expdp到ASM 文件系统并拷贝

1.创建asm导出数据目录

sql>select name,total_mb,free_mb from v$asm_diskgroup;

确认集群asm磁盘组环境

asmcmd>cd +DGDSDB

asmcmd>mkdir dpbak

asmcmd>ls -l

sql>conn / as sysdba

create directory expdp_asm_dir as '+DGDSDB/dpbak';

create directory expdp_log_dir as '/home/oracle';

2.导出数据

cd /home/oracle

expdp \'/ as sysdba\' directory=expdp_asm_dir dumpfile=用户_%U.dmp parallel=8 logfile=expdp_log_dir:用户.log schemas=用户 compression=all cluster=n

nohup ./expdp.sh &>/dev/null &

tail -f 用户.log

ps -ef|grep expdp.sh

取消导出

select job_name,state from dba_datapump_jobs;

expdp \'/ as sysdba\' attach=SYS_EXPORT_SCHENA_02

stop_job

kill_job

3.asm到asm

asmcmd>cd +data/orcl/dpbak

asmcmd>ls -l

分别在源端与目标端授予sys用户sysasm权限

sql>grant sysasm to sys;

拷贝前检查目标端监听，是否监听了ASM实例

检查目标端磁盘组空间

sql>select name,total_mb,free_mb from v$asm_diskgroup;

asmcmd>cp +data/oracl/dpbak/dmpfile sys@目标端ip.+ASM:+data/orcl/dpbak/dmpfile
