1.数据库环境。

Oracle RAC Database 11.2.0.4.6 for Linux x86_64bit
[root@dm01db01 ~]# uname -r
2.6.39-400.126.1.el5uek
2.使用EMCA创建EM。
[root@dm01db01 ~]# su - oracle
[oracle@dm01db01 ~]$emca -config dbcontrol db -repos create -cluster
......
ORA-12514: TNS:listener does not currently kNow of service requested in connect descriptor
收到ORA-12514报错。
emca工具输出的日志被存放在$GRID_BASE/cfgtoollogs/emca目录下。
查看/u01/app/grid/cfgtoollogs/emca/emca_2014_06_18_10_26_50.log日志：

从最后面的日志可以看出，报ORA-12514错误的原因是不能通过SCAN LISTENER连接到ASM实例，说明ASM实例没有向SCAN LISTENER动态注册。
3.ASM实例向SCAN LISTENER动态注册。

| This document is being delivered to you via Oracle Support's Rapid Visibility (RaV) process and therefore has not been subject to an independent technical review. |
APPLIES TO:
Enterprise Manager Base Platform - Version 10.2.0.1 to 10.2.0.5 [Release 10.2]information in this document applies to any platform.
Checked for relevance on 22-Oct-2013
SYMPTOMS
While using EMCA to create DB Console repository,this fails with:
CONfig: ORA-28003: password verification for the specified password Failed
ORA-20003: Password should contain at least one \
ORA-20003: Password should contain at least one \
CAUSE
This is treated in internal BUG 4195090.
SOLUTION
a) disable the Password verification
b) Create the Repository
c) Enable the password verification.
Note: For disabling the password verification function,Note 114930.1can be used. For example:
sql> alter profile default limit password_verify_function null;
5.禁用密码验证函数。

************************ WARNING ************************
Management Repository has been placed in secure mode wherein Enterprise Manager data will be encrypted. The encryption key has been placed in the file: /u01/app/oracle/product/11.2.0.4/dbhome_1/dm01db01_tequdb/sysman/config/emkey.ora. Ensure this file is backed up as the encrypted data will become unusable if this file is lost.

FINISHED EMCA at Jun 18,2014 11:46:24 PM
成功创建EM。
7.重新启用密码验证函数。
sql> alter profile default limit password_verify_function VERIFY_FUNCTION_11G;
sql> select * from dba_profiles;
配置完成后检查是否能够正常的登录EM工具，另外还有两点需要注意：
1).emca是用操作系统oracle用户执行的。
2).不能使用IP地址访问EM工具，一定使用机器名访问，例如：https://dm01db01.tequ.com:1158/em
同时这篇文章也是对《构建最高可用Oracle数据库系统：Oracle 11gR2 RAC管理、维护与性能优化》的10.6.2小节的补充和完善。
