The CA MICS System Reliability Analyzer produces reports
using the batch and interactive reporting facilities of the
CA MICS I/S Management Support System. The reports can be
categorized as MICF inquiry, standard analysis, and exception
reports.
MICF inquiries are printer reports and color graphics that
are accessed via the CA MICS Information Center Facility
(MICF). MICF inquiries produce meaningful reports from the
CA MICS Data Base and provide you with the flexibility to
code and save your own report formats.
CA MICS standard analysis reports provide a concise
representation of an installation's workload, resource use,
and response to the workload.
Exception reports contain an integrated and itemized list of
the problems impacting an installation's effectiveness in
terms of availability, service, workload, standards,
security, and performance. Exception reports are discussed
in Chapter 4 of this guide.
The Standard Reports available under MICF can be classified
under four main categories. They are:
o System Reliability Analysis
o Software Reliability Analysis
o Hardware Reliability Analysis
o Media Reliability Analysis
SYSTEM RELIABILITY ANALYSIS
One report makes up this category: the System Reliability
Summary Report. The System Reliability Summary Report
provides an overview of the key errors and events that have
occurred for the processor, associated storage and channels,
and the software, hardware devices, and magnetic media.
Counts of the number of failures and other significant events
are provided by a unique system identifier.
SOFTWARE RELIABILITY ANALYSIS
The reports contained within this category are the System
Software Malfunction Summary Report, the Module Failure Trend
Analysis Report, and the Abend Trend Analysis Report.
The System Software Malfunction Summary Report summarizes the
software failures occurring on each system by both system and
user completion code. The report includes information such
as job name, module name, CSECT name, and functional recovery
routine name. In addition, an indication is provided if the
job or module has been designated as critical to the
installation. A textual description of the system completion
code is also provided.
The Module Failure Trend Analysis Report provides a history
of software failures by module over a user specified period
of time, such as seven days. This allows you to track
modules which repeatedly fail over some period of time.
The Abend Trend Analysis Report provides a history of
software failures by system abend code over a user specified
period of time, such as seven days. This allows you to track
failures of the same type that repeatedly occur over some
period of time.
HARDWARE RELIABILITY ANALYSIS
The reports within this category are the Equipment
Reliability Summary Report and the Device Reliability Trend
Report.
The Equipment Reliability Summary Report provides a summary
of equipment failures by device class and device type for the
current period and a specified previous period of time. The
comparison provides a usage count (SIO operations, seeks,
...), a permanent and temporary error count, and the ratio of
usage to permanent and temporary errors for the two periods.
The Device Reliability Trend Report provides a trend history
of the temporary failures that have occurred by specific
device address over a period of time up to 10 days. The
temporary error failure history is reported by device class
(DASD), device type (3350), and device address (254) over the
selected period.
MEDIA RELIABILITY ANALYSIS
The reports in this category are the Magnetic Tape Media
Reliability Report and the Direct Access Media Reliability
Report.
The Magnetic Tape Media Reliability Report provides a summary
of tape media usage statistics and failures by volume for the
current period and comparative failure counts for a specified
previous period of time. The usage statistics include number
of mounts, Start I/O count, and number of permanent read and
write errors. The comparative failure data includes the
number of temporary read and write errors and the ratio of
Start I/O operations to temporary errors.
The Direct Access Media Reliability Report provides a summary
of disk media usage statistics and failures by volume for the
current period and comparative failure counts for a specified
previous period of time. The usage statistics include number
of seeks and millions of bytes read and the failure data
includes the number of seek checks, number of reads recovered
by a retry operation, and the number of reads recovered by
the error checking and correction circuitry. The three
failure counts represent temporary read errors which were
corrected by the hardware or software. The comparative
failure data includes the ratio of seeks to seek checks and
the ratio of temporary errors to millions of bytes read.
