Disc File Overview (Alphabetic) (DFOATBL)
Disc File Overview (Alphabetic) (DFOATBL)
This 80-column chart gives an overview of disk file activity. It is ordered by file name
(not qualified by volume or subvolume) to provide quick reference capabilities. This
ordering also tends to group alternate key files close to their primary files and to group
all partitions of a partitioned file together. The chart displays:
•
File name
•
Volume and subvolume
•
File structure (relative, key-sequenced, and so on)
•
Total number of DISCOPENS found for a file
•
Logical I/Os per second
•
System I/Os (driver calls) per second
•
Physical I/Os per second
