Large Deployments

This topic is part of Determining Your Installation and Configuration Method.

Do you require a relatively large deployment? Will you use multiple servers to deploy your Siebel Enterprise Server components? Siebel Enterprise Server components include Siebel Gateway Name Server, Siebel Server, and Database Configuration Utilities.

If you must support many users or multiple Siebel applications and have multiple servers available, you will probably install the Siebel Gateway Name Server on a different machine than the Siebel Server.

A large deployment usually requires multiple Siebel Servers running on different machines. Each Siebel Server may be configured to run a particular application or set of applications. Or, multiple Siebel Servers may be part of a pool of similarly configured servers participating in load balancing. Install and configure one Siebel Server first, then add Siebel Servers after completing the remaining installation and configuration tasks.

Use the Siebel Enterprise Server installer (after you have created the Siebel Database instance) to install the Enterprise Server components.

You install the Database Configuration Utilities with one of the Siebel Servers. The Siebel Database itself is located on a different machine than the Siebel Enterprise Server software.

You can install in GUI or console mode, or use unattended installation.

After GUI installation, the Configuration Wizard launches automatically so you can configure all Siebel Enterprise Server components. Optionally, you can cancel configuration and perform Configuration Wizard tasks later. In this case, first configure the Siebel Gateway Name Server, then the Siebel Enterprise, then the SWSE logical profile.

NOTE:  If you are installing in console mode, you must modify the siebel.ini file to prevent the Configuration Wizard from launching after installation. Launch the Configuration Wizard manually after installing. See also Editing siebel.ini Files for Console Mode Installation.

After installing and configuring the Siebel Enterprise Server components, you configure the Siebel Database.

You install and configure the SWSE on the Web server machine, which includes applying the SWSE logical profile.

Options that can help you install and configure Siebel software efficiently include:

• As an alternative to GUI or console mode installation, you may prefer to perform unattended installation. For more information, see Installing and Configuring in Unattended and Console Modes.
• You may want to separate installation and configuration tasks. After basic deployment decisions are made, installations can be done under the supervision of administrators who are most familiar with Siebel Business Applications. Such specialized administrators may perform all Siebel Configuration Wizards tasks.
• You can perform offline configuration, which can save you time, provide greater flexibility, and reduce error, compared to manually configuring each installed component separately. Offline configuration prepares a response file for running the Configuration Wizard in execute mode (unattended configuration). Any installation mode can be configured to automatically launch unattended configuration.
