Attached controller (CTL)

Specifies the name of the controller description to which this device is attached.

Note: To use this device for communicating with a remote location that resides on the same system as the local location, specify a controller description that was created with LINKTYPE (*LOCAL) specified.

Special host application (SPCHOSTAPP)

Specifies whether SNUF customizes support for special host applications outside the Customer Information Control System for Virtual Storage (CICS/VS) or Information Management System for Virtual Storage (IMS/VS) application layer.

*NONE: SNUF does not customize support for special host applications.
*FLASH: SNUF customizes support for the Federal Reserve Flash application.

Host type (HOST)

Specifies the type of host system with which the device will communicate.

*CICS: The host system type is CICS/VS.
*IMS: The host system type is IMS/VS.
*IMSRTR: The Information Management System is the host system. RTR (return-to-ready) commands will be used in communicating with the host system.
*ADCS: The Advanced Data Communications for Stores is the host system.

Record length (RCDLEN)

Specifies the maximum record length allowed when communicating with this device.

Valid values range from 1 to 32767.

The value must be at least the size of the largest record to be sent, but must not exceed the buffer size specified on the line description (MAXBUFFER parameter) to which this device is attached.

Block length (BLKLEN)

Specifies the maximum block length allowed when communicating with this device.

The possible values are from 1 to 32767.

The value must be at least the size of the largest record to be sent, but must not exceed the buffer size specified on the line description (MAXBUFFER parameter) to which this device is attached.

Default program (DFTPGM)

Specifies the name of the program called if a program start request is received and no program is specified.

The program is specified by its qualified name (library-name/program-name).

The possible library values are:

*LIBL: All libraries in the library list for the current thread are searched until the first match is found.

*CURLIB: The current library for the thread is searched. If no library is specified as the current library for the thread, the QGPL library is searched.

library-name: Specify the library where the object is located.

HCP emulation (HCPEML)

Specifies the Host Command Processor (HCP) emulation to be performed.

3651: The host is running ADCS and will use this device description for a 3651 HCP emulated session.
3684: The host is running ADCS and will use this device description for a 3684 HCP emulated session.
4680: The host is running ADCS and will use this device description for a 4680 HCP emulated session.
4684: The host is running ADCS and will use this device description for a 4684 HCP emulated session.
*STRUSRPGM: The host is running ADCS and will use this device description for the Start User Program (SUP) emulated session.

Dependent location name (DEPLOCNAME)

Specifies the dependent local location name used for Dependent LU Requester (DLUR), providing additional security for the connection. If this name is filled in, an activation request (SNA ACTLU) from a Dependent LU Server (DLUS) node must reference this name or it is rejected.

Remote DLUS nodes may optionally accept unsolicited reply PSIDs (Product Set IDs) from the iSeries for auto-definition of LUs at the DLUS node. If so, then this name will be sent to the DLUS node in the reply PSID and it will be returned on the ACTLU request.

If unsolicited reply PSIDs are not supported by the DLUS node, then there will have to be close coordination of the PU name definitions on both systems.

*NONE: No location name is defined.
dependent-location-name: Specify the dependent location name used for DLUR applications.

Authority (AUT)

Specifies the authority you are giving to users who do not have specific authority for the object, who are not on an authorization list, and whose group profile or supplemental group profiles do not have specific authority for the object.

*CHANGE: The user can perform all operations on the object except those limited to the owner or controlled by object existence (*OBJEXIST) and object management (*OBJMGT) authorities. The user can change and perform basic functions on the object. *CHANGE authority provides object operational (*OBJOPR) authority and all data authority. If the object is an authorization list, the user cannot add, change, or remove users.

*ALL: The user can perform all operations except those limited to the owner or controlled by authorization list management (*AUTLMGT) authority. The user can control the object's existence, specify the security for the object, change the object, and perform basic functions on the object. The user also can change ownership of the object.

*USE: The user can perform basic operations on the object, such as running a program or reading a file. The user cannot change the object. Use (*USE) authority provides object operational (*OBJOPR), read (*READ), and execute (*EXECUTE) authorities.

*EXCLUDE: The user cannot access the object.

*LIBCRTAUT: The system determines the authority for the object by using the value specified for the Create authority (CRTAUT) parameter on the Create Library (CRTLIB) command for the library containing the object to be created. If the value specified for the CRTAUT parameter is changed, the new value will not affect any existing objects.

name: Specify the name of an authorization list to be used for authority to the object. Users included in the authorization list are granted authority to the object as specified in the list. The authorization list must exist when the object is created.

Examples

CRTDEVSNUF   DEVD(SNUFDEV02)  LOCADR(FE)  RMTLOCNAME(DETROIT)
             CTL(SNUFCTL01)  PGMSTRRQS(*YES)  DFTPGM(PAYROLL)

This command creates a device description for a SNUF communications device named SNUFDEV02. The device is attached to the communications controller SNUFCTL01 in Detroit, and is at location address X'FE'. The device will be program start request-capable and the default program is PAYROLL.
