This hint and tip lists considerations to keep in mind when you are planning an installation of IBM Lotus Virtual Classroom.
Before you install IBM Lotus Virtual Classroom, be aware of the following considerations:
The installation process outlined in IBM Redbook SG24-6842-01 assumes that all servers in the IBM Lotus Virtual Classroom “server bed” are within the same firewall, and generally on the same network router segment. Clients will likely be connecting from outside the network segment where the servers reside.
Virtual Classroom can be configured to operate in a 512 encryption environment. The configuration procedures are outlined in Sametime and QuickPlace documentation.
Server IP address
You cannot change the IP address of a server after installing IBM Lotus Virtual Classroom. (If you do, you may receive a “Page not found” error.)
Supported version of Domino
The only supported version of Domino is 5.0.10.
Other versions of Domino have not been tested with the IBM Lotus Virtual Classroom.
IBM Lotus Virtual Classroom cannot be installed in an existing Domino domain, or on an existing Domino server.
However, an existing Domino server can be used as an external LDAP directory, provided that the server is running the LDAP task.
IBM Lotus Virtual Classroom must be installed on a new QuickPlace Server.
External LDAP directory
An external LDAP directory server cannot run on the same machine as IBM Lotus Virtual Classroom.
Setting the server screen resolution
Make sure that your screen resolution is set to at least 256 colors (required by the InstallShield installation package).
If you keep a lower resolution, the installation of QuickPlace, Sametime, and IBM Lotus Virtual Classroom may exit unexpectedly after asking you for the setup language.
Before you begin
1. Disable any Web servers running on the machines (Microsoft IIS, for example).
2. Use lowercase when naming servers (for example, use itsolvc-sess.company.com instead of LVC-sess.company.com).
3. The servers must have a fixed IP address. (Note: As mentioned, you cannot change the IP address of a server after installing IBM Lotus Virtual Classroom. If you do, you may receive a “Page not found” error.)
4. If you are using Windows 2000, make sure the computer’s Network Identification contains the DNS domain name (for example, ‘itsolvc-sess.company.com' and not simply: ‘sess'). You can get to Network Identification by right-clicking the My Computer icon, selecting Properties, and clicking the Network Identification tab. (Note: The name that you choose for your for server’s Network Identification will be reflected in the Domino server name.)
5. Both servers must be registered in the Domain Name System. (Note: As a temporary workaround, you can create entries in the local hosts files of these computers and every computer that someone uses to connect to them. For example, add lines like the following to C:\WINNT\System32\Drivers\etc\hosts (for Windows NT, 2000, and XP Professional) or C:\Windows\hosts (for Windows 98) and substitute your computer names and TCP/IP addresses):
18.104.22.168 itsolvc-cat.company.com catalog
22.214.171.124 itsolvc-sess.company.com session
