200 Getting Started with WebSphere Application Server Community Edition Both the install and un-install log files are located at directory where is the user primary directory in the operating system. In Windows, is in C:\Document and Settings\ directory; while in Linux and UNIX it is in /home/ directory. Table 11.2 below provides the file names for the install and uninstall log files and their description. Log file name wasce_install_information.txt wasce_install_YYYY-MM-DD_HH- MM-SS.log wasce_uninstall_information.t xt wasce_uninstall_YYYY-MM- DD_HH-MM-SS.log Description Records every variable being revoked during installation. Records system variable settings and JVM information during installation, where YYYY- MM-DD_HH-MM-SS is a timestamp. Records every variable being revoked during uninstallation. Records system variable settings and JVM information during uninstallation, where YYYY-MM-DD_HH-MM-SS is a timestamp. Table 11.2 - File name for install and uninstall logs 11.5.2 Server log Messages from the server, applications and deployment are logged to the /var/log/server.log file. The file location, name, and the log levels can be changed by editing the /var/log/server-log4j.properties file. For example, if you would like to change the root log level to DEBUG, you can change the log4j.appender.FILE.Threshold property in the server-log4j.properties to this value as shown in Listing 11.2. log4j.rootLogger=DEBUG, CONSOLE, FILE log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender log4j.appender.CONSOLE.Threshold=${org.apache.geronimo.log.ConsoleLogLe vel} log4j.appender.CONSOLE.Target=System.out log4j.appender.CONSOLE.lausert=org.apache.log4j.PatternLausert log4j.appender.CONSOLE.lausert.ConversionPattern=%d{ABSOLUTE} %-5p [%c{1}] %m%n log4j.appender.FILE=org.apache.log4j.RollingFileAppender log4j.appender.FILE.Threshold=DEBUG log4j.appender.FILE.lausert=org.apache.log4j.PatternLausert log4j.appender.FILE.lausert.ConversionPattern=%d{ABSOLUTE} %-5p [%c{1}] %m%n Listing 11.2 - Sample of server-log4j.properties file
Chapter 11 – Troubleshooting 201 The server-log4j.properties file can also be edited from the admin console by selecting the Server Logs portlet. With the admin console, you can also filter the server.log entries. In Linux, AIX, or Solaris users can use the tail -f server.log command to display current entries to the server.log file while the server is running. 11.5.3 Client log Messages from Java EE client applications are written to the file /var/log/client.log. Similar to server.log, you can change the file location, name and the log levels by editing the /var/log/clientlog4j.properties. 11.5.4 Deployer log Messages are generated when an application is deployed to a server. These messages are logged to the /var/log/deployer.log file. You can change the file location, name and the log levels in /var/log/deployerlog4j.properties. 11.5.5 Web log HTTP requests to the Web container are logged. The HTTP request information includes the type of request (GET or POST), the time of access, and other related data. You can see the access log files in the /var/catalina/logs folder. The file name has the format: _access_log..txt For example, 0.0.0.0_access_log.2010-06-29.txt, records all the access information on 2010.06.29 from every client. From the admin console you can review and edit the Web server log file and edit its properties by selecting Server Logs -> Web Access Log Viewer. With the admin console, you can use a filter to narrow down log entries. 11.5.6 DB2 database log DB2 database log files include information about the DB2 database server, such as database startup and shutdown information. There are two main logs: • DB2 Administration Notification log • db2diag.log
