Thank you by he information . I have another question
When the comunnication channel is broken i get the next mistake
Error: ORA-03114:
not connected to ORACLE
If continuous carrying out querys always I get this mistake .
When I restart IIS Server , or when I do not execute the consultation by a time the mistake disappears
But I need a form to eliminate the conexion that has broken himself so that disappear the error, like I can do that??
Thank you
