在啟動tomcat的時候提示8080端口被占用，后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臺機器上，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 -i|grep 8080

[root@olivenan root]# netstat -tln|grep 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"
