public class Receiver { AutoResetEvent semaphore; public Receiver(AutoResetEvent theSemaphore) { semaphore = theSemaphore; } public void WaitForEvents() { while (true) { semaphore.WaitOne(); // this call blocks until semaphore is signaled // notification received... } } } The sender and receiver are assumed to run in different threads of the same process. The Sender and Receiver objects are given a reference to the shared semaphore. When Sender wishes to fire an event, it signals the semaphore by calling the Set method. The Receiver object calls the semaphore s WaitOne method to block and wait for incoming notifications. A problem with the example shown is that AutoResetEvent is a binary semaphore, so it only supports two states. If the semaphore is set before sender fires the event, it means there is a pending notification that the receiver hasn t read yet. The sender would need to wait until the receiver cleared the semaphore before firing a new event; otherwise, the receiver would miss the first notification. What you need is a regular semaphore that manages an internal counter that stores the number of pending notifications. The diagram in Figure 8-19 shows how the semaphore would be used. free download barcode scanner for java mobile Java Barcode API - DZone Java
27 Sep 2010 ... A common example of 2D bar code is QR code (shown on right) which is commonly used by mobile phone apps. You can read history and more info about Barcodes on Wikipedia.

Views have several benefits to offer, but faster performance may not necessarily be one of them. Views are useful when you want to present only the relevant portions of a table to an application or a user. Whenever you query a view, it has to be instantiated at that time. Because the view is just a SQL query, it has to perform this instantiation if you want to query the view again. If your query uses joins on views, it could lead to substantial time for executing the query. java barcode api open source Android Barcode Reader and Qr Code Scanner using Google ...

Barcode Scanner library for Java , Android with Zxing core. barcode barcode- scanner ... This is Android Qrcode & Barcode scan example using zxing library. Full table scans can occur sometimes, even when you have indexed a table. The use of functions on indexed columns is a good example for when you unwittingly can cause Oracle to skip indexes and go to a full table scan. You should avoid the use of inequality and the greater than or equal to predicates, as they may also bypass indexes. Figure 8-19. Using a regular semaphore to deliver notifications The difference between this diagram and the one using a binary semaphore is the semaphore method called when an event is fired. With a regular semaphore, you call the Signal operation to increment the semaphore s internal counter. Now the sender doesn t have to wait for the receiver to read notifications, and can fire events at will. Listing 8-21 and Listing 8-22 show an Object Pascal implementation. java barcode printing library Java barcode reader . How to create barcode scanner in Java ...

Performance tuning involves the optimization of SQL code and the calibration of the resources used by Oracle. The developers generally perform SQL tuning, and the DBA merely facilitates their tuning efforts by setting the relevant initialization parameters, turning tracing on, and so on. Nevertheless, the DBA can implement several strategies to help improve SQL processing in his or her database. In some cases, you and the developers might be working together to optimize the application. What if you can t modify the code, as is the case when you re dealing with packaged applications Alternatively, what if even the developers are aware that major code changes are needed to improve performance, but time and budget constraints make the immediate revamping of the application difficult There are several ways you can help without having to change the code itself. It s common for DBAs to bemoan the fact that the response times are slow because of poorly written SQL. I ve heard this in every place I ve worked, so I assume this is a universal complaint of DBAs who have to manage the consequences of bad code. A perfectly designed and coded application with all the right joins and smart indexing strategies would be nice, but more often than not, that perfect state of affairs doesn t happen. The theory of the next best option dictates that you should do everything you can to optimize within the limitations imposed by the application design. That said, let s look at some of the important ways in which you can help improve query performance in an application, even when you can t change the code right away. barbecue java barcode generator Java Code - 128 Generator , Generating Barcode Code 129 in Java ...
