Processor (CPU) Subsystem Exception

The processor (CPU) subsystem exception report is organized by service level for:

TYPE	DESCRIPTION
Termination errors	The total number of incidents and the date and time of the last incident are shown for termination errors and hard errors.
Hard errors
Soft machine checks	The total number of 60-minute intervals in which the number of events that occur equals or exceeds the LIMIT values is shown for soft machine checks. The LIMIT value is set by the LIMIT control statement, which sets the minimum number of errors (1–99). When the minimum has been reached, errors are recorded in the `EXCEPTION COUNT` column.

Figure 1 shows an example of the processor subsystem exception report.

This space is used for self-explanatory SCP and device-dependent messages specific to this subsystem exception report. For example:

** WARNING ** REPORT SPANS MORE THAN 3 DAYS

This report is provided for the following CPUs only:

0158
0168
3031
3032
3033

3

The types of errors are:

TERMINATION ERROR
HARD ERROR
SOFT MACHINE CHECK

4

The count of input records containing this particular error.

5

Date and time of the last MCH record that includes this error. If the date and time are the same for several service level indicators, it means that a single record includes all the indicators.

6

The number of 60-minute intervals in which the number of events that occur equals or exceeds the LIMIT values for each type of soft machine check.

7

The LIMIT values applied to this report. If the LIMIT value is zero, the EXCEPTION COUNT field is also zero.

8

Execution-time notes. These may be:

NOTE	DESCRIPTION
nn `UNITS EXCLUDED DUE TO LIMITS`	If LIMIT values are present
nn `MCH RECORDS PROCESSED`	Number of valid MCH records processed
nn `MCH RECORDS UNDEFINED`	Not identifiable to EREP as valid MCH records
nn `MCH RECORDS IGNORED DUE TO CCH DUPLICATION`	0158 models only, from which MCH records might be double-reporting an assumed channel failure
