Agentd problem with UserParameter

[Kso]

I try to use parameter to monitor Oracle10g using zabora script(thanks to the provider).
But I encountered problem with the Agent Daemon:
The Daemon is running under Zabbix User (version 1.5.3 linux 2.6.18 source compiled).

When I start the daemon, i can see in the log file of the agent that the parameters are taking into account:
5213:20080813:111338 cfg: para: [UserParameter] val [oracle[*],/usr/local/zabbix/script/zabora $1 $2]
5213:20080813:111338 Accepted configuration parameter: 'UserParameter' = 'oracle[*],/usr/local/zabbix/script/zabora $1 $2'

With User Zabbix Identity, i can run the script:
./zabora usercount
569

When I try to ask the agentD for this parameter it does not recognize it:
/usr/local/zabbix/sbin/zabbix_agentd -c /etc/zabbix/zabbix_agentd.conf -t oracle[usercount]
oracle [m|ZBX_NOTSUPPORTED]

When I try to ask the agent for the same parameter and same config file, it's ok:
/usr/local/zabbix/sbin/zabbix_agent -c /etc/zabbix/zabbix_agentd.conf -t oracle[usercount]
oracle[/usr/local/zabbix/script/zabora usercount ] [t|584]

Does anybody know what can be the problem ?
Thanks for help !!

I have the same problem. Suggestion is:
In example was UserParameter=oracle[*],/home/zabbix-1.8/zabora /$1 /$2
I change it to
UserParameter=oracle[*],/home/zabbix-1.8/zabora $1 $2
