Description

Method and device for dynamically adjusting the number of long connections

technical field

The present application relates to the field of computer communication technologies, which can be used in the financial field, and in particular, to a method and device for dynamically adjusting the number of long connections.

Background technique

In order to improve the communication efficiency between the host and the platform server and reduce the consumption of the host, a long connection is generally used for communication between the host and the platform server. "Long connection" refers to a connection that can be used for multiple communications after only one connection is established between the client and the server. Compared with short connections (only one communication per connection), using long connections can effectively reduce the time and number of connections between the host and other platforms, save resource overhead, and improve communication efficiency, but it will also increase the operation and maintenance costs of the host.

The host as a client, its business transaction will start multiple communication long connection processes at the same time to communicate with the platform server. After the connection is established, the business transaction will communicate with the platform server through the application calling the communication interface.

The number of long host communication connections is preset in the host assembly table in advance. When the host middleware system starts, the system will automatically load the preset value of the assembly table into the memory table, and start the corresponding number according to the value in the memory table. For long connections, the total number of long connections will not change during the normal operation of the host middleware system.

In the host middleware system, starting a long connection is to start a long transaction, and each transaction will occupy a certain amount of system resources. Therefore, in practical applications, it is necessary to reasonably evaluate the number of long connections according to the business volume. When the business volume grows rapidly, the number of long communication connections also needs to be adjusted to support the growth of the business volume. According to the existing technical solution, modifying the number of long connections needs to modify the assembly table and then restart the host middleware system to take effect. During the restart, external services cannot be provided, thus affecting the continuity of business transactions.

Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but not to limit the present invention.

It should be noted that the method and device for dynamically adjusting the number of long connections disclosed in this application can be used in the financial field, and can also be used in any field except the financial field. The application field of the method and apparatus is not limited.

FIG. 1 is a schematic flowchart of a method for dynamically adjusting the number of long connections provided in an embodiment of the present application. This embodiment describes the present application from a host side, and the host may be, for example, a smart phone, a tablet electronic device, a A network set-top box, a portable computer, a desktop computer, a personal digital assistant (PDA), a vehicle-mounted device, a smart wearable device, etc., the method includes the following steps:

Step S101: Acquire the number of configured long connections according to the connection invocation signal.

In this embodiment, configuring the number of persistent connections refers to the total number of persistent connections that need to be configured in the host according to business volume requirements, which is a parameter that is dynamically adjusted according to business requirements. Specifically, this parameter can be manually configured , and can also be automatically adjusted and configured by the software, for example, calculated by the artificial intelligence model by monitoring the business volume. The connection invocation signal may be sent by a timer, that is, the number of configured long connections is acquired at regular intervals. Of course, in this embodiment, the connection invocation signal may also be a program monitoring traffic volume. When the traffic volume changes abruptly issued, this embodiment does not limit it.

Preferably, the configuration long connection number can be placed in a database table, and the database is updated by manually executing SQL statements to realize the update of the configuration long connection number. number of connections.

Preferably, in order to facilitate production operation and maintenance management, the number of long connections configured in this embodiment can be placed in the configuration center, the configuration center manages the parameter, and the configuration center provides an application programming interface (Application Programming Interface, API) to dynamically refresh This configures the number of long connections. This step S101 may be further specific as follows: calling the API interface of the configuration center according to the connection call timing signal, inquiring the number of configuration long-term connections of the configuration center, and importing the number of configured long-term connections into the host memory. In this embodiment, by placing the configured persistent connection number in the configuration center and importing it into the memory by the application system, the configuration persistent connection number can be easily and quickly obtained without affecting the performance of the database, and dynamic refresh can be satisfied. demand.

Step S102: Read the host memory table to obtain the number of started long-term connections, and compare the number of started long-term connections with the configured number of long-term connections.

After the number of configured long-term connections is obtained through step S101, the number of currently started long-term connections can be obtained by reading the host memory table, and the number of long-term connections that have been started and the number of configured long-term connections can be compared to determine the current number of long-term connections. Whether the number of long connections started meets the requirements or whether it exceeds the requirements, and then perform subsequent corresponding operations according to the judgment results.

