6. DATA SOURCES


The CA MICS System Reliability Analyzer processes the error
and environmental records generated by system hardware and
software and creates files in the CA MICS Database.

These records are produced by the operating systems whenever
an error or important event occurs.  Examples of these errors
are IPL of the operating system, an I/O error accessing a
DASD volume or a machine check on a processor.

These error records are written to the system error recording
data set (ERDS).  These data sets are called by different
names under various operating systems.  In MVS the ERDS is
called SYS1.LOGREC; in VM, it is not a data set but the error
recording area; in the VSE systems, its symbolic name is
LOGREC.

The CA MICS System Reliability Analyzer supports the ERDS
data from the MVS/SP, MVS/XA, MVS/ESA, OS/390, VM/SP, VM/XA,
VM/ESA and VSE operating systems.

Details of the records used by this CA MICS product are
discussed later in this chapter.
