There is less information about the main and the main, reducing the impact of efficiency. Description

1 is the schematic flow chart of each synchronization method in the present invention.

3 is a schematic representation of each of the synchronized devices in the present description

Hugh way

The following is a detailed description of this step in conjunction with the Hugh method.

In the current management system, all are connected, and the ones are provided by various businesses. J BC (JaVa aaBase Co ec vy, JaVa connection) and JBoss (J2EEJaVa 2 a OE e seEd o , JaVa2 platform)), I want, first pass JBoss Jca (J2EECo eco ach ec e, J2EE connector) Connected, then or operate, and Jca is still connected to J BC, which means that Hugh is transparent, so you can consider the package-mode repackaging operation and the daily mercury on the Jca connection. In each of the necessary operational information. On the other hand, operations and things are inseparable, so they need to be separated in the package connection. Each.

This scheme first operates the information generation, mercury in each number of operations, and then operates on each of the parsing operations, the final incremental operation, with each sum

The same synchronization.

1 is a schematic flow chart of the various sums and synchronizations in the present specification. For the purpose of illustration, the concepts of operating mercury components, components, receiving components, and analyzing components are cited. It operates on mercury components and components in the main and receiving components and the number analysis components.

As shown in Figure 1, the method flow of each and every synchronization includes

Za

1. Operation of the mercury component stored in or , SQ (ST c edQ eTy a g age, chemical)

2. Operation Mercury component to SQ or storage generation number Operation

3. Operation Mercury components will operate Mercury to

Component-prescribed master and log files

4. In operation and mercury operation, connect transparently to the number of packages, not

5. Component Operation The operations in the master and log files of the mercury component are agreed upon and the component will be received.

each 1. The receiving component receives the operation that is not autonomous, and will operate the analysis component to agree on each log file.

2, analysis component Receive component agreed to each and in the log file operation

3. Analyze the operation of component analysis,

Each

4. Analyze component operations.

The steps involved in this section below.

Operational

In the case of a connection, the package mode will be connected to the connected package, and then the operation of the phase, the purpose of the package is, and the connection is still connected, not to.

The operation can be divided into the operation of the SQ and the operation of the line storage, the operation of the line storage, all of the operations of the SQ, because of the operation, only the need, the update

Operation.

Second, generate based on each operation

Forced to operate and analyze each

The connection, in the operation of mercury, in addition to the need for SQ or storage of mercury, the need for other phases of mercury, for example.

There is no point of control, and the connection can be divided. The following is a separate connection to generate an operation based on each. ( ) the connection in each matter

I have my own things and systems, more than a lot.

Each provides a management container that is not managed. For the operations that exist in each package, the package is connected, and each management container has 5 (oba) in each management container. However, if there is a connection in the package of Goba, if multiple connections are included, each connection may be different from each other, so the connection is Zhongdu Goba. , not including how many different connections, how many different, only need to pass through the Goba in each connection can be the only one.

( ) is not in each connection

For connections that are not in each, the commit or operation that can be connected to the peer is not the same. Similarly, since the connection may be operated multiple times, the connection needs to be connected in the package connection (Co ec o ) and the connection 5 or the operation (Go p ), the line commit or operation, Go p 1, You only need to use the combination of Co ec o + Go p to make a cup.

In the operation of mercury, it is possible to put mercury into the agreed master and log files.

0 efficiency. In this case, the mercury-operated model of the operation of the mercury will be assigned to the operation, and in the same consumer, the mercury will be transferred to the main and log files, and the effect of the strategy efficiency will be very small or even negligible. With the same operation as the column operation, 5 operations of mercury in the main and log files The order is complete, and the rabbit can lose in each operation due to the SQ or the order of storage.

Third, the main and will operate to each

The operation of the master and each is a very important interface in the synchronization, the operation in the main and the other, must be in the main and the same.

There are many factors in operation, including the main and

The components are not working or not working properly, and the receiving components are not working or not working properly.

In the same situation, etc., it is not that stable and different operations cannot be established. In this case, the program and the same message and system are resolved. The following operations are established and the operation is reliable.

