Defining Structured Infostorage Records › DIAGLIM Record-Diagnose Limiting

DIAGLIM Record-Diagnose Limiting

The DIAGLIM VMO record specifies the diagnose requests for CA ACF2 for VM validation. You cannot reload this record. IPL the system to make any changes effective.

Fields

DIAGS(null|diag1,...,diag256)

Specifies the diagnoses CA ACF2 for VM protects when you specify the LIMIT (INCLUDE or EXCLUDE) operand. You can specify up to 256 diagnose codes.

LIMIT(ALL|NONE|INCLUDE|EXCLUDE)

Specifies how to limit the diagnoses. The values for this option are defined below.

ALL

Specifies that CA ACF2 for VM validates all diagnoses. This is the default.

NONE

Specifies that all diagnoses listed are allowed and CA ACF2 for VM does not validate any diagnoses.

INCLUDE

Indicates that CA ACF2 for VM validates the diagnoses listed.

EXCLUDE

Indicates that CA ACF2 for VM does not validate the diagnoses listed.

Here is how to use the LIMIT operand:

• LIMIT(INCLUDE) DIAGS(4,1C,80)

  Indicates that CA ACF2 for VM validates only the 4, 1C, and 80 diagnoses. It does not validate any other diagnoses.

• LIMIT(EXCLUDE) DIAGS(0,4C,6C)

  Indicates that CA ACF2 for VM does not validate the 0, 4C, and 6C diagnoses. It validates all other diagnoses.

• LIMIT(ALL) DIAGS( )

  Tells CA ACF2 for VM to validate all diagnoses. It ignores any diagnoses specified in the DIAGS( ) parameter list.

• LIMIT(NONE) DIAGS( )

  Tells CA ACF2 for VM not to limit any diagnoses. It ignores any diagnoses specified in the DIAGS( ) parameter list.

MDLTYPE(E21|mdltype)

Specifies the three‑character name that identifies the appropriate diagnose limiting rule for this VM system. E21 is the default for diagnose limiting.

MODE(ABORT|WARN|LOG|QUIET|RULE,no‑rule,no$mode)

Specifies the mode that CA ACF2 for VM diagnose limiting is performed in. With this operand, you can implement diagnose limiting gradually. However, the mode for this operand applies only to diagnose limiting and is totally independent of the CA ACF2 for VM system mode. The values for this operand are defined below.

ABORT

Indicates the diagnose is denied.

WARN

Indicates execution is allowed, but the violation is logged and a warning message is issued.

LOG

Indicates execution is allowed and the violation is logged.

QUIET

Indicates CA ACF2 for VM diagnose limiting is disabled. However, you can still issue diagnoses.

RULE,no‑rule,no$mode

Indicates CA ACF2 for VM checks the $MODE control statement in the diagnose instruction.

SHOW Subcommand

The SHOW DIAGLIM subcommand displays the current diagnose limiting options in effect for this VMO record.
