Oracle 12c DG配置（两节点）
一、系统版本
1.操作系统
[oracle@DB1 ~]$ cat /etc/redhat-release
CentOS Linux release 7.7.1908 (Core)
2.数据库
3.节点情况
DB1:
DB2:
| 序号 | 主库（10.1.1.100） | 备库（10.1.1.130） |
| 1 | sid：orcl | sid：orcl |
| 2 | db_unique_name='orcl_pd' | db_unique_name='orcl_st' |
注：12c的物理DG是基于cdb级别的；
二、安装数据库（安装主库软件和建库，备库只需安装数据库软件）
见安装数据库章节；（此处略）
三、配置主库
1.归档
关机 shutdown immediate;
启动数据库到mount状态 startup mount;
启动归档：alter database archivelog;
启动数据库：alter database open;
设置归档目录：
SQL>alter system set log_archive_dest_1='location=/archivelog1/' scope=spfile ;
SQL>alter system set log_archive_format='arch_%t_%s_%r.arc' scope=spfile;
2.强制日志
SQL> alter database force logging;
3.创建standby redo log日志组
SQL> alter database add standby logfile '/oradata/orcl/stdredo01.log' size 200M;
SQL> alter database add standby logfile '/oradata/orcl/stdredo01.log' size 200M;
SQL> alter database add standby logfile '/oradata/orcl/stdredo01.log' size 200M;
SQL> alter database add standby logfile '/oradata/orcl/stdredo01.log' size 200M;
4.修改参数文件
创建参数文件：create pfile='/home/oracle/pfile.ora' from spfile;
[oracle@DB1 ~]$ vi pfile.ora
[oracle@DB1 ~]$ cat pfile.ora

5.修改listener.ora和tnsname.ora文件并测试

4.启用备库到read only状态
五、测试
1.测试数据同步状态
查看主库状态：
