Oracle OEM13c 如何卸载

基本概念：Oracle Enterprise Manager Cloud Control-EMCC是OEM家族的优秀产品，日常运维过程中由于OEM升级或者安装失败等场景需要卸载OEM。



EMCC的主要组件：

Oracle Management Repository (OMR)
Oracle Management Service (OMS)
包含特定于目标的插件的 Oracle Management Agent（OMA 或代理）
Cloud Control Console
Oracle Management Agent 在主机上运行，并搜集有关这些主机环境的度量数据，以及使 用插件来监视可用性、配置和性能并管理在主机上运行的目标。这些代理可与 Oracle Management Service 进行通信，以便上载它们及其插件所收集的度量数据。然后，OMS 会将其收集的数据存储在 Oracle Management Repository 中，OMS 可以从中访问这些数 据以执行自动和手动报告和监视。OMS 还可以与代理进行通信，以便组织对所监视目标 的管理。除了协调代理之外，OMS 还可运行 Cloud Control Console Web 页面，管理员 和用户可使用这些页面来监视和管理 Cloud Control 通过代理及其插件可见的计算环境并 生成相关报告。

基础环境：Linux 7.9+EMCC 13.5
卸载步骤：

一、拷贝脚本到执行目录
[oracle@oem install]$ cp EMDeinstall.pl /home/oracle/em

二、卸载OMS
OMS_HOME=/u01/app/oracle/oms

Refer to /home/oracle/em/deinstall_2024-02-12_11-24-24.log for deinstall log
Substring valuye is /u01/app/oracle/gc_inst
This is a First OMS install. So, this deinstalls the OMS , Repository and Agent. Confirm (y/n)y
