Description

TECHNICAL FIELD

[0001] The present application relates to the field of artificial intelligence, and in particular to a dynamic control message concurrent processing method and device. BACKGROUND

[0002] This section is intended to provide background or context to the embodiments of the application recited in the claims. The description herein is not admitted to be prior art merely by inclusion in this section.

[0003] The existing commercial bank uses MQ middleware (Websphere MQ, a commercial messaging middleware, Websphere MQ provides an industrial standard, safe and reliable message transmission system) in software development to perform message transmission. After receiving the message, the commercial bank triggers the message processing program using the trigger mechanism of MQ to perform subsequent business processing.

[0004] If the trigger program is an online transaction program defined by CICS (Customer Information Control System, a transaction processing environment for commercial applications, a transaction middleware), it will be found that if the EVERY trigger mode is used, the system will have obvious "shock" due to the inability to control the time of message arrival, and when a large number of messages arrive at the same time, too many processing programs will be started in CICS, and if not controlled, CICS will even be crushed. Therefore, the EVERY mode is usually not a good trigger mode for CICS programs. When the FIRST mode is used, only one trigger program is called by MQ at each time, and the concurrency degree is obviously insufficient, and when the transaction volume is large, it may form a performance bottleneck.

[0029] To make the objects, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application are further described in detail below with reference to the drawings. Herein, the illustrative embodiments of the present application and the descriptions thereof are used to explain the present application, but not to limit the present application.

[0030] Figure 1 An embodiment diagram of a dynamic control message concurrent processing method according to an embodiment of the present application is shown in FIG. 1, which provides a dynamic control message concurrent processing method according to an embodiment of the present application. Figure 1 The method designs message control and message processing separately, and dynamically starts message processing programs through a reasonable algorithm, so that the existing resources can be used to the maximum extent, the concurrent processing capability of the system is improved, and the business processing requirements are met. The method comprises the following steps.

[0031] Step 101: initializing message processing parameters;

[0032] Step 102: obtaining the queue depth of a current MQ queue and the number of message processing programs currently running; the message processing program is used to process messages in the MQ queue;

[0033] Step 103: determining the number of message processing programs needed to be started again for the current MQ queue according to the initialized message processing parameters, the queue depth of the current MQ queue and the number of message processing programs currently running;

[0034] Step 104: starting the corresponding number of message processing programs in sequence according to the number of message processing programs needed to be started again for the current MQ queue, and processing messages in the MQ queue;

[0035] Step 105: after waiting for a set time length, the queue depth of the next time MQ queue and the number of message processing programs running at the next time are acquired circularly, the number of message processing programs needed to be started again by the next time MQ queue is determined circularly in combination with the initialized message processing parameters and is started in turn until the queue depth of the MQ queue is zero.

[0036] The method and device for dynamically controlling message concurrent processing provided by the embodiment of the application comprise: initializing message processing parameters; acquiring the queue depth of a current MQ queue and the number of message processing programs running at present; the message processing program is used for processing messages in the MQ queue; according to the initialized message processing parameters, the queue depth of the current MQ queue and the number of message processing programs running at present, the number of message processing programs needed to be started again by the current MQ queue is determined; according to the number of message processing programs needed to be started again by the current MQ queue, a corresponding number of message processing programs are started in turn to process messages in the MQ queue; after waiting for a set time length, the queue depth of the next time MQ queue and the number of message processing programs running at the next time are acquired circularly, the number of message processing programs needed to be started again by the next time MQ queue is determined circularly in combination with the initialized message processing parameters and is started in turn until the queue depth of the MQ queue is zero. The message master and the message processing are designed respectively, and the message processing program is started dynamically through a reasonable algorithm, so that the existing resources can be used to the maximum extent, the concurrent processing capacity of the system is improved, and the business processing requirements are met. The application overcomes the defect that the concurrent processing degree of the traditional design mode is obviously insufficient, and through the control program and the specific algorithm, the message processing program is started dynamically according to the size of the message to be processed, so that the existing resources can be used to the maximum extent, the concurrent processing capacity of the system is improved, and the timeliness requirements of the business are met.

[0037] In the embodiment of the application, the professional glossaries involved are as follows:

[0038] CICS: Customer Information Control System, namely, a customer information control system, which provides a transaction processing environment for business applications and is a transaction middleware.

