this will help The timeout will only limit the max possible you'll wait. It won't make quick things take longer.
Sometimes there is nothing you can do, and a feature is just ridiculous, and will take a ridiculously long time. In this case, a longer timeout is just necessary.

it helps some times Check that the Transaction and Connection timeouts are set with more than 30 seconds...
Hope this can helps,

How can we set the CommandTimeout as a property in our class and when set it will take effect all in DAL

Hope this helps You can create a method from where SqlCommand object will be returned and you can use it in every method so every command will have timeout 60;
public SqlCommand GetCommandObj()
{
        SqlCommand cmd=new SqlCommand();
        cmd.CommandTimeout=60;
        cmd.CommandText="your query here";
        return cmd;
}

Setting CommandTimeout to solve lock wait timeout exceeded try restarting transaction


Tag : chash , By : Diego

seems to work fine I was receiving "lock wait timeout exceeded try restarting transaction" intermittently. Then I started wrapping everything in transactions and I stopped receiving those errors. This should prevent table locks from remaining after the query is executed.
(Assuming "conn" is a MySqlConnection, "iLevel" is the isolation level you want to use, and "query" contains your query as a string)
int rowCount = 0; // In case you want the number of rows affected

try
{
    if (conn.State != ConnectionState.Open)
        conn.Open();

    MySqlCommand command = new MySqlCommand(query, conn);   

    using(var transaction = conn.BeginTransaction(iLevel))
    {   
        command.Transaction = transaction;                 
        command.CommandTimeout = int.MaxValue;

        // Set parameters etc...

        try
        {
            rowCount = command.ExecuteNonQuery();
            transaction.Commit();
        }
        catch(Exception ex)
        {
            transaction.Rollback();         
            // Handle query exception...            
        }
    }
}
catch(Exception ex)
{
    // Handle general exception...
}

What is the effect of setting a linux socket - high priority?


Tag : linux , By : Steve M

will help you Every Linux network interface has a so called qdisc (queuing discipline) attached to it. And the answer to your questions depends on the qdisc in use. Some queuing disciplines like pfifo and bfifo, have no concept of priority. So if they're used, the answer is simple - there will be no prioritization
However, with a prioritizing qdisc such as pfifo_fast (which typically the default qdisc on Linux), the socket priority can have an effect.
