當oracle在非歸檔情況執行時，又需要備份資料庫，那麼exp/expdp作為匯出，imp/impdp作為匯入時不錯的選擇。
下面是一個簡單的全庫匯出的指令碼
[oracle@BIDB scripts]$ cat full_bak.sh 
#!/bin/bash
. /home/oracle/.bash_profile
cd /orabak/dbbak

echo "#######################################################" >> /orabak/log/full.txt
echo "starting delete logfile at `date`" >> /orabak/log/full.txt
find /orabak/dbbak -mtime +7 -name "*.log" -exec rm -rf {} \;
echo "complete delete logfile at `date`" >> /orabak/log/full.txt

echo "#######################################################" >> /orabak/log/full.txt
echo "starting delete dumpfile at `date`" >> /orabak/log/full.txt
find /orabak/full -mtime +7 -name "*.dmp" -exec rm -rf {} \;
echo "complete delete dumpfile at `date`" >> /orabak/log/full.txt

echo "#######################################################" >> /orabak/log/full.txt
echo "starting backup of database at `date`" >> /orabak/log/full.txt
expdp "'/ as sysdba'" directory=full_expdp dumpfile=full_%U.dmp full=y parallel=16 compression=ALL filesize=10G logfile=full_expdp.log job_name=expdp_job1;
echo "complete backup of database at `date`" >> /orabak/log/full.txt

mkdir -p /orabak/full/`date +%Y%m%d` && cd /orabak/full/`date +%Y%m%d`
echo "#############################################################" >> /orabak/log/cp.txt
echo "starting copy dumpfile to target file       at `date`" >> /orabak/log/full.txt
cp /orabak/full/*.dmp /orabak/full/`date +%Y%m%d`
cp /orabak/full/*.log /orabak/full/`date +%Y%m%d`
echo "complete copy dumfile `date`" >> /orabak/log/full.txt

如果需要做匯入：
impdp \'/ as sysdba\' directory=imp27 full=y dumpfile=full_%U.dmp logfile=fullimp.log parallel=10 
相關的引數，根據機器的配置來選擇。
