The Journal Recovery Count: Making It Count on IBM i5/OS
Note: This is publication is now archived. For reference only.
Inside IBM i5/OS™ is the little known but important journal recovery count function. While this function ships from IBM with a default value, many shops have found it useful to adjust this value. If you set the value too low, you can experience added performance overhead at run time. If you set it too high, you can experience long duration initial program load (IPL) recovery steps. Instead, you must simply select an effective value that works for your shop and your environment.
