Before the example environment is built, certain configuration information has to be agreed so that the servers can integrate with each other easily. This section describes the prerequisites for setting up the integrated environment.
For consistency and simplicity, the specification for all of the servers in the example environment is the same:
|Processor||Dual Core |
|Operating System||Windows Server 2008 R2 64 bit|
The hard disk is divided into three separate logical disks each with a with specific purpose:
- C:\ (40Gb) contains the operating system.
- E:\ (40Gb) contains the installed programs.
- F:\ (20Gb) contains the install kits.
DNS and host names
In order for single sign-on to work across the integrated environment, the servers are all configured as part of the same domain demos.ibm.com
To make it simple to identify the servers, each server is given a host name that reflects the main product that is installed. In addition, since there is more than one Sametime service running on each of the Sametime servers, aliases are assigned to each Sametime service so that it is easy to distinguish between them in the configuration.
Server names and functions are displayed in the following table:
|domino.demos.ibm.com||Domino LDAP and iNotes server|
|quickr.demos.ibm.com||Quickr Domino server|
|sametime.demos.ibm.com||Sametime Community server|
|Sametime Proxy server||webchat.demos.ibm.com|
|Sametime Console server||ssc.demos.ibm.com|
|collab.demos.ibm.com||Sametime Meeting server||meeting.demos.ibm.com|
|Sametime Media server||media.demos.ibm.com|
Because the servers are not registered with a DNS server, these host names are configured in the Computer properties (Control Panel > System and Security > System
) as shown below.
An entry is added for each server in the hosts file (C:\Windows\system32\drivers\etc\hosts) on each computer so that the servers can locate and communicate with each other.
We recommend that the installation directory in all of the installations is edited to remove "Program Files" and any other additional directory names from the path that do not add value to the structure or organization of the program.
"\Program Files\IBM\SQLLIB\" becomes "\IBM\SQLLIB"
"\Program Files\IBM\Lotus\Domino" becomes "\Lotus\Domino"
Reasons for this recommendation:
- There are situations where spaces in path names can cause issues.
- Shortening the directory name can avoid issues where the installation path exceeds the Windows limitations for path length.
