Oracle重建企业管理器

1.首先创建监听[root@primary ~]# xhost +access control disabled, clients can connect from any host[root@primary ~]# su -

批注：此处创建的监听名字LISTENER，database_ID=orcl
查看企业管理器的网页浏览方式所在目录参考，，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:
:5560/isqlplus

iSQL*Plus DBA URL:
:5560/isqlplus/dba

:1158/em
:1158/em

2.打开数据库
[oracle@primary install]$ sqlplus / as sysdba

SQL*Plus: Release 10.2.0.1.0 - Production on Tue Jun 17 08:33:17 2014

Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production
With the Partitioning, OLAP and Data Mining options

SQL> select instance_name,status from V$instance;
INSTANCE_NAME STATUS
---------------- ------------
orcl OPEN

3.查看监听状态，必须是运行状态
[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

查看监听端口号，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里边的IP地址和主机名必须与实际一致
[root@primary ~]# hostname
primary
[root@primary ~]# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:0C:29:DA:7E:F0
inet addr:192.168.10.10 Bcast:192.168.10.255 Mask:255.255.255.0

[root@primary ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.

192.168.10.10 primary
#::1 localhost6.localdomain6 localhost6

5.关闭企业管理器 emctl stop dbconsole
[oracle@primary ~]$ emctl stop dbconsole
TZ set to PRC

6.删除em资料库 emca –repos drop
[oracle@primary ~]$ emca -repos drop
