use CGI;
use DBI;

# Connect to database.

my $My_dbh =
DBI->connect("DBI:Sybase:myserver","myuser","mypassword",{'RaiseError' =>
1});

**************************************

I get following Error(s):

The context allocation routine failed.

the following problem casued the failure:

Invalide context version.
