ISC/IRC system entry: Summary resource statistics
ISC/IRC system entry summary resource statistics are not available online.
| DFHSTUP name | Description |
|---|---|
| Connection name | is the system entry defined by the CONNECTION definition in the CSD or by autoinstall. |
| Connection netname | is the name by which the remote system is known in the network—that is, its applid. |
| Access Method / Protocol | is the combined communication access method and protocol used for the connection. |
| Average autoinstalled connection time | is the average autoinstalled connection time. This field applies to
autoinstalled connections and is summarized from the unsolicited system entry statistics records
only.
|
| Send session count | is the last value encountered for the SENDCOUNT specified on the CONNECTION definition. This field applies to MRO and LU6.1 connections only. |
| Receive session count | is the last value encountered for the RECEIVECOUNT specified on the CONNECTION definition. This field applies to MRO, LU6.1, and EXCI connections only. |
| Average number of aids in chain | is the average number of automatic initiate descriptors in the AID chain. |
| Average number of generic aids in chain | is the average number of automatic initiate descriptors that were waiting for a session to become available to satisfy an allocate request. |
| Average peak number of aids in chain | is the average of the peak number of automatic initiate descriptors that were present in the AID chain. |
| ATIs satisfied by contention losers | is the total number of ATI requests (queued allocates) that have been satisfied by contention loser sessions (primaries for LU6.1). This is always zero for IRC system entries. |
| ATIs satisfied by contention winners | is the total number of ATI requests (queued allocates) that have been satisfied by contention winner sessions (secondaries for LU6.1). This field is the total ATIs when the system entry is for IRC. |
| Peak contention losers | is the peak number of contention loser sessions (primaries for LU6.1) that were in use at any one time. |
| Peak contention winners | is the peak number of contention winner sessions (secondaries for LU6.1) that
were in use at any one time.
|
| Total bids sent | is the total number of bids that were sent. A bid is sent on an LU6.1 RECEIVE session only. This field is always zero for IRC and APPC system entries. |
| Average bids in progress | is the average number of bids in progress. A bid is sent on an LU6.1 RECEIVE session only. This field is always zero for IRC and APPC system entries. |
| Peak bids in progress | is the peak number of bids that were in progress at any one time. A bid is sent on an LU6.1 RECEIVE session only. This field is always zero for IRC and APPC system entries. |
| Peak outstanding allocates For more information see 1 |
is the peak number of allocation requests that were queued for this system. For APPC this field contains only generic allocate requests. |
| Total number of allocates For more information see 1 |
is the total number of allocate requests against this system. For APPC this field contains only generic allocate requests. |
| Average number of queued allocates For more information see 1 |
is the average number of queued allocate requests against this system. For APPC this field is incremented only for generic allocate requests. |
| Failed link allocates For more information see 1 |
is the total number of allocate requests that failed due to the connection being released, out of service, or with a closed mode group. For APPC this field is incremented only for generic allocate requests. |
| Failed allocates due to sessions in use For more information see 1 |
is the total number of allocate requests that failed due to a session not being currently available for use. These requests get SYSBUSY responses to the allocate. This field is incremented for allocates failing with an AAL1 abend code. For APPC this field is incremented only for generic allocate requests. |
| Maximum queue time (seconds) | is the last non-zero value encountered for the MAXQTIME parameter specified on
the CONNECTION definition. This value represents the maximum time you require to process an allocate
queue on this connection. If the allocate queue would take greater than this time to process the
entire queue would be purged. This value only takes effect if the QUEUELIMIT value has been reached.
|
| Allocate queue limit | is the last non-zero value encountered for the QUEUELIMIT parameter specified on the CONNECTION definition. If this value is reached then allocates are rejected. |
| Number of QUEUELIMIT allocates rejected | is the is the total number of allocates rejected due to the QUEUELIMIT value being reached. |
| Number of MAXQTIME allocate queue purges | is the total number of times an allocate queue has been purged due to the MAXQTIME value. A queue is purged when the total time it would take to process a queue exceeds the MAXQTIME value. |
| Number of MAXQTIME allocates purged | is the total number of allocates purged due to the queue processing time
exceeding the MAXQTIME value. If sessions have not been freed after this mechanism has been invoked then any subsequent allocate requests are purged and included in this statistic as the MAXQTIME purging mechanism is still in operation.
|
| Number of XZIQUE allocates rejected | is the total number of allocates rejected by the XZIQUE exit |
| Number of XZIQUE allocate queue purges | is the total number of allocate queue purges that have occurred at XZIQUE request for this connection. |
| Number of XZIQUE allocates purged | is the total number of allocates purged due to XZIQUE requesting that queues
should be purged for this connection. 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.
|
| File control (FC) function shipping requests | is the total number of file control requests for function shipping. |
| Interval control (IC) function shipping requests | is the total number of interval control requests for function shipping. |
| Program control (PC) function shipping requests | is the total number of program control link requests for function shipping. |
| Transient data (TD) function shipping requests | is the total number of transient data requests for function shipping. |
| Temporary storage (TS) function shipping requests | is the total number of temporary storage requests for function shipping. |
| DL/I function shipping requests | is the total number of DL/I requests for function shipping. |
| Terminal sharing requests | is the total number of transaction routing commands. This number is incremented on both regions when the transaction is routed, and when the terminal I/O request is routed between regions. This field is not supported for LU6.1. |
Note:
- For APPC only, if an allocate request does not specify a mode group (so it is a generic allocate request), CICS® takes the first mode group within the sessions available, and the statistics for these allocates are reported against the system entry and against the mode entry (in the statistic 'Total generic allocates satisfied'). If an allocate specifically requests a mode entry (so it is a specific allocate request), the statistics for these allocates go into that mode entry.
