Sporadic connect failures to Oracle

Tech-Archive recommends: Fix windows errors by optimizing your registry

I thought I knew how to do this. But one, low-use web form occasionally loses form submissions and I haven't been able to understand why. I can't even duplicate the behavior.

The form's processor is in a JSCRIPT "class" so I'll pull out the relevant bits below.

Several users report seeing the "cannot save" message "thrown" when the test for this.aConnection.State!=1 fails.

No other place in the application presents that error, so I'd guess that's the problem: either the test itself is invalid, or we're really having trouble making connections.

Hints would sure be appreciated.

this.aConnection=null;

var sConnect="Provider=OraOLEDB.Oracle;Data Source=<>;User Id=<>;Password=<>";

this.aConnection=Server.CreateObject( "ADODB.Connection" );
if( !this.aConnection )
throw "The application cannot access information.";

this.aConnection.Open( sConnect );
if( this.aConnection.State!=1 )
throw "The application cannot save your submission.";

this.aConnection.Execute( <insert DDL to add a record>, 0, 1 );

this.aConnection.Close();
.
