How to set log4j with unlimited max file size?

I didn't get a definitive answer to this question by Google'ing, so I pose it to the groupthink masterminds and to ensure that a quality answer can be Google-able in the future.

Using log4j RollingFileAppender, I can set the maximum size I want the file to reach before rolling over on itself, like so:

RollingFileAppender rfa = new RollingFileAppender();
rfa.setMaximumFileSize(500000000); // S开发者_Go百科ets the max file size to 500MB

Now, what if I don't ever want this file to be rolled over? How do I set the RollingFileAppender maximum file size to unlimited?

RollingFileAppender extends FileAppender to backup the log files when they reach a certain size.

If you don't want to roll it over, then simply use FileAppender.

Just use Long.MAX_VALUE. Then you're already on a technical limit.

Just use a FileAppender.

talking peanuts:

make sure your filesystem does support the filesize you want to achive. technically it will never be an unlimited filesize due to filesystem restrictions.
