[20160427]rman tag format标识.txt

--昨天别人问一个关于rman很奇怪的问题,就是能否实现给全备以及archive加不同的tag.
--当然最简单的方法就是分开执行,这样就没有问题.
--我们生产系统就是分开写的,例子:

backup as compressed backupset full database filesperset=1
    tag="full $current"
    include current controlfile
    format "$BACKUP_HOME/fulls/${DB_NAME}_%d_%T_%s_full" ;

sql 'alter system archive log current ';

backup as compressed backupset archivelog all
    tag="archivelog $current"
    not  backed up 1 times
    format '$BACKUP_HOME/archives/${DB_NAME}_%d_%T_%s_archive' ;

--实际上可以写成:

RMAN> backup as compressed backupset full database tag='full 20160427'  plus archivelog tag="archivelog 20160427" ;
...

RMAN> list backup summary;
