EM12c創(chuàng)建備庫時找不到agent備庫主機(jī)

現(xiàn)象：

在用EM12cR4創(chuàng)建備庫時，不能搜索到備庫的主機(jī)，但備庫主機(jī)已經(jīng)在主機(jī)列表中存在，而且備庫主機(jī)上的agent也已經(jīng)安裝并狀態(tài)正常。

原因：

在agent端插件目錄缺少所需要的插件

解決：

安裝代理插件

1. 登錄EM12c

2. 在菜單 安裝-> Extensibility -Plug-ins>

3. 在Plug-ins頁，選擇 Database -> Oracle Database

4. 點(diǎn)擊 Deploy On -> Management Agent

5. 點(diǎn)Continue為列出的主機(jī)添加agent插件

參考文檔：

修改時間:2012-12-15類型:PROBLEM

In this Document

APPLIES TO:

Enterprise Manager Base Platform - Version 12.1.0.2.0 to 12.1.0.2.0 [Release 12.1]
Information in this document applies to any platform.

SYMPTOMS

Creation of Standby Database from OEM 12.1.0.2 fails with the following error:

The grid control database plug-in must be deployed on the agent monitoring the select host.

CAUSE

Plugins directory at the agent side does not have the required plugin

drwxr-xr-x 9 oracle oracle 4096 Nov 29 14:05 oracle.sysman.emas.discovery.plugin_12.1.0.3.0

oracle.sysman.db.agent.plugin is missing which is required for monitoring.

SOLUTION

to create standby database on a new server, we still need a plugin to be deployed on the agent.

Please do the following steps:

1. Login to 12C Cloud Control
2. Navigate to Setup --> Extensibility
3. Select the option Plugins
4. Expand the option "Databases"
5. Select "Oracle Database"
6. Expand the option "Deploy On" and Choose "Management Agent"
7. In the page displayed, Click on "Add" to add the Agent on which plugin needs to be deployed (On the server where standby is created).
8. After adding the agent name, it will run the prerequisite check, after successful completion of prerequisite check, click on Next.
9. A Confirmation message about deployment of database plugin on Management Agent will be displayed.

This will complete the deployment of database plugin to management agent.

Once this is done, create standby database.
