Upgrading the Servers on Supported UNIX Platforms

---

Refer to your previously completed copy of the Upgrade Planning Worksheet for server names and other installation information.

To stop all servers

1. Stop all Siebel Servers by typing: stop_server all
2. Stop the Siebel Gateway by typing: stop_ns

To uninstall the earlier version of the Siebel Servers

1. If you wish to preserve your installation-specific Siebel Server configuration parameters, record your current configuration.

   You will need to reapply that configuration manually after completing the upgrade. Installation-specific parameters will be lost when you uninstall your existing Siebel Servers. When you install the new Siebel Server Release 7.x software, you can reset these parameters manually through the Server Manager.

2. Uninstall the previous version of the Siebel Server software by deleting the $SIEBEL_ROOT directory for the previous version.

   NOTE:  To avoid conflicts with the ODBC drivers used by the new Siebel Server software, remove any older versions of the ODBC drivers. If the vendor provided an uninstall option, use it. If the vendor has not provided an uninstall option, contact the vendor for removal instructions.

To uninstall the earlier version of the Siebel Gateway

• Uninstall the Siebel Gateway by deleting your previous installation directory.

  NOTE:  If you wish to preserve your previous configuration parameters (for example, if you set MaxTasks, MaxServer, MinServers to specific values) you need to save your previous configuration. Then, after the upgrade, use srvrmgr to reset your configuration parameters. This applies to all parameters that have been changed from the standard installation.

To install the version 7.5 Siebel Gateway

• Refer to the appropriate chapter on installing the Siebel Gateway in Siebel Server Installation Guide for the operating system you are using.

To install the version 7.5 Siebel Servers

1. Make sure that each application server on which a Siebel Server will be installed has the correct versions of all required third-party software products, as documented in Siebel System Requirements and Supported Platforms.
2. Install the new Siebel Server on all application servers as described in Siebel Server Installation Guide for the operating system you are using.

   NOTE:  With the Siebel Enterprise Server (SES) installer, when the Siebel Server is chosen, make sure that you choose the Siebel Database Server as well.
