I/O Info
% DYNAMIC
The higher the number indicated for % DYNAMIC, the greater the chance that a
dynamic server will be required. It is important to realize that this number does not
indicate:
•
That dynamic servers were in fact started. It does indicate, however, that some
requests were delayed anywhere from not at all to the time specified with the SET
SERVER CREATEDELAY command.
•
The number of dynamic links granted by the PATHMON process. Any request on
the LINK queue can be cancelled by the availability of another existing link.
If the number for %DYNAMIC is large, you might want to increase the number of static
servers.
I/O Info
The I/O INFO section in the statistics display provides information about I/O operations
to and from the server class.
Example 7-3 shows only the I/O INFO section of the sample server statistics. See this
figure as you read this section.
Table 7-2 on page 7-5 shows the server statistics for I/O operations and what they
indicate.
