1、打开最小附加日志

alter database add supplemental log data;

2、打开归档

STARTUP MOUNT

ALTER DATABASE ARCHIVELOG;

ALTER DATABASE OPEN;

archive log list

Database log mode Archive Mode

3、打开强制归档

alter database force logging;

select force_logging, supplemental_log_data_min from v$database;

FORCE_LOGGING SUPPLEME

--------------------------------------- --------

YES YES

4、设置归档路径

ASM

alter system set log_archive_dest_1= 'location=+datadg' scope=both sid='*';

文件系统

alter system set log_archive_dest_1='location=/arch' scope=both sid='*

show parameter log_archive_dest_1

NAME TYPE VALUE

------------------------------------ -----------

------------------------------

log_archive_dest_1 string location=+datadg

log_archive_dest_10 string

log_archive_dest_11 string

log_archive_dest_12 string

log_archive_dest_13 string

log_archive_dest_14 string

log_archive_dest_15 string

log_archive_dest_16 string

log_archive_dest_17 string

log_archive_dest_18 string

log_archive_dest_19 string

5、rman 备份

run{

allocate channel c1 device type disk;

allocate channel c2 device type disk;

allocate channel c3 device type disk;

backup as backupset filesperset 2 database format '/orabak/rman/database_%T_%s_

%d_%p'

skip inaccessible;

sql 'alter system archive log current';

backup archivelog all format '/orabak/rman/arch_%d_%T_%s_%p' delete all input;

backup spfile format '/orabak/rman/spfile_%d_%T_%s_%p';

backup current controlfile format '/orabak/rman/contl_%d_%T_%s_%p';

}

6、scp 传输给 19C 服务器

scp 18Cbak.tar.gz oracle@192.168.100.98:/orabak/rman
