Requirements for Binary Coexistence of the Siebel Web Server Extension

If you do not require side-by-side installations of the same or different versions of SWSE on the same computer, then uninstall any existing version of SWSE on the computer before installing the current version. See Uninstalling the Siebel Web Server Extension.

This topic is part of Requirements for Installing and Configuring the Siebel Web Server Extension.

Side-by-side installations of the same or different versions of SWSE on the same computer (sometimes referred to as binary coexistence) might be helpful in some upgrade scenarios or for development or testing purposes. In general, however, it is recommended that you install only one instance of SWSE on each Web server computer. Binary coexistence scenarios might be subject to limitations for your operating system and Web server platform.

For more information about creating and applying the SWSE logical profile, see Process of Configuring the Siebel Web Server Extension.

NOTE:  Scalability and performance implications must be taken into consideration when running multiple instances of SWSE on a single Web server computer.

Note the following considerations and limitations applicable to binary coexistence:

• Oracle Solaris using Oracle iPlanet Web Server. You can install multiple instances (virtual server instances) of Oracle iPlanet Web Server on the same computer. You can also install multiple instances of SWSE to run against these virtual server instances. Configure each SWSE instance to communicate with a separate virtual server instance using a different port.
• UNIX operating systems (including Linux) using Apache-based Web server. You can install multiple instances of a supported Apache-based Web server on the same computer. You can also install multiple instances of SWSE to run against these Web server instances. Configure each SWSE instance to communicate with a separate Web server instance using a different port.
• Microsoft Windows using Microsoft IIS. You can install only a single instance of the Web server on the same computer. You can install multiple instances of SWSE on this computer, but you cannot run multiple instances of SWSE simultaneously, unless you configure them to run in separate memory spaces.

  Before you configure a new installed instance of SWSE where another instance is already installed and configured, you must edit the batch file that creates the virtual directories for Siebel Business Applications so that the virtual directory names for the new instance are unique. The virtual directories are created by batch files in the SWSE logical profile directory. You can also edit these batch files before configuring the SWSE to remove entries for virtual directories that you do not need.
