2.2.Virtuoso for Windows Home 2.2.2.Getting To Know Your Virtuoso Components

2.2.1.Before You Start

To ensure a smooth installation, please review the following checklist before you start the setup program.

Have you downloaded the software?

If you have not already done so, please download your copy of OpenLink Virtuoso from the OpenLink web site. The URL is http://www.openlinksw.com . When you visit the site, select "Download & Evaluation".

  1. Select product "OpenLink Virtuoso: Personal Edition "

  2. From "Product Category" choose "Universal Server"

  3. From "Product" choose "Virtuoso Universal Server"

  4. Select "Database Version"

  5. From "server OS" select "Windows" and click "Next"

  6. Select a release and click "Next"

  7. You will be prompt to login in not already.

  8. Click "Next"

  9. Download the desired component. For example, click the HTTP link for "Multi-Threaded Universal Server (Commercial Edition) for OpenLink Virtuoso 4.x"

Do you have the License file?

The server will need a license file, and this is automatically delivered by email as part of the download process. It is therefore important to supply a valid email address. The installer will prompt for the license file location.

Reinstalling Virtuoso?

If you are reinstalling Virtuoso, you must first shutdown any additional database servers you have configured on non default ports. The databases on port 1111 and 1112 will automatically be stopped during the install process. On Windows NT/2000/XP, go to the services applet in the Control Panel. There you can stop services that appear with names of the form "OpenLink Virtuoso DBMS Server [instance name]".

On Windows NT/2000/XP you can also shut them down with the following commands in the Virtuoso\bin directory:

virtuoso-odbc-t.exe +service stop
virtuoso-odbc-t.exe +instance myinstance +service stop
virtuoso-odbc-t.exe +instance anotherinstance +service stop
[Note] Note:

There is an alternative executable available for Virtuoso called: virtuoso-odbc-f.exe, which you may have installed. This version is designed for versions of Windows that offer no native threading support such as Windows 98, and offers no advantages over virtuoso-odbc-t.exe for Windows NT/2000/XP.

You can list the services with their status using:

virtuoso +service list

Allocation of TCP/IP ports

The Default database have the following port allocations:

Table2.2.Port Usage

Port Used by
1111 Default Virtuoso Server port
8889 Default Virtuoso Visual Server Administration Interface HTTP port

By default, the Virtuoso DBMS listens on port 1111. This port number is not selectable at install time. If the port is currently in use by another server then after the installation completes you will need to change the port number in the Local Virtuoso ODBC DSN that is created during the installation process, and also in the following file:

C:\Program Files\OpenLink Software\Virtuoso 5.0\bin\virtuoso.ini

To check if a port is in use on NT, you can use the following command, and review the output:

netstat -an | more

Do you already have an ODBC Data Source Name (DSN) that works?

The Virtual Database aspects of the Virtuoso for ODBC assumes that you already have an ODBC driver on your machine from a database vendor, OpenLink Software, or from another 3rd party vendor. It is a useful sanity-check to ensure that you have an ODBC System Data Source Name (DSN) on your machine, and that it successfully connects to your database, and that it retrieve data. Any ODBC compliant tool can be used to test that your ODBC Data Source Name (DSN) works, such as the sample application we provide - C++ Demo32, and that it is sufficiently robust to operate with Virtuoso. Virtuoso is ODBC Driver Independent and certified to work with any drivers that are ODBC level 1 or higher.
