About the Siebel Database Server

Upgrades: All upgrades.

Environments: All environments.

The executables for doing an upgrade reside on the Siebel Server. You can use any upgraded Siebel Server to perform an upgrade of the Siebel Database.

The Siebel Database Server is not a server in the sense that it participates in processing business data like a Web server or Siebel Server. Instead, the Siebel Database Server is a set of files and scripts that provide inputs to the upgrade executables.

For best performance, install the Siebel Database Server files on the Siebel Server that you will use to perform the upgrade. You must manually select the Siebel Database Server for installation; it is not automatically installed when you install a Siebel Server.

The Siebel Database Server files will be installed at the same directory level as the Siebel Server in a directory called dbsrvr. For example, if the Siebel Server is installed in C:\sea7xx\siebsrvr (Windows), then the Siebel Database Server will be installed in C:\sea7xx\dbsrvr. You need to install only one Siebel Database Server.

To edit and execute Siebel Database Server procedures and maintenance scripts, you must have READ-WRITE access to the Siebel Server bin directories in SIEBEL_ROOT (Windows), $SIEBEL_ROOT (UNIX). You must also have READ-WRITE access to the Siebel Server Log directories and upgrade directory.
