啓動監聽時發生下面的錯誤：
[oracle@wt ~]$ lsnrctl start

查看是否連接網絡，關閉防火牆。
修改：vim /etc/hosts再末尾添加ip地址及用戶名，例如10.0.0.1 jz
然後重啓網絡服務：[root@wt Desktop]# /etc/init.d/network restart
[root@wt Desktop]# ifup eth0
再重新啓動監聽：[oracle@wt ~]$ lsnrctl start
[oracle@wt ~]$ emctl start dbconsole //啓動EM工具時出現如下錯誤
Environment variable ORACLE_UNQNAME not defined. Please set ORACLE_UNQNAME to database unique name.
則：[oracle@wt ~]$ emca -config dbcontrol db -repos recreate //配置EM工具
Database SID: ora11g //ora11g是SID，可用show parameter instance_name 查詢
Listener port number: 1521 //監聽端口號
Listener ORACLE_HOME [ /u01/11g/product/11.2.0 ]: //郵箱，可直接enter略過
Password for SYS user: //密碼，一般以下三個密碼都是同一個

Password for SYSMAN user:
Do you wish to continue? [yes(Y)/no(N)]: y
然後再重新啓動：[oracle@wt ~]$ emctl start dbconsole
之後在客戶端上訪問：https://10.0.0.1:1158/em/console
出現端口後選擇:I Understand the risks--add exception--confirm security exception--添用戶名和密碼
瀏覽器漢化：edit---preferences---content--languages choose--select a language to add
