[jira] Commented: (DERBY-1275) Provide a way to enable client tracing without changing the application

    [ https://issues.apache.org/jira/browse/DERBY-1275?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12469255 ] 

Mamta A. Satoor commented on DERBY-1275:
----------------------------------------

I have added a page to Derby wiki for Derby's undocumented behavior. Goto page http://wiki.apache.org/db-derby/ and click on UndocumentedDerbyBehavior: under Derby Usage Information. It will take you to the page where the 2 new jvm properties are described with a pointer to the Jira entry. Please let me know if you have any feedback on the contents of the page and how the page is connected from the Derby wiki page.

> 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,
