DFHSTUP reports
This section lists the CICS® statistics
and associated DFHSTUP reports, grouped by the type of statistics,
and provides more information about interpreting the statistics.
Asynchronous services statistics
The asynchronous services domain collects global statistics on the use and activity of the CICS asynchronous API.
Atom feed statistics
The W2 domain collects statistics for ATOMSERVICE resource definitions, which define Atom feeds.
Autoinstall statistics
This is the DFHSTUP listing for terminals that are connected, while the system is running, by means of the autoinstall facility.
BUNDLE statistics
The resource life-cycle (RL) domain collects statistics for BUNDLE resource definitions, which define application bundles in a CICS region.
CICS Db2 statistics
Statistics are provided for the Db2® connection and each installed DB2ENTRY.
Coupling facility data tables server statistics
Coupling facility data tables server statistics are provided by the AXM page pool management routines for the pools AXMPGANY and AXMPGLOW.
DBCTL session termination statistics
DBCTL statistics are of the unsolicited type only. They appear on a separate report to the other types of CICS statistics.
Dispatcher domain statistics
Document template statistics
Document templates are used in CICS web support to produce the body of HTTP messages. They can be specified in a URIMAP definition to provide a static response to a web client request, or they can be used by an application program to make an HTTP request or response, or for other uses.
Dump domain statistics
Both transaction and system dumps are very expensive and should be thoroughly investigated and eliminated.
Enqueue domain statistics
The enqueue domain collects global statistics for enqueue requests.
Event processing statistics
Front end programming interface (FEPI) statistics
FEPI statistics contain data about the use of each FEPI connection, each FEPI pool, and a target in any pool.
File control statistics
There are four sections in the DFHSTUP report for file statistics, dealing with resource information, requests information, data table requests information, and performance information.
ISC/IRC system and mode entry statistics
The ISC/IRC system and mode entry statistics area of the DFHSTUP listing is for a CICS system using intersystem communication. This provides summary statistics for the CICS intercommunication facility.
ISC/IRC attach time entry statistics
IPCONN statistics
Journalname statistics
CICS collects statistics on the data written to each journal which can be used to analyze the activity of a single region.
JVM server statistics
CICS collects statistics for JVM servers and for Java™ programs that run in JVMs. You can use these statistics to manage and tune the Java workloads that are running in your CICS regions.
LIBRARY statistics
LIBRARY statistics report resource data for dynamic program LIBRARY concatenations, which are data sets from which program load modules can be loaded.
Loader domain statistics
Logstream statistics
CICS collects statistics on the data written to each log stream which can be used to analyze the activity of a single region. However, because log streams can be shared across multiple MVS™ images, it can be more useful to examine the statistics generated by MVS.
LSR pool statistics
CICS supports the use of up to 255 LSR pools, and produces two sets of statistics for LSR pool activity: one set detailing the activity for each LSR pool, and one set giving details for each file associated with an LSR pool.
Monitoring domain statistics
You can use monitoring domain statistics to measure the amount of CPU, storage, temporary-storage requests, and other resources used, by task. This information provides a view of the performance of the CICS system.
Named counter sequence number server
Named counter sequence number server statistics are provided by the AXM page pool management routines for the pools AXMPGANY and AXMPGLOW.
NODEJSAPP statistics
You can get information about Node.js applications by inquiring on the NODEJSAPP resource. The JVM (SJ) domain collects statistics for Node.js applications, including statistics on heap storage and CPU usage. Each Node.js application is represented by a NODEJSAPP resource. These statistics can be a good starting point for managing and tuning the performance of a Node.js application.
Program autoinstall statistics
PIPELINE definition statistics
PIPELINE resource definitions are used in web services support when a CICS application is in the role of a web service provider or requester. They provide information about the message handler programs that act on a service request and on the response.
Policy statistics
CICS policies define the actions that CICS is to take when predefined conditions are met. You can use CICS policies to control the behavior of CICS during run time. CICS collects resource statistics for each rule that is defined in a policy, and supplies a summary report.
Program statistics
Program statistics report the resource data collected by the loader for each program.
Program definition statistics
Program definition statistics report the resource data collected by the Program Manager for each program.
Recovery manager statistics
Recovery manager statistics detail the sync point activity of all the transactions in the system. From these statistics, you can assess the impact of shunted UOWs (units of work that suffered an indoubt failure and are waiting for resynchronization with their recovery coordinator, or for the problem with the resources to be resolved).
Security domain statistics
CICS collects global statistics on the security domain. A summary listing of security domain statistics is also available.
Shared temporary storage queue server statistics
Shared temporary storage queue server statistics are provided by the AXM page pool management routines for the pools AXMPGANY and AXMPGLOW.
Statistics domain statistics
Statistics recording on to an SMF data set can be a CPU-intensive activity. The amount of activity depends more on the number of resources defined than the extent of their use. This is another reason to maintain CICS definitions by removing redundant or over-allocated resources.
Storage manager statistics
These statistics are produced to aid all aspects of storage management.
Table manager statistics
TCP/IP global and TCP/IP Service statistics
TCP/IP support is the basis for CICS web support and web services in CICS. Each port on which TCP/IP requests can be received is defined by a TCPIPSERVICE resource definition. The statistics include global statistics and statistics for each TCPIPSERVICE definition.
Temporary storage statistics
Temporary storage statistics are produced for the data that is written into a temporary storage queue.
Terminal control statistics
Transaction class (TCLASS) statistics
Transaction statistics
The statistics include global statistics and statistics for each transaction.
Transient data statistics
URIMAP definition statistics
URIMAP resource definitions match the URIs of HTTP or web service requests, and provide information about how to process the requests. The statistics include global statistics and statistics for each URIMAP definition.
User domain statistics
These statistics are not available online, and are mapped by the DFHUSGDS DSECT.
SNA statistics
Web service statistics
Web services support in CICS enables CICS applications to act in the role of both web service provider and web service requester, where the services are defined by using web services description language (WSDL).
CICS MQ statistics
Statistics are provided for the CICS-MQ connection and each installed MQ monitor.
XMLTRANSFORM statistics
The markup language (ML) domain collects statistics for XMLTRANSFORM resources, which define the XML binding and schema to transform application data to XML and vice versa.
