Interactive Control Operator Commands

APPCCONTROL PERFORMANCEOFF

Disables the gathering of session statistics and performance-related

data.

Syntax

APPCCONTROL PERF[ORMANCE]OFF

Description

The APPCCONTROL PERFORMANCEOFF command disables the gathering of

APPC subsystem performance statistics.

When the APPC subsystem starts up, statistics gathering is disabled by

default. To enable statistics gathering at subsystem startup, you specify

PERFON = YES in the APPCCONTROL START command, described later in

this chapter. If you start the APPC subsystem programmatically, you

can enable statistics gathering by setting the

PerformanceOn

parameter of the APPCStart intrinsic to 1. See Chapter 3 , “Control

Operator Intrinsics,” for more information on control operator

intrinsics.

Once the APPC subsystem is active, you can enable statistics gathering

by issuing the APPCCONTROL PERFORMANCEON command, described later

in this chapter.

The APPCCONTROL PERFORMANCEOFF command is used to disable

statistics gathering once the APPC subsystem is active. Executing the

APPCCONTROL PERFORMANCEOFF command will not interrupt the

sessions for which statistics are being gathered.
