Subject [jira] Commented: (DERBY-293) Correlate client connection with embedded connection
Date Fri, 19 Aug 2005 23:19:57 GMT
    [ http://issues.apache.org/jira/browse/DERBY-293?page=comments#action_12319439 ] 

Kathey Marsden commented on DERBY-293:

With David's change to embedded connection toString (DERBY-412), the Client connection   toString()
method could print the same DRDAID.

 I am worried that if we use toString() for this, the output will be overly long and complicated;
also, over a period of time the same embedded connection may be associated with multiple client
connections, resulting in a changing toString() value for the embedded connection.  This seems
problematic if we are intending toString() to uniquely identify a connection for the lifetime
of the connection -- this would be a good goal to have as it would enable us to do some useful
debugging using the VTIs.
