The corporate library problem

Are we using Enterprise Library 6.0 and the following code to create a database instance and execute a stored procedure? Any help is greatly appreciated. Thanks in Advance.

 DatabaseProviderFactory factory = new DatabaseProviderFactory();
             Database  db = factory.CreateDefault();

 DbCommand dbCommand = db.GetStoredProcCommand("ProcedureName");

                OracleParameter outval = new OracleParameter("Test", OracleDbType.RefCursor);
                outval.Direction = ParameterDirection.Output;
                dbCommand.Parameters.Add(outval);

                using (IDataReader reader = db.ExecuteReader(dbCommand))
                {
                    while (reader.Read())
                    {

                    }
                }

<add name="providerConnString" connectionString="Data Source=ABCD;Password=testuser;User ID=testpwd" providerName="Oracle.DataAccess.Client" />

      

        
        
        
      

    

We get the following exception intermittently. This happens when we try to access the application after being idle. How does the pooling work in the corporate library? How will it work if the application is idle for a long time? What is the default minimum pool size and the default maximum pool size?
