Microsoft sync framework is a fully functional synchronization platform that implements applications.Program, Service and device collaboration and offline access. It provides some technologies and tools that support roaming, sharing, and obtaining data offline. By using the sync framework, developers can build a synchronization ecosystem to integrate any application with any data in any storage using any pr
After the sync command starts the UNIX system with the reboot command, the system prompts for an error message, and some applications do not work correctly. After careful examination of the system files, and compared with the initial correct backup, found that some files are really destroyed, and can not find the cause of the file corruption, and finally think of the write Cache command--sync, before reboot
After the Sync command starts the unix system with the reboot command, the system prompts an error message. Some applications cannot work normally. After carefully checking the system files and comparing them with the initial correct backup, we found that some files were indeed damaged and we could not find the cause of the file being damaged, finally, I thought of writing the cache command-sync. I didn't r

In the previous section, we said that knowledge is the metadata (metadata) in Microsoft sync framework. This metadata is used to describe all changes applied to replica. These changes are either direct, or through synchronization.
MSF uses knowledge to enumerate changes and conflict detection.
Change enumeration and Conflict Detection generally compare the versions of the same item in two copies. A typical practice is that destination sends the ve

Sync is a method of CANopen to manage the synchronous data receiving and dispatching of each node, which is equivalent to the network beats, and the synchronized PDO performs real-time data transmission according to this network beat. Sync belongs to the production/consumption mode of communication, there is only one sync producer in the network, there are genera

Background Sync is Google's new web API that can delay sending user behavior until the user's network connection is stable. This helps to ensure that the data that the user wants to send is the actual data sent.The problems that exist todayNetwork is the most time to kill users, time wasted on the network waiting for page loading, Web page rendering and other loading data aspects. But there are a lot of times when you don't want to waste time and more

written data volume and the status of the I/O data buffer. although the time interval for non-synchronization is very short, if the power is down or the system crashes during this period, the written data cannot be written to the disk and will be lost.
Note: The kernel "writes" the data in the buffer zone to the standard input disk file. Here "write" is not to move the data in the buffer zone to the disk file, but to the disk file, in this case, a backup of the buffer content is retained in the
The 'Log file sync' wait event in the RAC database is more complex than the 'Log file sync' wait event in the Standalone Database, mainly because the RAC database needs to synchronize the SCN to all instances.

There are three ways to set up Sync folders.

There are three ways to first associate the synchronization installer:
The first time you start the synchronization assistant, there will be a prompt interface (as shown below), click "Enable this feature" to be associated with the Sync installer, and you can enjoy the ability to double-click IPA for installation.
Method Two: You can also enter the synchronization assistant "parameter Settings", in the basic settings, check "Associating
