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.
