The key XML DB technologies can be grouped into two major classes - a XMLType that provides a native XML storage and retrieval capability strongly integrated with SQL, and a XML Repository that provides foldering, access control, versioning etc. for XML resources. Users view and manage XML objects like files and schemas in the XML Repository as a hierarchy of folders. This repository aspect of XML DB involves access through standard protocols such as HTTP/WebDAV and FTP. These servers will bind to ports 8080 and 2100 respectively by default.
DBA's will sometimes wonder why their Web Server, that always used to work, has all of the sudden been hijacked after installing Oracle9i and creating a database using DBCA. After some research, they attempt to shutdown the Oracle TNS listener and notice that the port in question (mostly 8080) is no longer being utilized. Unfortunately, there is little to tell the DBA that these ports are going to be used until they find out the hard way: When the database starts and steals the ports away from another process that hasn't yet started or when the other process errors and/or is unreachable.
