contents 【相关文章:读核日记声明】

oracle introduced the xml database in release 9i. along with this new feature, oracle continues the practice of incorporating new, barely documented port assignments that often leave the dba to search endlessly for possible configuration file(s) that define these port assignments. well, when it comes to searching for where these port numbers related to xml db are defined, you will not find them on the file system, but rather inside the database. this article will attempt to unravel some of the mysteries on managing port assignments related to oracle xml db.【扩展信息:GCC安装参考】

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.
dbas 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 hasnt yet started or when the other process errors and/or is unreachable.
