This attribute has a value equal to the number of backup log files that will be retained for historical analysis. Any integer can be entered depending on the partition size and available disk space of the local system. The default value is 3.
The files only apply to the FILE logging type. When the logging type is set to DB, there are no history files and limit explicitly set by Access Manager to the size of the files.
Entering a value of 0 is interpreted to be the same as a value of 1, meaning that if you specify 0, a history log file will be created.
