I have now tried various combinations of RollingFile and
RollingRandomAccessFile and their settings, but when used from weblogic 12C
with jdk1.8.0_74 I can simply not find a way to make log4j clear the file
after rolling, except if append="false" is added (and everything works fine
when the same configuration is used for logging in eclipse).
Among other things I also tried to remove the Policies tag below so that
SizeBasedTriggerPolicy was not enclosed by a Policies tag. That actually made
things a little worse, and in addition to not clearing the file, when rolling,
there were only made one rolling file with the name .1 instead of the 4 that
was specified.
I think I will end up skipping log4j as I can't skip weblogic :(

Subject: RollingFile does not reset file when rolling
Hi
I use log4j 2.5 on weblogic 12C (By adding the argument
-Dlog4j.Configuration=log4j2.xml) with this configurationfile:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN" monitorInterval="320">
<Appenders>
<RollingFile name="com.logica.poltacho.soap.file.appender"
fileName="D:/oracle/config/domains/poltacho3/servers/server1/logs/poltacho-soap.log"
filePattern="D:/oracle/config/domains/poltacho3/servers/server1/logs/poltacho-soap-%i.log">
<PatternLayout>
<Pattern>%d{ISO8601} %-5p %c{1} transId:
%X{transactionId} %m%n</Pattern>
</PatternLayout>
<Policies>
<SizeBasedTriggeringPolicy size="1 MB" />
</Policies>
<DefaultRolloverStrategy max="4" />
</RollingFile>
</Appenders>
<Loggers>
<Logger name="com.logica.poltacho.ws.SoapHandler" level="info"
additivity="false">
<AppenderRef ref="com.logica.poltacho.soap.file.appender" />
</Logger>
</Loggers>
</Configuration>
The file role when increased with about 1 MB but it is not reset! The result is
that both the logfile and new rolled files keep growing in size like this:
poltacho-soap.log 3>MB
poltacho-soap-3.log 3MB
poltacho-soap-2.log 2MB
poltacho-soap-1.log 1MB
If I add append="false" everything works fine and I get the expected result:
poltacho-soap.log 1<MB
poltacho-soap-3.log 1MB
poltacho-soap-2.log 1MB
poltacho-soap-1.log 1MB
It is just that I don't want any existing logfile to be cleared when
application startup.
If I use the same log4j configuration from eclipse in unittests, everything
works fine also without append="false".
Have you seen this before and can you give me a hint for a solution?
