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
CICS TS provides a set of asynchronous API commands that allow application developers to use asynchronous programming model that can run child tasks asynchronously. 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. These statistics are obtained as interval , end-of-day , or requested statistics. CICS also records unsolicited autoinstall statistics, which DFHSTUP prints in a separate report.
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.
CICS MQ statistics
Statistics are provided for the CICS-MQ connection and each installed MQ monitor.
Cipher statistics
You can use the cipher statistics to identify the ciphers currently in use. This information can help you determine whether ciphers are unused, or if you need to remove a cipher, identify when it is used.
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
Dispatcher domain statistics provide important sources of information for monitoring and tuning the performance of CICS dispatcher. This reference describes dispatcher domain statistics in details.
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. Usage statistics are provided for each document template.
Dump domain: System dump statistics
The dump domain collects global and resource statistics for both system and transaction dumps which occur during the CICS run. Both transaction and system dumps are very expensive and should be thoroughly investigated and eliminated. This reference gives you details of system dump statistics.
Dump domain: Transaction dump statistics
The dump domain collects global and resource statistics for both system and transaction dumps which occur during the CICS run. Both transaction and system dumps are very expensive and should be thoroughly investigated and eliminated. This reference gives you details of transaction dump statistics.
Enqueue domain statistics
The enqueue domain supports the CICS recovery manager. The enqueue domain collects global statistics for enqueue requests. Waiting for an enqueue on a resource can add significant delays in the execution of a transaction. The enqueue statistics allow you to assess the impact of waiting for enqueues in the system and the impact of retained enqueues on waiters. Both the current activity and the activity since the last reset are available.
Event processing statistics
Event processing statistics provide important sources of information for monitoring performance. Statistics are collected on the capture specifications for each event, for event processing adapters, for event bindings, and on event processing.
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
The ISC/IRC attach time statistics of the DFHSTUP listing is for a CICS system using intersystem communication or interregion communication. It provides summary statistics for the number of times that the entries on the Persistent Verification signed on from list are either reused or timed out. Using this data you can adjust the USRDELAY and PVDELAY system initialization parameters.
IPCONN statistics
IPCONN statistics are important source of information for monitoring performance and system diagnosis. This reference describes IPCONN statistics in details.
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
Loader domain statistics provide important sources of information for monitoring performance and tuning. This reference describes loader domain statistics in details.
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 z/OS® images, it can be more useful to examine the statistics generated by z/OS.
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
CICS collects global statistics on program autoinstall. This reference describes program autoinstall statistics in details.
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 on 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 help with all aspects of storage management.
Table manager statistics
The table manager controls the locating, adding, deleting, locking, and unlocking of entries in certain CICS tables. For table management, CICS collects statistics, for each table, on the amount of storage used by the table manager to support each table, excluding storage used for the tables themselves.
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
There are a number of ways in which terminal statistics are important for performance analysis. From them, you can get the number of inputs and outputs, that is, the loading of the system by users. Line-transmission faults and transaction faults are shown (these both have a negative influence on performance behavior).
Transaction class (TCLASS) statistics
Transaction class (TCLASS) statistics are provided by the Transaction Manager domain. This reference describes transaction class statistics in details.
Transaction statistics
The statistics include global statistics from the transaction manager and resource statistics for each transaction. Transaction statistics help you find out storage usage by transactions and identify storage issues and violations.
Transient data statistics
CICS collects global and resource statistics on transient data. This reference describes transient data statistics in details and gives you statistics interpretation tips.
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 resource statistics for each URIMAP definition.
User domain statistics
These statistics are not available online, and are mapped by the DFHUSGDS DSECT.
SNA statistics
These statistics provide important sources of information for problem determination that involves z/OS Communications Server. This reference describes SNA statistics in details and helps you understand the 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). WEBSERVICE resource definitions are used to define aspects of the runtime environment for CICS application programs deployed in a web services setting. Statistics are provided for each WEBSERVICE resource definition, and a total use count for all WEBSERVICE definitions is also available.
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.
