IBM 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 data that is intended to be used to modify an existing software resource such as a computer program, program or a computer file, file, often to fix software bug, bugs and security vulnerability, security vulnerabilities. A patch may be created to improve functionality, usability, or Computer performance, performance. A patch is typically provided by a vendor for updating the software that they provide. A patch may be created manually, but commonly it is created via a tool that compares two versions of the resource and generates data that can be used to transform one to the other. Typically, a patch needs to be applied to the specific version of the resource it is intended to modify, although there are exceptions. Some patching tools can detect the version of the existing resource and apply the appropriate patch, even if it supports multiple versions. As more patches are released, their cumulative size can grow significantly, sometimes exceeding the size of the resource ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-availability Cluster
In computing, high-availability clusters (HA clusters) or fail-over clusters are groups of computers that support server applications that can be reliably utilized with a minimum amount of down-time. They operate by using high availability software to harness redundant computers in groups or clusters that provide continued service when system components fail. Without clustering, if a server running a particular application crashes, the application will be unavailable until the crashed server is fixed. HA clustering remedies this situation by detecting hardware/software faults, and immediately restarting the application on another system without requiring administrative intervention, a process known as failover. As part of this process, clustering software may configure the node before starting the application on it. For example, appropriate file systems may need to be imported and mounted, network hardware may have to be configured, and some supporting applications may nee ...

Windows Update
Windows Update is a Microsoft service for the Windows 9x and Windows NT families of the Microsoft Windows operating system, which automates downloading and installing Microsoft Windows software updates over the Internet. The service delivers software updates for Windows, as well as the various Microsoft Antivirus software, antivirus products, including Windows Defender and Microsoft Security Essentials. Since its inception, Microsoft has introduced two extensions of the service: Microsoft Update and Windows Update for Business. The former expands the core service to include other Microsoft products, such as Microsoft Office and Microsoft Expression Studio. The latter is available to business editions of Windows 10 and permits postponing updates or receiving updates only after they have undergone rigorous testing. As the service has evolved over the years, so has its client software. For a decade, the primary client component of the service was the Windows Update web app that coul ...

Windows Server Update Services
Windows Server Update Services (WSUS), previously known as Software Update Services (SUS), is a computer program and network service developed by Microsoft Corporation that enables administrators to manage the distribution of updates and hotfixes released for Microsoft products to computers in a corporate environment. WSUS downloads these updates from the Microsoft Update website and then distributes them to computers on a network. WSUS is an integral component of Windows Server. History The first version of WSUS was known as Software Update Services (SUS). At first, it only delivered hotfixes and patches for Microsoft operating systems. SUS ran on a Windows Server operating system and downloaded updates for the specified versions of Windows from the remote Windows Update site, which is operated by Microsoft. Clients could then download updates from this internal server, rather than connecting directly to Windows Update. Support for SUS by Microsoft was originally planned t ...

Software Updater
In several Linux operating systems, the Software Updater program updates installed software and their associated packages with important software updates for security or with recommended patches. It also informs users when updates are available, listing them in alphabetical order for users to choose which updates to install, if any. It was originally written for Ubuntu, although it is now part of other APT-based systems. The application was originally called ''Update Manager''; it was announced in May 2012 that starting with Ubuntu 12.10 the name would change to ''Software Updater'' to better describe its functions. Technically the rename only affected the GUI; the name of the APT package containing the application, the executable file itself, and internally the software itself, still use the name update-manager. The Software Updater cannot uninstall updates, although this can be accomplished by other package managers such as Ubuntu Software Center and more technically adv ...

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. 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. Pacific Time. 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 unlocked later.

Microsoft Update Catalog
The Microsoft Update Catalog is a website created by Microsoft that provides a list of patches, drivers and software for corporations to distribute over a network. Scope 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 2007, and at the time, only worked in the web browser Internet Explorer, version 6 and version 7. Before using the catalog, the ...

System Administrator
An IT administrator, system administrator, 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 Server (computing), servers. The system administrator seeks to ensure that the uptime, Computer performance, performance, System resource, resources, and Computer security, security of the computers they manage meet the needs of the User (computing), 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 ...

SMP/E
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 ...

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 ...

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 that originated in the 1960s and is 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 ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
