After we have decided the deployment plan in terms of the number of servers, we will look at the prerequisites before we check the system requirements.
There are four important prerequisites:
Web Server preparation: We learned the role of Web Server in Chapter 1 and we need to ensure that Web Server is installed as per the deployment plan. The default Web Server is Oracle HTTP Server.
WebApp Server preparation: We have learned that there are a few products of Oracle EPM, along with Hyperion Planning, that would need WebApp Server and we need to install WebLogic on the servers or machines in accordance with our deployment plan.
