This section contains the following statistics:
These statistics can be accessed online using the EXEC CICS® COLLECT STATISTICS TRANCLASS command, and are mapped by the DFHXMCDS DSECT. For programming information about the EXEC CICS COLLECT STATISTICS command, see the CICS System Programming Reference manual.
DFHSTUP name | Field name | Description |
---|---|---|
Tclass Name | XMCTCL | is the 8-character name of the transaction class.
Reset characteristic: not reset
|
Number Trandfs | XMCITD | is the number of installed transaction definitions that
are defined to belong to this transaction class.
Note:
This will
be a reference count from the latest version of the transaction definition
table. This statistic is useful to identify redundant tclasses. Reset characteristic: not reset
|
Max Act | XMCMXT | is the maximum number of transactions in the named transaction
class that may be active concurrently.
Reset characteristic: not reset
|
Purge Thresh | XMCTH | is the queue limit of the purge threshold at which transactions
in the named transaction class is purged instead of being added to the queue
of transactions that are waiting for membership of the transaction class.
Reset characteristic: not reset
|
TOTAL | ||
-Attaches | XMCTAT | is the total number of attach requests made for transactions
in this transaction class.
Reset characteristic: reset to zero
|
-AcptImm | XMCAI | is the number of transactions that did not have to queue
to become active in this transaction class. They are accepted immediately.
Reset characteristic: reset to zero
|
-PrgImm | XMCPI | is the number of transactions that were purged immediately
because the queue reached the purge threshold for this transaction class.
Reset characteristic: reset to zero
|
-Queued | XMCTQ | is the total number of transaction that have queued for
this transaction class.
Reset characteristic: reset to zero
|
NOT IN THE DFHSTUP REPORT | XMCAAQ | is the number of transactions that have become active
in this transaction class but queued first.
Reset characteristic: reset to zero
|
-PrgQ'd | XMCPWQ | is the number of transactions that have been purged whilst
queuing for acceptance into the transaction class. This includes those transactions
purged explicitly through Master Terminal, or implicitly through the purge
threshold of the transaction class being lowered.
Reset characteristic: reset to zero
|
-Q-Time | XMCTQTME | is the total time in STCK units spent waiting by those
transactions that were queued in the transaction class.
Note:
This
time only includes the time spent by those that have finished queuing. In
order to calculate the average queuing time, current queue must be subtracted
from the 'queued' count. Reset characteristic: reset to zero
|
Peak Act | XMCPAT | is the highest number of active transactions reached in
the transaction class.
Reset characteristic: reset to current value
|
Peak Queued | XMCPQT | is the highest number of transactions queued waiting for
admittance to the transaction class.
Reset characteristic: reset to current value
|
Times MaxAct | XMCTAMA | is the number of separate times that the number of active
transactions in the transaction class was equal to the maximum value (XMCMXT).
Also registers times when maxactive setting of the tclass is zero and there
are no active transactions in the tclass.
Reset characteristic: reset to zero or one if transaction class is currently at its maxactive limit.
|
Times PrgThr | XMCTAPT | is the number of separate times that the purge threshold
of the transaction class has been reached (times at purge threshold).
Reset characteristic: reset to zero or one if transaction class is currently at its purge threshold limit.
|
CURRENT | ||
-Act | XMCCAT | is the current number of transactions currently active
in this transaction class.
Reset characteristic: not reset
|
-Queued | XMCCQT | is the number of transactions that are currently queuing
in this transaction class.
Reset characteristic: not reset
|
-Queue Time | XMCCQTME | is the total time in STCK units spent waiting by those
transactions that are currently queuing in this transaction class.
Reset characteristic: not reset
|
Figure 56 illustrates the transaction class statistics.
