use Fcntl; flock DATA, LOCK_EX; print DATA $message; flock DATA, LOCK_UN;

Note that flock will block process execution until such time as the requested lock can be achieved The way to get around this is to use $LOCK_NB, which attempts to lock the filehandle without blocking However, caution should be used here: you must

SQL> alter system set local_listener='(address=(protocol=tcp)(host=127001)(port=1522))';

CHAPTER 38 DEEPER INTO C#

LOCK_SH LOCK_EX LOCK_UN LOCK_NB Table 7-10

This syntax is perfectly acceptable, but the use of a name that can be resolved is better practice, as it places a layer of abstraction between the logical name and the physical address The abstraction means that if the listening address ever has to be changed, one need only change it in the name resolution service, rather than having to change it in every instance that uses it

At the beginning of this chapter you saw that to establish a session against an instance, your user process must issue a connect string That string resolves to the address of a listener and the name of an instance or service In the discussion of dynamic instance registration, you saw again the use of a logical name for a listener, which needs to be resolved into a network address in order for an instance to find a listener with which to register Oracle provides four methods of name resolution: easy connect, local

make sure you test the result of the lock before you start using the file When using $LOCK_NB, the result from flock will be true, irrespective of whether the lock succeeded In nearly all cases file locking is generally advisory, that is, the fact the lock has been set does not guarantee that another application will not be able to access or overwrite the file This is because all applications that use the file need to use the same file locking mechanism This is especially true if the underlying implementation is through the flock() function because of the way in which flock() sets its locks You should also be aware that it is unlikely that flock will work over a networked file system If you want to force the use of fcntl, you will need to use it directly; so the equivalent of the earlier example becomes

use Fcntl qw/F_SETLK LOCK_EX LOCK_UN/; fcntl(DATA,&F_SETLK,LOCK_EX); print DATA $message; fcntl(DATA,&F_SETLK,LOCK_UN);

naming, directory naming, and external naming It is probably true to say that the majority of Oracle sites use local naming, but there is no question that directory naming is the best method for a large and complex installation

public delegate Point[] CloneFunction(Point[] a); public static void TimeFunction(Point[] arr, CloneFunction func, string label) { Point[] arrCopy = null; long start; long delta; double min = 5000.0d; // big number; // do the whole copy retryCount times, find fastest time for (int retry = 0; retry < retryCount; retry++) { start = Counter.Value; for (int iterate = 0; iterate < iterations; iterate++) arrCopy = func(arr); delta = Counter.Value - start; double result = (double) delta / Counter.Frequency; if (result < min) min = result; } Console.WriteLine("{0}: {1:F3} seconds", label, min); } public static void Main() { Console.WriteLine("Points, Iterations: {0} {1}", points, iterations); Point[] arr = new Point[points]; for (int index = 0; index < points; index++) arr[index] = new Point(3, 5); TimeFunction(arr, new CloneFunction(Point.ClonePointArrayMemcpy), "Memcpy"); TimeFunction(arr, new CloneFunction(Point.ClonePointArrayUnsafe), "Unsafe"); TimeFunction(arr, new CloneFunction(Point.ClonePointArray), "Baseline"); } } The timer function uses a delegate to describe the clone function, so it can use any of the clone functions. It uses a Counter class, which provides access to the system timers. The accuracy of this class will vary based upon the version of Windows that s being used. As with any benchmarking, the initial state of memory is important. To help control this, TimeFunction() executes each method five times and prints only the shortest time. Typically, the first iteration is slower; the CPU cache isn t ready yet, so subsequent times get faster. The times listed in Table 38-1 were generated on a 600MHz Pentium III laptop running Windows 2000
