About the Environment Verification Tool (EVT)

The Environment Verification Tool (EVT) is a tool intended to help system administrators verify the configuration of the Siebel Business Applications environment. System administrators can use the EVT utility to identify errors and potential problems in the Siebel Enterprise after installation in a development or test environment, or following rollout or upgrades.

It is recommended to use EVT to verify your Siebel applications environment.

The EVT utility is included with the installed software for Siebel Server, Siebel Gateway Name Server, and Siebel Web Server Extension (SWSE). It is provided for each supported Siebel Enterprise Server platform.

EVT uses various operating systems utilities and Siebel command-line utilities to query information about Siebel components' installation and configuration settings.

EVT verifies that the machines running Siebel software are configured correctly and according to Siebel System Requirements and Supported Platforms on Oracle Technology Network.

What Products Can EVT Check?

You can run EVT against Siebel Business Applications modules and some third-party products.

• Siebel Gateway Name Server
• Siebel Server
• Siebel Web Server Extension
• Web server (Microsoft IIS, IBM HTTP Server, HP Apache Web Server, Oracle HTTP Server, or Oracle iPlanet Web Server)
• Database

EVT Check Groups

The EVT engine is driven by a configuration file (evt.ini). This file is specific for each version of the Siebel Business Applications, and cannot be used to run the utility against an earlier or a later version of the software. This file identifies the default checks that need to be run, and also provides the dependency logic, such as operating system-specific checks or database-specific checks, between different checks. The evt.ini file can be customized to check for other issues as well.

If you want to create customized checks, create a copy of the original evt.ini file for this purpose, so that you do not accidentally affect EVT functionality.

You can use EVT to validate configuration settings in the following check groups:

• Environment checks (ENV)
• Siebel Server checks (SVR)
• Database client checks (DBC)
• Web server checks (WEB)
• Database server (RDBMS) checks (DBS)
• Internal checks (INT)
• Network settings checks (NET)
• Operating settings checks (OS)
• Other checks (OTH)
