I still think a simple kludge is to pipe to a program. In catalina.sh, change: >> "$CATALINA_BASE"/logs/catalina.out 2>&1 & to | more 2>&1 &
In place of more - put your favorite log rotation script.
For windows - it might be a bit trickier.

I agree that developers should use good coding practices. But they don't. So as a sys-admin or an ops guy you have to rotate that file simply because tomcat creates it. If it wasn't there developers couldn't use it and ops wouldn't have to rotate it.
My initial confusion was because it is basically a nohup.out file and if you move the descriptor tomcat will write into no mans land. This is typical of a nohup.
It would be great if in a future release tomcat did the rotation internally or did away with the file altogether.

I have mixed feelings on catalina.out.
On one hand it should be allowed to rotate because it does get written to.
OTOH - After the startup message - nothing really should be written to it without making an effort to do so. So only badly written code which uses System.out/err will be the victim. This is the incentive to use a real logging package. Allowing rotation allows reward of bad code.
OTOH - Adapting the startup scripts should be easy for a user to fix their bad code in that they can pipe to a simple log rotation program instead of a file.

Howdy, It seems you're right -- I hadn't looked at the code for a while.
This is why I suggested tomcat use the log4j file rollover mechanism, which is very robust. But I didn't get much positive feedback, and I certainly don't have the bandwidth to do it myself right now...

what mechanism is that?
It looks like the logs are being held by an open file descriptor, so rotating the catalina.out will just stop logging after the first
rotation,
since you cause an IOException in Tomcat.

Howdy, Why not use the nightly rollover mechanism used for servlet logs, localhost logs, etc. also for catalina.out?

I was going to experiment with it next week. It would be nice to do
it
within Tomcat and stay away from the Unix-y stuff. That way it
would
also
work for the windows users.
I have a feeling the Unix-y stuff will have to suffice for a bit.

did anyone figure out how to rotate this bad boy and the
localhost_log
without shutting down tomcat?
