Wsadmin
The wsadmin tool is a command shell for the purpose of performing systems administration on all the artifacts in an IBM WebSphere Application Server (WAS) cell. It gets its name from the name of the shell script that invokes this command shell. This command shell can execute connected to a WAS cell or completely disconnected from a WAS cell (local mode). The wsadmin tool can be used to execute scripts written in Jacl and Jython, or it can be used interactively to execute individual commands. These scripts and commands perform administrative tasks like application deployment, configuration changes and run-time monitoring and control of IBM WAS. History of WebSphere Application Server command shells The ''wscp'' stands for WebSphere Control Program. It was used in older versions of WAS like Version 4.0 and Version 3.5. The ''wsadmin'' command shell replaced ''wscp'' in WebSphere Application Server Version 5.0 and all subsequent versions. It can perform almost all of the tasks ...

Jython
Jython is an implementation of the Python (programming language), Python programming language designed to run on the Java (programming language), Java platform. It was known as JPython until 1999. Overview Jython programs can import and use any Java class. Except for some standard modules, Jython programs use Java classes instead of Python modules. Jython includes almost all of the modules in the standard Python (programming language), Python programming language distribution, lacking only some of the modules implemented originally in C (programming language), C. For example, a user interface in Jython could be written with Swing (Java), Swing, Abstract Window Toolkit, AWT or Standard Widget Toolkit, SWT. Jython compiles Python source code to Java bytecode (an intermediate language) either on demand or statically. History Jython was initially created in late 1997 to replace C (programming language), C with Java (programming language), Java for performance-intensive code accessed ...

Command Shell
An operating system shell is a computer program that provides relatively broad and direct access to the system on which it runs. The term ''shell'' refers to how it is a relatively thin layer around an operating system. A shell is generally a command-line interface (CLI) program although some graphical user interface (GUI) programs are arguably classified as shells too. Overview Operating systems provide various services to their users, including file management, process management (running and terminating applications), batch processing, and operating system monitoring and configuration. Most operating system shells are not ''direct'' interfaces to the underlying kernel, even if a shell communicates with the user via peripheral devices attached to the computer directly. Shells are actually special applications that use the kernel API in just the same way as it is used by other application programs. A shell manages the user–system interaction by prompting users ...

IBM WebSphere Application Server
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 (software platform), Java-based web applications. It is the flagship product within IBM's IBM WebSphere, 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. Architecture WebSphere Application Server (WAS) is built using open standards such as Java Platform, Enterprise Edition, Java EE, XML, and Web service, Web Services. It runs on the following platforms: Windows, AIX, Linux, Solaris, IBM i and WebSphere Application Server for z/OS, z/OS. Beginning with Version 6.1 and now into Version 9.0, the open standard specifications are aligned and common across all the platforms. Platform exploitation, to t ...

Shell Script
A shell script is a computer program designed to be run by a Unix shell, a command-line interpreter. The various dialects of shell scripts are considered to be command languages. Typical operations performed by shell scripts include file manipulation, program execution, and printing text. A script which sets up the environment, runs the program, and does any necessary cleanup or logging, is called a wrapper. The term is also used more generally to mean the automated mode of running an operating system shell; each operating system uses a particular name for these functions including batch files (MSDos-Win95 stream, OS/2), command procedures (VMS), and shell scripts (Windows NT stream and third-party derivatives like 4NT—article is at cmd.exe), and mainframe operating systems are associated with a number of terms. Shells commonly present in Unix and Unix-like systems include the Korn shell, the Bourne shell, and GNU Bash. While a Unix operating system may have a different ...

Transmission Control Protocol
The Transmission Control Protocol (TCP) is one of the main communications protocol, protocols of the Internet protocol suite. It originated in the initial network implementation in which it complemented the Internet Protocol (IP). Therefore, the entire suite is commonly referred to as TCP/IP. TCP provides reliability (computer networking), reliable, ordered, and error detection and correction, error-checked delivery of a reliable byte stream, stream of octet (computing), octets (bytes) between applications running on hosts communicating via an IP network. Major internet applications such as the World Wide Web, email, remote administration, and file transfer rely on TCP, which is part of the transport layer of the TCP/IP suite. Transport Layer Security, SSL/TLS often runs on top of TCP. TCP is Connection-oriented communication, connection-oriented, meaning that sender and receiver firstly need to establish a connection based on agreed parameters; they do this through three-way Ha ...

LPAR
A logical partition (LPAR) is a subset of a computer's hardware resources, virtualized as a separate computer. In effect, a physical machine can be partitioned into multiple logical partitions, each hosting a separate instance of an operating system. History IBM developed the concept of hypervisors (virtual machines in CP-40 and CP-67) and in 1972 provided it for the S/370 as Virtual Machine Facility/370. IBM introduced the Start Interpretive Execution (SIE) instruction (designed specifically for the execution of virtual machines) in 1983 as part of 370-XA architecture on the IBM 3081, as well as VM/XA versions of VM to exploit it. Amdahl Corporation's Multiple Domain Facility (MDF) was introduced in 1982. IBM introduced its functionally similar PR/SM in 1988, implemented on its ESA/370 architecture released that year with the IBM 3090 processors. PR/SM (Processor Resource/System Manager) is a type-1 Hypervisor (a virtual machine monitor) that allows multiple logica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java (programming Language)
Java is a High-level programming language, high-level, General-purpose programming language, general-purpose, Memory safety, memory-safe, object-oriented programming, object-oriented programming language. It is intended to let programmers ''write once, run anywhere'' (Write once, run anywhere, WORA), meaning that compiler, compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to Java bytecode, bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax (programming languages), syntax of Java is similar to C (programming language), C and C++, but has fewer low-level programming language, low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as Reflective programming, reflection and runtime code modification) that are typically not available in traditional compiled languages. Java gained popularity sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java EE
Jakarta EE, formerly Java Platform, Enterprise Edition (Java EE) and Java 2 Platform, Enterprise Edition (J2EE), is a set of specifications, extending Java SE with specifications for enterprise features such as distributed computing and web services. Jakarta EE applications are run on reference runtimes, which can be microservices or application servers, which handle transactions, security, scalability, concurrency and management of the components they are deploying. Jakarta EE is defined by its specification. The specification defines APIs (application programming interface) and their interactions. As with other Java Community Process specifications, providers must meet certain conformance requirements in order to declare their products as ''Jakarta EE compliant''. Examples of contexts in which Jakarta EE referencing runtimes are used are: e-commerce, accounting, banking information systems. History The platform created by Sun Microsystems was known as ''Java 2 Platform, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C (programming Language)
C (''pronounced'' '' – like the letter c'') is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted Central processing unit, CPUs. It has found lasting use in operating systems code (especially in Kernel (operating system), kernels), device drivers, and protocol stacks, but its use in application software has been decreasing. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the most widely used programming langu ...
