One specific embodiment of the present invention:
the scheme structure is as follows:
terminal database data generation, data transmission, central database summary data and abnormal condition simulation
The method mainly comprises the following steps:
a: terminal database
1. The table formats of the terminal database and the central database are firstly established, the data synchronization rule is configured, the data synchronization rule comprises row and column keywords to be synchronized, and the data synchronization time is set to be 84 hours.
2. And judging whether the terminal database has data or not, and if not, using a batch insertion tool to insert the data into the terminal database in batches through JDBC driving. If any, whether the data is in the buffer area, and if not, emptying the data of the terminal database and the central server.
3. Recording the data insertion performance of the terminal database, including the insertion speed and the data storage accuracy, and if the database performance can be kept up to the data generation speed, automatically closing the database in case of overload.
4. And checking whether the database has data by using an sql statement, and if so, checking whether a sending buffer area exists. This ensures that data can be sent by time and will not resynchronize to the central repository if it has been deleted from the send buffer. If the data transmission buffer area is not in the sending buffer area, the data transmission buffer area is restarted from the step 1, if the data integrity is checked in the data buffer area firstly, the total record number is recorded, the data number of the central database is inquired after the data is synchronized to the central database, and the data transmission buffer area is compared with the database data of the central database, so that the data transmission is known whether the packet is lost or not.
B. Data transmission
1. The synchronization time of the change terminal database and the central database is 1 minute.
2. And when the data of the plurality of terminal databases are automatically synchronized to the central database within 1 minute, the performance values in the data synchronization process are recorded by using the monitoring commands carried by the databases, and the performance values comprise the data writing speed, the synchronization time delay, the synchronization time, the synchronous network throughput and other information of the central database when the data are synchronized to the central database.
3. And recording the total time for synchronization after synchronization is finished.
C. Central database terminal
1. And receiving the data sent by the terminal database end, and writing the data into the central database.
And after the synchronization is finished, inquiring the total record number, and comparing the total record number with the total record number of the plurality of terminal databases obtained in the previous step A4 to check whether the record is lost or not. If the data is lost, the problem of data processing caused by the sending and receiving queue between the databases at two ends in network transmission is shown. Meanwhile, whether the data is transmitted disorderly or not is checked in a mode of averaging or finding a maximum value, and if the data is transmitted disorderly, the problem of data processing caused by the sending and receiving queue between the databases at two ends or the problem caused by the data writing function of the database occurs. At this time, the hardware or software function has bug, and the source code needs to be modified.
D. Abnormal situation simulation test
1. The scripts for changing the firewall rules are run on the databases of the plurality of terminals to simulate the network communication quality, and the three intermittent times can be set in a staggered manner.
And after the data synchronization between the terminal database and the central database is started, recording the running condition of the database at the moment, and checking whether the running log is abnormal or not. For example, the situation that the database is automatically closed or a certain thread is hung or the client cannot be connected to the database is found, which indicates that the synchronization function design has defects in the case of poor network quality, and the development of source code modification or database configuration modification needs to be assisted.
And after the data synchronization is finished, checking whether the data of the central database is complete or not, and if the data is lost or not. If the packet is lost or the data is incomplete, the data synchronization under the condition of poor network quality can affect the normal performance of the database, and the data receiving problem is caused. The code needs to be modified at this time. If software cannot solve the problem, the architecture of the data synchronization mode cannot be used in a scene with poor network quality, and the application scene needs to be avoided when a scheme is made for a client.
Although specific embodiments of the invention have been described above, it will be understood by those skilled in the art that the specific embodiments described are illustrative only and are not limiting upon the scope of the invention, and that equivalent modifications and variations can be made by those skilled in the art without departing from the spirit of the invention, which is to be limited only by the appended claims.
