Network Address and Network Port for AS/400 Connections

ID: Q246655

The information in this article applies to:

Microsoft SNA Server, versions 4.0 SP2, 4.0 SP3

SUMMARY

This articles explains how to determine the Network Address and Network Port number for the following data providers with an AS/400 over TCP/IP:

Microsoft OLE DB Provider for AS/400 and VSAM

Microsoft OLE DB Provider for DB2

Microsoft ODBC Driver for DB2

MORE INFORMATION

When you use the Microsoft OLE DB providers or ODBC Driver mentioned above, there are two possible choices for Network Transport: SNA or TCP/IP. Using TCP/IP requires a Network Address and Network Port number for communication with the host. This article describes how to locate this information for connections with AS/400 hosts.

Determining the Network Address:

From an AS/400 command line, issue the following command:
```
     NETSTAT 
```

When the following menu is displayed, choose option number 1:


     1. Work with TCP/IP interface status 
     2. Display TCP/IP route information 	 
     3. Work with TCP/IP connection status

A list similar to the following will be displayed:


           Internet        Network        Line          Interface
     Opt   Address         Address        Description   Status 	  
     __    127.0.0.1       127.0.0.0      *LOOPBACK     Active
     __    101.11.11.11    101.11.0.0     ETHERNET      Active
     __    101.12.21.21    101.12.0.0     LANLINE       Active

Locate the entry for the appropriate line description. If the line description name is not listed, use the F11 function key to toggle between the line description information and the interface status information.

Use the Internet Address entry for the appropriate line description as the Network Address setting in the Microsoft OLE DB provider or ODBC driver. A host name may also be used if the appropriate DNS or local hosts file entry has been made.

Determining the Network Port:

From an AS/400 command line, issue the following command:
```
     NETSTAT 
```

When the following menu is displayed, choose option number 3:


     1. Work with TCP/IP interface status 
     2. Display TCP/IP route information 	 
     3. Work with TCP/IP connection status

A list similar to the following will be displayed:


     Remote     Remote    Local
Opt  Address    Port      Port       Idle Time    State 
__   *          *         snmp       110:00:11    *UDP  
__   *          *         drda       001:13:15    Listen
__   *          *         ddm        001:13:15    Listen
__   *          *         ddm-ssl    001:13:15    Listen
__   *          *         as-svrmap  001:26:11    Listen

Locate the entry where Local Port is equal to drda. When you locate the entry, use the F14 function key to show the port number for the DRDA server. The well-known port number for DRDA is 446; however, this is configurable.

Use the port number listed for the DRDA server as the Network Port setting in the Microsoft OLE DB provider or ODBC driver.
