ISC mode entry: Resource statistics
These statistics cannot be retrieved using the EXEC CICS EXTRACT STATISTICS command. They are only produced for offline processing (written to SMF).
These statistics are mapped by the DFHA20DS DSECT. This DSECT is also used to map the mode entry totals records.
| DFHSTUP name | Field name | Description |
|---|---|---|
| NOT IN THE DFHSTUP REPORT | A20SYSN | is the name of the APPC connection/system that
owns this mode entry. It corresponds to the system entry, defined
by a CONNECTION definition in the CSD or by autoinstall. Reset characteristic: not reset
|
| Mode name | A20MODE | is the mode group name related to the the intersystem connection name (A20SYSN).
This corresponds to modename in the sessions definition. Reset characteristic: not reset
|
| ATIs satisfied by contention losers | A20ES1 | is the number of ATI requests (queued allocates)
that have been satisfied by “contention loser” sessions
belonging to this mode group. Reset characteristic: reset to zero
|
| ATIs satisfied by contention winners | A20ES2 | is the number of ATI requests (queued allocates)
that have been satisfied by “contention winner” sessions
belonging to this mode group. Reset characteristic: reset to zero
|
| Current contention losers in use | A20E1RY | is the number of contention loser sessions currently
in use. Reset characteristic: not reset
|
| Peak contention losers | A20E1HWM | is the peak number of “contention loser”
sessions belonging to this mode group that were in use at any one
time. There can be sessions not defined (by the MAXIMUM parameter)
as “contention winners” or “contention losers”,
and their states are dynamically decided at bind time. Reset characteristic: reset to current value
|
| Current contention winners in use | A20E2RY | is the number of contention winner sessions currently
in use. Reset characteristic: not reset
|
| Peak contention winners | A20E2HWM | is the peak number of “contention winner”
sessions belonging to this mode group that were in use at any one
time. There can be sessions not defined (by the MAXIMUM parameter)
as “contention winners” or “contention losers”,
and their states are dynamically decided at bind time. Reset characteristic: reset to current value
|
| Total bids sent | A20ESBID | is the number of bids that were sent on the sessions
defined to this mode group. A bid is sent on an APPC “contention
loser” session when there are no “contention winner”
sessions available to allocate. Reset characteristic: reset to zero
|
| Current bids in progress | A20EBID | is the number of bids that are in progress on
the sessions defined to this mode group. A bid is sent on an APPC
“contention loser” session when there are no “contention
winner” sessions available to allocate. Reset characteristic: not reset
|
| Peak bids in progress | A20EBHWM | is the peak number of bids that were in progress
at any one time, on the sessions defined to this mode group. A bid
is sent on an APPC “contention loser” session when there
are no “contention winner” sessions available to allocate.
Reset characteristic: reset to current value
|
| Peak outstanding allocates For more information see 1 |
A20ESTAM | is the peak number of allocation requests that
were queued for this mode group. Reset characteristic: reset to current value
|
| Total specific allocate requests For more information see 1 |
A20ESTAS | is the number of specific allocate requests against
this mode group. Reset characteristic: reset to zero
|
| Total specific allocates satisfied For more information see 1 |
A20ESTAP | is the number of specific allocates satisfied
by this mode group. Reset characteristic: reset to zero
|
| Total generic allocates satisfied | A20ESTAG | is the number of generic allocates satisfied from
this mode group. The allocates are made for APPC without the mode
group being specified. Reset characteristic: reset to zero
|
| Queued allocates For more information see 1 |
A20ESTAQ | is the current number of queued specific allocate
requests against this mode group. An allocate is queued due to a
session in this mode group not being available at this moment. This
includes waiting for a bind, a bid, or all sessions are currently
in use. Reset characteristic: not reset
|
| Failed link allocates For more information see 1 |
A20ESTAF | is the number of specific allocate requests that
failed due to the connection being released, out of service, or with
a closed mode group. Reset characteristic: reset to zero
|
| Failed allocates due to sessions in use For more information see 1 |
A20ESTAO | is the number of specific allocate requests that
failed due to a session not being currently available for use in this
mode group. These requests get SYSBUSY responses to the allocate.
This field is incremented for allocates failing with an AAL1 abend
code. Reset characteristic: reset to zero
|
| Number of XZIQUE allocate queue purges | A20EQPCT | is the total number of allocate queue purges that
have occurred at XZIQUE request for this mode entry. Reset characteristic: reset to zero
|
| Number of XZIQUE allocates purged | A20EZQPC | is the total number of allocates purged due to
XZIQUE requesting that queues should be purged (A20EQPCT) for this
mode entry. If XZIQUE has not overridden this mechanism (by response) then any subsequent allocate requests are purged and included in this statistic as the XZIQUE purging mechanism is still in operation. Reset characteristic: reset to zero
|
| Maximum session count | A20ELMAX | is the maximum number of sessions that the definition
of the session group permits. Reset characteristic: not reset
|
| Current maximum session count | A20EMAXS | is the current number of sessions in the group
(the number “bound”). Reset characteristic: not reset
|
| Maximum contention winners acceptable | A20EMCON | is the maximum number of sessions that the definition
of the session group permits to be contention winners. Reset characteristic: not reset
|
| Current CNOS contention losers | A20ECONL | is the current number of CNOS negotiated contention
loser sessions. Reset characteristic: not reset
|
| Current CNOS contention winners | A20ECONW | is the current number of CNOS negotiated contention
winner sessions. Reset characteristic: not reset
|
- This field is incremented when an allocate is issued against a specific mode group. If a generic allocate request is made, the equivalent system entry statistics only are incremented.
