This is a very common port, which is used by many other webservers, if we have installed it, we 'd better modify it to avoid conflicts. If we don't use it, we 'd better not disable the XDB service: An XDB service is added to oracle9i and started on port 8080, the following operations can be removed. Edit $ ORACLE_HOME/dbs/initSID. remove the following lines from the ora file: dispatchers = & apos; (PROTOCOL = TCP) (SERVICE = XDB) & apos; Use sys to access sqlplus, stop the oracle server, and run: create spfile from pfile; startup is the above operation in linux. If it is relatively simple in windows, directly edit the init under oracle \ admin \ SID \ pfile. ora, remove the corresponding row, and restart oracle.
