    RFAJ does not provide the parameter to set the maximum of log file. However, you can split the large log file manually into smaller ones before open/analysis it.

    RFA Java uses the standard J2SE Logging API

    You can specify the patterns as required with the logFileName parameter as part of your connection configuration. See the RFAJ_ConfigLoggingGuide.pdf for details of this parameter and refer to J2SE java.util.logging documentation for the filename patterns to use etc.

    Thanks. I would like RFA Java rotate to a new log file when the log file's size reaches to the maximum.
    Does RFA Java provide the configuration parameter to set the maximum size before it rotates to a new file? I would like this parameter because my log file can be very large e.g.3-4 GB and I cannot open it.

    @SusanGenoray.

    This is really a Java question, rather than a RFA question. As stated in the documentation the RFA Java internally uses the standard JDK FileHandler. As you can see this Handler actually has build-in support for rotation-by-size ... which is what you are asking for.

    So - without actually having tried it - I guess you can solve it by supplying a logging.properties file to your application. Something like -Djava.util.logging.config.file=mycustomlogging.properties on your command line.

    Then in the file mycustomlogging.properties you would have something like:

    # Configure the FileHandler 
    java.util.logging.FileHandler.limit =1024000 

    # Side note: 
    # There's no point in setting the 'java.util.logging.FileHandler.pattern'
    # property here as it will always be overriden by the 'logFileName'
    # parameter from the RFA config.

    I hope that helps.
