Application server log files

When starting and stopping an application server, a number of log files are generated. After starting or stopping an application server check the log files to ensure that both the application server and the application that run inside the application server started or stopped successfully.

The application server log files are in the following directory:

The following log files should be examined after starting or stopping an application server:

stopServer.log

This log file contains messages generated when the application server was stopping. The application server stopped successfully if this log file contains the text, Server servername stop completed, where servername is the name of the application server that was stopped.

SystemErr.log

This log file contains Java exceptions and stack traces. These exceptions are caught by enterprise applications and their associated application servers.

An empty SystemErr.log file does not necessarily indicate success since not all error messages generated by an application are considered to be error messages by the operating system. You must also examine the contents of the SystemOut.log file.

SystemOut.log

This log file contains messages generated when the applications running inside the application server are being started or stopped. This log file will not contain error messages - such messages will appear in the SystemErr.log file. However, this log file will contain error messages that the operating system does not see as error messages.

Both this log file and the SystemErr.log file should be checked after starting an application server to confirm that the applications inside the application server being started have also started successfully.

trace.log

The log file contains the components trace messages while the service is running, if the trace is enabled in the server.

Other log files may appear in the directory but they are not related to the starting and stopping of an application server. Refer to the Working with message logs topic in the WAS documentation for more information about all of the log files appearing in the log files directory.
