ISC mode entry: Summary resource statistics
A summary listing of ISC mode entry resource statistics is available. Summary resource statistics are not available online. These statistics are collected only if you have an APPC connection defined in your CICS® region, and they are then produced for each mode group defined in that connection.
| DFHSTUP name | Description |
|---|---|
| Connection name | The name of the APPC connection/system that owns this mode entry. |
| Mode name | The mode group name related to the intersystem connection name in the previous row. It corresponds to the modename in the sessions definition. |
| ATIs satisfied by contention losers | The total number of ATI requests (queued allocates) that have been satisfied by “contention loser” sessions belonging to this mode group. |
| ATIs satisfied by contention winners | The total number of ATI requests (queued allocates) that have been satisfied by “contention winner” sessions belonging to this mode group. |
| Peak contention losers | 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 as “contention winners” or “contention losers”, and their states are dynamically decided at bind time. |
| Peak contention winners | 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 as “contention winners” or “contention losers”, and their states are dynamically decided at bind time. |
| Total bids sent | The total 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. |
| Average bids in progress | The average number of bids in progress. |
| Peak bids in progress | 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. |
| Peak outstanding allocates | The peak number of allocation requests that were queued for this mode group.
For more information, see note 1. |
| Total specific allocate requests | The total number of specific allocate requests against this mode group. For more information, see note 1. |
| Total specific allocates satisfied | The total number of specific allocates satisfied by this mode group. For more information, see note 1. |
| Total generic allocates satisfied | The total number of generic allocates satisfied from this mode group. The allocates are made for APPC without the mode group being specified. |
| Average number of queued allocates | The average 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. For more information, see note 1. |
| Failed link allocates | The total number of specific allocate requests that failed due to the connection
being released, out of service, or with a closed mode group. For more information, see note 1. |
| Failed allocates due to sessions in use | The total 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. For more information, see note 1. |
| Number of XZIQUE allocate queue purges | The total number of allocate queue purges that have occurred at XZIQUE request for this mode entry. |
| Number of XZIQUE allocates purged | The total number of allocates purged due to XZIQUE requesting that queues should
be purged (Number of XZIQUE allocate queue purges) 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. |
Note:
- The next three fields only contain allocates against specific mode groups. Generic allocate requests are contained in the equivalent system entry statistics.
