"The computer is not authorized, please go to the store-authorize this computer," the problem is because the root node appears because of multiple Apple accounts, we look at how to solve.
As a first step, we click on "Set up-itunes store and App Store" on iOS devices to see which account is already logged in.
The second step is to connect your iOS devices, such as the IPhone, to the computer via a data cable
The third step is to select the "file-device-Buy from XXX" program on the computer
Almost every application in the integration of UC will be unable to synchronize the login synchronization exit situation, the reason for today's analysis
First of all, our project will uc_client this folder intact copy to the project root directory,
Public Function Intelogin ($loginname, $password) {$this->_INITUC ();if (true = = = $this->uc_integration) {if (true = = = Xvalid::isemail ($loginname)) {$logintype = 2;}else {$logintype = 0;}if (uc_charset! = Oesoft_charset) {$uc _loginname = XHANDL
The first step, we open the Assistant, and then click on the interface in the upper-right corner of "Three horizontal" select "Address Book collation" details as shown in the following figure.
The second step, and then in the open Address Book, we find inside the "empty Address Book", click "Empty the entire computer contact", click "completely delete" on it.
The third step, OK now we are in the QQ assistant these people deleted.
Haha, QQ

Mysql5.5 semi-sync replication installation and maintenance
MySQL's replication protocol is asynchronous. Although asynchronous efficiency and performance are good, it cannot guarantee master-slave data consistency (if the master crash, transactions that have been committed will not be transferred to any slave.) from mysql5.5, MySQL introduces the semi-sync function to ensure d
The Sync Framework is a full-featured synchronization platform that enables collaboration and offline access to applications, services, and devices. The Sync Framework provides some technologies and tools to support roaming, sharing, and fetching data while offline. By using the sync Framework, developers can build synchronous ecosystems that integrate arbitrary

This is the case of a customer in February March. The reason is that after the server hardware is replaced, the Business Translation occasionally experiences slow submission. Let's take a look at AWR.
We can see that the load profile information of the system is actually not high, only 21 transactions per second. Let's take a look at top5events:
From the top 5 events, we can find that the AVG wait of Log File sync is very high, as high as 124 Ms.
First, IntroductionPt-table-checksum is one of the Percona-toolkit series tools that can be used to detect the consistency of the data in the master and from the database. The principle is to run on the Main library, checksum the synchronized tables and record them. It then compares the checksum of the main table to determine whether the data is consistent . The detection process in blocks, for large tables can be differentiated into multiple blocks, so as to avoid the lock table (according to a

Use pt-table-sync to restore inconsistent data
In the previous article, pt-table-checksum was used to verify data consistency. This section describes how to verify master-slave data consistency. when determining whether master-slave data is inconsistent, you must consider how to fix it. We recommend another important tool of percona-toolkit: pt-table-sync.

The Svnsync can easily synchronize another source SVN version to the specified repository, providing convenience for multi-version library applications.Example: (The repository is stored under directory/svn/)Source Version library: svn://196.168.0.1/testa Sync User:sync_source Password:123456Target repository: svn://196.168.0.2/testb Sync User:sync Password:123456The source repository is used to develop app
In Java, the Synchronized keyword is used to control thread synchronization, that is, in a multithreaded environment, control synchronized code snippets are not executed concurrently by multiple threads. Synchronized can either be added to a piece of code or added to a method.The point is, don't think it's all right to add synchronized to a method or snippet, and look at the following code:Class Sync {public synchronized void Test () {System.out.print
