在啟動tomcat的時候提示8080端口被占用，後來經過查找發現如下結論：
將Oracle與tomcat、jboss等其它占用8080端口的服務器安裝在一台機器上，會出現8080端口被占用的錯誤。
一、首先檢查8080端口的使用情況
[root@olivenan root]# lsof -i :8080 -n
COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME
tnslsnr 1031 oracle 12u IPv4 2013 TCP *:webcache (LISTEN)
[root@olivenan root]# lsof -i tcp:8080 -n
COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME
tnslsnr 1031 oracle 12u IPv4 2013 TCP *:webcache (LISTEN)
發現8080端口被oracle使用，注意lsof命令參數的使用。
[root@olivenan root]# lsof -i udp:8080 -n
[root@olivenan root]# lsof -igrep 8080
[root@olivenan root]# netstat -tlngrep 8080
tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN
[root@olivenan root]#
二、解決方法一
查找解決方法
將*.dispatchers='(PROTOCOL=TCP) (SERVICE=orclXDB)'
修改為#*.dispatchers='(PROTOCOL=TCP) (SERVICE=orclXDB)'
[oracle@olivenan dbs]$ sqlplus "/as sysdba"

SQL> exit
[root@olivenan root]# lsof -i :8080 -n
[root@olivenan root]
結果端口8080停止被占用
三、解決方法二
將XMLDB的端口轉換為其它端口，此例轉換為8082
SQL> call dbms_xdb.cfg_update(updateXML(dbms_xdb.cfg_get(), '/xdbconfig/sysconfig/protocolconfig/httpconfig/http-port/text
()', 8082));
Call completed.
SQL> exec dbms_xdb.cfg_refresh;
PL/SQL procedure successfully completed.
將FTP端口由2100轉換為2111
SQL> call dbms_xdb.cfg_update(updateXML(dbms_xdb.cfg_get(), '/xdbconfig/sysconfig/protocolconfig/ftpconfig/ftp-port/text
()',2111));
Call completed.
SQL> commit;
Commit complete.
SQL> exec dbms_xdb.cfg_refresh;
