Overview
IBM CICS® Performance Analyzer for z/OS V1.3 (CICS PA) a powerful offline reporting tool, produces a wide range of reports and extracts that help you tune and manage your CICS systems.
Benefits
CICS PA can help:
- Improve transaction response times and CICS system resource usage
- Analyze CICS application performance, observe the effects of increased transaction volumes, and pinpoint the variations in resource utilization that new CICS applications may cause.
- Increase availability of resources
- Increase the productivity of system and application programmers
- Evaluate whether CICS system tuning efforts produce the desired results
- Provide awareness of usage trends, assisting in future growth estimates
IBM CICS Performance Analyzer for z/OS, Version 1.3
CICS PA analysis programs use the performance and accounting data written to MVS System Management Facility (SMF) data sets. This includes the data collected by the CICS Monitoring Facility (CMF), DB2 Universal Database for z/OS and WebSphere MQ Accounting Records and the MVS System Logger. You can produce all the CICS PA reports and extracts by simply defining your CICS Systems (Applids), MVS Images, DB2 Subsystems, MVS System Logger and their associated unloaded SMF data sets. Other CICS PA data sets include Report Sets, Report Forms and Object Lists. Report Sets define your report and data extract requests. Report Forms enable you to tailor your reports and extracts to include the information that you want to see. Object Lists enable you to group objects for reporting purposes, e.g. analyse the resource usage of a particular group of transactions or users. CICS PA reports are designed to enable comprehensive analysis of your entire CICS system — with a detailed overview of transaction volume and performance — so you can evaluate resource usage and predict future usage quickly.
Comprehensive Report Analysis
The CICS reports analyze all facets of your CICS systems, including:
- CICS application performance
- CICS System Resource Usage
- Cross-system performance, including Multi-Region Operation (MRO), Advanced Program-to-Program Communication (APPC) and DB2 subsystems
- Transaction Resource Usage
- File and TSQueue resource usage
- External Subsystems used by your CICS applications including ... WebSphere® MQ®, DB2 and IMS (DBCTL)
- MVS Workload Manager (WLM)
- CICS Business Transaction Services (BTS)
- Transaction Groups
- CICS Web Support, IIOP, ECI over TCP/IP, ...
- Exception events that cause performance degradation
Reporting flexibility:
Here are some examples of reports you can produce with CICS PA:
- Transaction reports detailing all transactions processed, with the information presented in the format and order that you want
- Transaction activity reports can be tailored to produce a detailed analysis and comprehensive overview of transaction performance
- Resource usage reports show the performance and utilization of your CICS system resources, including:
- Transactions and programs
- Files
- Temporary storage
- Transient data
- Journals and logstreams
- Virtual storage
- Terminals
- BMS maps
- Secure Sockets Layer (SSL) and CICS Web support
- Java Virtual Machine (JVM) support
- SOAP for CICS
- Cross-system work reports that combine the CMF data from all of your CICS systems to evaluate the performance of Multi-Region Operation(MRO) and Advanced Program-to-Program Communication (APPC) transactions
- Transaction resource usage reports showing, at a transaction-level,the individual file and temporary storage queue resources accessed by a transaction
- Workload activity reports that show, at a glance, if the MVS WLM goals that you have set for your CICS transactions are being met
- Transaction group reports that combine the performance data of all transactions in your Transaction Groups to produce a consolidated report
- CICS Business Transaction Services (BTS) Reports that evaluate your BTS application performance
- External subsystem reports that show the performance and utilization of DB2 and IMS Data Base Control Subsystems
CICS PA offers a comprehensive extract capability that allows you to export transaction performance data to DB2 or your PC workstation for further analysis and graphical representation. Exception reports list and summarize CICS Exception Events that impact the performance of your CICS systems. Performance wait analysis reports are provided to help identify performance bottlenecks
Easy to read and use reports and data extracts
The CICS reports analyze all facets of your CICS systems, including:
- The report formatting capability of CICS PA enables you to tailor the content of your reports to meet your individual requirements
- A powerful record selection and sorting capability enables you to request the information that you want, in the order that you want it
- To help you get started quickly, CICS Performance Analyzer, Version 1.3 comes with more than 90 standard reports
You can also select a particular subset of SMF data and use it as input to CICS Performance Analyzer for faster processing.
Historical Database
The new Historical Database (HDB) provides a flexible and easy-to-use facility for collecting and managing historical performance data for your CICS systems. The CICS PA HDB function provides:
- Short-term history data detailing individual transaction performance for use in performance problem analysis
- Long-term history data summarized over time can be used for trend analysis and capacity planning
- A powerful and flexible definition facility for the historical data repositories
- Comprehensive reporting facilities
- A facility to optionally load history data into DB2 for further analysis and reporting using DB2 reporting tools such as Query Management Facility (QMF)
- Definition and management of the HDBs from the CICS PA ISPF dialog
ISPF User Interface
CICS PA provides an easy-to-use interface and extensive online help to
- create, maintain and submit report requests
- define and manage historical databases
Your customized CICS system definitions are used as a basis for the formatting of your reports. You can easily tailor reports to your specific needs, using the dialog.
You can also submit your report requests as part of any job scheduling or automation process
