IBM's move to streamline its server and storage brands worldwide, and incorporating the "System" brand with the Systems Agenda, the family was again renamed to System p5. The System p5 now encompassed the IBM OpenPower product line. In 2007, after the introduction of the POWER6 processor models, the last rename under the System p brand dropped the p (numbered) designation. In April 2008, IBM announced a rebranding of the System p and its unification with the mid-range System i platform. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Z/OS
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.Starting with the earliest: * OS/VS2 Release 2 through Release 3.8 * MVS/System Extensions (MVS/SE) * MVS/System Product (MVS/SP) Version 1 * MVS/System Product Version 2 (MVS/Extended Architecture, MVS/XA) * MVS/System Product Version 3 (MVS/Enterprise Systems Architecture, MVS/ESA) * MVS/ESA SP Version 4 * MVS/ESA SP Version 5 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. Major characteristics z/OS supportsSome, e.g., TSO/E, are bundled with z/OS, others, e.g.,CICS, are separately priced. stable mainframe fac ...

System Administrator
A system administrator, or sysadmin, or admin is a person who is responsible for the upkeep, configuration, and reliable operation of computer systems, especially multi-user computers, such as servers. The system administrator seeks to ensure that the uptime, performance, resources, and security of the computers they manage meet the needs of the users, without exceeding a set budget when doing so. To meet these needs, a system administrator may acquire, install, or upgrade computer components and software; provide routine automation; maintain security policies; troubleshoot; train or supervise staff; or offer technical support for projects. Related fields Many organizations staff offer jobs related to system administration. In a larger company, these may all be separate positions within a computer support or Information Services (IS) department. In a smaller group they may be shared by a few sysadmins, or even a single person. * A database administrator (DBA) maintains a d ...

Microsoft Update Catalog
The Microsoft Update Catalog is a website that offers updates for computers running Windows 2000 SP3, Windows XP, and Windows Server 2003 and later operating systems including Windows 10. Scope Created by Microsoft, the service provides a list of updates for corporations to distribute over a network. Security updates are released once a month on the website, except in special circumstances; for instance, in the event of a widespread computer virus or worm, Microsoft releases a corresponding update as soon as possible. Gordon Mangione, Microsoft's Security Business & Technology Unit vice president (from 2004-03 to 2005-11), remarked: "Because the new services and technologies draw information and updates from a single source—the Microsoft Update catalog—and use a common polling engine (provided by the new Windows Update Agent), our customers will have a much more integrated and reliable update management process." Usage The latest iteration of the site was launched in August ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patch Tuesday
Patch Tuesday (also known as Update Tuesday) is an unofficial term used to refer to when Microsoft, Adobe, Oracle and others regularly release software patches for their software products. It is widely referred to in this way by the industry. Microsoft formalized Patch Tuesday in October 2003. Patch Tuesday is known within Microsoft also as the “B” release, to distinguish it from the “C” and “D” releases that occur in the third and fourth weeks of the month, respectively. Patch Tuesday occurs on the second Tuesday of each month in North America. Critical security updates are occasionally released outside of the normal Patch Tuesday cycle; these are known as "Out-of-band" releases. As far as the integrated Windows Update (WU) function is concerned, Patch Tuesday begins at 10:00 a.m. PST. Vulnerability information is immediately available in thSecurity Update Guide The updates show up in Download Center before they are added to WU, and the KB articles are unlock ...