[0039] MQ: Websphere MQ, which is a commercial communication middleware of IBM. Websphere MQ provides a message transmission system with industrial standards, safety and reliability.

[0040] Queue depth: expression of the number of messages in the MQ queue.

[0041] Trigger mode: the processing mode of MQ to the received message. There are two trigger modes: EVERY and FIRST. EVERY is to trigger the defined transaction processing for each transaction, and FIRST is to trigger the defined transaction processing when the queue depth changes from 0 to 1.

[0042] In the design of large enterprise applications, the performance of the program in large transaction volume must be considered, and the highest processing efficiency must be provided. When the current bank payment system processes MQ messages, the FIRST mode is usually used, and only one trigger program is called by MQ at each moment. Due to the obvious lack of concurrency, a large number of messages are accumulated in MQ when the transaction volume is large, forming a performance bottleneck. Their solution is to increase hardware resources and expand the number of MQ queue configurations to relieve performance pressure. The existing system processing mechanism is that only one trigger program is called by MQ at each moment. When the number of messages is not large, the business processing requirements can be basically met, but when the number of messages is large, due to the obvious lack of concurrent processing, a large number of messages will be accumulated in MQ, forming a performance bottleneck, and the timeliness requirements of customers cannot be met.

[0043] The purpose of the present application is to dynamically start the message processing program through the control program and the specific algorithm, so as to maximize the use of existing resources, improve the concurrent processing capability of the system, and meet the business processing requirements.

[0044] Figure 2 A flowchart of a dynamic control message concurrent processing method according to an embodiment of the present application is shown in FIG. 1. Figure 2 When the dynamic control message concurrent processing method according to an embodiment of the present application is implemented, in one embodiment, it is applied to a control program, and the control program is used to start a message processing program to process messages in an MQ queue. The method comprises the following steps.

[0045] Initializing message processing parameters;

[0046] Obtaining the queue depth of the current MQ queue and the number of currently running message processing programs; the message processing program is used to process messages in the MQ queue;

[0047] According to the initialized message processing parameters, the queue depth of the current MQ queue and the number of currently running message processing programs, determining the number of message processing programs that need to be started again for the current MQ queue;

[0048] According to the number of message processing programs that need to be started again for the current MQ queue, starting a corresponding number of message processing programs in sequence to process messages in the MQ queue;

[0049] After waiting for a set time length, the queue depth of the MQ queue at the next time and the number of message processing programs running at the next time are acquired in a loop, and the number of message processing programs needed to be started again by the MQ queue at the next time is determined in a loop in combination with the initialized message processing parameters and is started in turn until the queue depth of the MQ queue is zero.

[0050] To solve the concurrency problem of the MQ trigger in a large transaction volume environment, the application provides a relatively simple method: a control program processes the message mode. The control program is a trigger program defined in the MQ, and its function is to start a certain number of message processing programs and can be dynamically adjusted. There is only one control program running at any time in the system, and its responsibility is to only use the MQINQ command to obtain information such as the queue depth and the number of message processing programs on the queue. The control program does not directly read the message data in the queue. The message processing program is the real message processor, and each message processing program reads data from the input queue to process the business. The message processing program does not stop processing messages one by one until the queue is empty. The number of message processing programs can be controlled by the control program. The control program uses a specific algorithm to determine and control the number of message processing programs. The control program can obtain the queue depth and the number of message processing programs opened for the queue through the MQINQ command. The control program can set the initial value, the growth value, and the maximum value of the number of processing programs. At the first start, the initial value number of processing programs is started, and then the control program enters the delay (DELAY). After a few seconds, the control program wakes up and checks the queue depth and the number of message processing programs again. If the queue depth is still increasing, it indicates that the processing capacity is insufficient, and more message processing programs are started. This continues until the queue depth is 0, and the control program exits.

[0051] When the dynamic control message concurrency processing method provided by the embodiment of the application is implemented, in one embodiment, the queue depth of the current MQ queue is acquired, including:

[0052] The API function MQINQ of the MQ is called to obtain the queue depth of the current MQ queue. The queue depth is the number of messages in the current MQ queue.

[0053] When the dynamic control message concurrency processing method provided by the embodiment of the application is implemented, in one embodiment, the number of currently running message processing programs is acquired, including:

[0054] The CICS command is called to obtain the number of currently running message processing programs.

