How can I determine if I sized my Interval Database correctly?
From the BrightStor CA-ASTEX ISPF main menu, select option D1. From the Select Input menu, choose Previous Interval, specify your Interval Database name in the File field, and leave the Date and Time fields blank. You will be presented with a list of intervals available in your IDB and a Yes/No indicator if detail data is available in each interval. If the list does not contain the number of days you wanted, you can increase the size of your IDB. Note: the IDB may not exceed 2,910 cylinders.
