Cross-System Coupling Facility Report
The Cross-System Coupling Facility Report shows the activity of the Cross-System Coupling Facility (XCF). The information can be presented in a summarized format for the system and individually by the member.
The Cross-System Coupling Facility Report is produced by using the XCF Analyzer control statement. The data for this report is obtained by using the XCFDATA Extractor control statement.
There are three sections to this report:
- System Summary
- Path Utilization Section
- Detail Report
The following figure shows an example of the Cross-System Coupling Facility Report.

System Summary section field descriptions
The table below describes each field in the System Summary section of the Cross-System Coupling Facility Report.
Field | Description | |
|---|---|---|
FROM SYSTEM | system from which the message originated (for internal messages this is the same as the TO SYSTEM) | |
TO SYSTEM | system to which the message is sent (for internal messages this is the same as the FROM SYSTEM) | |
TRANSPORT CLASS | transport class name as defined to XCF An asterisk is printed to the left of the Transport Class value if, at any time during the reporting interval, the transport class was inactive or its counts were reset by the XCF. | |
BUFFER LENGTH | size of the message buffer | |
REQUESTS SATISFIED | number of messages successfully sent where a TRANSPORT CLASS received a TO SYSTEM message that originated from its own FROM SYSTEM | |
BUFFER EFFICIENCY PERCENTAGES | information under this section head is related to buffer efficiency: | |
DEGRADED | percentage of MSG GT BUFFER that suffered degradation due to overhead incurred by XCF in finding a suitably large buffer | |
MSG GT BUFFER | percentage of the messages satisfied that required a larger buffer length than defined for the Transport Class | |
MSG LT BUFFER | percentage of the messages satisfied that required less buffer length than defined for the Transport Class | |
MSG = BUFFER | percentage of the messages satisfied that required the same buffer length as defined for the Transport Class | |
MESSAGES MIGRATED TO ALT PATH | number of messages migrated to an alternate path because the designated primary path was not available | |
MESSAGES REJECTED | number of messages rejected due to an XCF failure to obtain sufficient buffer space | |
Path Utilization Section field descriptions
The table below describes each field in the Path Utilization Section of the Cross-System Coupling Facility Report.
Field | Description | |
|---|---|---|
FROM SYSTEM | system from which the message originated (for internal messages this is the same as the TO SYSTEM) | |
TO SYSTEM | system to which the message is sent (for internal messages this is the same as the FROM SYSTEM) | |
TRANSPORT CLASS | transport class name as defined to XCF Information not available for an inbound path is marked with <INBOUND> in that column for all inbound paths. | |
FROM-TO DEVICE/STRUCTURE | address of the CTC devices from which and to which messages are sent along this path, or the name of the coupling facility structure used to send messages | |
REQUESTS SATISFIED | number of messages successfully sent on this path | |
AVERAGE QUEUE LEN | average number of messages that had to wait to be sent along this path | |
AVERAGE TRANSFER TIME | average I/O time, in milliseconds, for the most recently received signals (within the last 35 minutes) on inbound paths | |
RETRY | information under this section is related to the number of times that XCF had to retry to send messages: | |
LIMIT | maximum number of times XCF can retry to send a message | |
COUNT | number of times XCF had to retry to send messages | |
PERFORMANCE PERCENTAGES | information under this section is related to XCF message sending performance: | |
REFUSED | percentage of all message requests that were refused because the maximum message limit had been reached (inbound only) | |
APPEND. | percentage of all message requests that were appended to a message or messages already in the process of being sent over the path (outbound only) | |
IMMED. | percentage of all message requests that were sent over a path that was suspended (not busy) at the inception of the path request (outbound only) | |
MEMBER STATUS | status of the member during the recording interval Valid values for this field can be Active, Partly Activated, De-activated, or Counts Reset. | |
Detail Report section field descriptions
The table below describes each field in the Detail Report section of the Cross-System Coupling Facility Report.
Field | Description | |
|---|---|---|
SYSTEM | system on which this path, group, and member is defined | |
GROUP | group to which the member is assigned | |
MEMBER | member name | |
MESSAGES RECEIVED | information under this section header is related to the number of XCF messages that were received by members: | |
COUNT | number of messages received for this member | |
PERCENT OF TOTAL | percentage of all messages received that were for this member | |
MESSAGES SENT | information under this section header is related to the number of XCF messages that were sent for members: | |
COUNT | number of messages sent for this member | |
PERCENT OF TOTAL | percentage of all messages sent that were for this member | |
MEMBER STATUS | status of the member during the recording interval Members can be Active, Partially Activated, Re-activated, or De-activated. | |
