Table 6 (page 119) shows the statistics for the server-class wait queue and what they indicate. If
these statistics show that requests are queuing, you might consider steps to reduce queuing and
improve response time. Such steps might include reconfiguring your system or modifying the
application.
Table 6 Server Statistics for QUEUE INFO
For Server-Class Wait Queue, Indicates:Statistic
Number of requests for a link that could not be satisfied immediately because of the unavailability
of a link or when the link manager is in the process of requesting a link.
REQ CNT
Percentage of requests for a link (based on REQ CNT) that the ACS subsystem processes queue
when one or more other requests are already queued for the server class.
For example:
% WAIT
A TCP sends 100 requests to a serverclass. It had
to queue 10 of them because no link was
immediately available.
For two of the 10 queued requests, there was
already at least one entry in the queue when the
new entry was to be queued.
In this case, the Queue Info %Wait will be
20%(2/10), not 10% (10/100) or 2% (2/100)."
The maximum number of link requests that were queued in a link manager at any point.MAX WAITS
How many requests were waiting, on average, during the sample period.AVG WAITS
Percentage of requests for a link (based on REQ CNT) that the ACS subsystem processes received
and resulted into a dynamic link.
% DYNAMIC
REQ CNT
REQ CNT indicates the number of requests for a link to a server that could not be satisfied
immediately because of the unavailability of a link or when the link manager is in the process of
requesting a link.
You can compare this number with the REQ CNT number for I/O INFO (see “I/O Info” (page 120)
earlier in this section) to determine what percentage of the transactions requesting a link to a
particular server experienced some delay.
