requests for REPLY.
I/O CNT
Statistics are not provided for REPLY statements because there are no explicit
requests for REPLY.
Server Statistics Collected Only By the TCP
Server statistics show the amount of link manager resources used to communicate
with a server class. Only TCPs collect server statistics that provide information about:
•
Response time (RESPONSE TIME INFO)
•
Frequency distribution (optional)
These statistics are collected only if your environment includes the Pathway/iTS
product.
Response Time Info
The RESPONSE TIME INFO section of the statistics display provides information
about the completion of SCREEN COBOL SEND statements.
The measurements are gathered by the TCP for the servers with which it has links. As
operations proceed, the TCP captures each measurement by starting an internal clock
the moment after it issues a SEND statement and stopping the clock the moment after
it receives a reply from the server process. The captured measurements represent
server response time.
Example 7-4
shows only the RESPONSE TIME INFO section of the sample server
statistics. See this example as you read this section.
