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 Facilities (SMF) data sets
and log streams:
- 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
