Chapter 4 Configuring Web Servers and Web sites

Configuring a Dynamo Web site

If you have a live Internet connection you do not need to use the Personal Web Server to access Dynamo Web content on a Web site. Use one of the application servers (or gateways) provided as part of PowerDynamo to serve Dynamo Web site content to the site Web server.

PowerDynamo includes an Application Server for each of these interfaces:

CGI For integration with CGI-compatible Web servers.
WIN-CGI For integration with Windows CGI-compatible Web servers.
ISAPI For integration with Microsoft Internet Information Server or other ISAPI Web server.
NSAPI For integration with a Netscape Web server or other NSAPI Web server.

Configuring Web servers during installation

If you have a Web server installed on your machine, the installation program allows you to configure the server to work with PowerDynamo. The installation program adds the appropriate DLLs to your system path, and installs the PowerDynamo Application Server software on the Web server machine. However, you must still create a connection profile and configure the application server for PowerDynamo to work properly.

If you install a Web server after installing PowerDynamo, you can use the setup -webserver command to reexecute the installation program.

Configuring Web Servers manually

The following procedure is an overview of the steps required to configure a Dynamo Web site. Detailed instructions specific to each of the supported server interfaces follow.

Ensure that PowerDynamo has been installed on the Web server machine before beginning configuration. For future administration use, Sybase recommends that all PowerDynamo components remain installed on the Web server machine. You must confirm that you are properly licensed to use PowerDynamo and Adaptive Server Anywhere or Adaptive Server Enterprise on your Web site before you can configure your Web site.

To configure a Dynamo Web site:

Edit your computer's path to include the Application Server DLLs. If the Web server was configured during the PowerDynamo installation, this step is not necessary.
Install the PowerDynamo Application Server software on the Web Server machine, if it is not already.
For database-based Web sites, create an ODBC System Data Source Name (DSN). If you are using an Open Client connection, this step is not necessary.
For database-based Web sites, create a Sybase Central connection profile.
Configure the Application Server by defining mappings from a URL to a Dynamo site.

When you install a new version of PowerDynamo, preexisting Web sites may no longer work. If this is the case, you are notified the first time you attempt to connect to a site from Sybase Central. If a Web site does not need to be upgraded, you can connect to the site in the regular fashion.

Do not start the Web server until after you have connected to your preexisting Web site and upgraded it to the new version.

You should always connect to a Web site with the same type of connection that was used for the original creation of the site. For example, if you created the sample Web site with an ODBC connection, do not later attempt to connect to it with an Open Client connection.
