WebSphere Application Server Course Overview
WebSphere Application Server has several topology management options to meet your demands. You can create basic scenarios with single application server environments, or multiple application servers that are administered from a single point of control. Furthermore, you can extend your environment as needs change. These application servers can be clustered to provide scalable and highly available environments. WebSphere Application Server training uses IBM Installation Manager to manage the installation of the product. The IBM WebSphere Training Manager is a single installation tool that loads and installs product components from a structured collection of files known as a repository. IBM Installation Manager uses remote or local software repositories to install, modify, or update IBM software products, including WebSphere Application Server Training. Using the live repository, you can get an up-to-date list of available maintenance for your installed features and select exactly what maintenance to install. The Packaging Utility also allows you to create a central repository that is used for maintenance within the enterprise. This repository allows for greater administrative control and greater consistency across the installed users’ community. In a Liberty profile environment, installation can be done by using the Installation Manager, or a simplified installation can be performed by extracting an archive file. For z/OS, archive installation can be achieved by first installing Liberty using the IBM Installation Manager, then using the server packaging tool to produce a pax file.
