{
allocate channel ch00 type 'sbt_tape';
SEND 'NB_ORA_POLICY=test,NB_ORA_SERV=inms_back,NB_ORA_CLIENT=ts_oss_bak,NB_ORA_SCHED=Default-Application-Backup';
backup incremental level 0 database
format 'ctrl%t%s.%p';
}

偶写的脚本如下
{
allocate channel ch00 type 'sbt_tape';
SEND 'NB_ORA_POLICY=test,NB_ORA_SERV=inms_back,NB_ORA_CLIENT=ts_oss_bak,NB_ORA_SCHED=Default-Application-Backup';
backup incremental level 0 database
format 'ctrl%t%s.%p';
}
那位高手给指点迷津，这里不胜感激呀！
