自动处理 database server->customize
Now->databases不安装
MysqL.postgre
sql数据库->Desktops->Desktop.xwindowssy
stem->Development除eclipse，其他全安装。 vi /etc/hosts 192.168.122.4 dg1 192.168.122.5 dg2 1.规划 主库(192.168.122.4)dg1： db_name dg1 db_unique_name dg1 service_name dg1 instance_name dg1 本地归档路径 /u01/app/oracle/oradata/dg1/archivelog tnsnames dg2 --配置去备库的tns 备库(192.168.122.5)dg2： db_name dg1
数据库名要一样 db_unique_name dg2 在
一个dg环境里面，每
一个成员的名字。 servicer_name dg2 instance_name dg2 实例名可以不一样 本地归档路径 /u01/app/oracle/oradata/dg1/archivelog tnsnames dg1 --配置去主库的tns 2.安装ORACLE 在VNC下使用Oracle
用户安装软件，，无法正常
显示图形界面
解决办法:root
