Subject [jira] Commented: (DERBY-1275) Provide a way to enable client tracing without changing the application
Date Fri, 13 Oct 2006 18:12:36 GMT
    [ http://issues.apache.org/jira/browse/DERBY-1275?page=comments#action_12442076 ] 
            
Mamta A. Satoor commented on DERBY-1275:
----------------------------------------

There have been discussion on this jira entry for 2 possible solutions. 
1)One is to implement the way the server does, ie using something equivalent to derby.home
on the client side. 
2)The other is to explore JMX. 

I don't have knowledge about JMX but seems like JMX could be used not just for the properties
associated with this Jira entry but also for the properties in general supported by Derby.
If that is the case, then may be it should be taken on as a feature by itself and for now
implement this Jira entry in a fashion similar to what Derby server already does. Any thoughts
on this, or other proposed solutions?

> 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,
