ERROR [08001] [Sybase][ODBC Driver][SQL Anywhere]Specified database file already in use

[shouri....@gmail.com]

Hello everybody iam new to .NET and sybase so i need some help on
solving the issue.My project is to make web app compatible with vista
and windows 7.I have a delphi desktop application running and is
connected to Sybase SQL Anywhere 11 database now iam working on
developing .NET web application which uses a webservice to connect to
same database .I am not trying to open a new connection rather trying
to use
(share) the same connection to database opened by delphi desktop
application.When i tried using the webservice to connect to database i
got an error in the browser which is as follows:

ERROR [08001] [Sybase][ODBC Driver][SQL Anywhere]Specified database
file already in use

Connection String := ("Dsn=GlobeRelay5;uid=DBA;pwd=SQL")

Is there anyway i can share the same connection opened by
Desktop application ?.

I even tried opening a new connection which returned same
error
Here is the code

ODBC Connection Code:
using (OdbcConnection cn = new
OdbcConnection("Dsn=GlobeRelay5;uid=DBA;pwd=SQL"))
{
cn.Open();
const string domainString = "SELECT MailDomainName FROM
DBA.SETTINGS";
using (OdbcCommand cmd = new OdbcCommand(domainString,cn))
{
using (OdbcDataReader reader =cmd.ExecuteReader())
{
if (reader.HasRows)
{
while (reader.Read())
{
Settings.MailDomainName =
reader.GetString(0);
}
}

int fCount = reader.FieldCount;
}
}
}

How can i create a new connection to a database which is
already opened by other app whithout shutting down?.

Thank you

When using a DSN it tells the driver manager or library where to look
in the registry or sys info file to get the data source info. The
driver manager and driver get the rest of the connection parameters
from there. My guess is there is some parameter there that says to
start the database, but it's already started so it errors out. I'd
check those parameters.

As for sharing it's very possible, but I think only one thread should
be using a connection at a time. We have a pool that we manage
between our threads.
