这些个存放目录：闪回区目录，adr目录，审计日志目录，?Oracle-managed 数据文件目录 等等，一定要注意啊
------------这里解释使用类上述命令执行后的日子输出，来理解使用上述命令初始化备库的原理：
$rman target sys/sys@chicago auxiliary sys/sys@boston
connected to target database: CHICAGO (DBID=761464750)
connected to auxiliary database:?CHICAGO (not mounted)
RMAN> run {
allocate channel prmy1 type disk;
allocate channel prmy2 type disk;
allocate channel prmy3 type disk;
allocate channel prmy4 type disk;
allocate auxiliary channel stby type disk;
duplicate target database for standby from active database
spfile
? parameter_value_convert 'chicago','boston'
? set db_unique_name='boston'
? set db_file_name_convert='/chicago/','/boston/'
? set log_file_name_convert='/chicago/','/boston/'
? set control_files='/u01/app/oracle/oradata/control01.ctl'
? set log_archive_max_processes='5'
? set fal_client='boston'
? set fal_server='chicago'
? set standby_file_management='AUTO'
? set log_archive_config='dg_config=(chicago,boston)'
? set log_archive_dest_2='service=chicago ASYNCvalid_for=(ONLINE_LOGFILE,PRIMARY_ROLE) db_unique_name=chicago'
;
}
using target database control file instead of recovery catalog
allocated channel: prmy1 ? ? ? ? ? ? ? ? ? ?---------这个就不多说了：分配通道
channel prmy1: SID=147 device type=DISK
allocated channel: prmy2
channel prmy2: SID=130 device type=DISK
allocated channel: prmy3
channel prmy3: SID=137 device type=DISK
allocated channel: prmy4
channel prmy4: SID=170 device type=DISK
allocated channel: stby
channel stby: SID=98 device type=DISK
