将oracle与tomcat、jboss等其它占用8080端口的服务器安装在一台机器上，会出现8080端口被占用的错误。
一、首先检查8080端口的使用情况
[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)
发现8080端口被oracle使用，注意lsof命令参数的使用。
[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、解决方法一
查找解决方法
将*.dispatchers='(PROTOCOL=TCP) (SERVICE=orclXDB)'
修改为#*.dispatchers='(PROTOCOL=TCP) (SERVICE=orclXDB)'
[oracle@olivenan dbs]$ sqlplus "/as sysdba"
