Could you tell me what's the meaning of the logfile-path and log-level?

Question

we are running an productive xml database. but it is not stable now. Sometime it would report resource conflict error while you access xmldb via http protocol. I read the database logs and listener logs, but no abnormal message could be found. So, I want to find more information from the xmldb logs. While I run select DBMS_XDB.cfg_get().getclobval() from dual, I found that there are several logfile-path and log-level tags and I guess that these would be xmldb logs. Does anyone know what's the meaning of these tags?

I wondered about that one often too. I didn't have a chance yet to investigate (but maybe Mark will elaborate a little here), my guess is that it / or will be a possibility to enable tracing regarding the protocols or servlets.
Though It look like if you enable it it will trace to the XML file defined in the xdbconfig.xml. I also guess that (because there is also a XSD counterpart) that one could create an resource that streams the errors into a XDB ftp or http or ... xmltype table based on these settings.
This would be great because it would mature the protocol server regarding functionality. You could enable the tracing and see what happens. Until now the documentation doesn't give much extra insight...
