重新配置Oracle EM

最近在倒腾Oracle，把EM给搞挂了，害我又得重新弄半天。

1. emca -deconfig dbcontrol db

进行查询

2. emca -repos drop

删除repository

如果删除错误，手动执行删除相关用户和权限

SQL> drop user sysman cascade;

SQL> drop role MGMT_USER;

SQL> drop user MGMT_VIEW cascade;

SQL> drop public synonym MGMT_TARGET_BLACKOUTS;

SQL> drop public synonym SETEMVIEWUSERCONTEXT;

3. emca -config dbcontrol db -repos create

重新创建Database Control

期间需要输入用户DBSNMP和SYSMAN的密码，我也不清楚它们的初始密码是什么。只有来自己改

SQL> alter user dbsnmp identified by dbsnmp;

备份并修改%oracle_home%/sysman/config/emoms.properties

oracle.sysman.eml.mntr.emdRepPwd=sysman
oracle.sysman.eml.mntr.emdRepPwdEncrypted=FALSE

备份并修改%oracle_home%/sysman/emd/targets.xml

<Property NAME="UserName" VALUE="DBSNMP" ENCRYPTED="FALSE"/>

<Property NAME="password" VALUE="dbsnmp" ENCRYPTED="FALSE"/>

附上几个有用的参考