( ) each effort to establish operations

( ) The master and the customer who established the operation

( ) Each of the designated supervisory offices is not self-contained, the main and the unsuccessful, the roads are successfully established, the same, the receiving operation and the information, the same in the main and the same message, if the handshake is lost, the main Everything is the same or not working, this

, the same is the main and the re-directed to each, if the prisons are not self-contained until the operation

Successfully established again

Information received by each returnee and operation

The operation generates the information of the returning master and the same, the main and the waiting for each operation, until the return information In each operation, the throughput is doubled, and the efficiency of the operation is likely to be halved. Therefore, the following strategies are the same as those of the same operation.

1. Master and operation Mercury component sub-file Mercury operation, main and components and main and operation Mercury component agreed master and log files The following contents of the mercury file

The top ten files of the file format system

The line of the file

After the file is full of fixed lines, file 1 is generated in file format to generate the next file.

2, the main and components to each receiving component

Operation, the following content

File, operation, line information in the file, only cup operation

Delete the result of the file of the file to the agreed line

(T e ), otherwise □a se )

3. Each receiving component receives the operation, parses out the file in the file, manipulates the line in the file, deletes the information of the file in the file, and updates the line of the file and operation in the file to the persistent file. The most operational mercury that is successfully received, each. Similarly, if the e of the deleted file is deleted, the file will be returned to the master, and the master will receive the operation file of the file later.

4, each request for the operation of the main and the The most received (line of the file ten operations in the file), will return the main and the main and file, the operation of the line information in the file, to the desired operation, as shown in Hugh 2.

The above road establishes the strategy and operation and strategy, obtains the effect and deletes the completed operation, and prevents the relocation of the operation required to take up too many of the same and the same, and prevents the deletion of the operation. There is less information lost to the main and the main, reducing the impact of efficiency.

Each receiving component will receive the operation of each mercury into the same analysis component in the different documents.

Analysis of each and every operation

Analysis of each operation and analysis of the components are not completed, mainly to complete the work

( ) analysis of operations in each operation, Co ec o Go p and Goba, of course

If the information is created, and the method exists, Goba exists. Goba is used for each force, otherwise Co ec o + Go p is used. All the operations are in the same place, each of which is a submission or operation.

( ) This is the most intervening operation, in the connection of each medium, the connection to the connection you are connected to. Yu Operation, each of the removed, each removed connection, and then you take the connection from the source, the most connected operation.

In the use of this to improve the efficiency of synchronization, you can synchronize the various ways, the only way you need to synchronize on the wood, you will be able to synchronize each other in the same medium, synchronize each of you, each synchronization principle On, .

Synchronization each has its own components

Operation Mercury components can be shared separately from each other, with different synchronizations. Each will operate the mercury into different master and log files, and each file can be synchronized with the following rules. 1Og

Component Synchronization Each deploys its own components, and the components work in the same way as the sheep. They are the same in the naming rules of the main and log files required for the operation and the different receiving components.

Receive component synchronization Each deploys its own receiving component, the way the components work in the same way as the sheep, the same way that the main and different components are built.

Analysis Component Synchronization Each deploys its own analysis component, which works in the same way as the sheep.

The above changes in the C aspect, the synchronization of multiple synchronizations, greatly improved the efficiency of synchronization. 3 is a schematic representation 3 of each of the synchronized devices in the present description, including device operation, operation generation, operation, and operation.

The operation information of the master and the operation information of the master and the supplied master and the operation information includes line-stored operation information and updated operation information. The rest scheme includes the overnight packaging mode that will be required to connect to the package, and then the phase operation, ie the main and the operation.

The operation generates the operation information, and generates the main and the operation. The generated master and operation are for each operation, and the strategy for each operation includes

If the connection in each of the connections does not generate a primary sum operation, then each of the management containers in the global pool is not the only cup, then the connection to the peer connection or

The combination is not the only one.

Operation, the main and the operation of each. Operation in the main and the operation, each and the same message success and system, to the main and operation

Each.

Operation, to save each received operation.

The operations include 敖搪 each child, a linker, and a child. Each child is in each operation. If there is a Goba, then Goba is used to force each other. If there is no Goba, then the combination of the commit or the connection connected to the same media, ie Co ec o + Go p, is used to connect each link. Each connection is connected, the connection to which you are connected is mapped to each operation, the connection is taken out, and the connection in the operation is taken out from the source, the most connected

Operational.

The above-mentioned Hugh, the purpose, the wood and the beneficial effects are explained in detail, and it is noted that the above-mentioned powers of the field can be different from the spirit of the field. , if the modification of this paragraph and the wood of this requirement and its equivalent are also included

And within.
