Logging by EAServer classes and Java clients is written to a log file whose name is determined by the system property djc.logFile. If you do not explicitly set this property, the default file name is default.log, which is created in the server’s logs subdirectory.
Table 3-4 defines logging properties that you can set either on the command line, or in either local-setenv.bat (Windows) or local-setenv.sh (UNIX).
You can also enable the logging and tracing properties defined
on the server’s Log/Trace tab, by prepending “djc.” to
the configuration property name, and setting the value to true.
For example, to enable EJB tracing, set djc.ejbTrace=true;
to echo logging to the console, set djc.echoLog=true.
Property |
Description |
|---|---|
djc.logFile |
The name and path of the log file. |
djc.logFileReUse |
Specify whether to overwrite the contents of the log file when it reaches its maximum size; true or false. |
djc.logFileMaxSize |
The maximum file size. Specify one of:
|
djc.logFileRotation |
Specify whether to create a new log file when the existing log file reaches its maximum size; true or false. If set to true, log files are named sequentially; for example, mylog.log.001, mylog.log.002, and so on. |
djc.logFileArchive |
Specify whether to archive the log file; true or false. |
djc.logFileArchiveName |
To archive the log file, specify the name of the archive file. The value of djc.logFileArchive must be true. |
djc.logFileArchiveCompress |
Specify whether to compress log file archives; true or false. If set to true, the log file archive is compressed to a file named ${djc.logFileArchiveName}.zip |
Setting logging options on the command line
To set logging options on the command line, use:
-Ddjc.logFile=/myserver/myserver.log -Ddjc.logFileMaxSize=5m -Ddjc.logFileRotation=true
When you run a Java client, you can specify logging options on the command line; for example:
%JAVA_HOME%\bin\java -Ddjc.rmiTrace=true -Ddjc.logFile=%DJC_HOME%\logs\rmiClientTrace.log myClient
Setting logging options in local-setenv.bat or local-setenv.sh
To specify log options in local-setenv.bat or local-setenv.sh, so they are set every time you start the server, use:
set DJC_JVM_ARGS=%DJC_JVM_ARGS% -Ddjc.logFile=/myserver/myserver.log -Ddjc.logFileMaxSize=5m -Ddjc.logFileRotation=true
