（5）Master server is according to business logic processing business.
The detailed process of message synchronization method is as shown in figs 1-9, specific as follows：
（1）Some producer's (application or service) on source server Server1 generates a piece of news, and message is with BSM messages
For.The message is distributed to messaging bus Message Queues.As shown in Figure 2.
（2）APSB services and DataAdapter services on source server Server1 are all disappearing for BSM messages
Fei Zhe, therefore they can receive the BSM messages from messaging bus.As shown in Figure 3.
（3）DataAdapter services parsing BSM messages are simultaneously deposited into database D B, realize source server Server1
The persistence of upper message.As shown in Figure 4.
（4）Whether the APSB service inspections message on source server Server1 has synchronous mark, currently without increasing
Add a synchronous mark to BSM messages for ensuring that message will not be returned to from a server (destination server Server2)
Current server (source server Server1).BSM messages with synchronous mark are released to isochronous queue Replication
Queues, as shown in Figure 5.
（5）If APSB services receive the BSM messages from messaging bus Message Queues be with synchronous mark,
So, which will not all be distributed to isochronous queue, but can be simply discarded.
（6）The APSB services of another server (destination server Server2) receive the server (source server
Server1) the BSM messages in isochronous queue Replication Queues.As shown in Figure 6.
（7）The BSM messages with synchronous mark are distributed to destination server by APSB services on destination server Server2
The messaging bus Message Queues of Server2.As shown in Figure 7.
（8）APSB services and DataAdapter services on destination server Server2 receive BSM messages, because being somebody's turn to do
Message includes synchronous mark, and message can be serviced by APSB and directly be abandoned, to ensure that message does not return to source server
Server1.As shown in Figure 8.
（9）DataAdapter service parsing BSM messages on destination server Server2, and it is deposited into purpose service
In the database D B of device Server2, as shown in Figure 9.The step realizes that service message is lasting on destination server Server2
Change, also ensures that source server Server1 is synchronous with destination server Server2 data.From source server Server1 to purpose
Server S erver2 message synchronization processes, which take, is less than 1ms.When any one server delay machine is safeguarded, take over business
Server can obtain complete business datum by database D B.
（10）If message is generated, the data of Server2 to Server1 by certain producer's (application or service) of Server2
It is similar to synchronize flow flow synchronous with the data of Server1 to Server2.
