Oracle 11g r2 DataGuard安装配置
安装环境
1. ORACLE服务器硬件配置
硬盘 146*4
内存 16G
IP地址&机器名:
XXX. XXX. XXX. XXX platformdb01 #primary
XXX. XXX. XXX. XXX platformdb02 #standby
2. Oracle服务器分区
-------------------
分区 SIZE
/boot 100M #主分区
/u01 100G #主分区
/u02 150G #主分区
/ 60G #扩展分区
swap 16G #扩展分区
/rman 剩下的所有空间 #扩展分区 #250G
-------------------
3. RPM安装包选择

4. 配置图形界面环境（Xmanager）
a. 启动本地X服务器
安装Xmanager以后, 开始菜单 -> 程序 -> Xmanager3 -> Xmanager – Passive
b. 服务器端配置: /etc/ssh/sshd_config
确保有这行: X11Forwarding yes
c. root执行 #export DISPLAY=192.168.186.1:0.0 #本地客户端的IP地址
d. root执行 #xhost +
e. root执行 #xclock #本地应该有图形界面的钟出现
5. rlwrap安装（可选）
安装前准备
