Screen Description

The Program Load Detail screen displays program loading information for:

• Dialogs
• Maps
• Subschemas
• Tables
• CA ADS applications

Dialogs, maps, subschemas, tables, and CA ADS applications can be loaded from the DDLDCLOD dictionary load area.

The waits indicated on the Program Load Detail screen include I/O waits and BLDL (Building Load Directory List) waits.

The I/O activity counts (reads and writes) exclude I/O against any CDMSnnn files.

What to look for

• Look for a high number of load waits, which indicates I/O activity against load libraries and load areas.
• Look for db-key waits.
• Look at the buffer utilization statistics. Buffer Hits indicates the number of times a requested database page was already in the buffer, saving the system from performing an I/O. Buffer Waits indicates when the system had to wait for an available page in the buffer. The Buffer Detail screen provides more statistics about buffer use.