[0055] In the embodiment, the message processing is first parameterized, including initial value, growth value and maximum value of the number of processing programs; then the queue depth of the current MQ queue is obtained by calling the API function MQINQ of MQ; and then the number of currently running message processing programs is obtained by calling the CICS command.

[0056] Figure 3 An embodiment of the dynamic control message concurrent processing method is shown in the figure. Figure 3 As shown in the figure, when the dynamic control message concurrent processing method is implemented, in an embodiment, the initialized message processing parameters include: initial value, growth value and maximum value of the number of message processing programs.

[0057] According to the initialized message processing parameters, the queue depth of the current MQ queue and the number of currently running message processing programs, the number of message processing programs needed to be restarted for the current MQ queue is determined, including:

[0058] Step 301: when the queue depth of the current MQ queue is less than or equal to the first set value, the initial value is taken as the number of message processing programs to be started;

[0059] Step 302: when the queue depth of the current MQ queue is greater than the first set value and less than or equal to the second set value, the sum of the initial value and the first growth value is taken as the number of message processing programs to be started;

[0060] Step 303: when the queue depth of the current MQ queue is greater than the second set value and less than or equal to the third set value, the sum of the initial value and the second growth value is taken as the number of message processing programs to be started;

[0061] Step 304: when the queue depth of the current MQ queue is greater than the third set value and less than or equal to the fourth set value, the sum of the initial value and the third growth value is taken as the number of message processing programs to be started;

[0062] Step 305: when the queue depth of the current MQ queue is greater than the fourth set value, the maximum value is taken as the number of message processing programs to be started;

[0063] Step 306: the number of message processing programs to be started is subtracted by the number of currently running message processing programs to determine the number of message processing programs needed to be restarted for the current MQ queue.

[0064] The most important change in the embodiment is from the traditional mode of thinking to the flexible technical decoupling mode, and the message operation is split into two parts of message master and message processing. The difficulty lies in the algorithm design, that is, according to the depth of the current queue, the number of message processing programs needed is calculated to realize the dynamization and intelligentization of message processing.

[0065] Specifically, according to the initial value, the growth value and the maximum value of the number of processing programs, the depth of the current MQ queue and the number of currently running message processing programs, the number of message processing programs needed to be started again is determined, for example: 1) when the queue depth is 500, the initial value of the number of message processing programs maintained in the startup parameter is used as the number of message processing programs to be started; 2) when the queue depth is greater than 500 and less than 1000, the initial value + 1* growth value of the number of message processing programs is needed, which is used as the number of message processing programs to be started; 3) greater than 1000 and less than 2000, the initial value + 2* growth value of the number of message processing programs is needed, which is used as the number of message processing programs to be started; 4) greater than 2000 and less than 100 million, the initial value + 4* growth value of the number of message processing programs is needed, which is used as the number of message processing programs to be started; 5) more than 100 million, the maximum value of the number of message processing programs maintained in the startup parameter is needed, which is used as the number of message processing programs to be started; the number of message processing programs to be started obtained by the algorithm is reduced by the number of currently running message processing programs, and the number of message processing programs to be started again is obtained.

[0066] Figure 4 An embodiment of the dynamic control message concurrent processing method of the embodiment is shown in the figure. Figure 4 When the dynamic control message concurrent processing method provided by the embodiment is implemented, in an embodiment, according to the number of message processing programs needed to be started again for the current MQ queue, a corresponding number of message processing programs are started in sequence.

[0067] Step 401: according to the number of message processing programs needed to be started again for the current MQ queue, the START command of CICS is called to start a corresponding number of message processing programs in sequence.

[0068] Step 402: the plurality of message processing programs started again respectively read the messages in the MQ queue for logical processing to realize the business function.

[0069] In the embodiment, according to the number of message processing programs needed to be started again for the current MQ queue obtained by the above calculation, the START command of CICS is called to start the message processing programs one by one, and the plurality of message processing programs respectively read the messages for logical processing to complete the business function. When there is no message processing, it is exited.

[0070] In one embodiment of the method for dynamically controlling message concurrent processing, the restarted message processing program stops running when there is no message to process.

[0071] In one embodiment, after waiting for a set period of time, the queue depth of the MQ queue at the next time and the number of message processing programs running at the next time are obtained, and the number of message processing programs needed to be restarted for the MQ queue at the next time is determined in combination with the initialized message processing parameters and then started one by one until the queue depth of the MQ queue is zero.

[0072] Specifically, after waiting for a set period of time, the control program wakes up, and the queue depth and the number of message processing programs are checked again. According to a specific algorithm, the needed message processing programs are started, and the next round of processing is entered. This continues until the queue depth is zero, the control program exits, and waits for the MQ system to be triggered again.

[0073] The method for dynamically controlling message concurrent processing provided by the embodiments of the present application is described briefly in combination with a specific scenario as follows.

[0074] The method for dynamically controlling message concurrent processing provided by the embodiments of the present application is implemented according to the following steps.

[0075] 1. The message processing is parameterized, including the initial value, the growth value and the maximum value of the number of processing programs.

[0076] 2. The depth of the current MQ queue is obtained by calling the API function MQINQ of the MQ.

[0077] 3. The number of currently running message processing programs is obtained by calling the CICS command.

[0078] 4. The number of processing programs needed to be restarted for the current message is determined according to the initial value, the growth value and the maximum value of the number of processing programs, the depth of the current MQ queue and the number of currently running message processing programs. For example, 1) when the queue depth is 500, the initial value of the number of message processing programs maintained in the startup parameters is started; 2) when the queue depth is greater than 500 and less than 1000, the initial value + 1* growth value of message processing programs are needed; 3) when the queue depth is greater than 1000 and less than 2000, the initial value + 2* growth value of message processing programs are needed; 4) when the queue depth is greater than 2000 and less than 100 million, the initial value + 4* growth value of message processing programs are needed; 5) when the queue depth is greater than 100 million, the maximum value of message processing programs maintained in the startup parameters is started. The number of message processing programs needed to be restarted is obtained by subtracting the number of currently running message processing programs from the result obtained according to the above algorithms.

[0079] 5. According to the result of the last step, the START command of CICS is called to start the message processing program one by one;

[0080] 6. The multiple message processing programs read the message and perform logical processing to complete the business function, and exit when there is no message processing;

[0081] 7. After sleeping for 3 seconds, the system control program wakes up and checks the queue depth and the number of message processing programs again, and starts the required message processing program according to a specific algorithm to enter the next round of processing;

[0082] 8. The process is repeated until the queue depth is 0, and the control program exits and waits for the next trigger of the MQ system.

[0083] Further, the embodiment of the present application also provides a modular example of a dynamic control message concurrent processing method, which comprises: an initialization parameter module, an MQ queue depth acquisition module, a current message processing program number acquisition module, a message processing calculation module, a message processing start module and a message processing module.

[0084] The initialization parameter module sets the initial value, increment value and maximum value of the processing program number; the MQ queue depth acquisition module obtains the current MQ queue depth by calling the MQ API function MQINQ; the current message processing program number acquisition module obtains the number of currently running message processing programs by calling the CICS command; the message processing calculation module determines the number of processing programs required to be started again according to the data obtained by the above modules by running a specific algorithm; the message processing start module starts the message processing program one by one by calling the START command of CICS according to the result calculated by the last module; and the message processing module reads the message and performs logical processing to complete the business function.

[0085] In the initialization parameter module, the initial value, increment value and maximum value of the processing program number are set to ensure the stability of the system during operation, that is, there is a basic program processing guarantee when processing a small amount of messages, and as the amount of messages increases, the processing program also increases, but there is an upper limit to the processing, which will not increase without limit, so as to ensure the original intention of the normal operation of the core system.

[0086] The embodiment of the present application places the master control program and the message processing program together, and the triggered program called by the MQ at each moment is only one, which obviously lacks concurrency, and when the transaction volume is large, it may form a performance bottleneck. Alternatively, the performance pressure can be relieved by increasing hardware resources, increasing the MQ queue manager and expanding the number of MQ queue configurations.

[0087] The embodiment of the present application designs message control and message processing respectively, and through reasonable algorithm, calculates the message processing module, dynamically starts the message processing program, can utilize the existing resources to the greatest extent, improves the concurrent processing capability of the system, meets the business processing requirements, and this point is also the protection point of the present application.

[0088] The embodiment of the present application overcomes the obvious defects of the concurrent processing degree of the traditional design mode, and through the control program and the specific algorithm, according to the size of the message to be processed, dynamically starts the message processing program, can utilize the existing resources to the greatest extent, improves the concurrent processing capability of the system, and meets the timeliness requirements of the business.
