Sun Java System Application Server Enterprise Edition 8.2 Administration Guide

Log Records

The Application Server uses the Java 2 platform Logging API specified in JSR 047. Application Server logging messages are recorded in the server log, normally found at domain-dir/logs/server.log.

The domain-dir/logs directory contains two other kinds of logs in addition to the server log. In the access subdirectory are the HTTP Service access logs, and in the tx subdirectory are the Transaction Service logs. For information about these logs, consult the Administration Console online help.

The components of the Application Server generate logging output. Application components can also generate logging output.

Application components may use the Apache Commons Logging Library to log messages. The platform standard JSR 047 API, however, is recommended for better log configuration.

Log records follow a uniform format:

[#|yyyy-mm-ddThh:mm:ss.SSS-Z|Log Level|ProductName-Version|LoggerName|Key Value Pairs|Message|#]

For example:

system.core|_ThreadID=13;|CORE5004: Resource Deployed: 

In this example,

You can use the com.sun.enterprise.server.logging.max_history_files system property to limit the number of rotated log files for both access logging and the server log. The property specifies the maximum number of access log files to keep, starting with the most recent ones.

In the Admin Console, access the config/server that this system property needs to be set for. On the command line, use the create-jvm-option command.
