Planning the Siebel Directory Structure

You must plan where to install the various Siebel components on your servers. Also plan how to install multiple versions, if your organization requires multiple versions for testing purposes.

Installing Multiple Versions of Siebel eBusiness Applications

Multiple versions of Siebel components may, in some cases, be installed on the same machine.

• Multiple versions of the Siebel Gateway Name Server must be installed on separate machines.
• If you install multiple versions of the Siebel Server on the same machine, you must install them in different directories. Each Siebel Server must be assigned to a different Enterprise.
• If you install multiple versions of the Siebel Web Server Extension (SWSE) on the same machine, you must install them in different directories. Additional configuration steps are required.

For more information about configuring SWSE, see Technical Note 456 on Siebel SupportWeb.

You should use a naming convention that reflects the components and the version number being installed.

Installing Multiple Components of the Same Version of Siebel eBusiness Applications

The installer wizard automatically installs each server, or other component of a Siebel Enterprise Server, on a single computer in a unique directory that will not conflict with other software components of the same version. If other versions of the Siebel component you are installing exist on that machine, custom locations may need to be chosen.

You do not need to specify a different directory path for the Siebel Database Server and Siebel Server when installing these two on the same machine.

You can only install Siebel Enterprise Server (SES) components, Siebel Gateway Name Server, Siebel Server, Siebel Database Server, and EAI connectors in the same root directory. When installing multiple products into the same root directory, be sure that all products match the same release and patch level.

CAUTION:  Although you cannot install additional products into a root directory after applying a patch, you can install additional languages into a root directory. However, you must reapply the patch after you install additional languages.

Installing Siebel CORBA Object Manager

Consider installing the Siebel CORBA Object Manager component on a dedicated machine. The Siebel CORBA Object Manager can be installed on a machine that also supports the Siebel Enterprise Server components. However, for best performance, you should install the Siebel CORBA Object Manager onto a dedicated machine.

NOTE:  Both the Siebel CORBA Object Manager and the Application Object Manager (a component of the Siebel Server) use configuration files located in SIEBEL_ROOT\bin. If you install the Siebel CORBA Object Manager in a SIEBEL_ROOT directory also used by the Siebel Server, be sure that you create uniquely named configuration files for the two types of Object Manager if their configurations differ. For information about how to register a configuration file with the appropriate component, see Siebel System Administration Guide.
