The command CHGLSTDOM simplifies the process for changing
the host name setting of an IBM® i Sametime® Community Server.
About this task
The procedure described in this section
can also be used to correct problems with the configuration of your Sametime server. For example,
if your TCP/IP host table did not correctly list the fully qualified
host name first at the time that you setup your Sametime Community Server,
many elements of your server configuration may be incorrect. You can
correct this problem by following this procedure to change the host
name of your Sametime Community
Server.
Procedure
- Update your host table so that the new host name is associated
with the appropriate IP address. Make sure that the fully qualified
host name is listed first among the entries for your Sametime server, before
any short names. For more information, see Updating the host table on IBM i.
- Likewise, update your DNS entries so that the new host
name is associated with the appropriate IP address. Check whether
your server is configured to search the Domain Name Server (DNS) before
the host table. If it is, you must also make sure that the fully qualified
host name of your Sametime Community
Server is listed first in the DNS. To check the configured search
order, see Updating the Domain Name Server for IBM i.
- End the IBM i Sametime Community Server.
- Update the host name for the Domino® server using the
CHGDOMSVR command. For detailed information on changing the configuration
of a Domino server,
refer to Updating the configuration of existing IBM i Domino servers.
- On any IBM i command
line, type the following and press F4:
CHGLSTDOM
- On the Change Sametime on Domino display, specify
the following and then press Enter:
- The name of the IBM i Sametime Community Server
where you want to make this change (for example, stdom1).
- The new fully qualified host name for the IBM i Sametime Community Server
(for example, stdom1.acme.com).
- Updates the Ports -Notes Network
Ports - Net Address field in the Server document.
- Adds the host name to the Internet
Protocols - HTTP - Host name field in the Server document.
- Updates Sametime files that reference
the host name.
Note: If your server is enabled for both IPv4 and IPv6 addressing,
you must manually update the
sametime.ini
file so
that "VPS HOST=" is set to an explicit IP address, rather than the
host name, after running the CHGLSTDOM command. See
Configuring the
Community Services for IPv6 for detailed instructions.
- Start the IBM i Sametime Community Server.
- Open the Domino directory
(names.nsf) on your IBM i Sametime Community Server
and edit the Server document. Look at the Internet Protocols
- HTTP tab in the Server document and locate the Basics
- Host name(s) field.
- The Basics - Host name(s) field
may contain more than one name. If any of the names are incorrect
or not needed, delete them. Make sure that the correct fully qualified
host name is listed first in the field.
Note: If your server
is configured for both IPv4 and IPv6 addressing, there are additional
considerations when updating the Host name field. See
Configuring Domino for IPv6 on IBM i for detailed instructions.
- Save and close the Server document.
- If you are using HTTP Tunneling with multiple IP addresses,
then additional configuration updates are required. See "Updating
the host names when using HTTP Tunneling with multiple IP addresses"
later in this section.
- Stop and restart the IBM i Sametime Community Server
for the changes to take effect.
What to do next
Updating the IBM i
host names when using HTTP Tunneling with multiple IP addresses
If you are using HTTP Tunneling with multiple IP
addresses, then you must update your configuration manually after
using the CHGLSTDOM command to change the IBM i server host name. If you are not using
HTTP Tunneling with multiple IP addresses then this step is not applicable.
The CHGLSTDOM command placed the new host name
in the tunneling host name fields, but did not preserve the required
prefixes, such as community-, meeting- and broadcast-, in the Sametime configuration.
Use the Sametime Administration
tool to update the host names in the following fields in the "Connectivity"
section:
- Community Services Network settings
-> Address for client Connections-Host name should have
prefix of community-
- Community Services Network settings
-> Address for HTTP tunneled client Connections-Host name should
have prefix of community-
