Hi Alexander,
I tried "vcops-admin restart" and it worked !
but I am doing a lot of modifications & tests on a custom report (no official doc ? 
), so each time I make a change, I will have to restart vcops services ?
it is quite a rough operation to perform it 40x a day.
The "/usr/lib/vmware-vcops/user/conf/install/vcops-viewsreports.sh xxx.xml update" is not enough ?
thks for your help,
vinny
