JAS Debug Logging?

I'm really tearing my hair out on this one: We are running Xe SP16 on Oracle 8.1.7. The JAS server generally is not writing anything useful to the debug log. Mostly all we get is a bunch of lines similar to these:

2003-12-01 15:35:33.735 [Thread-7-JdbcPoolCleaner] JDBC : INFO: Clean of connection pools completed. 0
bad connections replaced
2003-12-01 15:35:34.105 [Thread-8-CacheManager-Deamon] JAS : clean cache group -> JDBCProxy

However occasionally, for no discernable reason, it suddenly starts logging actual useful stuff, such as sql queries generated etc. I really need that stuff right now, but have no idea how to make it happen, nor why it sporadically does happen.

Any tips greatly appreciated!

I'm not sure if some of the debug functionality are in SP16 but here is one for SP20 and above:

in jas.ini

[LOGS]
Debug=TRUE
log=C:\Program Files\JDEdwards\JAS\EA_JDEdwards_1.ear\webclient.war\logs\jas.log
debuglog=C:\Program Files\JDEdwards\JAS\EA_JDEdwards_1.ear\webclient.war\logs\jasdebug.log
# JDBC Trace (in stdout)
jdbcTrace=TRUE

rtdebugTrace=TRUE
rtlog=C:\Program Files\JDEdwards\JAS\EA_JDEdwards_1.ear\webclient.war\logs\rt.log
rtdebug=C:\Program Files\JDEdwards\JAS\EA_JDEdwards_1.ear\webclient.war\logs\rtdebug.log
rtlogType=All
#or =BSFN|TableIO|SYSFUNC|MISC|ER|EVENT|THREAD (any combination).

stdout=C:\Program Files\JDEdwards\JAS\EA_JDEdwards_1.ear\webclient.war\logs\stdout.txt
stderr=C:\Program Files\JDEdwards\JAS\EA_JDEdwards_1.ear\webclient.war\logs\stderr.txt

#JasDBLogging is the level for JAS DB logging.
