Oracle Transport Tablespace by RMAN

前面测试了使用传统的方法传输表空间需要对表空间进行离线,由于生产库一般不能离线操作,所以传统方法存在一定的局限性.
使用RMAN可以在保证表空间在线的状态下进行传输.

(1)完全备份数据库
RMAN> backup database plus archivelog;

(2)使用RMAN在源库创建4个文件.但该步骤出错了,如下.

RMAN> transport tablespace tsmgmt_ts4 tablespace destination '/oracle/home/test/td' auxiliary destination '/home/oracle/test/ad';

RMAN-05026: WARNING: presuming following set of tablespaces applies to specified point in time

注意在使用RAMN进行生成TTS metdata和数据文件时,当备份文件放在ASM上时容易出错,放在本地磁盘可以成功;另外需要控制文件和TTS表空间数据文件的备份.

(3),另外当源,目标库的平台不同时(32->64位),RMAN也可以起到作用,RMAN可以用来对数据文件进行转换.

查看源和目标平台后,如果两者不一致,可以使用RMAN在目标库将拷贝过来的数据文件(/home/oracle/32)进行转换.

RMAN> convert datafile '/home/oracle/32/tsmgmt_ts4.ora'
      to platform 'Linux IA (64-bit)'
      from platform 'Linux IA (32-bit)'
      db_file_name_covert='/home/oracle/32','/home/oracle/64';

或者拷贝之前进行表空间的转换,但数据文件很大的表空间会很慢.

RMAN> convert tablespace tsmgmt_ts4 to platform 'Microsoft Windows IA (32-bit)' format '/home/oracle/tsmgmt_ts_ms32.dbf';
