一、主库全备份

rman target /

run {

backup as compressed backupset filesperset 1 format ‘/home/oracle/dg/full_db_%d_%s_%t’ database ;

}

二、备份控制文件

sql>alter database create standby controlfile as ‘/home/oracle/dg/control01.ctl’;

三、备份参数文件

sql>create pfile=’/home/oracle/dg/initorcl.ora’ from spfile;

四、启动force_logging

sql>alter database force logging;

sql>select FORCE_LOGGING from v$database;

密码 居然在asm里边 好恶心

srvctl config database -d oriepay 查看密码在哪里啊 在哪里

主库

alter system set log_archive_dest_2=‘service=orcl_dg valid_for=(online_logfiles,primary_role) lgwr async NOAFFIRM db_unique_name=orcl_dg’ scope=both sid=’’;

alter system set log_archive_dest_state_2=enable scope=both sid=’’;

alter system set log_archive_config=‘dg_config=(orcl_rac,orcl_dg)’ scope=both sid=’*’;

配置tns 主库 到 备库 互通 ok

SELECT * FROM V$DATAGUARD_STATUS;

select process,status from v$managed_standby;

select process,status,client_process,thread#,sequence# from v$managed_standby;

6.1 如果启动归档应用

sql>alter database recover managed standby database disconnect from session;

6.2 如果启动实时应用

ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE disconnect from session;

7) 取消应用的命令如下：

ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;

alter database clear logfile group 31;

alter database clear logfile group 32;

alter database clear logfile group 33;

alter database clear logfile group 34;

alter database clear logfile group 24;

alter database clear logfile group 21;

alter database clear logfile group 22;

alter database clear logfile group 23;
