Note The information in this chapter applies to both UNIX workstations (Maps and SNA View) and Windows NT systems (SNA View). |
This appendix provides a list of the parameters that must be coordinated between the mainframe configuration and the workstation configuration. Cisco recommends that mainframe or workstation installers agree on these values before the mainframe or workstation installation is started.
This appendix provides information about the following two types of parameters:
The following table lists the TCP/IP parameters that configure TCP/IP connection between the mainframe and the workstation. On UNIX workstations, these parameters are contained in the /etc/svopen_config_DOMAINNAME file that you configure using a text editor. The related mainframe parameters are set using the TCP parameter card in the NSPPARM member. The following worksheet lists the TCP/IP configuration parameters.
On Windows NT systems, use the Configuration application. For more information, see "Using CiscoWorks Blue SNA View Configuration for Windows NT."
| TCP/IP host name or address of the mainframe: |
|
Mainframe value: | ______________________________ |
Workstation value: SVMF_AGENT_ADDR= | ______________________________ |
Default: | None |
|
|
| Connection protocol: |
|
Mainframe value: | TCP parameter card |
Workstation value: SVMF_CONNECT= | TCP |
Default: | None |
|
|
| Host connection interface port: |
|
Mainframe value: | ______________________________ |
Workstation value: SVMF_HCI_AGENT_PORT= | TCP HCS_port ______________ |
Default: | 6104 |
|
|
| Host command server port: |
|
Mainframe value: |
|
Workstation value: SVMF_CMDS_AGENT_PORT= | TCP ________________ HCS_port |
Default: | 6105 |
The TCP/IP address of the mainframe is the host name or IP address of the mainframe on which the mainframe application is installed. Use the SVMF_AGENT_ADDR parameter in the workstation /etc/vopen_config_DOMAINNAME file.
The connection protocol is the communication protocol between the mainframe and the workstation. The SVMF_CONNECT parameter indicates whether the workstation will connect to the mainframe using TCP/IP. To connect via TCP/IP, specify SVMF_CONNECT = TCP in the workstation /etc/svopen_config_DOMAINNAME file and provide a TCP parameter card at the mainframe.
The host connection interface port is the port number used by the host connection interface. Use this port number in the SVMF_HCI_AGENT_PORT parameter in the workstation /etc/svopen_config_DOMAINNAME file and on the mainframe TCP parameter card.
The host command server port is the port number used by the host command server. Use this port number in the SVMF_CMD_AGENT_PORT parameter in the workstation /etc/svopen_config_DOMAINNAME file and on the mainframe TCP parameter card.
Use the TCP parameter card at the mainframe to identify the ports to be used for the host command server and the host connection interface. The TCP parameter card has the following format:
TCP hciport cmdport
Where:
hciport is the port for the host connection interface (usually 6104).
cmdport is the port for the host command server (usually 6105).
For UNIX workstations, this section describes an additional set of parameters for connecting UNIX workstations to the mainframe using LU 6.2. The following worksheet lists the LU 6.2 parameters.
|
Note Before you configure LU 6.2, the mainframe and workstation must be already configured to support an LU 6.2 connection between them. The mainframe application configuration adds only the information necessary for the workstation application to communicate with the mainframe application. Items like the Remote Link address have been omitted, since this should be already configured. |
Connection protocol: |
|
Mainframe value: | LU62 parameter card |
Workstation value: SVMF_CONNECT= | LU62 |
Default: | None |
Secondary independent LU: |
|
Mainframe value: | _______________________________ |
Workstation value: | ______________________________ |
Default: | None |
Log mode: |
|
Mainframe value: | PARALLEL |
Workstation value: | PARALLEL |
Default: | PARALLEL |
Message transaction program: |
|
Mainframe value: | NSPOPNMS |
Workstation value: | NSPOPNMS |
Default: | NSPOPNMS |
Command transaction program: |
|
Mainframe value: | NSPOPNCS |
Workstation value: | NSPOPNCS |
Default: | NSPOPNCS |
The connection protocol is the communication protocol between the mainframe and the workstation. The SVMF_CONNECT parameter indicates whether the workstation will connect to the mainframe using LU 6.2. To connect via TCP/IP, specify SVMF_CONNECT=LU62 in the /etc/svopen_config_DOMAINNAME file and provide a TCP parameter card at the mainframe.
The logmode specifies the VTAM logmode entry. Use PARALLEL on the SERVER parameter card.
The message transaction program identifies the workstation message server transaction program (MESSAGE_TP). Code NSPOPNMS on the SERVER parameter card.
The command transaction program identifies the workstation command server transaction program (COMMAND_TP). Code NSPOPNCS on the SERVER parameter card.
You specify the mainframe parameters on the SERVER card in the NSPPARM member in the mainframe samples data set:
SERVER plu slu PARALLEL NSPOPNMS NSPOPNCS
Where:
plu is the label of the VTAM APPL definition that you coded with APPC=YES, that is the primary LU for the mainframe.
slu is the label of a CDRSC for the independent secondary LU defined for the workstation and associated with the workstation application PU.
PARALLEL is the logmode.
NSPOPNMS is the name of the SNA LU 6.2 transaction program for the workstation message server (MESSAGE_TP). You must use NSPOPNMS.
NSPOPNCS is the name of the SNA LU 6.2 transaction program for the workstation command server (COMMAND_TP). You must use NSPOPNCS.
On the workstation, configure LU 6.2 workstation parameters using the SNA package (Communications Server for AIX or SNAplusLink). Use the following values:
