7.12.14 -XX:HitachiExplicitMemoryJavaLogNumberOfFile

Description

-XX:HitachiExplicitMemoryJavaLogNumberOfFile specifies the maximum number of log files to be created and thus prevents the number of created log files from increasing.

If the rotation type is the wraparound method, when the number of files exceeds the maximum number, the log data will again be output to the file that was created first.

If the rotation type is the shift method, when the number of files exceeds the maximum number, the oldest backup file will be deleted.
