RMAN使用备份按时间点传输表空间
作者：互联网
使用until time或者SCN来执行transport tablespace
如果在执行传输表空间操作时，对transport tablespace命令指定了目标时间，那么RMAN将在辅助实例中使用备份将表空间还原到目标时间之前并执行按时间点恢复将辅助数据库恢复到指定的目标时间点。（对于按时间点恢复所需要的备份和重做日志必须可以使用）
恢复的目标时间可以使用SCN（包括当前incarnation或ancestors incarnation)，日志序列号，还原点或时间表达式。
使用SCN来执行transport tablespace
1.确认源数据库与目标数据库所在平台是不是传输表空间所支持的操作系统平台。确认源数据库操作系统平台:
SQL> select d.platform_name,endian_format from v$transportable_platform tp,v$database d 2 where tp.platform_name=d.platform_name ; PLATFORM_NAME ENDIAN_FORMAT ----------------------------------------------------------------------------------------------------- -------------- Linux IA (32-bit) Little
确认目数据库操作系统平台:
SQL> select d.platform_name,endian_format from v$transportable_platform tp,v$database d 2 where tp.platform_name=d.platform_name ; PLATFORM_NAME ENDIAN_FORMAT ----------------------------------------------------------------------------------------------------- -------------- Linux IA (32-bit) Little
这里操作系统平台都是Linux
2.确认要被传输的表空间是否是自包含表空间(TSPITR,TEST):
SQL> exec sys.dbms_tts.transport_set_check('TSPITR',true);
PL/SQL procedure successfully completed.
SQL> exec sys.dbms_tts.transport_set_check('TEST',true);
PL/SQL procedure successfully completed.
SQL> select * from sys.transport_set_violations;
no rows selected
如果没有行选择，表示该表空间只包含表数据，可以传输。
修改表tspitr与test中的记录,在修改之前记录当前的SCN，在执行传输表空间时指定这个SCN
SQL> conn tspitr/tspitr Connected. SQL> select current_scn from v$database; CURRENT_SCN ----------- 1167731 SQL> select to_char(scn_to_timestamp(1167731),'yyyy-mm-dd hh24:mi:ss') from dual; TO_CHAR(SCN_TO_TIME ------------------- 2015-03-27 16:48:29 SQL> insert into tspitr select * from tspitr; 50641 rows created. SQL> commit; Commit complete. SQL> select count(*) from tspitr COUNT(*) ---------- 101282 SQL> conn test/test Connected. SQL> select count(*) from test; COUNT(*) ---------- 50680 SQL> delete from test; 50680 rows deleted. SQL> commit; Commit complete. SQL> select count(*) from test; COUNT(*) ---------- 0
在SCN=1167731之后，表tspitr中的记录数为101282，表test的记录数为0,SCN=1167731之前，表tspitr中的记录数为50641，表test的记录数为50680
3.对源数据库执行备份，在执行备份时一定要加上include current controlfile否则执行transport tablespace命令时会出现以下错误信息：

4.在这里指定了auxiliary destination子句让RMAN使用缺省值来管理辅助实例。只指定必须的选项。Oracle建议transport tablespace命令使用辅助目录秋简化辅助实例文件的管理。下面来执transport tablespace命令来传输tspitr,test两个表空间:
[oracle@oracle11g ~]$ export NLS_DATE_FORMATE='yyyy-mm-dd hh24:mi:ss';
[oracle@oracle11g ~]$ rman target sys/zzh_2046@test catalog rman/rman@jy

5.将步骤4生成的传输表空间的数据文件tspitr01.dbf,test01.dbf和Data Pump导出文件dmpfile拷贝到目标主机上的/u02目录中
[oracle@jingyong1 u02]$ scp -r oracle@192.168.56.2:/u02/transport/tspitr01.dbf /u02 oracle@192.168.56.2's password: tspitr01.dbf 100% 100MB 7.1MB/s 00:14 [oracle@jingyong1 u02]$ scp -r oracle@192.168.56.2:/u02/transport/test01.dbf /u02 oracle@192.168.56.2's password: test01.dbf 100% 10MB 10.0MB/s 00:00 [oracle@jingyong1 u02]$ scp -r oracle@192.168.56.2:/u02/transport/dmpfile.dmp /u02 oracle@192.168.56.2's password: dmpfile.dmp 100% 96KB 96.0KB/s 00:00 [oracle@jingyong1 u02]$ ls -lrt total 112876 -rw-r----- 1 oracle oinstall 104865792 Mar 27 17:54 tspitr01.dbf -rw-r----- 1 oracle oinstall 10493952 Mar 27 18:22 test01.dbf -rw-r----- 1 oracle oinstall 98304 Mar 27 18:22 dmpfile.dmp
6.在目录主机上创建相关用户及Data Pump目录并将表空间附加到目标数据库中
SQL> create user tspitr identified by "tspitr"; User created. SQL> grant dba,connect,resource to tspitr; Grant succeeded. SQL> create user test identified by "test"; User created. SQL> grant dba,connect,resource to test; Grant succeeded. SQL> create directory mytest as '/u02'; Directory created. SQL> grant read,write on directory mytest to public; Grant succeeded.
