Using Transaction Scope in Oracle

Question

Following is my code to call a transaction using .NET transaction scope:
using (TransactionScope sc = new TransactionScope())
try
OracleConnection c = new OracleConnection(ConfigurationManager.ConnectionStrings["oConn"].ConnectionString);
c.Open();
OracleCommand oc = c.CreateCommand();
oc.CommandText = "delete from test where issue_id=:issue_id";
oc.Parameters.Add("issue_id", OracleDbType.Int32).Value = 64;
var rowdelete = oc.ExecuteNonQuery();
c.Close();
OracleConnection c2 = new OracleConnection(ConfigurationManager.ConnectionStrings["oConn"].ConnectionString);
c2.Open();
OracleCommand oc2 = c2.CreateCommand();
oc2.CommandText = "delete from issue_no where issue_id=:issue_id";
oc2.Parameters.Add("issue_id", OracleDbType.Int32).Value = 64;
rowdelete = oc2.ExecuteNonQuery();
c2.Close();
sc.Complete();
catch (Exception ex)
throw ex;
It always throws exception: Data provider internal error(-3000)
It works fine when I remove transactions, what will be the cause for this? I cannot find related information about this error.

What version of ODP are you using? Does the behavior occur on current versions?
What is your connection string. That is to say, what format is it? I recall a known issue where using a fully qualified alias ( (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=...etc...) caused issues. Using a tnsnames.ora , or the instant client connect string (//host:port/service_name) did not have the problem.
