备份脚本：

source ~/.bash_profile

export BACK_DATE=`date +%Y%m%d`

export BACKUP_PATH=/data/spi_bak/script/rman

echo `mkdir -p ${BACKUP_PATH}/${BACK_DATE}`

rman target /  msglog=${BACKUP_PATH}/${BACK_DATE}/bak_0_$BACK_DATE.log << EOF

数据文件损坏：

1、offline数据文件
SQL>alter database datafile ‘/u01/data/orcl/block_ts01.dbf’ offline;

2、copy数据文件到响应的位置(RMAN)
rman>run {
recover copy of database with tag ‘incr_datafile8’;
backup incremental level 1 for recover of copy with tag ‘incr_datafile8’ datafile 8 format=‘/backup/datacopy/level1_%d_%T_%s.dbf’;
}

3、对数据文件rename
SQL>alter database rename file ‘/u01/data/orcl/tbs10.dbf’
to ‘/flashback/ORCL/datafile/o1_mf_tbs10_dn9plmd8_.dbf’;

4、recover数据文件
SQL>recover datafile ‘+DATADG/ywkdb/datafile/TS_XG_D.dbf’;

5、对数据文件online
SQL>alter database datafile ‘+DATADG/ywkdb/datafile/TS_XG_D.dbf’ online;
