6. DATA SOURCES

The successful creation, maintenance, and longevity of a
large database system such as CA MICS requires a closely
monitored approach to the periodic updating processes.
Understanding the data source used in the database update
process is particularly important for the CA MICS Batch and
Operations Analyzer.  The intent of this chapter is to help
you understand the SMF data sources and to aid in the
decision-making process used to tailor SMF data recording at
your site.

This chapter discusses operational considerations for both
the SMF data collection process and the CA MICS Batch and
Operations Analyzer.  General information is given about SMF
data and specific information is given about those SMF
records used by the CA MICS Batch and Operations Analyzer.

This chapter contains the following sections:

    1 - SMF Data
    2 - Data Collector and Processing Considerations
    3 - CA MICS SMF Requirements and Considerations
    4 - CPU Time Measurements
    5 - Batch Turnaround/Response Time
    6 - I/O Measurements and Device Activity
    7 - Memory Measurements
    8 - Print Activity Measurements
    9 - SMF Record Descriptions
   10 - APPC/MVS Overview
   11 - UNIX System Services (USS) Overview
   12 - Multisystem Enclaves Overview
   13 - CA MICS and CA SMF Director Interface