最后就可以执行导入过程了
[oracle@jingyong1 ~]$ export ORACLE_SID=jy [oracle@jingyong1 ~]$ export NLS_DATE_FORMATE='yyyy-mm-dd hh24:mi:ss' [oracle@jingyong1 ~]$ impdp test/test directory=mytest dumpfile=dmpfile.dmp logfile=testtransport.log transport_datafiles= /u02/tspitr01.dbf, /u02/test01.dbf Import: Release 10.2.0.5.0 - Production on Friday, 27 March, 2015 18:25:25 Copyright (c) 2003, 2007, Oracle. All rights reserved. Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - Production With the Partitioning, OLAP, Data Mining and Real Application Testing options Master table "TEST"."SYS_IMPORT_TRANSPORTABLE_01" successfully loaded/unloaded Starting "TEST"."SYS_IMPORT_TRANSPORTABLE_01": test/******** directory=mytest dumpfile=dmpfile.dmp logfile=testtransport.log transport_datafiles= /u02/tspitr01.dbf, /u02/test01.dbf Processing object type TRANSPORTABLE_EXPORT/PLUGTS_BLK Processing object type TRANSPORTABLE_EXPORT/TABLE Processing object type TRANSPORTABLE_EXPORT/TABLE_STATISTICS Processing object type TRANSPORTABLE_EXPORT/POST_INSTANCE/PLUGTS_BLK Job "TEST"."SYS_IMPORT_TRANSPORTABLE_01" successfully completed at 18:25:49
进入数据库中检查一下
SQL> select count(*) from tspitr.tspitr; COUNT(*) ---------- 50641 SQL> select count(*) from test.test; COUNT(*) ---------- 50680
与SCN=1167731之前的状态一致。
下面来演示使用until time执行传输表空间
1.确认源数据库与目标数据库所在平台是不是传输表空间所支持的操作系统平台。
确认源数据库操作系统平台:
SQL> select d.platform_name,endian_format from v$transportable_platform tp,v$database d 2 where tp.platform_name=d.platform_name ; PLATFORM_NAME ENDIAN_FORMAT ----------------------------------------------------------------------------------------------------- -------------- Linux IA (32-bit) Little
确认目数据库操作系统平台:
SQL> select d.platform_name,endian_format from v$transportable_platform tp,v$database d 2 where tp.platform_name=d.platform_name ; PLATFORM_NAME ENDIAN_FORMAT ----------------------------------------------------------------------------------------------------- -------------- Linux IA (32-bit) Little
这里操作系统平台都是Linux
2.确认要被传输的表空间是否是自包含表空间(TSPITR,TEST):
SQL> exec sys.dbms_tts.transport_set_check('TSPITR',true);
PL/SQL procedure successfully completed.
SQL> exec sys.dbms_tts.transport_set_check('TEST',true);
PL/SQL procedure successfully completed.
