CICS® Performance
Analyzer for z/OS® (CICS PA) is a reporting tool that provides information on the
performance of your CICS systems and applications, and helps you tune, manage,
and plan your CICS systems effectively. CICS PA also provides a historical
database facility to help you manage CICS statistics and performance data
for your CICS transactions.
CICS PA is not an online monitoring tool. It produces reports and extracts
using data normally collected by your system in MVS™ System Management Facility (SMF) data sets:
- CICS Monitoring Facility (CMF) performance class, exception class, and
transaction resource class data in SMF␠110 records
- CICS statistics and server statistics data in SMF␠110
records
- CICS Transaction Gateway statistics data in SMF 111 records
- DB2® accounting data in SMF␠101 records
- WebSphere® MQ accounting data in SMF␠116 records
- System Logger data in SMF␠88 records
- IBM® Tivoli® OMEGAMON® XE for CICS on z/OS (OMEGAMON XE
for CICS) data in SMF 112 records, containing
transaction data for Adabas, CA-Datacom, CA-IDMS, and Supra
database management systems
It is designed to complement the CICS-supplied utilities and sample programs
such as DFH$MOLS, DFHSTUP, and DFH0STAT.
CICS PA can help:
- System Programmers to track overall CICS system performance and evaluate the results
of their system tuning efforts
- Application Programmers to analyze the performance of their applications
and the resources they use
- Database Administrators to analyze the usage and performance of database
systems such as IMS™ and DB2
- MQ Administrators to analyze the usage and performance of their WebSphere MQ messaging systems
- Managers to ensure transactions are meeting their required Service Levels
and measure trends to help plan future requirements and strategies
CICS PA reports all aspects of CICS system activity and resource usage, including:
- Transaction response time
- CICS system resource usage
- Cross-system performance, including multi-region operation (MRO) and advanced
program-to-program communication (APPC)
- CICS Business Transaction Services (BTS)
- CICS Web support
- External subsystems, including DB2, IMS, and WebSphere MQ
- CICS transaction usage of database management systems that
are monitored by OMEGAMON XE
for CICS: Adabas, CA-Datacom, CA-IDMS, and
Supra
- System Logger performance
- Exception events that cause performance degradation
- Transaction file and temporary storage usage
