Oracle 10g DG 数据文件迁移
背景：某客户Oracle 10g 的DG由于空间不足，之前将部分数据文件迁移到其他目录，如今原目录扩容成功，要将之前迁移的数据文件再次迁移回来。
环境：Oracle 10.2.0.5 DG 单机
首先想到的是10gDG是在mount模式下应用的，在测试环境可以很容易的模拟下这个需求实现的过程：
1.查询当前DG的状态
**查询当前DG的状态:**
Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
SQL> select name, database_role, open_mode from gv$database;
NAME DATABASE_ROLE OPEN_MODE
--------- ---------------- ----------
JY PHYSICAL STANDBY MOUNTED
SQL> select recovery_mode from v$archive_dest_status;

---------------------------------- ---------------------------------------------------------------- ------------------------------ ------------------------------
apply finish time +00 00:00:00.0 day(2) to second(1) interval 05-MAY-2018 10:04:20
apply lag +00 00:00:12 day(2) to second(0) interval 05-MAY-2018 10:04:20
estimated startup time 41 second 05-MAY-2018 10:04:20
standby has been open N 05-MAY-2018 10:04:20
transport lag +00 00:00:00 day(2) to second(0) interval 05-MAY-2018 10:04:20
可以看到DG处于正常应用状态。
2.停止DG应用
**停止DG应用：**
SQL> alter database recover managed standby database cancel;
Database altered.
3.备份copy副本到新目录并切换
**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 / <<EOF >>/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 &
记录的日志如下：

3.3 切换数据文件到copy副本：

datafile 10 switched to datafile copy "/oradata/jy/datafile/dbs_data10.dbf"
datafile 11 switched to datafile copy "/oradata/jy/datafile/dbs_data11.dbf"
4.删除之前的目录并开启应用

至此，就完成了客户的需求，我们可以多思考一下，如果客户环境是11g的ADG环境呢？会有哪些不同呢？