SQL> select * from sys.transport_set_violations;
no rows selected
如果没有行选择，表示该表空间只包含表数据，可以传输。
修改表tspitr与test中的记录
在修改之前记录当前的系统时间，在执行传输表空间时指定这个系统时间。
SQL> conn tspitr/tspitr Connected. SQL> select to_char(sysdate,'yyyy-mm-dd hh24:mi:ss') from dual; TO_CHAR(SCN_TO_TIME ------------------- 2015-03-27 16:48:29 SQL> insert into tspitr select * from tspitr; 50641 rows created. SQL> commit; Commit complete. SQL> select count(*) from tspitr COUNT(*) ---------- 101282 SQL> conn test/test Connected. SQL> select count(*) from test; COUNT(*) ---------- 50680 SQL> delete from test; 50680 rows deleted. SQL> commit; Commit complete. SQL> select count(*) from test; COUNT(*) ---------- 0
在2015-03-27 16:48:29之后，表tspitr中的记录数为101282，表test的记录数为0,2015-03-27 16:48:29之前，表tspitr中的记录数为50641，表test的记录数为50680
3.对源数据库执行备份，在执行备份时一定要加上include current controlfile否则执行transport tablespace命令时会出现以下错误信息：

4.在这里指定了auxiliary destination子句让RMAN使用缺省值来管理辅助实例。只指定必须的选项。Oracle建议transport tablespace命令使用辅助目录秋简化辅助实例文件的管理。下面来执transport tablespace命令来传输tspitr,test两个表空间:
RMAN> transport tablespace "TSPITR","TEST" tablespace destination '/u02/transport' auxiliary destination '/u02/transport' until time "to_date('2015-03-27 16:48:29','yyyy-mm-dd hh24:mi:ss')";

5.将步骤4生成的传输表空间的数据文件tspitr01.dbf,test01.dbf和Data Pump导出文件dmpfile拷贝到目标主机上的/u02目录中
[oracle@jingyong1 u02]$ scp -r oracle@192.168.56.2:/u02/transport/tspitr01.dbf /u02 oracle@192.168.56.2's password: tspitr01.dbf 100% 100MB 7.1MB/s 00:14 [oracle@jingyong1 u02]$ scp -r oracle@192.168.56.2:/u02/transport/test01.dbf /u02 oracle@192.168.56.2's password: test01.dbf 100% 10MB 10.0MB/s 00:00 [oracle@jingyong1 u02]$ scp -r oracle@192.168.56.2:/u02/transport/dmpfile.dmp /u02 oracle@192.168.56.2's password: dmpfile.dmp 100% 96KB 96.0KB/s 00:00 [oracle@jingyong1 u02]$ ls -lrt total 112876 -rw-r----- 1 oracle oinstall 104865792 Mar 27 17:54 tspitr01.dbf -rw-r----- 1 oracle oinstall 10493952 Mar 27 18:22 test01.dbf -rw-r----- 1 oracle oinstall 98304 Mar 27 18:22 dmpfile.dmp
6.在目录主机上创建相关用户及Data Pump目录并将表空间附加到目标数据库中
SQL> create user tspitr identified by "tspitr"; User created. SQL> grant dba,connect,resource to tspitr; Grant succeeded. SQL> create user test identified by "test"; User created. SQL> grant dba,connect,resource to test; Grant succeeded. SQL> create directory mytest as '/u02'; Directory created. SQL> grant read,write on directory mytest to public; Grant succeeded.
