使用rman from service 搭建dataguard

从oracle 12c开始提供了rman通过from service方式搭建dg,使用12c长期支持版19c(并打上最新的patch)
配置dataguard相关参数(主备库有稍微不同)

alter system set db_unique_name='XIFENFEI' scope=spfile;
alter system set service_names='XIFENFEI';
alter system set log_archive_config='dg_config=(XIFENFEI,XIFENFEIDG)';
alter system set log_archive_dest_1='LOCATION=USE_DB_RECOVERY_FILE_DEST 
  valid_for=(all_logfiles,all_roles) db_unique_name=XIFENFEI';
alter system set log_archive_dest_2='service=XIFENFEIDG lgwr async 
 valid_for=(online_logfiles,primary_role) db_unique_name=XIFENFEIDG';
alter system set standby_file_management=auto;
alter system set db_file_name_convert='/u01/app/oracle/oradata/XIFENFEI/',
 '/u01/app/oracle/oradata/XIFENFEI/' scope=spfile;
alter system set log_file_name_convert='/u01/app/oracle/oradata/XIFENFEI/',
 '/u01/app/oracle/oradata/XIFENFEI/' scope=spfile;
alter system set fal_server=XIFENFEIDG;

配置tnsnames.ora

XIFENFEI =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.238)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = XIFENFEI)
    )
  )

XIFENFEIDG =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.124)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = XIFENFEI)
    )
  )

拷贝主库密码文件到备库

rman备份到win共享目录

在win环境中数据库备份到异地,相对来说没有linux的nfs方便(可能nfs使用多了比较熟悉),以前写过一篇文章(windows rman自动备份并传输到远程服务器处理方法),通过本地备份,然后拷贝到远程共享目录实现,相对来说该方案比较繁琐,这次尝试直接备份到共享目录
1. 服务配置
20190926221926


oracle数据库服务和监听服务配置使用此账户的方式登录(而不是默认的本地系统账号)

2.在目标服务器中配置共享
20190926222029

主要两台win服务器登录用户名和密码需要一致,最好也是数据库安装用户

3.数据库备份脚本
20190926222130

备份脚本路径使用\\方式而不能使用别名盘符

4.数据库备份计划任务
20190926222951

运行任务时请使用下列用户选择ORA_DBA

这里本质就是通过oracle内部包,直接还原数据文件,这个模拟的是基础的情况,在实际的恢复中,由于只有数据文件的备份,可能文件不一致,还需要通过一些非常规方法对数据库进行强制打开
