使用RMAN简单迁移表空间
确认环境: 源库: 系统:RedHat企业版5.4 数据库版本:Oracle 10.2.0.1.0 IP:10.37.100.100 目标库: 系统:RedHat企业版5.4
确认环境:
源库:
系统:RedHat企业版5.4
数据库版本:Oracle 10.2.0.1.0
IP:10.37.100.100
目标库:
系统:RedHat企业版5.4
数据库版本:ORACLE 10.2.0.3.0
IP:10.37.100.101
需要传输的表空间:TTS_TEST
检查一下环境:
源库上查看版本支持情况:
SQL> select db.name,db.platform_name,tp.endian_format
2 from v$transportable_platform tp,v$database db
3 where tp.platform_name=db.platform_name
4 /
NAME PLATFORM_NAME ENDIAN_FORMAT
--------- -------------------- --------------
ORCL Linux IA (32-bit) Little
查看数据库版本:
SQL> select version from v$instance;
VERSION
-----------------
10.2.0.1.0
备库上查看版本情况:
SQL> select db.name,db.platform_name,tp.endian_format
2 from v$transportable_platform tp,v$database db
3 where tp.platform_name=db.platform_name
4 /
NAME PLATFORM_NAME ENDIAN_FORMAT
--------- -------------------- --------------
ORCL Linux IA (32-bit) Little
源库上需要有整库和所有归档日志的备份
RMAN> backup database plus archivelog format '/u01/rman_backup/all_database_bak_%T_%t.bak';
RMAN> transport tablespace tts_test
2> tablespace destination '/u01/tts_dir/td'
3> auxiliary destination '/u01/tts_dir/ad';
此时传输表空间所需的数据文件,日志文件,,传输集及导入脚本均已生成在tablepsace desnation目录下,而auxilibary desnation路径下的临时文件已经被删除
[oracle@localhost td]$ cd /u01/tts_dir/td/
[oracle@localhost td]$ ls
dmpfile.dmp explog.log impscrpt.sql tts01.dbf tts02.dbf
[oracle@localhost td]$ cd /u01/tts_dir/ad/
[oracle@localhost ad]$ ls
TSPITR_ORCL_MWWE
[oracle@localhost ad]$ cd TSPITR_ORCL_MWWE/
[oracle@localhost TSPITR_ORCL_MWWE]$ ls
datafile onlinelog
[oracle@localhost TSPITR_ORCL_MWWE]$ cd datafile/
[oracle@localhost datafile]$ ls
[oracle@localhost datafile]$ cd ../onlinelog/
[oracle@localhost onlinelog]$ ls
将tablepsace desnation路径下生成的所有文件copy到目标库:
[oracle@localhost ~]$ scp 10.37.100.100:/u01/tts_dir/td/* /u01/tts_dir/
oracle@10.37.100.100's password:
dmpfile.dmp 100% 76KB 76.0KB/s 00:00
explog.log 100% 1226 1.2KB/s 00:00
impscrpt.sql 100% 2175 2.1KB/s 00:00
tts01.dbf 100% 20MB 20.0MB/s 00:01
tts02.dbf 100% 20MB 20.0MB/s 00:01
SQL> @/u01/tts_dir/impscrpt.sql

报错的原因是目标库的传输集路径跟源库的不一样,可以将传输集复制到相同的路径下,或者去修改一下impscrpt.sql中的路径:
[oracle@localhost tts_dir]$ vi impscrpt.sql
将一下两个路径修改成目标库下的传输集路径即可:
CREATE DIRECTORY STREAMS$DIROBJ$1 AS '/u01/tts_dir/';
CREATE DIRECTORY STREAMS$DIROBJ$DPDIR AS '/u01/tts_dir/';
再次执行脚本导入:
SQL> @/u01/tts_dir/impscrpt.sql
Directory created.
Directory created.
PL/SQL procedure successfully completed.

也可以直接使用inpdp命令导入(这种导入可以使用remap_schma参数来修改表空间的所属主)
[oracle@localhost tts_dir]$ impdp system/oracle dumpfile=dmpfile.dmp directory=tts_dir nologf
ile=y transport_datafiles=/u01/tts_dir/tts01.dbf,/u01/tts_dir/tts02.dbf remap_schema=tts:xtt;
