By default, the Siebel installers automatically install Siebel software in unique directories that will not conflict with other Siebel software components, of the same or different versions, that you install on the same machine.
To install another instance of the same version of a product on a single machine, specify a custom installation path. However, you cannot install multiple instances of the same version of Siebel Gateway Name Server on the same machine.
NOTE: In this context, same version refers to all releases sharing the same first two digits—such as 7.8.1, 7.8.2, and so on. Each product instance of the same version would be installed to the same default installation path, unless you specify a custom path. A release can be installed as a maintenance release if the prior release of the same series is already installed. For example, if available, 7.8.3 could be installed as a maintenance release if 7.8.2 is already installed.
Subcomponents of the Siebel Enterprise Server that are installed on the same machine must be installed into the same root directory. The subcomponents are Siebel Gateway Name Server, Siebel Server, Siebel Database Server, and EAI connectors. See also File and Directory Naming Conventions.
NOTE: You cannot install additional subcomponents into a root directory after applying a patch. You can install additional languages into a root directory after applying a patch, but you must reapply the patch afterwards.
Multiple versions of Siebel components can be installed on the same machine. Sometimes you may need to do this as part of some upgrade scenarios. For more information about upgrading, see the Upgrade Guide.
