The wsadmin is a powerful tool of the IBM WebSphere Application Server (WAS). The use of wsadmin tool was widely increased with the IBM WAS version 5.0. The WAS wsadmin tool is used to execute scripts written in JACL and Jython. These scripts are written to automate the tasks like installation, application deployment, configuration changes and run-time operations etc. of IBM WAS. The wscp stands for WebSphere Control Program. It was used in older versions of WebSphere Application Server like Version 4.0 and Version 3.5. It was used for configuration as well as run-time operations. Like wscp, the wsadmin is also used for configuration, application deployment and all kind of server operations. The wsadmin tool can perform every task which can be done through Graphical User Interface (GUI). It is used with WebSphere Application Server Version 5.0 - 7.0 It is very difficult to convert wscp scripts to wsadmin scripts automatically and vice-versa.
