利用Oracle Enterprise Manager Cloud Control 12c创建DataGuard Standby

作者: Maclean Liu, post on January 21st, 2012

Oracle Enterprise Manager Cloud Control 12c在对数据库管理(Database Management)的各个方面相比11g Grid Control都有所增强， 具体可以参考《New Features In Oracle Enterprise Manager Cloud Control 12c》。

 

下面我们利用 EM Cloud Control 12c来创建一个物理备库 physical Standby :

 

1. 首先确保Primary Database处于归档模式下 archivelog mode下 ， 且EM至少拥有2个以上的host target， 确认在standby host上已安装与primary database 版本一致的数据库软件ORACLE_HOME

 

2. 正式创建 physical standby

 

登录OEM界面，点击target=>Database=>选择你要创建standby的数据库名=> 点击Availability => Add Standby Database:

Oracle Enterprise Manager 12c 新特性:实时Real-Time Addm

作者: Maclean Liu, post on October 19th, 2011

在Oracle Enterprise Manager 12c中引入了Real-Time addm的新特性。 DBA可以直接从EM界面上启动实时ADDM(Automatic Database Diagnostic Monitor )信息收集， 也叫做Emergency ADDM。

 

“Emergency ADDM adds performance diagnostics for databases suffering from severe performance problems. Real-time ADDM. You can connect to the database and investigate what is going on when you cannot connect to the database because it is hanging on“

快速部署Enterprise Manager Cloud Control 12c(12.1) Agent

作者: Maclean Liu, post on October 18th, 2011
install_agent_2

在<OEL 5上快速部署Enterprise Manager Cloud Control 12c(12.1)>中我介绍了如何安装配置Oracle Enterprise Manager Cloud Control 12c(12.1) Server ，我们知道光有EM Server而不部署Agent是无法发挥其管理特性的。

接下来我们会再次通过实践了解Em 12c(12.1)中部署Agent代理程序的过程，整个过程和10g/11g Grid Control中的Deploy Agent有较大的区别。

 

这里我们要注意一点，OMS 12c(12.1) 只能和12.1 的Agent 代理程序配合工作，而不能使用之前任何版本的Agent。“Enterprise Manager Cloud Control can communicate only with Oracle Management Agent 12c and not with any other earlier release of the Management Agent. You can not configure your exising Agents to . . . → Read More: 快速部署Enterprise Manager Cloud Control 12c(12.1) Agent

Oracle Database 12c(12.1) Beta已经开始内部测试

作者: Maclean Liu, post on October 15th, 2011
12c_1

据悉Oracle Database 12.1 (12c)这个未来版本的Beta版已经开始在Oracle内部大规模测试，见下图:

 

 

12c的官方文档已经在Oracle内部网络可访问，包括Concepts、Reference和SQL Tuning Guide等，但似乎还没有12c 12.1 New Feature的文档。

以下为12.1 12c使用DBUA图形化工具升级数据库的界面，可以看到图形化界面的美学风格和11gR2没有太大的差别。

 

 

这些文档在外部尚不能访问，但是12c Release 1 (12.1) Beta的文档主页已经建立:
