Knowledge Base : Rotating catalina.out log files

posted by SpringSource on June 28, 2010 09:58 AM

It is possible to rotate the catalina.out log, by using a log rotation program like rotatelogs or cronolog.

It is possible to rotate the catalina.out log, but it is not controlled by the standard logging.properties or log4j.properties files.

The catalina.out log is stderr and stdout piped to a file. If you want to rotate this log file you will need to use a log rotation program like rotatelogs or cronolog. Then just pipe to the log rotation program rather than the file.

Knowledge Base : Securing Apache Tomcat for Enterprise Use

posted by SpringSource on April 8, 2010 12:06 PM

For development and operations teams, a presentation that covers various security configuration options available in Apache Tomcat and SpringSource tc Server.

A default Apache Tomcat installation is secure but each installation environment is different and may have additional security requirements. This presentation will examine the security configuration options available in Apache Tomcat and SpringSource tc Server, when to use them (and when not to use them) and the threats they might help mitigate. The rationale behind having resource passwords (e.g. for database access) in clear text in server.xml will also be discussed.

Knowledge Base : How to configure log rotation in Apache Tomcat 5.5 and 6.0 using the Juli logging package

posted by SpringSource on March 18, 2010 11:46 PM

How to enable file rotation to periodically purge older log files and clear space using the default juli internal logging for Apache Tomcat.

By default, Apache Tomcat dies its internal logging through juli. The quantity of information stored in the log files on any server can quickly grow to be quite large. For instance, the access log file typically grows 1 MB or more per 10,000 requests. Therefore, it may be necessary to periodically rotate the log files by moving the files or deleting the existing logs to free up space on the server and allow for more efficient searching through logs. This cannot be done while the server is running, because Apache Tomcat will continue writing to the old log file as long as it holds the file open.
