Managing APPC Sessions
This section discusses the APPCCONTROL STATUS and APPCCONTROL
SESSIONS commands.
You issue the APPCCONTROL STATUS command to check the status of the
APPC subsystem during run time.
You use the APPCCONTROL SESSIONS command to control the number of
active APPC sessions.
Checking APPC Subsystem Status
At subsystem startup, the number and characteristics of active sessions
are determined by the parameters in the APPC configuration file.
However, once the APPC subsystem is active, you can use the
APPCCONTROL SESSIONS command to change session limits and session
characteristics so that they no longer match the configuration
parameters. The APPCCONTROL STATUS command is used to get the
current status of the APPC subsystem.
The description of the APPCCONTROL STATUS command in Chapter 2 ,
“Interactive Control Operator Commands,” contains an item-by-item
description of the display. This section uses several examples to
illustrate the use of the APPCCONTROL STATUS command.
In the following example, the APPCCONTROL STATUS command is issued
with no parameters, so information is displayed for all configured
session types and all active TPs. The display shows two configured
session types: one independent and one dependent. The independent
session type, INDSESS1, has no active sessions. The dependent session
type, DEPSESS1, has two active sessions.
Each active session is being used by a separate instance of the same TP.
The TPIDs are different, indicating two different TP processes, but the
Program File Name and TP Name are the same for both processes.
