CHAPTER 4 PLANNING THE DOMINO FOR SYSTEM I ENVIRONMENT


Verifying TCP/IP setup and status
The Domino server on i5/OS communicates with Notes workstations and other external resources such as the Internet through TCP/IP. For the Domino server to work properly, TCP/IP must be set up and active on your system.

TCP/IP configuration greatly impacts server performance. For more information on tuning your network for optimal performance, see the book iSeries: Networking TCP/IP setup. You can access this book online at


Determining if TCP/IP is set up

TCP/IP may already be set up on your system. To verify that it is set up as needed for the Domino server, follow these steps using iSeries Navigator:

1. Open the system where you installed Domino.

2. Click Network.

3. Click TCP/IP Configuration.

4. Click IPV4 or IPV6.

5. Click Interfaces.

6. In the right-hand pane, you will see a list of TCP/IP interfaces configured on the system. Look for an Internet address that does not have a line name or description of Loopback.


Tip You can also use the CFGTCP command to determine if TCP/IP is set up. From the Configure TCP/IP display, select option 1 (Work with TCP/IP interfaces).

Determining the Internet address and host name to use for Domino

1. Record an Internet address from the previous procedure that is not associated with Loopback.


2. Find the host name that is associated with the Internet address: 3. Record the TCP/IP host name you will use for the Domino server.

By using an existing host name and Internet address for the Domino server, you can take advantage of the existing TCP/IP configuration and avoid additional configuration.

Tip You can also use the CFGTCP command to determine the Internet address and host name to use for Domino. From the Configure TCP/IP display, select option 10 (Work with TCP/IP Host Table Entries).

Starting TCP/IP

Once TCP/IP is set up for your system, make sure TCP/IP is started. To start TCP/IP using iSeries Navigator, follow these steps:

1. Open the system where you installed Domino.

2. Click Network.

3. Click TCP/IP Configuration.

4. Click IPV4 or IPV6.

5. Click Interfaces.

6. In the right-hand pane, right-click the TCP/IP interface you will use for your Domino server and select Start.

7. Periodically press F5 to refresh your screen and wait for the TCP/IP status to be Started.

Tip You can also use the CFGTCP command to start TCP/IP. From the Configure TCP/IP display, select option 1, then type a 9 next to the TCP/IP address you want to start, and press Enter.

Note If TCP/IP is already started, the system responds with a message that indicates TCP/IP is currently active.

Verifying TCP/IP interface status

To verify the status of any TCP/IP interface on your system using iSeries Navigator, follow these steps:

1. Open the system where you installed Domino.

2. Click Network.

3. Click TCP/IP Configuration.

4. Click IPV4 or IPV6.

5. Click Interfaces.

In the right-hand pane, you will see a list of all the TCP/IP interfaces configured on the system. Look under the Status column to determine the status of the TCP/IP interface.

Tip You can also use the CFGTCP command to determine the status of your TCP/IP interface. From the Configure TCP/IP display, select option 1, then type a 5 next to the TCP/IP interface.
