Hi Yogesh,

there are two parts to your question.

In order to update module and the database fields on startup of the OpenERP server you can indeed use the -u parameter. In order to update all modules use "-u all" or jst to update module xxx use "-u xxx".

A possible reason you cannot see your module is that the Settings->Modules->Apps is that this only shown Apps (modules approved by OpenERP themselves). In order to see all modules look in Settings->Modules->Installed Modules and then delete the filter (top left) "Installed".

Hope this helps.
