n
The number of seconds between mandatory extent switches by AI File Management. Omit -aiarcinterval for on-demand mode.
Use After-image File Management Archive Interval (-aiarcinterval) to specify timed or on-demand mode for the operation of AI File Management. If you specify timed mode, n sets the elapsed time in seconds between forced AI extent switches. The minimum time is two minutes, the maximum is 24 hours. If you omit this parameter to indicate on-demand mode, there are no mandatory extent switches other than when an extent is full. You can modify the interval on a running system with RFUTIL. Regardless of the mode, AI File Management archives full AI extents every five seconds. This parameter is useful only when running the AI File Management utility.
