The CA MICS Hardware and SCP Analyzer supports the standard
CA MICS exception process. CA MICS exception processing
enables the IT organization to focus on problems affecting
its effectiveness in terms of availability, service,
workload, standards, security, and performance for the
different areas of responsibility (such as batch, TSO/E, or
IMS).
The standard exceptions for this product are shown in Figures
4-1 and 4-2. Each standard exception test is shipped with
default values. However, to make effective use of the
exception process, you must evaluate your needs and modify
these sample values accordingly.
This chapter contains information on the following topics:
1 - Exception Process Overview
2 - Setting Exception Values
3 - Detailed Exception Descriptions
