Explanation of terms

An explanation of the terms used in the configuration worksheet.

1 Command prefix

This term is the unique command prefix of the IBM MQ for z/OS queue manager subsystem. The z/OS system programmer defines this value at installation time, in SYS1.PARMLIB(IEFSSNss), and can tell you the value.

2 Network ID

The VTAM startup procedure in your installation is partly customized by the ATCSTRxx member of the data set referenced by the DDNAME VTAMLST. The Network ID is the value specified for the NETID parameter in this member. For Network ID, we must specify the name of the NETID that owns the IBM MQ communications subsystem. Your network administrator can tell you the value.

3 Node name

VTAM, being a low-entry network node, does not have a Control Point name for Advanced Peer-to-Peer Networking (APPN) use. It does however have a system services control point name (SSCPNAME). For node name, we must specify the name of the SSCP that owns the IBM MQ communications subsystem. This value is defined in the same ATCSTRxx member as the Network ID. Your network administrator can tell you the value.

9 Local LU name

A logical unit (LU) is software that serves as an interface or translator between a transaction program and the network. It manages the exchange of data between transaction programs. The local LU name is the unique VTAM APPLID of this IBM MQ subsystem. Your network administrator can tell you this value.

11 12 13 Symbolic destination

This term is the name you give to the CPI-C side information profile. You need a side information entry for each LU 6.2 listener.

6 14 Modename

This term is the name given to the set of parameters that control the LU 6.2 conversation. An entry with this name and similar attributes must be defined at each end of the session. In VTAM, this corresponds to a mode table entry. You network administrator can assign this table entry to you.

7 15 Transaction Program name

IBM MQ applications trying to converse with this queue manager specify a symbolic name for the program to be run at the receiving end. This has been specified in the TPNAME attribute on the channel definition at the sender. For simplicity, wherever possible use a transaction program name of MQSERIES, or in the case of a connection to VSE/ESA, where the length is limited to 4 bytes, use MQTP.

See Defining an LU6.2 connection for z/OS using APPC/MVS for more information.

8 LAN destination address

This term is the LAN destination address that your partner nodes use to communicate with this host. When we are using a 3745 network controller, it is the value specified in the LOCADD parameter for the line definition to which your partner is physically connected. If your partner nodes use other devices such as 317X or 6611 devices, the address is set during the customization of those devices. Your network administrator can tell you this value.

10 Generic resource name

A generic resource name is a unique name assigned to a group of LU names used by the channel initiators in a queue sharing group.

16 Partner LU name

This term is the LU name of the IBM MQ queue manager on the system with which we are setting up communication. This value is specified in the side information entry for the remote partner.

21 Remote node ID

For a connection to Windows, this ID is the ID of the local node on the Windows system with which we are setting up communication.
