In this manual the term BS2000 console is used when operating the monitor system or another guest system via an emulated console screen is meant.
Where necessary, BS2000 consoles are subdivided into:
KVP consoles (see "Operating the guest systems using KVP consoles")
The operator obtains access to the operator functions of a guest system through the emulation of a console screen on the SE Manager by the KVP (console distribution program).KVP consoles can be used in VM2000 operation:
for IPL, startup and operating in the monitor system and in the other guest systems
to operate the VM2000 system as a whole, e.g. when BCAM is not active in the monitor system
Logical consoles (see "Operating the guest systems using logical consoles")
Logical consoles can be used in VM2000 operation:
for operation in the monitor system and in the other guest systems when BCAM is active in the system concerned
to operate the VM2000 system as a whole, when BCAM is active in the monitor system
You are recommended to operate the guest systems using KVP consoles or logical consoles.
Authorization code “9” is required for operating the whole VM2000 system via a BS2000 console of the monitor system.
All VM2000 commands have the authorization code “9”. All VM2000 messages have the routing code “9”. Only VM2000 commands can be entered and only VM2000 messages can be received on a BS2000 console that only has the authorization code “9”. A BS2000 console like this is therefore on a par with the administration dialog of the VM2000 administrator.
VC dialog via $VMCONS (see "Operating the guest systems (VC dialog via $VMCONS)")
This operating method is no longer recommended.Virtual consoles can be used in VM2000 operation:
for operation in the guest systems when BCAM is active in the monitor system, but not for the monitor system.
Operating guest systems via KVP consoles or logical consoles offers the following advantages compared to operating in a VC dialog:
Direct communication with the guest system
Guest system operation even if the data communication system is not available in the monitor system (e.g. in the case of an automatic restart of the monitor system).
Uniform operation of the guest systems and the monitor system.
