ORACLE OEM重建

一、Oracle OEM开启失败---环境变量ORACLE_UNQNAME未定义问题

登陆https://h1:1158/em 之后,看到数据库实例都是关闭的.启动不了 (1)查看dbconsole状态:emctl status dbconsole 显示:Environment variable ORACLE_UNQNAME not defined. Please define it. 解决方法： 在启动的时候先设置一下oracle_unqname set oracle_unqname=$ORACLE_SID 如果还是失败，在环境变量中添加： [oracle@h1 ~]$  vi ~/.bash_profile     在最后添加：export  ORACLE_UNQNAME=$ORACLE_SID    [oracle@h1 ~]$ source  ./bash_profile      使环境变量生效

 

2.emctl   start  dbconsole

如果还出现上述的错误：删除dbconsole重新配置

[oracle@h1 ~]$ emca -deconfig dbconsole db -repos drop STARTED EMCA at Mar 14, 2013 9:06:48 PM EM Configuration Assistant, Version 11.2.0.0.2 Production Copyright (c) 2003, 2005, Oracle.  All rights reserved. Enter the following information: Database SID: bitc Listener port number: 1522 Password for SYS user:  Password for SYSMAN user:  Do you wish to continue?

Mar 14, 2013 9:07:05 PM oracle.sysman.emcp.EMReposConfig invoke INFO: Dropping the EM repository (this may take a while) ...

3.如果删除失败，则旧数据清除

[oracle@h1 ~]$ sqlplus "/as SYSDBA" SQL*Plus: Release 11.2.0.1.0 Production on Thu Mar 14 21:08:54 2013 Copyright (c) 1982, 2009, Oracle.  All rights reserved. Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production With the Partitioning, OLAP, Data Mining and Real Application Testing options #(1)进入数据库删除dbconsole以前的用户，并且修改DBSNMP密码 SQL> alter user dbsnmp identified by manager;     #(2)删除早期DBCONSOLE创建的用户： sql>drop role MGMT_USER; sql>drop user MGMT_VIEW cascade; sql>drop user sysman cascade;   #(3)删除早期DBCONSOLE创建的对象： sql>drop PUBLIC SYNONYM MGMT_TARGET_BLACKOUTS; sql>drop public synonym SETEMVIEWUSERCONTEXT;

 

4. 重新创建DBCONSOLE：（如果是在windows下，要先到注册表删除DBCONSOLE的服务，重启电脑）

emca -config dbcontrol db -repos create

根据提示，先输入SID，再输入Y继续；

输入端口1521，输入SYS密码，输入DBSNMP密码，输入SYSMAN 密码，输入Y继续

完成。

 

5.emca 命令的日志在

/app/oracle/cfgtoollogs/emca/ORCL/

日志有两个，一个是概况，一个是明细

 

6.OEM开启
