Oracle11g RMAN跨平台传输表空间

Linux操作系统 作者:jugjugjj 时间:2014-03-07 16:14:41 0 删除 编辑

利用imp/impdp传输表空间transport_tablespace满足以下条件
1.字符集相同
2.要导出的表空间必须是read only,而且是自包含的,就是说该表空间的对象不能依赖其他表空间。
3.先导出源数据,传输表空间的数据文件拷贝到另一个数据库相应目录下。
而RMAN不需要表空间READ ONLY,因为它是备份集进行传输,但是也需要字符集相同和自包含。
下面基于RMAN传输表空间的测试。
测试环境
源数据库:
OS=RHEL 6.4;
DB=ORACLE11GR2 ;
IP=192.168.1.171;
SID=hjj;
ASM存储。
目标数据库:
OS=WIN7 64BIT;
DB=ORACLE11GR2;
IP=192.168.1.1;
SID=orcl;
FS存储。
一、在源数据库端
1.创建测试表空间
SQL> create tablespace tt1 datafile '+DATA_DG/hjj/datafile/test01.dbf' size 100m;

Tablespace created.
2.创建用户并授权
SQL> create user tt1 identified by oracle default tablespace tt1;

User created.

SQL> grant connect,resource to tt1;

Grant succeeded.
3.创建测试表
SQL> create table tt1.t as select * from dba_objects;

Table created.
4.查看数据
SQL> conn tt1/oracle
Connected.
SQL> select count(*) from t;

  COUNT(*)
----------
     21293
4.确认传输表空间的平台是否兼容
在源数据库端:
SQL> select tp.* from v$transportable_platform tp,v$database d where tp.PLATFORM_NAME = d.PLATFORM_NAME;

PLATFORM_ID PLATFORM_NAME                                      ENDIAN_FORMAT
----------- -------------------------------------------------- --------------
         10 Linux IA (32-bit)                                  Little
在目标数据库端:
SQL> select tp.* from v$transportable_platform tp,v$database d where tp.PLATFORM_NAME = d.PLATFORM_NAME;

PLATFORM_ID PLATFORM_NAME                                      ENDIAN_FORMAT
----------- -------------------------------------------------- ----------------------------
         12 Microsoft Windows x86 64-bit                       Little
可以看到windows平台和linux都是Little,是兼容的。
5.确认源数据库的表空间是否自包含
SQL> exec dbms_tts.transport_set_check('tt1',true,true);

PL/SQL procedure successfully completed.

SQL> select * from transport_set_violations;

no rows selected
6.备份源数据库

说明:这里使用全库备份,因为除了目标表空间的备份以外,RMAN还需要SYSTEM、SYSAUX以及UNDO表空间的备份,如果任意一个表空间的备份不存在,则就会导致“RMAN-06019: 无法转换表空间名称"TTB1"”的错误。

impscrpt.sql --元数据信息,目标数据库必须存在相应的对象属主,数据文件路径不一致还要修改脚本。
dmpfile.dmp --也是元数据信息,如果使用dump文件导入元数据信息则就没有上面的限制了。
tt01.dbf --数据文件,可以发现生成的数据文件和原来的数据文件一模一样。
HJJ是/s01/dd下的一个临时目录。

8.目标数据库中导入元数据集
a.使用asm存储体系,使用dump导入
convert datafile '/opt/tts/td/tts.288.755520393' format '+datagroup';
如果是使用的asm则需要把os上面的文件放到asm里面,上面这条命令可以在os和asm之间转换数据文件。
impdp system/oracle@orcl directory=dp dumpfile=dmpfile.dmp nologfile=y transport_datafiles='+DATAGROUP/ORCL/DATAFILE/TTS.290.755528197';
b.使用文件系统,使用dump导入。
impdp system/oracle@orcl directory=dp dumpfile=dmpfile.dmp nologfile=y transport_datafiles='/opt/oradata/tts.288.755520393';
c.@/opt/tts/td/impsctpt.sql
9.复制源数据库/s01/dd目录和数据文件到目标数据库D:dd
D:dd>ls
dmpfile.alg   dmpfile.dmp   impscrpt.sql  tt01.dbf
10.检查源数据库和目标数据库的数据块大小是否一致
源数据库:
SQL> select block_size from dba_tablespaces where tablespace_name = 'TT1'; 

BLOCK_SIZE
----------
      8192
目标数据库:
SQL> show parameter db_block_size

NAME                                 TYPE                   VALUE
------------------------------------ ---------------------- ---------

再次使用impdp导入

impdp执行,你可以运行impscrpt.sql,也是成功。因为两种方式报的错误都是一样的。

至此表空间从linux ASM磁盘组迁移到win FS系统下。
遇到的问题以及注意项
1.源数据库表空间的名字不能为test,因为test是RMAN的关键字。
RMAN> transport tablespace test tablespace destination "/s01/dd" auxiliary destination "/s01/dd";

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-00558: error encountered while parsing input commands
RMAN-01009: syntax error: found "test": expecting one of: "double-quoted-string, identifier, single-quoted-string"
RMAN-01007: at line 1 column 22 file: standard input
http://docs.oracle.com/cd/B19306_01/backup.102/b14194/rcmcomma001.htm#RCMRF909有说明
2.如果两个平台的字节顺序不一致,可以使用rman进行转化。
RMAN> convert tablespace tt1 to platform 'Microsoft Windows IA (32-bit)' format '/tmp/%N_%F';   
RMAN> convert datafile '/tmp/BOOKS_5' db_file_name_convert '/tmp/BOOKS_5','/tmp/books01.dbf';  
3.创建传输集过程报错如下
ORA-19502: write error on file "/s01/dd/HJJ/datafile/o1_mf_system_9kj14qc1_.dbf", block number 82816 (block size=8192)
ORA-27072: File I/O error

Additional information: 4
Additional information: 82816

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of transport tablespace command at 03/05/2014 21:18:59

RMAN-06136: ORACLE error from auxiliary database: ORA-01180: can not create datafile 1
ORA-01110: data file 1: '+DATA_DG/hjj/datafile/system.260.837919351'
因为创建传输集时,需要一个临时目录/s01/dd,会将备份集中的datafile,onlinelog,controlfile存放于此,所以要提前估算好空间。
这个错误就是因为空间不足引起的。

 

思考:利用RMAN跨平台传输表空间,个人挺麻烦的,首先要备份全库,归档日志和控制文件,最后还得用imp/impdp进行导入。那为啥不直接使用imp/expdp导入,简单问题复杂化了,目前还不知道这种方式的优势在哪。
