今天在论坛发贴问rman的set nocfau表示什么？

按照bluemoon0083表示：估计是隐藏选项，no controlfile autobackup的意思
自己不做测试了，摘录如下：
RMAN> configure controlfile autobackup on;
new RMAN configuration parameters:
CONFIGURE CONTROLFILE AUTOBACKUP ON;
new RMAN configuration parameters are successfully stored
RMAN> show controlfile autobackup;
RMAN configuration parameters for database with db_unique_name XXXXX are:
CONFIGURE CONTROLFILE AUTOBACKUP ON;
RMAN> backup archivelog sequence 1;
