CICS PA provides
a menu-driven dialog to request generation of reports and extracts
for analyzing and tuning the performance of your CICS® Transaction Server systems. CICS Monitoring Facility (CMF) performance class,
exception class, and transaction resource class data in MVS™ System Monitoring Facility (SMF) files provide
the input to the CICS PA reports
and extracts. In addition, DB2® and MQ accounting, System Logger, and OMEGAMON® XE
for CICS records
in SMF files are analyzed by specific reports.
Facilities are provided to help you to specify your input files,
filter the data, and tailor the reports and extracts to suit your
requirements.
The dialog requires no special customization or setup. Reporting
can commence immediately.
To get started with using CICS PA to
analyze the performance of your CICS systems
and applications, proceed as follows: - Before installing CICS PA,
check that the system requirements are met. See CICS PA system requirements.
- To install CICS PA,
follow the instructions in the Program Directory. Then to complete
the installation, see Installing the CICS PA dialog.
- If you are unfamiliar with System Monitoring Facility (SMF) data
and how to prepare it for CICS PA reporting,
see SMF data used by CICS PA.
- To get started with using the CICS PA dialog
to define and run report and extract requests, see How to use the dialog.
By following the topic
on 'Defining a Report Set for daily monitoring' in the CICS Performance
Analyzer for z/OS® Getting Started Guide you
can quickly get an insight into how to use the dialog.
The
Performance Totals report is a useful starting point as it is only
a few pages and can provide an immediate indication of which area
to look into next. Another good report to try is the Performance Summary
report with the data summarized by Transaction ID within APPLID.
- To understand the JCL generated by the dialog, or set up your
own jobs, see JCL for reports and extracts.
Sample jobs for
each report and extract are provided in Sample library.
- To understand the CICS PA commands
generated by the dialog or to code them directly in your job stream,
see Using the CICS PA commands. This chapter includes many
syntax examples and sample reports.
- For help analyzing the report and extract output, and interpreting
the CMF performance and exception data, see the CICS Performance
Analyzer for z/OS Report Reference.
- If results are not as expected, see Messages,
and Problem determination to help you diagnose
and resolve problems.
- To define and populate a historical database for analyzing
performance over time, refer to Guided Tour: Performance HDB.
