tomcat和oracle启动时发生8080端口冲突,怎样通过修改oracle默认端口使之不冲突?

1、在oracle 安装文件夹下面搜索一下文件中含有8080 的文件，里面有个readme讲怎么改端口
2、
SQL> call dbms_xdb.cfg_update(updateXML(dbms_xdb.cfg_get(),
2 '/xdbconfig/sysconfig/protocolconfig/httpconfig/http-port/text()',8081))
3 /
SQL> commit;

Commit complete.

SQL> exec dbms_xdb.cfg_refresh;

[oracle@test11 oracle]$ sqlplus /nolog
