2010 has been an exciting year for the Tomcat Expert community site. Created by the Apache Tomcat Experts at SpringSource, Tomcat Expert was launched in March to improve the adoption, performance and value of Apache Tomcat for enterprise users. After almost ten months of operation, we’ve been able to provide you with content from Tomcat Expert Contributors weighing in on top Apache Tomcat news and topics, including several relating to June's release of Tomcat 7.0.0 Beta, the first Tomcat 7 release. As the year winds down, we've put together a list of the most popular blog posts of the year. Additionally, we're asking you to tell us what topics you'd like to see covered more in 2011 with a content request form below.
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.
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.
In this webinar, Apache Tomcat committers Mark Thomas and Filip Hanik discuss performance tuning Apache Tomcat for your production environment. This webinar focuses on Tuning Tomcat and the JVM to correctly handle your application including usage patterns, hardware and network topology. You’ll learn when and how to apply the different tuning and configuration options as well as understanding load balancers and how they can impact your configuration settings. Also discussed: the impact of clustering and replication on your environment.
As Tomcat takes on greater roles in enterprise environments, proper tuning and optimization becomes “top of mind” for all stakeholders as well as IT developers and operations teams. Key approaches and processes are laid out to help understand the process to ensure Tomcat runs successfully and with performance.
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.
Tomcat 4.1
=========
In Tomcat 4.1, the logVerbosityLevel attribute for the Logger element can be used to set the log level. FATAL, ERROR, WARNING, INFORMATION, and DEBUG are the valid values. The default setting is at the WARNING level.
Tomcat 5.0
=========
In Tomcat 5.0, it can be changed through commons logging or log4j. Log4j is recommended as it has greater flexibility. In doing so:
Since starting as a reference implementation by Sun Microsystems, Tomcat has undergone quite a history in the past 10 years with an average of one release per month. The history, versions, development lifecycle, and an in-depth look at key features in the new release are shared with other key insights on the new release and throughs on upgrading.
