The enqueue domain collects global statistics for enqueue requests.
This section contains the following statistics:
These statistics fields contain the global data collected by the enqueue domain for enqueue requests.
These statistics can be accessed online using the EXEC CICS® COLLECT STATISTICS ENQUEUE command, and are mapped by the DFHNQGDS DSECT. For programming information about the EXEC CICS COLLECT STATISTICS command, see the CICS System Programming Reference manual.
DFHSTUP name | Field name | Description |
---|---|---|
NOT IN THE DFHSTUP REPORT | NQGNPOOL | is the number of enqueue pools.
Reset characteristic: not reset
|
ENQ Poolname | NQGPOOL | is the enqueue pool id.
Reset characteristic: not reset
|
ENQs Issued | NQGTNQSI | is the total number of enqueue requests issued.
Reset characteristic: reset to zero
|
ENQs Waited | NQGTNQSW | is the total number of enqueue requests that had waited
due to the enqueues being held. This is a subset of NQGTNQSI.
Note that this value does not include the enqueue requests currently waiting (see NQGCNQSW). Reset characteristic: reset to zero

Enqueue Waiting time | NQGTNQWT | is the total waiting time for the enqueue requests that
waited (NQGTNQSW).
Note that this value does not include the time for the enqueue requests currently waiting (see NQGCNQWT). Reset characteristic: reset to zero
|
NOT IN THE DFHSTUP REPORT | NQGCNQSW | is the current number of enqueue requests waiting.
Reset characteristic: not reset
|
NOT IN THE DFHSTUP REPORT | NQGCNQWT | is the total waiting time for the enqueue requests that
are currently waiting due to the enqueue being held by another transaction.
Reset characteristic: not reset
|
Sysplex Waited | NQGGNQSW | is the total number of sysplex enqueue requests that had
waited due to the enqueues being held.
Reset characteristic: reset to zero
|
Sysplex Waiting time | NQGGNQWT | is the total waiting time for the sysplex enqueue requests
that waited (NQGGNQSW).
Reset characteristic: reset to zero
|
NOT IN THE DFHSTUP REPORT | NQGSNQSW | is the current number of sysplex enqueues waiting.
Reset characteristic: not reset
|
NOT IN THE DFHSTUP REPORT | NQGSNQWT | is the total waiting time for the sysplex enqueues that
are currently waiting (NQGSNQSW).
Reset characteristic: not reset
|
Enqueues Retained | NQGTNQSR | is the total number of enqueues that were retained due
to the owning UOW being shunted.
Note that this value does not include the enqueues that are currently retained (see NQGCNQSR). For more information about shunted UOWs see Recovery manager statistics. Reset characteristic: reset to zero
|
Enqueue Retention | NQGTNQRT | is the total retention time for the enqueues that were
retained due to the owning UOW being shunted.
Note that this value does not include the enqueue retention time for those currently retained (see NQGCNQRT). For more information about shunted UOWs see Recovery manager statistics. Reset characteristic: reset to zero
|
NOT IN THE DFHSTUP REPORT | NQGCNQSR | is the current number of enqueues retained.
Reset characteristic: not reset
|
NOT IN THE DFHSTUP REPORT | NQGCNQRT | is the current enqueue retention time.
Reset characteristic: not reset
|
Immediate-rejection | ||
-Enqbusy | NQGTIRJB | is the total number of enqueue requests that were immediately
rejected due to the enqueue being busy (ENQBUSY response). This value is a
subset of the total number of enqueue requests (NQGTNQSI).
Reset characteristic: reset to zero
|
-Retained | NQGTIRJR | is the total number of enqueue requests that were immediately
rejected due to the enqueue being in a retained state. This value is a subset
of the total number of enqueue requests (NQGTNQSI).
Reset characteristic: reset to zero
|
Waiting rejection | ||
-Retained | NQGTWRJR | is the total number of waiting enqueue requests that were
rejected due to the required enqueue moving into a retained state. This value
is a subset of the number of enqueue requests that waited (NQGTNQSW).
Reset characteristic: reset to zero
|
-Operator | NQGTWPOP | is the total number of waiting enqueue requests that were
rejected due to the operator purging the waiting transaction. This value is
a subset of the number of enqueue requests that waited (NQGTNQSW).
Reset characteristic: reset to zero
|
-Timeout | NQGTWPTO | is the total number of waiting enqueue requests that were
rejected due to the timeout value (DTIMEOUT) being exceeded. This value is
a subset of the number of enqueue requests that waited (NQGTNQSW).
Reset characteristic: reset to zero
