Setting CICS VR server address space scavenger parameters

You can control the Inventory Scavenger and the History Scavenger by specifying the parameter values for the Run control time interval and the Run control start time using the CICS® VR server scavenger settings window. The specified parameter values are used to control the scavenger runs for the next time the CICS VR server address space is started.

To set the CICS VR server address space scavenger parameters:

  1. Select option 8, CICS VR Settings, from the CICS VR main menu window to open the CICS VR settings menu window.
  2. Select option 4 from the CICS VR settings menu window to open the CICS VR server scavenger settings window.
  3. Set the time interval and the start time for the Inventory Scavenger and the History Scavenger using this window:

The CICS VR server address space schedules the scavenger runs starting with start time, if the start time is not a blank character string and it is greater than the current time when the CICS VR server address space is started. The scavenger then runs periodically once in each time interval. Otherwise it starts with the next time interval after the CICS VR server address space is started and then again periodically once in each time interval.
Inventory scavenger
The installation default settings for the time interval parameter and the start time parameter respectively is a value of 24 and a blank character string. The default setting means that the inventory scavenger runs once a day starting on the next day after the CICS VR server address space is started. A value of 0 for time interval means that the CICS VR server will not schedule any runs of the inventory scavenger.
History scavenger
The installation default settings for the time interval parameter and the start time parameter respectively is a value of 1 and a blank character string. The default setting means that the history scavenger runs once an hour starting on the next hour after the CICS VR server address space is started.
