Installing WebSphere® Application Server
The IBM® WebSphere® Application Server installation consists of two parts: IBM® Installation Manager and the WebSphere® Application Server itself.
IBM® Installation Manager
The IBM® Installation Manager is used to assist in the installation of WebSphere® Application Server and the corresponding fixpacks. You can go to IBM Installation Manager Knowledge Center for more details.
IBM® WebSphere® Application Server
Since the HCL Docs components are WebSphere-based applications, you must install WebSphere® Application Server, create profiles and servers for each of these applications: Editor Application, Editor Proxy, Document Format Conversion Application, and Viewer Application.
