LIMIT Control Statement

The LIMIT control statement allows you to set error thresholds for EREP to use with the subsystem exception reports:
  • The values you specify on LIMIT statements control the processing of temporary and soft (nonterminating) errors.
  • The reports include data only for devices with errors that equal or exceed limits you specify.
  • You can cut down on the number of records EREP uses for the system exception reports by using the LIMIT control statements.

Indicates

The limits you want EREP to apply to temporary or soft errors produced by the device type or processor model for the system exception reports.

dasd
Is the device type designation for DASD products.
tape
Is the device type designation for tape products.
cpu
Is the machine type designation for processor products.
dkeyword
Is one or more DASD product-dependent keyword parameters with associated numeric limits.
tkeyword
Is one or more tape product-dependent keyword parameters with associated numeric limits.
ckeyword
Is one or more processor product-dependent keyword parameters with associated numeric limits.
Because the possible device types, keywords, and numeric expressions are product-specific, their descriptions are in Product-Dependent Information. See the LIMIT control statement sections of the device dependent topics shown in the following table for details:

Defaults

The default action for the LIMIT statement varies according to the product involved. See the discussions of the LIMIT statement in Product-Dependent Information.

Coding

The LIMIT statement is different for each product group. The details are in Product-Dependent Information.

Here are a few general rules that apply:
  • LIMIT must be the first word in the statement, followed by one blank, the device or machine type, and the keyword parameters, separated by commas.
  • If you code more than one LIMIT statement for a device type, EREP uses the temporary error limits set in the latest LIMIT statement; the values on a second statement override those on a previous one.

Examples

See the DASD, tape, and processor sections of Product-Dependent Information, for the details and examples of using LIMIT statements.
