Fusion Middleware products are riddled with configuration preference options and perhaps that is what makes these tools so great. Another option that is available to you during the Oracle BI installation process is the ability to modify default ports that are assigned to Oracle BI and Fusion Middleware for accessing their applications. For example, if you wanted to change the default port for Oracle BI Presentation Services, 9500 to 8000, you could do that at the Port Management step in the installation wizard. This is shown in the following screenshot, which you saw in Chapter 3, Installing on Windows Server 2012 during the installation by changing the Port Range Starting Port to 8000 instead of 9500 as you did during the installation. Please note that desires of modifying ports as a means to an end after the Oracle install completes should be redirected to an HTTP tier configuration instead of Oracle BI or WebLogic configurations:
Note
Post-installation modifications of ports for Oracle BI are only important in two situations: when running multiple instances of Oracle BI or another application on the same server or when you plan to have no multi-tier server architecture as part of your Oracle BI architecture design. Otherwise, you would always have a web tier HTTP server sitting above your Oracle BI and Fusion middleware servers from which you are in a much better management position and have greater flexibility in assigning ports, virtual IP addresses, and DNS names to access your Oracle BI applications from. Previous versions of Oracle BI 11g had the concept of static ports configuration, but this option is not available in Oracle BI 12c.
Keeping with the default options should be rather easy as most Oracle BI implementations should be a single Oracle BI tenant on the server on which it is installed. Therefore there should be no port conflicts. If you wanted to change the port for the Oracle BI /analytics application to port 80, (which is the default web port that requires no port number to be entered for the URL) in the browser address bar, then you shouldn't use this option, but rather a web tier server to handle that proxy for you. Compatible Web Tier servers for Oracle BI are IIS, Apache, or Oracle HTTP servers, to name a few.
