Target DB / RMAN Client: 11.2.0.1.0
1. 当CONFIGURE CONTROLFILE AUTOBACKUP OFF;时，仅备份数据文件1（system01.dbf）时会自动备份控制文件；
2. 当CONFIGURE CONTROLFILE AUTOBACKUP ON;时，备份任意文件（数据文件/归档日志）都会自动备份控制文件。

1. Backing Up Control Files with RMAN
http://docs.oracle.com/cd/E11882_01/backup.112/e10642/rcmbckba.htm#i1009642
You can back up the control file when the database is mounted or open. RMAN uses a snapshot control file to ensure a read-consistent version. If the CONFIGURE CONTROLFILE AUTOBACKUP command is set to ON (by default it is OFF), then RMAN automatically backs up the control file and server parameter file after every backup and after database structural changes.
If the autobackup feature is not set, then you must manually back up the control file in one of the following ways:
Run BACKUP CURRENT CONTROLFILE .
Include a backup of the control file within any backup by using the INCLUDE CURRENT CONTROLFILE option of the BACKUP command.
Back up data file 1, because RMAN automatically includes the control file and server parameter file in backups of data file 1.
Note:
If the control file block size is not equal to the block size for data file 1, then the control file cannot be written into the same backup set as the data file. RMAN writes the control file into a backup set by itself if the block size is different. The V$CONTROLFILE.BLOCK_SIZE column indicates the control file block size, whereas the DB_BLOCK_SIZE initialization parameter indicates the block size of data file 1.
1. 当CONFIGURE CONTROLFILE AUTOBACKUP OFF;时，仅备份数据文件1（system01.dbf）时会自动备份控制文件；
2. 当CONFIGURE CONTROLFILE AUTOBACKUP ON;时，备份任意文件（数据文件/归档日志）都会自动备份控制文件。

1. Backing Up Control Files with RMAN
http://docs.oracle.com/cd/E11882_01/backup.112/e10642/rcmbckba.htm#i1009642
You can back up the control file when the database is mounted or open. RMAN uses a snapshot control file to ensure a read-consistent version. If the CONFIGURE CONTROLFILE AUTOBACKUP command is set to ON (by default it is OFF), then RMAN automatically backs up the control file and server parameter file after every backup and after database structural changes.
If the autobackup feature is not set, then you must manually back up the control file in one of the following ways:
Run BACKUP CURRENT CONTROLFILE .
Include a backup of the control file within any backup by using the INCLUDE CURRENT CONTROLFILE option of the BACKUP command.
Back up data file 1, because RMAN automatically includes the control file and server parameter file in backups of data file 1.
Note:
If the control file block size is not equal to the block size for data file 1, then the control file cannot be written into the same backup set as the data file. RMAN writes the control file into a backup set by itself if the block size is different. The V$CONTROLFILE.BLOCK_SIZE column indicates the control file block size, whereas the DB_BLOCK_SIZE initialization parameter indicates the block size of data file 1.
