Stderr and Stdout Log Rotation on Tomcat 6.0 on Windows
Hello all, I’m running a Tomcat service on Windows and I’m having some minor issues with the logging mechanism. I've been researching for weeks now, read every FAQ, user forum and article but no one seems to have any clue on this. I use 64-bit Tomcat 6.0.39 as a Windows service on Windows 2008 R2 x64Standard. Tomcat keeps writing to the same stdout and stderr log files without any log rotation until the service is restarted. Because of this, the stdout and stderr log files become quite large in time and it becomes difficult to open/read logs. My aim is to never restart the Tomcat service until it isreally necessary, so this makes log rotation quite crucial. The Tomcat process won’t release the log files until the Tomcat service is restarted. I was unable to use 3rd party tools for logrotation as stdout and stderr files are locked by the process. While this Tomcat log rotation is quite simple on Linux, there seems to be no simple way to do it on Windows. I tried every command to force JULI to rotate these two files based on size or date but it was fruitless. I tried to force Log4j to take over the logging mechanism but stdout and stderr still seem to act on their own, probably due to Tomcat’s internal mechanisms. Btw webapp application logs rotate just fine. Have you had any experience with stdout/stderr log rotation on Windows Tomcat? If you have the time, it’d be great if you could share yourthoughts..

Hi Kristof, tell your developer to use a logging framework instead of System.out You can't get rid of stoud and stderr log files, but they should be empty - most of the time. cheers, Björn On 20 Aug 2014, at 13:51 , Kristof Can Bilen cankris...@yahoo.com.INVALID wrote: Hello all, I’m running a Tomcat service on Windows and I’m having some minor issues with the logging mechanism.

IIRC, the Windows Service is basically procrun which can close and re-open the log files that it writes. ...don't ask me how to send a signal on Windows, though ;) - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1 Comment: GPGTools - http://gpgtools.org iQIcBAEBCAAGBQJT9O7wAAoJEBzwKT+lPKRYHCwQALIU+MpqdNWESbHnVEFZbh3C JplTtoofvSfPTH0mv+3xcsrCmYKbyV6zrCTpwDXVFqdIspLVIY2GhoADP9bUMJjN Wjf9nY7Pce0aaufgS5m49pQLyIrRXJr2QgyVN1C9NbVaS/hFkjnGcfb4HKuoqgvm VmNnBnKrcpFRs0Dad6V+Wr7xksm70Bx84Um4viIm6PcTnoL43f9KigOd2DdYiK1z 8q8dzseSr7A+rWSoqJC8DF+JpZMsptyZuXOUUI3AjH51Pc942oYSzke5qNc3/ChJ I57ywbmPXGm4GLK9tBYe/kXP3xwrutZwlDyQ7c8Et0wdLsAuTlUx94FGhBgntTMb PUZMQRMZy07NO3HOWCPalwCN1QpYnNN/c3mfTdMSraX2Ch+yHXkqVWDtG7Eyia39 eJtRpcoLufK35fhtd6NGNmWTNn4HzXqhjKiZRuF9vu9WNLdSpgdpBw4YWNkIUc0E mGoeesrvX5DHIcGkx8MPyfutsKHIOvjv1YR5WXox7SKtbpZhhtW4OPhmd3+gNQQZ Tjbw2RuwS0eNROXUEM+G9w+RMsBBUCfe9blpY8joWJQWsu1Rh3D7TwVfM8F+f3ym L4DYyMgmjD0dVMeum+xLlGZQ5LYgIjMZ4OSEUA/hr9khzFUgXNp2qY9Ye/mkwc4g SlM6cR0GqYcWSFaSCcro =xpsv -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
