SqlDisconnect fails permanantly when database goesdown

[sakalk]

Hi,
I connect to Oracle using SQLBase - SqlConnect, then at the end of application call SqlDisconnect. It all works fine but if the database goes down suddenly or my network connection has failed then the SqlDisconnect comes back with error. And there is no way out. Even when the database comes back the handle is invalid. So is there a way to recover it ? I mean sort of forcefully close this handle? Unless I close it I cannot open another too! Any comments appreciated.

Thanks
SaKa
