本篇內容主要講解“Oracle RAC+DG環境搭建的方法是什么”，感興趣的朋友不妨來看看。本文介紹的方法操作簡單快捷，實用性強。下面就讓小編來帶大家學習“Oracle RAC+DG環境搭建的方法是什么”吧!
分兩個腳本 env.sh 和rpm.sh
env.sh 整體腳本如下，修改相關數據庫實例名后，在四臺主機上直接執行：
#!/bin/bash
#
#Purpose: 1. set the Environment and OS parameter
# 2. create 6 groups (oinstall,dba,oper,asmadmin,asmdba,asmoper) and 2 user(oracle,grid)
# 3. create the necessary directory
#
#Usage: It would be called by main.sh or you can execute it alonely and Separately in two nodes.
# Log on as the superuser('root'),and then execute this script
#
#Notice:
# 2. you can edit the config firtly. It will be run in two nodes, so you must modify
# ORACLE_SID and ORACLE_SID_GRID
