brtools ok but db13 ko

Hi experts,

I have a problem; after an upgrade; I can execute all commands by brtools but not with db13.

Appear this error:

24.03.2013 13:42:12 Execute logical command BRCONNECT On host srv-db

24.03.2013 13:42:12 Parameters: -jid CHECK20130324134211 -u / -c -f check

24.03.2013 13:42:12 Invalid trace level as argument

24.03.2013 13:42:12 BR0801I BRCONNECT 7.20 (25)

24.03.201313:42:12BR0155E No value found for option '-f'

24.03.2013 13:42:12 BR0280I BRCONNECT time stamp: 2013-03-24 13.42.12

Any idea?

I try with check db, update statistics and always appear "No value found for option"

Thanks in advance,

Regards,
