Connect to Mainframe | Applications | SNA Server 4.0 |

Example Background

The following example uses a complex connection path to provide as much information as might be found in a typical real-world environment. The example has been installed, tested and worked flawlessly.

The instructions on this page will assume the following:

Connectivity Path

• SNA Server is running on an NT Server computer which has a network card
• the network card is connected to an Ascend "Pipeline 50" Router
• This router connects to an off-site location also having a "Pipeline 50" Ascend router
• This router connects to a Hub
• This Hub connects to Cisco 2600 router
• This router connects to the mainframe Front End Processor (FEP) using Frame Relay

 

Preliminary steps

Contact the administrator of the mainframe

Have the mainframe administrator "gen" a connection to the mainframe for one or more Display LUs and for printer connections if needed. You in turn should receive the following

• The Mainframe address - i.e. M123456S
• The mainframe PU address - i.e. P123456S
• The MAXDATA = xxx value (i.e. MAXDATA=521 )
• the 12 digit Remote Network Address ( i.e. 400009900009 )
• the IDBLK = xxx ( i.e. IDBLK=05D ) a.k.a. local node ID
• the IDNUM = xxxxx ( i.e. IDNUM = 93555 ) a.k.a. local node ID
• the Remote SAP address ( most likely 0x04 )
• Local Node Name
  • The Network Name xxxx ( i.e. APPC )
  • The Control Point Name ( i.e. C991234 )

Server Configuration

Make sure the SnaDLC1 Link Service is installed and active

Open The SNA Server "Manager"

Click Start | Programs | SNA Server |

Select "Manager" from the selection

Create a new connection

Click the (+) sign in front of the Server Name to open the server

Click the (+) sign in front of the SNA Service to open the SNA Service

Click the (+) sign in front of the Connections selection to open the Connections

Right Click the Connections selection, a pop-up will appear

Select | Insert | Connection | 802.2 |

Fill in the information as in the following example (replacing the data with that provided to you by the mainframe administrator)

Click the "Address" tab at the top of the window.

Fill in the Remote Network Address information provided to you by the mainframe administrator and if needed change the Local SAP address ( this will be grayed out if the configuration selection is "Fixed")

Click on the "System Identification" tab on the top of the window

Fill in the information provided to you by the mainframe administrator as shown below.

Click the "802.2 DLC" tab on the top of the window, and fill in the "MAX BTU length" value given to you by the mainframe administrator as shown below.

Click the OK button to finish the entry.

A new entry will now appear under "Connections" ( in this example the entry is named APPC)

To add a single LU, right click on the entry and select | Insert | 3270 | Display LU |

Type in the LU number (i.e. 2 ) and the LU name (i.e. My_Connection2 )

To add a range of LUs...

Make sure the connection name is highlighted

From the top menu select | Insert | 3270 | Range of  LUs... |

The "LU Creation Wizard" window will appear.

The sub domain name, server and connection name should appear and should be correct.

Click the "Next" Button, the next screen will appear

Type a short description in the "Base LU Name" box (in this case the letters "SES" were used). This will be the base which will be used to form all the LU names. Change the "First LU Number" if necessary and fill in the number of LUs desired.

Finally press the "Finish" button to finish the entry.

A range of LUs will be created under the Connection name.
