18.3.2. Testing the Virtuoso Mono Runtime Environment
To test that you have successfully started the Virtuoso server with Mono CLR runtime support make a simple library, import the contained class into Virtuoso and call it.
Using an text editor create a C# source file in the server root directory called sanity.cs, with the following contents:
using System; public class sanity { public static string test(string name) { return "Hello "+ name + ", from Virtuoso"; } }
This sample needs to be compiled into bytecode assembly before it can be used. Make sure you environment is configured to use Mono, change directory to the Virtuoso server root containing the C# source file. Run:
bash$ mcs /target:library sanity.cs Compilation succeeded
Now this library must be introduce to the Virtuoso Server. Using ISQL use the following commands to test the CLR:
C:\Program Files\OpenLink\Virtuoso 3.0\bin>isql 1112 Connected to OpenLink Virtuoso Driver: 03.00.2315 OpenLink Virtuoso ODBC Driver OpenLink Interactive SQL (Virtuoso), version 0.9849b. Type HELP; for help and EXIT; to exit. SQL> DB..import_clr (vector ('sanity'), vector ('sanity')); Done. -- 300 msec. SQL> select sanity::test('Rob'); callret VARCHAR ______________________________________________ Hello Rob, from Virtuoso 1 Rows. -- 60 msec.
Congratulations, you have proven that your Virtuoso server can run .NET classes via Mono Runtime.
