Oracle重建企業管理器
1.首先建立監聽
[root@primary ~]# xhost +
access control disabled, clients can connect from any host
[root@primary ~]# su - Oracle
[oracle@primary ~]$ netca
批註：此處建立的監聽名字LISTENER，database_ID=orcl
查看企業管理器的網頁瀏覽方式所在目錄參考，如下：
[root@primary ~]# su - oracle
[oracle@primary ~]$ cd $ORACLE_HOME
[oracle@primary db_1]$ cd install
[oracle@primary install]$ more readme.txt
The following J2EE Applications have been deployed and are accessible at the URL
s listed below.
iSQL*Plus URL:
http://primary:5560/isqlplus
iSQL*Plus DBA URL:
http://primary:5560/isqlplus/dba
http://primary:1158/em
http://primary:1158/em
2.開啟資料庫
[oracle@primary install]$ sqlplus / as sysdba

SQL> select instance_name,status from V$instance;
INSTANCE_NAME STATUS
---------------- ------------
orcl OPEN
3.查看監聽狀態，必須是運行狀態
[oracle@primary install]$ lsnrctl status
LSNRCTL for Linux: Version 10.2.0.1.0 - Production on 17-JUN-2014 08:35:40

The command completed successfully
查看監聽連接埠號碼，如下：
[oracle@primary install]$ cd $ORACLE_HOME/network/admin/
[oracle@primary admin]$ ls
listener.ora samples shrept.lst tnsnames.ora
[oracle@primary admin]$ more listener.ora
# listener.ora Network Configuration File: /u01/oracle/db_1/network/admin/listen
er.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /u01/oracle/db_1)
(PROGRAM = extproc)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = primary)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
)
4.查看/etc/hosts裡邊的IP地址和主機名稱必須與實際一致
[root@primary ~]# hostname
primary
[root@primary ~]# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:0C:29:DA:7E:F0

[root@primary ~]# cat /etc/hosts

# that require network functionality will fail.

5.關閉企業管理器 emctl stop dbconsole
[oracle@primary ~]$ emctl stop dbconsole
TZ set to PRC
