rman连接cdb，备份整个数据库
run{
allocate channel C1 device type disk format '/home/oracle/backup/full_db_%U';
backup database include current controlfile plus archivelog ;
release channel C1 ;
}
crosscheck backupset;
delete noprompt obsolete;
或者
backup database include current controlfile format '/home/oracle/backup/full_db_%U' plus archivelog format '/home/oracle/backup/full_db_%U';
