Updater then creates two update SQL scripts - one for the Learning Management System server (updateLMM.sql)
and one for the Delivery Server (updateDS.sql). These scripts are then run to change the respective databases.
You can change settings through the user interface at any time. Since virtually all required application settings can
be specified through the Installer or the user interface, it is unlikely that you would ever need to modify the XML
files.
Finally, some Learning Management System application settings come from the WebSphere application server itself.
The Learning Management System application is packaged containing references to Objects that are retrieved from
the application server environment at runtime. For example, the Learning Management System uses JDBC
datasources it retrieves from the environment via JNDI. By changing the definition of the datasource in the
WebSphere console, you can change the database that the Learning Management System connects to without
modifying the Learning Management System directly.
An outline of the installation process
The following steps outline the Learning Management System installation/deployment process. They should be
followed in this order to avoid version skew among the various components to be installed:
1. Identify hardware assets
The Learning Management System can be installed on various types and configurations of servers. The
expected capacity of the installation is the key factor in determining the requirements for servers. The install
process described in this document assumes that the desired server or servers have been identified and
configured such that required products can be installed.
For more information, refer to “Chapter 4 Identifying Learning Management System Hardware Assets.”
Refer also to your WebSphere documentation for guidelines on the various server configuration options that
are available for your Learning Management System deployment.
2. Install the database server software
The Learning Management System runs against the following back-end relational databases:
• DB2®
• Oracle®
• SQL Server™
You must install one or another of these before you install the Learning Management System software.
3. Install WebSphere core
You are required to have the WAS (WebSphere Application Server) Core installed on the desired systems.
This can be a single server or multiple servers. If multiple servers are used, you must also install the
Network Deployment module. The WebSphere Core installation is accomplished by using the GUI installer
that is standard with WAS.
For more information, refer to “Chapter 5 Installing the WebSphere Core.”
4. Install or identify the LDAP Directory
The Learning Management System requires an LDAP directory for product operation. Either an IBM
Directory Server™ 4.1 directory is installed or configured, or a pre-existing LDAP directory must be
identified. Also, at least two user names that are recorded in the directory must be identified. These are for
