Use After-image File Management Archive Interval (-aiarcinterval) to specify the extent switch interval for timed-mode archiving. For on-demand archiving, do not specify this parameter.

n
The number of seconds between mandatory extent switches by the AI File Management utility.

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.

In both timed and on-demand modes, the AI File Management utility archives full AI extents every 5 seconds.

Note: This parameter is useful only when running the AI File Management utility.

After-image File Management Archive Interval (-aiarcinterval) may be modified while your database is online using PROMON or through the _DbParams VST.

You can use this parameter to support continuous operation of the database. For more information, see Change database parameters while the database is running.
