Environment variable Oracle_UNQNAME not defined. Please set ORACLE_UNQNAME to database unique name.

其实就是em的问题重新配置emca即可。以后注意之前设置好ORACLE_UNQNAME 。

总结收藏:

1,修改DBSNMP密码:

重新配置DBCONSOLE,需要输入DBSNMP密码,但任何密码都会显示错误,需要预先修改。

alter user dbsnmp identified by xxx; 

2,删除早期DBCONSOLE创建的用户:

drop role MGMT_USER;
drop user MGMT_VIEW cascade;
drop user sysman cascade; 

3,删除早期DBCONSOLE创建的对象:

drop PUBLIC SYNONYM MGMT_TARGET_BLACKOUTS;
drop public synonym SETEMVIEWUSERCONTEXT;
drop public synonym MGMT_AVAILABILITY;
drop public synonym MGMT_CURRENT_AVAILABILITY;
drop public synonym MGMT_SEVERITY_OBJ; 

4,重新创建DBCONSOLE:(如果是在windows下,要先到注册表删除DBCONSOLE(HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/OracleDBconsole)的服务,重启电脑)

$emca -config dbcontrol db -repos create;

如果此命令还是失败,,可直接利用重建命令:

$emca -config dbcontrol db -repos recreate; 

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,检查状态

emctl status dbconsole;

附emca常用命令:

创建一个EM资料库

emca -repos create

 

重建一个EM资料库

emca -repos recreate

 

删除一个EM资料库

emca -repos drop

 

配置数据库的 Database Control

emca -config dbcontrol db

 

删除数据库的 Database Control配置

emca -deconfig dbcontrol db

 

重新配置db control的端口,默认端口在1158

emca -reconfig ports

emca -reconfig ports -dbcontrol_http_port 1160

emca -reconfig ports -agent_port 3940

 

先设置ORACLE_SID环境变量后,启动EM console服务

emctl start dbconsole

先设置ORACLE_SID环境变量后,停止EM console服务

emctl stop dbconsole

先设置ORACLE_SID环境变量后,查看EM console服务的状态

 

 

配置dbconsole的步骤

emca -repos create

emca -config dbcontrol db

emctl start dbconsole

 

重新配置dbconsole的步骤

emca -repos drop

emca -repos create

emca -config dbcontrol db
