У меня есть приложение в asp.net 3.5, а база данных - сервер Sql 2005.
"Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached."
Некоторое время эта ошибка возникла. Как решить эту ошибку.
Я пытаюсь SqlConnection.ClearAllPools();, но это тоже не работает.
SqlCommand cmdToExecute = new SqlCommand();
cmdToExecute.CommandText = "dbo.[sp_user_listing]";
cmdToExecute.CommandType = CommandType.StoredProcedure;
DataTable toReturn = new DataTable("courier_user_listing");
SqlDataAdapter adapter = new SqlDataAdapter(cmdToExecute);
// Use base class' connection object
cmdToExecute.Connection = sqMainConnection;
try
{
cmdToExecute.Parameters.Add(new SqlParameter("@suser_name", SqlDbType.VarChar, 250, ParameterDirection.Input, true, 0, 0, "", DataRowVersion.Proposed, _user_name));
if (blnMainConnectionIsCreatedLocal)
{
// Open connection.
sqMainConnection.Open();
}
else
{
if (CPMainConnectionProvider.IsTransactionPending)
{
cmdToExecute.Transaction = CPMainConnectionProvider.CurrentTransaction;
}
}
// Execute query.
adapter.Fill(toReturn);
i32ErrorCode = (Int32)cmdToExecute.Parameters["@iErrorCode"].Value;
if (i32ErrorCode != (int)LLBLError.AllOk)
{
// Throw error.
throw new Exception("Stored Procedure 'sp_courier_user_SelectAll' reported the ErrorCode: " + i32ErrorCode);
}
return toReturn;
}
catch (Exception ex)
{
// some error occured. Bubble it to caller and encapsulate Exception object
throw new Exception("Courier_user::SelectAll::Error occured.", ex);
}
finally
{
if (blnMainConnectionIsCreatedLocal)
{
// Close connection.
sqMainConnection.Close();
}
cmdToExecute.Dispose();
adapter.Dispose();
}
