Load Running 101 (Multi user access)
Load running is a process used when multiple users are accessing a single server; it is used to relieve the burden of load on the server. This process is supported by load runner software. Program running is a more common description for the said software program. Use of computers commonly involve overlapping of certain computer program and task performed by the computer. Computer programs are a sequence of commands encoded for a computer to perform particular tasks.
Execution of the program instructions makes the program functional with the help of the central processor. Executed files follow a format on which the central processor could read it, the algorithm. Most users perform two or more programs at the same time; in this case the term of having two or more programs at the same time is referred as multitasking. In multitasking the process capability of the processor for executed program is lessened and performance degraded. But some operating systems are already capable of running programs simultaneously. It is made possible through process scheduling, a software device that switches the Central Processing Unit among the processes so that the user could interact with each running program.
In interconnected computers where many users are involved which are connected into a common server, the multitasking method within the users becomes burden for the server in hand. To resolve this problem numerous number of load running software were developed. Some of these are Jmeter, Webload, and Facilitar.
Loading utility is used to load accessible data files for instance sequential or text files into the database. Typically, the source format of the data file and desired database file structures are precise to the utility, which then automatically reformats the data and stores it in the database loading process, prearranged with the existing source and target database storage description. Load manager performs all the operations linked with the removal and loading of data into the warehouse. These operations contain simple transformations of the data to set up the data for entry into the warehouse. The size and complexity of this part will vary between data warehouse and maybe constructed using a permutation of vendor data loading tools and custom built programs. Warehouse Manager performs all operations associated with the management of the data in the warehouse.
Load running software enables the user to group the programs he using with just a few clicks, switch from one working project to another easily, and hides (and unhide) unnecessary pop outs and distracting window icons.
But amongst the most familiar load running software out there in the market is the Control Runner. It started its first release during June of 1995. As a Windows 3 shell replacement program. By the following year in October, its succeeding version came out of the market; it has added Launch Menu and Multiple file import in its arsenal, along with proper online documentation and installation routines, executable on 32 bit. As another year has gone by, they have developed another version with new innovations such as; additional configuration options, tray icons with options (Desktop icons, Select Printer, Change resolution, Screen saver, Launch Menu, Hidden Windows, and Control Panel). As of September of this year, Control runner had 16 versions since September of 1997. Enhancements are as follows; Incompatibility issues between MomShell (older version of Control Runner) and OpenGL library based programs were resolved, Support for Windows XP and Windows 2000 added, Virtual items complete support, Calendar Dialog resizing problems on Windows XP systems solved, Problems on programs that stops working after evaluation period were fixed, processing shortcuts links on the Program Configuration Dialog are good to go, Windows Vista compatibility, MSI style shortcuts are handled correctly, 32 bit icons processes are changed, Execution of programs launched were confirmed, Enhances the processing of program item icons on the program configuration dialog, improved repainting speed, Windows 7 compatible, Better management of web targets.
Control runner is a user friendly software; it enables the user easy access to the information needed thru Control runner icon on the system, creates a group for frequently visited sites, important web-sites and an easy access to needed links for web-sites. A direct and easy to manage start menu, and absolute control over your Windows software. Time is valuable, making Control runner an important from time conscious users. It provides maximum efficiency of time in searching and rearranging window documents.
Another load running software is the Load runner; the software works by having virtual users which will take place of the real users who operates the client software. Unlike other workstations which allow only one user of a client, Load runner enables the function of a thousand virtual users. After which is sending request with the use of an HTTP protocol to a web server. To create a load from a virtual user, requests are processed through Load Generators. These generators are controlled by a Controller program which is responsible for controlling load test runs based on scenarios calling up compiled scripts and related Run time settings. Then, with the use of the Virtual user script generator a script is then crafted. This script is a C-language script code generated which virtual users encode by capturing network traffic within internet servers and clients.
In general, this load running software is very helpful tools for heavy duty internet and program users. It helps them perform their tasks in an efficient manner, minimizing slack time and reducing arising errors. Fast switching of one program to another is one of the advantages of this scheme; fast switching enables the user to immediately shift from the other work to the other diminishing any possible error from slow program switching. Source code generation is also an aspect in load running, source codes are often encoded by computer programmers. Written in a programming language that typically follows one of the two main paradigms; declarative or imperative programming. These codes could also be converted into an executable file by a certain compiler and then processed by the central processing unit.
