背景

環境：

oracle為11.2版本 Linux-Centos6.5操作系統。

現狀：

兩臺主機198，197 ，均已安裝了oracle服務端。

其中198上已經創建了兩個實例，197上只有orcl實例。

需要在197上搭建一套環境，數據保持和198一致。

步驟概述

停198數據庫

將/oracle/product/112/dbs目錄下的全部文件copy到197對應目錄

/oracle/admin目錄以及子目錄遷到197對應目錄 ，文件可以不遷。

/oradata/instance1 /oradata/instance2 全部文件數據遷到197對目錄

數據庫監聽同步修改

操作步驟

停止198庫

使用 oracle用戶操作 su - oracle

copy數據到197對應目錄

scp -r /oracle/product/112/dbs oracle@10.45.7.197:/oracle/product/112/scp -r /oradata/instance1/ oracle@10.45.7.197:/oradata/scp -r /oradata/instance2/ oracle@10.45.7.197:/oradata/

操作之前請先確保197主機對應目錄存在，確保存儲空間足夠.

啟動197主機上的實例

自此OK,數據庫可以正常訪問了.
