IPCONN: Summary resource statistics
A summary listing of resource statistics for each IPCONN. You can use IPCONN statistics to detect problems with IP interconnectivity (IPIC) connections.
Summary resource statistics are not available online.
IPIC is described in Communication between systems.
| DFHSTUP name | Description |
|---|---|
| IPCONN Name | The name of an IPIC connection defined by an IPCONN definition in the CSD, or by autoinstall. |
| Autoinstalled IPCONN Create Date / Time | The date and time when the IPCONN was autoinstalled. The
time shown is local time. If the IPCONN was not autoinstalled, this field is not shown. |
| Autoinstalled IPCONN Delete Date / Time | The date and time when the autoinstalled IPCONN was
deleted. The time shown is local time. If the IPCONN was not autoinstalled, this field is not shown. |
| IPCONN Applid | The APPLID of the remote system, as specified in its system initialization table. |
| IPCONN Network ID | The network ID (that is, the z/OS® Communications Server NETID or, for non-z/OS Communications Server systems, the value of the UOWNETQL system initialization parameter) of the remote system. This ID is used, in combination with the APPLID, to ensure unique naming for connecting systems. The name can be up to 8 characters in length and follows assembler language rules. It must start with an alphabetic character. This attribute is optional. If it is not specified, the z/OS Communications Server NETID (or, for non-z/OS Communications Server systems, the value of the UOWNETQL system initialization parameter) of the CICS® on which the definition is installed is used. |
| TCPIPSERVICE name | The name of the PROTOCOL(IPIC) TCPIPSERVICE definition that defines the attributes of the inbound processing for this connection. |
| IPCONN Port Number | The decimal number of the port that is combined with the HOST value to specify the destination for outbound requests on this connection. |
| IPCONN Host | The host name of the target system for this connection. |
| IPCONN IP Family | The address format of the IP Resolved Address. |
| IPCONN IP Resolved Address | The IPv4 or IPv6 address of the host. |
| Receive Sessions | The defined number of receive sessions. |
| Peak Receive Sessions | The peak number of receive sessions in use for this connection. |
| Total Allocates | The total number of allocate requests for this connection. |
| Peak Allocates Queued | The peak number of allocate requests that have been queued for this connection. |
| Allocates Failed - Link | The number of allocate requests that failed because the connection is released or out-of-service. |
| Allocate queue limit | The value of the QUEUELIMIT parameter specified on the IPCONN definition. This value is the maximum number of allocate requests that CICS is to queue while waiting for free sessions. |
| Maximum queue time (seconds) | The MAXQTIME specified on the IPCONN definition. This value represents the maximum time that queued allocate requests, waiting for free sessions on a connection that appears to be unresponsive, can wait. The maximum queue time is used only if a queue limit is specified for QUEUELIMIT; and the time limit is applied only when the queue length has reached the queue limit value. |
| Number of MAXQTIME allocate queue purges | The total number of times an allocate queue has been purged because of 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 | The total number of allocate requests purged because the queue time exceeds the MAXQTIME value. |
| Number of transactions attached | The total number of transactions attached for this connection. |
| Function Shipped Program requests | The number of program control LINK requests for function shipping on this connection. |
| Bytes Sent by Program requests | The number of bytes sent on LINK requests. |
| Bytes Received by Program requests | The number of bytes received on LINK requests. |
| Function Shipped Interval Control requests | The number of interval control requests for function shipping on this connection. |
| Bytes Sent by Interval Control Requests | The number of bytes sent by interval control requests. |
| Bytes Rcvd by Interval Control Requests | The number of bytes received by interval control requests. |
| Send Sessions | The defined number of send sessions. The actual number of sessions used depends also on the number of receive sessions defined in the partner system. When the connection is established, these values are exchanged and the lower value is used. |
| Peak Send Sessions | The peak number of send sessions in use. |
| Allocates Failed - Other | The number of allocate requests that failed because of other reasons. |
| Number of QUEUELIMIT allocates rejected | The total number of allocate requests rejected because the QUEUELIMIT value is reached. |
| Number of XISQUE allocates rejected | The total number of allocate requests rejected by an XISQUE global user exit program. |
| Number of XISQUE allocate queue purges | The total number of allocate queue purges that have occurred because of an XISQUE request for this connection. |
| Number of XISQUE allocates purged | The total number of allocate requests purged because XISQUE requests that allocate queues are purged (ISR_XISQUE_ALLOC_QPURGES) for this connection. If XISQUE has not subsequently canceled this instruction, any subsequent allocate requests are purged and included in this statistic, because the XISQUE purging mechanism is still in operation. |
| Remote Terminal Starts | The total number of START requests sent from a remote terminal. |
| Transaction Routing requests | The number of transaction routing requests on this connection. |
| Bytes Sent by Transaction Routing requests | The number of bytes sent on transaction routing requests. |
| Bytes Rcvd by Transaction Routing requests | The number of bytes received by transaction routing requests. |
| Function Shipped File Control requests | The number of file control requests for function shipping on this connection. |
| Bytes Sent by File Control Requests | The number of bytes sent by file control requests. |
| Bytes Rcvd by File Control Requests | The number of bytes received by file control requests. |
| Function Shipped Temporary Storage Requests | The number of temporary storage requests for function shipping on this connection. |
| Bytes Sent by Temporary Storage Requests | The number of bytes sent by temporary storage requests. |
| Bytes Rcvd by Temporary Storage Requests | The number of bytes received by temporary storage requests. |
| Function Shipped Transient Data Requests | The number of transient data requests for function shipping on this connection. |
| Bytes Sent by Transient Data Requests | The number of bytes sent by transient data requests. |
| Bytes Rcvd by Transient Data Requests | The number of bytes received by transient data requests. |
| Unsupported Requests | The number of attempts to route requests for unsupported function across this connection. |
