3307ee06_Chapter_4__Appenders__Property_Name
[Type] boolean [Description] FixedWindowRollingPolicy is not supported in prudent mode. RollingFileAppender supports the prudent mode in conjunction with TimeBasedRollingPolicy albeit with two restrictions. In prudent mode, file compression is not supported nor allowed. (We can't have one JVM writing to a file while another JVM is compressing it.) The file property of FileAppender cannot be set and must be left blank. Indeed, most operating systems do not allow renaming of a file while another process has it opened. See also properties for FileAppender. [Property Name]
