简介： 下面的步骤详细的说明了在Oracle 11gR2 RAC Database环境下使用emca配置集群dbconsole遇到的部分问题及解决的方法。1.数据库环境。Oracle Exadata Machine x4-2Oracle RAC Database 11.2.0.4.6 for Linux x86_64bit[root@dm01db01 ~]# uname -r2.6.39-400.126.1.el5uek2.使用EMCA创建EM。

下面的步骤详细的说明了在Oracle 11gR2 RAC Database环境下使用emca配置集群dbconsole遇到的部分问题及解决的方法。

1.数据库环境。
Oracle Exadata Machine x4-2
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：

CONFIG: Setting param: CONFIRMATION ANSWER value: no

    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。

EMCA: RepManager Fails With Password Verification Error ORA-28003 (文档 ID 779098.1)
修改时间:2013-10-23 类型:PROBLEM

In this Document

Solution
References


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 \

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 114930.1 can be used. For example:

SQL> alter profile default limit password_verify_function null;


5.禁用密码验证函数。

16 rows selected.

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。

存储 Oracle 关系型数据库
windows 使用 Oracle Database 19c
Oracle数据库是由美国Oracle Corporation（甲骨文公司）开发和提供的一种关系型数据库管理系统，它是一种强大的关系型数据库管理系统（RDBMS）。它使用表格（表）组织和存储数据，通过SQL语言进行数据管理。数据以表格形式存储，表之间可以建立关系。支持事务处理、多版本并发控制、安全性和权限控制。具有高可用性、容错性，支持分布式数据库和可扩展性。Oracle Corporation提供全面的支持和服务，使其成为企业级应用的首选数据库系统。
