Open Objects I/O sub-page

The Open Objects I/O sub-page displays a grid that shows a listing of each object on the selected database (selected on the Databases grid) that is either open, or has been open, and related I/O activity.

Objects are only removed from the list if the configured number of "open objects" is exceeded. Then they are aged out to make room for newly opened objects.

The following table defines the columns on the Open Objects I/O for Database grid:
