If you are running the Oracle Web Server component, it is recommended that you install Oracle and the Oracle Web Server component on a dedicated database server and have a separate server for SmartPlant Foundation. This configuration is recommended because the IIS component, which is required by the SmartPlant Foundation server software, and the Oracle Web Server component use the same port number (port 80) by default. When the database server and the SmartPlant Foundation application server are on different computers, both the Oracle Web Server component and the IIS software component can use the same default port number of 80.
Beginning with Windows 10 and Oracle 12.1.0.2, Microsoft and Oracle will enforce the
Internet Host Table Specification RFC 952 which mandates that component hostname labels
may contain only alphanumeric characters. Hostnames using underscores (‘_’) are not
allowed. For more information, refer to Oracle Support Articles 1603775.1 and 1957895.1
and Microsoft KB 101785.
If you choose to have only one server act as both the database and application server
and you have the Oracle Web Server component and IIS software installed, the port
number for one of the components must be a value other than port 80. If both these
components use the default port number of 80, SmartPlant Foundation will have communication problems. The Oracle Web Component is not required for SmartPlant Foundation.
