[logging] Problems to configure logging rotation.

Question

Hi,
I have an application .ear deployed in weblogic v10.3.1.0
This application use java.util.logging to write a log file.
      fh = new FileHandler(logFileName,0,1,true);
      fh.setFormatter(new XMLFormatter());
      logger.addHandler(fh);
FileHandler(String pattern, int limit, int count, boolean append)
pattern - the pattern for naming the output file
limit - the maximum number of bytes to write to any one file. If this is zero, then there is no limit. (Defaults to no limit).
count - the number of files to use
append - specifies append mode
http://www.javadocexamples.com/java/util/logging/java.util.logging.FileHandler.html
logFileName is dynamic with date formated like this yyyMMdd + ApplicationName + ".log"
This file is created but I have also yyyyMMddSEC.log.1, yyyyMMddSEC.log.2, yyyyMMddSEC.log.3,...
I DON'T WANT THESE FILES_, that's why I put limit to 0, count to 1 and append to true.
This code works without jdev/weblogic but has not effect in weblogic.
Q1. Why?
So I go to Weblogic console: Domain Structure-> DefaultDomain->Logging
Log file name: logs/DefaultDomain.log
Rotation type: None
NONE
Messages accumulate in a single file.
You must erase the contents of the file when the size is too large.
Note that WebLogic Server sets a threshold size limit of 500 MB before it forces a hard rotation to prevent excessive log file growth.
But it doesn't work, Weblogic continue to create log files like this *<filename>.log.<n>*
Q2. Why?
I have also created weblogic.xml in ViewControler/WEB-INF
thanks to this documentation:
http://download.oracle.com/docs/cd/E13222_01/wls/docs103/webapp/weblogic_xml.html#wp1063199
but it doesn't work...again.
Q3. Why?
Q4. If I want applications manage themselves their log, how to deactivate the logging handler in weblogic (LogFileMBean?)
Thanks for your help.

Answer 1

You may want to ask in the WebLogic Server - Diagnostics / WLDF / SNMP forum. They own logging.
