ORACLE 12C RMAN 功能增强

在ORACLE 12C中对rman的功能有了不少增强,在以前的文章中写过RMAN RECOVER TABLE功能,这里另外补充rman增强的两个小功能(sql语句和数据文件分割)
数据库版本

SQL>  select * from v$version;

rman对sql语句支持增强

using target database control file instead of recovery catalog

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)
