Subject [jira] Updated: (DERBY-1275) Provide a way to enable client tracing without changing the application
Date Fri, 13 Oct 2006 18:22:36 GMT
     [ http://issues.apache.org/jira/browse/DERBY-1275?page=all ]

Mike Matrigali updated DERBY-1275:
----------------------------------


I think as a short fix you should just add the 2 system properties that kathey proposes. 
This seems like a reasonable short term fix to allow debugging at a client site without having
to have access to
their source code and needing to recompile their source to enable some debug tracing.

> Currently  the client tracing can be enabled by  setting attributes on the client url,
setXXX methods on the DataSource or calling DriverManager.setLogWriter(), but it often cannot
be enabled in a deployed client application  because all of these API's require modification
of the application or its configuration files.
> It would be good to have a global way to turn on client tracing.  A system property pointing
to a property file is  one possibility but probably not ideal because of the impact in class
loader contexts.    I am not sure what the other possiblities are,
