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)