Step S103: In response to the number of activated long-term connections being less than the number of configured long-term connections, start several new long-term connections so that the number of activated long-term connections is equal to the number of configured long-term connections.

When the result of step S102 shows that the number of started long connections is less than the configured number of long connections, it indicates that the number of long connections needs to be expanded to meet business requirements, so it is necessary to start several new long connections, so that the number of started long connections is equal to the number of configured long connections .

Preferably, the number of long connections that need to be newly started can be obtained according to the comparison, and then new long connections are started one by one, and the information of the newly started long connections is stored in the memory table in turn, until the number of started long connections is equal to the configured long connection. number. In this embodiment, the long connection information may include a connection identifier, a connection switch state, an idle busy state, and the like.

Step S104 : in response to the number of activated persistent connections being greater than the configured number of persistent connections, stop several activated persistent connections so that the number of activated persistent connections is equal to the configured number of persistent connections.

When the result of step S102 shows that the number of started long connections is greater than the configured number of long connections, it means that the number of long connections is excessive for the current traffic, so it is necessary to stop several started long connections so that the number of started long connections is equal to the configured number of long connections The number of connections can release host system resources and reduce host load.

Preferably, as shown in FIG. 2 , this step S104 may further include the following sub-steps:

Step S1042: Turn off the connection switch of the last activated persistent connection.

Step S1043: Wake up the blocking state of the last activated persistent connection through a POST notification instruction, so that the last activated persistent connection process ends automatically.

Step S1044: Determine whether the number of activated persistent connections is equal to the configured number of persistent connections, if so, end the operation and enter the sleep state, if not, return to step S1041.

In addition, if the comparison result in step S102 is that the number of activated long-term connections is exactly equal to the configured number of long-term connections, no subsequent operation is required, and the dormant state is directly entered, waiting for the next connection call signal to arrive.

As mentioned above, the application can dynamically adjust the number of long-term connections to the host according to the traffic volume, and the newly added long-connection information is directly stored in the memory table. The entire adjustment process does not need to modify the assembly table, and does not need to restart the host middleware system. On the premise of business continuity, complete the adjustment of the number of long communication connections. When an abnormal situation occurs in the business, the emergency response efficiency can be improved, and the impact on the business during the abnormal period can be greatly reduced.

The present application will be described in further detail below by taking the configuration long connection parameters set in the configuration center as an example. FIG. 3 is a schematic flowchart of a method for dynamically adjusting the number of long connections provided by another embodiment of the present application. The implementation body is a long-connection dynamic adjustment device in the host, and the method includes the following steps:

Step S301 : according to the timing signal of the timer, initiate a request to the configuration center for querying the number of configured persistent connections, and the configuration center returns the configured persistent connection number to the persistent connection dynamic adjustment device after receiving the request.

Step S302: Query the host memory table to obtain all the persistent connection information that has been started so far, and the persistent connection information may include the total number of activated persistent connections, the connection switch status of each persistent connection, and the like.

Step S303: Determine whether the number of activated long-term connections is equal to the number of configured long-term connections, if so, proceed to step S304, and if not, proceed to step S305.

Step S304: The persistent connection dynamic adjustment device enters a dormant state, and the dormancy time can be set by a timer. After the timer sends a working signal, the persistent connection dynamic adjustment device can continue to work in step S301.

Step S305: Determine whether the number of activated long-term connections is less than the number of configured long-term connections, if so, go to step S306, if not, go to step S307.

Step S306: Start a new persistent connection, update the new persistent connection information in the memory table, and then return to step S302.

Step S307: Find the last activated long connection from the host memory table, turn off the corresponding connection switch, then update the memory table, and go to step S308.

Step S308 : wake up the blocking state of the persistent connection through the POST notification and return to step S302 , when the persistent connection switch is in the off state and in the blocking state, the persistent connection process will automatically end.
