关于RMAN的配置信息存储和控制文件的关系

没有使用catalog时，rman中的所有配置信息都会记入在 控制文件中

控制文件中dump出来的信息：

***************************************************************************
RMAN CONFIGURATION RECORDS
***************************************************************************
 (size = 1108, compat size = 1108, section max = 50, section in-use = 2,
  last-recid= 4, old-recno = 0, last-recno = 0)
 (extent = 1, blkno = 91, numrecs = 50)
CONTROLFILE AUTOBACKUP:ON recno=1
CHANNEL:DEVICE TYPE DISK FORMAT   '/home/oracle/backup/%U' recno=2
