oracle8i rman 分配channel的问题

hzmark

oracle8i rman问题(windows2000 advance)

在RMAN中给ORACLE8I分配备份设备类型出错
allocate channel ch00 type "SBT_TAPE";

提示不能识别ch00

另外想问问,8I的默认备份设备类型是如何设置的?

在ORACLE9I里面是可以分配的

我是用NBU5.1通过网络备份ORACLE8I到带库上,在备份脚本的.out的文件中的提示有
RMAN-03007: retryable error occurred during execution of command:allocate
RMAN-07004:unhandled exception during command excution on channel ch00
RMAN-10035:exception raised in RPC:ORA-19554:error allocationg device,device type:SBT_TAPE,device name
ORA-19557:device error,device type:SBT_TAPE
ORA-27000:skgfqsbi:failed to initialize storage sbusystem(SBT) layer
ORA-19511:SBT error :4110 errno=0,BACKUP_DIR environment variable is not set
RMAN-10031:ORA-19624 occurred during call  to DBMS_BACKUP_RESTORE DEVICEallocate

NBU备份ORACLE的脚本在备份ORACLE9I的时候都是正常的,我觉得是不是8I在分配备份设备时RMAN命令不一样而导致allocate 设备不成功
