Oracle 11gR2 RAC 删除节点

1. 概述

1.1 目标

生产数据库删除节点。

2. 删除前准备

2.1 DBCA删除数据库实例

在节点1以oracle用户运行dbca

2.2 RAC层面删除节点

node1 操作停止listener

[grid@node1-11gr2 ~]$ srvctl disable listener -l LISTENER -n node2-11gr2

[grid@node1-11gr2 ~]$

[grid@node1-11gr2 ~]$ srvctl stop listener -l LISTENER -n node2-11gr2

在node1更新inventory
