Thanks for the explanation, Marc. That helped.

If I understand it properly, you recommend:

class A:

       def __init__():
             ...
             self.connection = DriverConnect()
             ...

objA = A()

And call

stormedDB =  StormifyDatabase(objA)


If I have mis-understood. can you please point me to any example
snippets which I can look at and design accordingly.

I would like to do that, the but the point is:

user_script.py - has db_api = <ClientSideObject...>
Now, I pass this object to storm ORM and the entire application uses
the stormified object. Returns the value.
I have tried doing .close() on __del__() method of the class where I
am opening the ClientSideObject, but still after  a "couple of
successful executions" (without any error message in the Server.log)
I end up at:
 File "mx/ODBCConnect/Common/ProxyObjects.py", line 675, in __call__
  File "mx/ODBCConnect/Client/ServerSession.py", line 614, in methodcall
  File "mx/ODBCConnect/Client/ServerSession.py", line 423, in _response
  File "mx/ODBCConnect/Common/ProxyObjects.py", line 1191, in process_response
InterfaceError: Connection limit exceeded. Your license allows 20
physical database connections.

called from the very same __del__() method.

I might share the code at [email protected] for further suggestions.

Thank you,
Senthil
