Oracle 10g DG 数据文件迁移的实现(2/4)

3.1 确认需要迁移的数据文件

查看当前的数据文件，确认将9,10,11三个文件迁移回原来的目录：

 SQL> select file#, name from v$datafile;

   FILE# NAME
---------- -------------------------------------------------------
     1 /oradata/jy/datafile/system.256.839673875
     2 /oradata/jy/datafile/undotbs1.258.839673877
     3 /oradata/jy/datafile/sysaux.257.839673877
     4 /oradata/jy/datafile/users.259.839673877
     5 /oradata/jy/datafile/example.267.839673961
     6 /oradata/jy/datafile/undotbs2.268.839674103
     7 /oradata/jy/datafile/dbs_d_school.276.840618437
     8 /oradata/jy/datafile/dbs_cssf_gt.289.848228741
     9 /datafile/dbs_data9.dbf
    10 /datafile/dbs_data10.dbf
    11 /datafile/dbs_data11.dbf

11 rows selected. 

3.2 备份相关数据文件副本：

编写脚本：

 vi copy_datafile.sh
 echo "=======Begin at : `date`=======" >>/tmp/copy_datafile_`date +%Y%m%d`.log
rman target / <>/tmp/copy_datafile_`date +%Y%m%d`.log
run {
allocate channel c1 device type disk;
allocate channel c2 device type disk;
allocate channel c3 device type disk;

backup as copy datafile 9 format '/oradata/jy/datafile/dbs_data9.dbf';
backup as copy datafile 10 format '/oradata/jy/datafile/dbs_data10.dbf';
backup as copy datafile 11 format '/oradata/jy/datafile/dbs_data11.dbf';

release channel c1;
release channel c2;
release channel c3;
}
EOF
echo "=======End at : `date`=======" >>/tmp/copy_datafile_`date +%Y%m%d`.log 

后台执行脚本：nohup sh copy_datafile.sh &
