Where does Tomcat log the logAbandoned information?
Hello,
I have enabled the *logAbandoned* property as follows (in Spring):
<property name="maxActive" value="2"/>
<property name="logAbandoned" value="true"/>
<property name="removeAbandoned" value="true"/>
I know for certain it is taken into account by Tomcat but *I just can't
figure out where the information is logged*.
It seems to be a recurring question on the web but I was not able to find
the answer to it.
Can anyone please informed advice?
Regards,
Julien.

AFAIR DBCP doesn't use a log framework and instead uses writing
System.out. So catalina.out is your friend in this case.

Any idea what the logs should look like? Any sample?

Actually, you're right this is DBCP inside your app - so you might need
to look in an app log if there is one.

Maybe you're not waiting long enough or there's no abandoned connections
to be logged.

Hi Pid,
Is there any other config I need to add (for instance to log4j.properties)
in order for the logAbandoned logging to occur?
I see nothing in stdout nor in the tomcat logs...

It will be logged to standard out, catalina.out or catalina.{date}.log
In your case, the timeBetweenEvictionRunsMillis check will happen every
1800000 millis, which is 1800 seconds, which is every 30 minutes for
connections that have been idle the same period, which may mean that
they don't qualify for eviction for over 30 mins, which in turn would
mean the next check - 30m later.
Maybe you should reduce that number during testing.
