这里看到rman只是sql语句中的select和desc用法
rman分割数据文件增强
[*] RMAN>CONFIGURE DEVICE TYPE DISK PARALLELISM 3;
[*]
[*] old RMAN configuration parameters:
[*] CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET;
[*] new RMAN configuration parameters:
[*] CONFIGURE DEVICE TYPE DISK PARALLELISM 3 BACKUP TYPE TO BACKUPSET;
[*] new RMAN configuration parameters are successfully stored

在12C之前的版本，ORACLE 11GR2只是对于全备的备份集备份(非增量,非copy备份方式)方式支持数据文件分割备份功能,对于11.2之前的版本均不支持该功能.在12C中rman可以支持对于全备,增量备份,copy备份全部支持分割数据文件备份(CONTROLFILE,SPFILE不支持)。
