Oracle 11gRAC Enterprises Manager (OEM)配置

记录一下简单的操作

1、先确保一下帐号没有被锁

select * from dba_users where username in ('SYS','SYSTEM','SYSMAN','DBSNMP','ASMSNMP');

如果没有asmsnmp帐号,则创建一个并授权
create user asmsnmp identified by oracle;
grant sysdba to asmsnmp;

 

2、如果有帐号锁定,则给解锁

alter user sysman account unlock;

 

3、确保每个节点的orapwSID文件正确。

db2>orapwd file=orapwd$SID force=y

 

4、确保节点间的ssh互信正常。

 

5、确保每节点的监听程序正常,监听程序路径为统一路径(后续会需要填写监听程序路径,如果不一致可能会有问题),比如有部分集群的监听,有些节点监听在grid帐号目录下启动,有些在oracle帐号主目录下启动。

 

6、然后在任意一节点oracle帐号下开始配置EM,

 

7、启动每个节点上的dbconsole

 

使用如下命令进行配置并输入相关密码等信息,以下是一次完整的配置过程记录

然后在各个节点上使用oracle账户把dbconsole起起来即可

emctl  start  dbconsolel

 

最后在浏览器中输入https://节点ip:1158/em  然后输入sys帐号及密码即可登录。