最后就可以执行导入过程了
[oracle@jingyong1 ~]$ export ORACLE_SID=jy [oracle@jingyong1 ~]$ export NLS_DATE_FORMATE='yyyy-mm-dd hh24:mi:ss' [oracle@jingyong1 ~]$ impdp test/test directory=mytest dumpfile=dmpfile.dmp logfile=testtransport.log transport_datafiles= /u02/tspitr01.dbf, /u02/test01.dbf Import: Release 10.2.0.5.0 - Production on Friday, 27 March, 2015 20:28:39 Copyright (c) 2003, 2007, Oracle. All rights reserved. Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - Production With the Partitioning, OLAP, Data Mining and Real Application Testing options Master table "TEST"."SYS_IMPORT_TRANSPORTABLE_01" successfully loaded/unloaded Starting "TEST"."SYS_IMPORT_TRANSPORTABLE_01": test/******** directory=mytest dumpfile=dmpfile.dmp logfile=testtransport.log transport_datafiles= /u02/tspitr01.dbf, /u02/test01.dbf Processing object type TRANSPORTABLE_EXPORT/PLUGTS_BLK Processing object type TRANSPORTABLE_EXPORT/TABLE Processing object type TRANSPORTABLE_EXPORT/TABLE_STATISTICS Processing object type TRANSPORTABLE_EXPORT/POST_INSTANCE/PLUGTS_BLK Job "TEST"."SYS_IMPORT_TRANSPORTABLE_01" successfully completed at 20:28:55 进入数据库中检查一下 SQL> select count(*) from tspitr.tspitr; COUNT(*) ---------- 50641 SQL> select count(*) from test.test; COUNT(*) ---------- 50680
与2015-03-27 16:48:29之前的状态一致。 下面演示使用还原点来执行传输表空间 1.确认源数据库与目标数据库所在平台是不是传输表空间所支持的操作系统平台。 确认源数据库操作系统平台:
SQL> select d.platform_name,endian_format from v$transportable_platform tp,v$database d 2 where tp.platform_name=d.platform_name ; PLATFORM_NAME ENDIAN_FORMAT ----------------------------------------------------------------------------------------------------- -------------- Linux IA (32-bit) Little
确认目数据库操作系统平台:
SQL> select d.platform_name,endian_format from v$transportable_platform tp,v$database d 2 where tp.platform_name=d.platform_name ; PLATFORM_NAME ENDIAN_FORMAT ----------------------------------------------------------------------------------------------------- -------------- Linux IA (32-bit) Little
这里操作系统平台都是Linux
2.确认要被传输的表空间是否是自包含表空间(TSPITR,TEST):
SQL> exec sys.dbms_tts.transport_set_check('TSPITR',true);
PL/SQL procedure successfully completed.
SQL> exec sys.dbms_tts.transport_set_check('TEST',true);
PL/SQL procedure successfully completed.
SQL> select * from sys.transport_set_violations;
no rows selected
如果没有行选择，表示该表空间只包含表数据，可以传输。
修改表tspitr与test中的记录,在修改之前创建一个还原点，在执行传输表空间时指定这个还原点
SQL> select count(*) from test; COUNT(*) ---------- 0 SQL> select count(*) from tspitr.tspitr; COUNT(*) ---------- 101282 SQL> create restore point before_update; Restore point created. SQL> insert into test select * from dba_objects; 50683 rows created. SQL> commit; Commit complete. SQL> delete from tspitr.tspitr; 101282 rows deleted. SQL> commit; Commit complete. SQL> select count(*) from test; COUNT(*) ---------- 50683 SQL> select count(*) from tspitr.tspitr; COUNT(*) ---------- 0
在创建还原点before_update之后，表tspitr中的记录数为0，表test的记录数为50683,before_update之前，表tspitr中的记录数为101282，表test的记录数为0。
3.对源数据库执行备份，在执行备份时一定要加上include current controlfile否则执行transport tablespace命令时会出现以下错误信息：

4.在这里指定了auxiliary destination子句让RMAN使用缺省值来管理辅助实例。只指定必须的选项。Oracle建议transport tablespace命令使用辅助目录秋简化辅助实例文件的管理。下面来执transport tablespace命令来传输tspitr,test两个表空间:
RMAN> transport tablespace "TSPITR","TEST" tablespace destination '/u02/transport' auxiliary destination '/u02/transport' UNTIL RESTORE POINT 'before_update'; RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03002: failure of tranport tablespace command at 03/27/2015 20:42:53 RMAN-00600: internal error, arguments [5085] [point] [] [] []
出现RMAN-00600 internal error, arguments [5085] [point]，在MOS上有一篇关于这个错误的文章，是ORACLE的bug,请参考Bug 8571266 - RMAN TSPITR to restore point fails with RMAN-600 [5085] (Doc ID 8571266.8),说这个Bug在11.2.0.2中已经修复了。
