ZPWY-MAP-STATS-TCP1
ZCPMEMMAN 
reports statistics on checkpoint requests that must be handled as a memory-
management request (that is, checkpoints written directly to disk). 
ZCPEMEMMAN contains the following subfields:
ZREQCNT 
is the number of requests for TCP resources.
ZWAIT 
is the percentage of requests that were queued because the resource was 
in use.
ZMAXWAITS 
is the count of the greatest number of queued requests encountered at the 
time a new request was queued.
ZAGGREGATEWAITS 
is the total queued requests encountered at the time a new request is 
queued. To find the average number of queued requests encountered, 
divide ZAGGREGATEWAITS by ZREQCNT.
ZIOCOMP 
identifies the number of I/O operations waiting to be completed. ZIOCOMP has the 
following subfields:
ZWAIT 
is the number of the completed I/Os that required the TCP to wait.
ZNOWAIT 
is the number of the completed I/Os that did not require the TCP to wait for 
completion. To find the percentage of NOWAIT I/O, divide ZWAIT by (ZWAIT + 
ZNOWAIT). To find the percentage of waited I/O, divide ZNOWAIT by (ZWAIT 
+ ZNOWAIT).
