mysql> SHOW STATUS LIKE 'Table%'; +-----------------------+---------+ | Variable_name | Value | +-----------------------+---------+ | Table_locks_immediate | 1151552 | | Table_locks_waited | 15324 | +-----------------------+---------+ Table_locks_immediate is the number of times that a table lock was acquired immediately, and Table_locks_waited is the number of times a table lock could not be acquired immediately and a wait was needed. If the Table_locks_waited value is high, and you are having performance problems, you may want to split up large tables; for example, you might create a dedicated cache table for a custom module or consider ways to reduce the sizes or the frequency of the table lock commands. One way to reduce table sizes for some tables, such as the cache_*, watchdog, and accesslog tables, is by reducing the lifetime of the data. This can be done within the Drupal administrative interface. Also, making sure cron is being run as often as once an hour will keep these tables pruned. Because Drupal can be used in many different ways, it is impossible to give an across-the-board recommendation as to which tables should use which engine. However, in general, good candidates for conversion to InnoDB are the cache, watchdog, sessions, and accesslog tables. Fortunately, the conversion to InnoDB is very simple: ALTER TABLE accesslog TYPE='InnoDB'; Of course, this conversion should be done when the site is offline and your data has been backed up, and you should be informed about the different characteristics of InnoDB tables.

When your expression must process the parameters using multiple lines of code, you can do so by denoting a scope for these statements using the expected curly brackets. Consider the following example update to our LambdaExpressionSyntax() method: static void LambdaExpressionSyntax() { // Make a list of integers. List<int> list = new List<int>(); list.AddRange(new int[] { 20, 1, 4, 8, 9, 44 }); // Now process each argument within a group of // code statements. List<int> evenNumbers = list.FindAll((i) => { Console.WriteLine("value of i is currently: {0}", i); bool isEven = ((i % 2) == 0); return isEven; }); Console.WriteLine("Here are your even numbers:"); foreach (int evenNumber in evenNumbers) { Console.Write("{0}\t", evenNumber); } Console.WriteLine(); } In this case, our parameter list (again, a single integer named i) is being processed by a set of code statements. Beyond the calls to Console.WriteLine(), our modulo statement has been broken into two code statements for increased readability. Assuming each of the methods we ve looked at in this section are called from within Main(): static void Main(string[] args) { Console.WriteLine("***** Fun with Lambdas *****\n"); TraditionalDelegateSyntax(); AnonymousMethodSyntax(); Console.WriteLine(); LambdaExpressionSyntax(); Console.ReadLine(); } we will find the following output: ***** Fun with Lambdas ***** Here are your even numbers: 20 4 8 44 Here are your even numbers: 20 4 8 44 asp.net upc-a UPC-A Barcode Generator for ASP .

How to optimize a web server. How to optimize a database. Drupal-specific optimizations. Possible multiserver architectures. The lambda expressions you have seen here processed a single parameter. This is not a requirement, however, as a lambda expression may process multiple arguments or none. To illustrate the first scenario, create a Console Application named LambdaExpressionsMultipleParams. Next, assume the following incarnation of the SimpleMath type: public class SimpleMath { public delegate void MathMessage(string msg, int result); private MathMessage mmDelegate; public void SetMathHandler(MathMessage target) {mmDelegate = target; } public void Add(int x, int y) { if (mmDelegate != null) mmDelegate.Invoke("Adding has completed!", x + y); } } Notice that the MathMessage delegate is expecting two parameters. To represent them as a lambda expression, our Main() method might be written as follows: static void Main(string[] args) { // Register w/ delegate as a lambda expression. SimpleMath m = new SimpleMath(); m.SetMathHandler((msg, result) => {Console.WriteLine("Message: {0}, Result: {1}", msg, result);}); // This will execute the lambda expression. m.Add(10, 10); Console.ReadLine(); } Here, we are leveraging type inference, as our two parameters have not been strongly typed for simplicity. However, we could call SetMathHandler() as follows: m.SetMathHandler((string msg, int result) => {Console.WriteLine("Message: {0}, Result: {1}", msg, result);}); Finally, if you are using a lambda expression to interact with a delegate taking no parameters at all, you may do so by supplying a pair of empty parentheses as the parameter. Thus, assuming you have defined the following delegate type: public delegate string VerySimpleDelegate(); you could handle the result of the invocation as follows: // Prints "Enjoy your string!" to the console. VerySimpleDelegate d = new VerySimpleDelegate( () => {return "Enjoy your string!";} ); Console.WriteLine(d.Invoke());
