RE: RollingFileAppender not working on AIX

[Jitendra Kharche]

 
Thanks Arnold.

I am using both log4cxx (v0.9.7) and log4j (v1.2.8). RollingFileAppender
works fine with log4j but not with log4cxx (with the similar
configuration).

I will try with changes you suggested. But I am not able to find any
package named 'org.apache.log4j.rolling' both in the log4j jar as well
as the c++ distribution. So I am wondering how will it work.

Please help.

I'm pretty sure that configuration file would not work with log4j 1.3
either.  org.apache.log4j.rolling.RollingFileAppender requires a nested
triggeringPolicy (which determines when a roll occurs) and a nested
rollingPolicy (which determines how files are named), though they can be
both provided by a single class that implements both interfaces.  From
your configuration file, it appears that you want some combination of
date and size based rolling, though neither log4j or log4cxx current
provide that.  If you were trying to specify a date based rolling,
neither log4j or log4cxx support a MaxBackupIndex as it is very
difficult to determine what files should be deleted for an arbitrary
date pattern.

Here is an example of a o.a.l.RFA configured with time-based rolling
policy (from the unit tests)

   <appender name="ROLL"  
class="org.apache.log4j.rolling.RollingFileAppender">
     <rollingPolicy
class="org.apache.log4j.rolling.TimeBasedRollingPolicy">
       <param name="fileNamePattern" value="output/test1-%d{yyyy-MM-
dd_HH_mm_ss}"/>
     </rollingPolicy>

     <layout class="org.apache.log4j.PatternLayout">
       <param name="ConversionPattern" value="%c{1} - %m%n"/>
     </layout>  
   </appender>

and a sized based policy (from scratch so it might be a little buggy)

  <appender name="ROLL"  
class="org.apache.log4j.rolling.RollingFileAppender">
     <triggeringPolicy
class="org.apache.log4j.rolling.SizeBasedTriggeringPolicy">
                <param name="MaxFileSize" value="10KB" />
    </triggeringPolicy>
   <rollingPolicy
class="org.apache.log4j.rolling.FixedWindowRollingPolicy">
                <param name="FileNamePattern" value="/tmp/log.txt.%i"/>
                 <param name="MaxIndex" value="10"/>
   </rollingPolicy>

     <layout class="org.apache.log4j.PatternLayout">
       <param name="ConversionPattern" value="%c{1} - %m%n"/>
     </layout>  
   </appender>
