Configuring a CTC device

BARR/NJE

Ask your host programmer to configure a CTC device, where BARR/NJE emulates a 3088 CTC adapter.

Sample Bus & Tag configuration

CHPID	PATH=(4E),PARTITION=((OS390),(OS390)),TYPE=BL
CNTLUNIT	CUNUMBER=0510,PATH=(4E),UNITADD=((10,008)),SHARED=N, *
	PROTOCL=S4,UNIT3088
	ADDRESS=(510,008),UNITADD=00,CUNUMBR=(0510),TIMEOUT=N, *
IODEVICE	STADET=Y,UNIT=3088

Where IODEVICE ADDRESS=(510,008). 510 is the CTC device number that will be used in the UNIT=yyyy parameter when you specify streams using the LINE() and NODE() macros.

Sample ESCON configuration

CHPID	PATH=(45),PARTITION=((OS390),(OS390)),TYPE=CNC
CNTLUNIT	CUNUMBER=4510,PATH=(45),UNITADD=((10,001)),UNIT=SCTC
IODEVICE	ADDRESS=(4510,001),CUNUMBR=(4510),STADET=Y,UNIT=SCTC

Where IODEVICE ADDRESS=(4510,001). 4510 is the CTC device number that will be used in the UNIT=yyyy parameter when you specify streams using the LINE() and NODE() macros.

Sample VM/VSE configuration

The CTC connection for the Barr Enterprise Print Server must be added both in the virtual machine (VM) and in VSE. Examples are shown for defining the CTC connection at device address A number that uniquely identifies a device. D10. See the IBM manual, VS/ESA Planning and Administration, for more information.

Define connections

Bus & Tag CTC connections must be defined to VM in your SYSTEM CONFIG file. Use this RDEVICE statement to define one or more CTC adapters to the control program (CP).

If you are using an ESCON CTC connection, you can skip this procedure. ESCON CTC connections are automatically identified by the VM.

RDEVICE D10 TYPE CTCA

Parameter	Description
RDEVICE D10	D10 is the real device number of the CTC adapter that you want defined. Each RDEVICE must be a hexadecimal number between X'0000' and X'FFFF'.
TYPE CTCA	Tells CP that the real device that you are defining is a CTC adapter.

Specify the 3737 Remote CTC Unit Model 2 as a CTCA.

Dedicate to a virtual machine

The CTC is then dedicated to VSE in the USER DIRECT file entry for the VSE VM. The DEDICATE statement specifies that a VSE has sole use of a real device.

DEDICATE
D10 D10

The first D10 is used to dedicate the virtual device number. The second D10 is used to dedicate the real device number.

Add channel-attached devices

The BARR/NJE CTC connection is defined in the VSE/ESA IPL procedure. The following example shows how to add channel-attached devices to VSE.

ADD D10,CTCA,EML BARR/NJE CTC TO POWER

Parameter	Description
D10	The device number of the CTC adapter.
CTCA	Indicates the device type.
EML	Indicates that the device type, as specified by the user, will be used to assign the VSE device type code. The EML operand causes IPL to ignore device type sensing, and add the device as the type specified in the ADD command.
