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).
