使用TDPO通过调度自动备份ORACLE9I权限失败，求助

各位大侠大家好！小弟现在遇到一点问题想请教。
我的TSMserver是6.2的使用TDPO备份oracle9i  客户端的环境是WINDOWS2003
我的配置如下：
dsm.opt：
COMMmethod           TCPip
TCPPort                1500
TCPServeraddress    192.168.1.235   
NODENAME            SERVER_ORA
PASSWORDACCESS      GENERATE
MANAGEDSERVICES    SCHEDULE
tdpo.opt:
DSMI_ORC_CONFIG    D:Program FilesTivolitsmAgentOBAdsm.opt
DSMI_LOG           D:Program FilesTivolitsmAgentOBA
调用RMAN脚本：
rman target xxx/system@ORAWEB CMDFILE 'D:Progra~1TivoliTSMAgentOBAorafull.rman' LOG 'D:Progra~1TivoliTSMAgentOBAlogsrman_fullbackup_%DATE:~0,4%%DATE:~5,2%%DATE:~8,2%".log'
RMAN脚本：
run{
set controlfile autobackup format for device type 'sbt_tape' to '/ctl_%d_%F';
allocate channel t1 type 'sbt_tape' parms 'ENV=(tdpo_optfile=D:Program FilesTivolitsmAgentOBAtdpo.opt)';
backup incremental level 0 database format='LEV0_%d_%t_%U' diskratio=0 include current controlfile;
sql 'alter system archive log current';
backup archivelog all skip inaccessible format 'log_%d_%s_%p_%u';
delete noprompt archivelog until time 'sysdate - 7';
release channel t1;
}
allocate channel for maintenance type 'sbt_tape' parms 'ENV=(tdpo_optfile=D:Program FilesTivolitsmAgentOBAtdpo.opt)';
crosscheck backup;
crosscheck archivelog all;
report obsolete;
delete noprompt obsolete recovery window of 14 days;
delete noprompt expired backup;
release channel;
以上手工在客户端里面执行脚本都没问题，就是使用DSMCAD守护进程进行自动调度的时候报出一下错误：

什么地方没有配置对么？
