TS/MP 2.5 System Management Manual

In a well-tuned system (with no dynamic servers), the only delay occurs at startup time, when initial
links are granted to servers in the server class. If statistics are reset after startup, then the server
queue counts must be 0. If the server queue counts are not 0, then you must increase the number
of static servers.
% DYNAMIC
The higher the number indicated for % DYNAMIC, then 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. However, it does indicate, 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 22 (page 120) shows only the I/O INFO section of the sample server statistics. See this
figure as you read this section.
