[0002] In the past, the core banking systems of my country's large banks were mostly based on host technology and built with a centralized architecture. However, with the continuous increase in business transactions, the core banking system has changed some applications from centralized deployment to distributed deployment, and moved transactions to the core banking system host system, thereby reducing unilateral dependence on the host, achieving independent control, and reducing security risks and costs.

[0003] In the process of moving core bank host system transactions to distributed systems, the SAGA (Smart Alliance Grid Architecture) model, which is highly compatible with the transaction processing logic of the bank host system, is usually used to process distributed transactions in a distributed system. However, the SAGA model is difficult to ensure transaction consistency and fund security in a distributed system. Summary of the invention

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0023] Embodiment 1

[0024] Figure 1 This is a flow chart of a transaction processing method provided in the first embodiment of the present application. This embodiment is applicable to the case where the host system is moved down to the distributed system for transaction processing. The method can be executed by a transaction processing device, which can be implemented in software and / or hardware, such as Figure 1 As shown, the method specifically comprises the following steps:

[0025] S110. According to the SAGA distributed transaction model, perform transaction processing on any transaction in the transaction execution sequence corresponding to the distributed transaction; wherein the transaction processing includes at least one processing node.

[0026] The SAGA distributed transaction mode (hereinafter referred to as the SAGA mode) is a distributed transaction implementation mode based on compensatory transactions. In the SAGA mode, a distributed transaction can include multiple transactions, each of which supports forward transactions and reverse compensatory transactions. When the distributed transaction of the SAGA mode is executed, the forward transactions of each transaction are executed in sequence. If the forward transactions of all transactions are executed successfully, the distributed transaction is completed and submitted. If the forward transaction of any transaction fails to execute, the distributed transaction will execute the reverse compensatory transaction corresponding to the previously completed forward transaction, that is, roll back the successful forward transaction, so that the distributed transaction returns to the initial state. The SAGA mode has a high degree of adaptability to the transaction processing logic of the host system, and the transaction processing of the distributed system can be realized by moving the host system down without making major improvements to the SAGA mode.

[0027] Usually, the transaction chain of a distributed transaction will be executed in a certain business execution order, that is, each transaction in a distributed transaction is processed in the transaction execution order. The transaction execution order corresponding to the distributed transaction can be the business execution order or the transaction execution order corresponding to the SAGA mode. For example, the execution order of the loan transaction corresponding to the distributed transaction can be to verify the legitimacy of the customer's account, verify the account password, the amount of the deductor and the amount of the transferor, etc. Any transaction can be any transaction A1, A2, ..., An in the SAGA mode. For example, a transaction can be a loan transaction.

[0028] Exemplarily, the distributed master control can perform transaction processing on any transaction in the transaction execution order corresponding to the distributed transaction according to the SAGA distributed transaction mode. Among them, the distributed master control can serve as a distributed system application gateway, which is a unified entrance to the distributed system, and is mainly responsible for providing access control, security control, public application inspection, and distributed transaction global transaction number allocation for application processing or transaction processing. The distributed transaction global transaction number is the distributed ID. Among them, the transaction processing process of each transaction can include at least one processing node. Different transactions can be processed by different server nodes in the distributed system, and the distributed master control initiates and calls each server node. For example, transaction processing may include fund processing or other business processing, wherein fund processing may be transfer processing and other processing involving fund transfer, and other business processing may be quota processing, credit review processing, or information registration processing.

[0029] In an optional embodiment, before performing transaction processing on any transaction in the transaction execution sequence corresponding to the distributed transaction according to the SAGA distributed transaction model, it also includes: determining a target verification program corresponding to any transaction from preset candidate verification programs; verifying the transaction according to the target verification program to determine whether the transaction passes the verification; if so, performing transaction processing on any transaction in the transaction execution sequence corresponding to the distributed transaction according to the SAGA distributed transaction model.

[0030] The candidate verification program can be pre-set by relevant technical personnel. Exemplarily, the verification programs corresponding to different transactions can be pre-stored in the server associated with the processing node corresponding to each transaction. The target verification program can be a verification program corresponding to any transaction in the candidate verification program deployed in the server associated with each processing node. Among them, the candidate verification program can include account password verification, card number existence verification, card number freezing verification, deposit legitimacy verification and transaction channel verification.

[0031] Exemplarily, a target verification program corresponding to any transaction is determined from preset candidate verification programs; the transaction is verified according to the target verification program to determine whether the transaction passes the verification; if so, any transaction in the transaction execution sequence corresponding to the distributed transaction is processed according to the SAGA distributed transaction mode; if not, a transaction verification failure reminder message can be sent to relevant personnel, and the transaction processing can be terminated. Among them, the transaction failure reminder message can be a reminder of the failure reason of the verification failure, for example, the transaction failure reminder message can be an account password verification failure or a card number does not exist, etc., and the relevant staff can set different transaction failure reminder messages according to different transactions.

[0032] This optional embodiment verifies any transaction according to a preset target verification procedure associated with any transaction before processing the transaction, determines whether the transaction passes the verification, and if so, executes subsequent transaction processing, thereby improving the security of the subsequent transaction processing process and avoiding economic losses caused by information verification errors or information omissions of the transaction parties.

[0033] S120. If the processing node of the transaction is a fund transfer node, the fund flow information of the transaction is obtained, and the fund flow information is sent to the fund processing center, so that the fund processing center can prepare for fund transfer of the transaction based on the fund flow information and the TCC distributed transaction model.

[0034] Among them, the fund transfer node is used for fund processing, that is, any fund processing in the transaction, such as loan or deposit. Fund flow information may include the initiation time, initiation amount and remaining amount. The fund processing center can be a server node for fund processing in a distributed system. For example, the fund processing center confirms and releases funds.

[0035] The TCC distributed transaction mode (hereinafter referred to as the TCC mode) is the abbreviation of the three operations of try or prepare operation (Try), confirm operation (Confirm) and cancel operation (Cancel). The TCC mode ensures the atomic submission of distributed transactions through atomicity, controls the concurrent access of distributed transactions through business isolation, and the transaction consistency of distributed transactions.

[0036] The business meanings of the three operations in the TCC mode are as follows: The Try phase is used to complete all business checks and reserve necessary business resources. Among them, the business can be a fund processing business; Confirm phase: the actual business logic is executed, the business is confirmed and submitted, no business checks are performed, and only the business resources reserved in the Try phase are used. By default, the Confirm phase will not go wrong. As long as the Try succeeds, the Confirm will succeed; Cancel phase: when an error occurs in the business execution and a rollback is required, the business is canceled and the reserved business resources are released.

[0037] For example, the distributed master control can send the acquired transaction fund flow information to the fund processing center. After acquiring the fund flow information, the fund processing center performs preparation processing on the transaction based on the TCC distributed transaction mode, that is, performs a Try operation on the transaction.

[0038] S130, determining whether any processing node of the transaction has been executed successfully, and if so, determining whether the transaction is a target transaction in a preset arrangement order in the transaction execution sequence.

[0039] Among them, any processing node may include a fund transfer node and other business processing nodes. For example, other business processing nodes may be processing nodes for quotas or information review processing nodes, etc. The preset arrangement order may be preset by relevant technical personnel, for example, the preset arrangement order may be the position of the last processing node in the transaction execution order. The target transaction may be the transaction corresponding to the last processing node in the transaction execution order.

[0040] Determine whether all the processing nodes of the transaction have been executed. If so, determine whether the transaction is the target transaction arranged at the last position in the transaction execution order.

[0041] S140: If yes, a confirmation instruction of fund transfer is sent to the fund processing center, so that the fund processing center can confirm the preparation process of fund transfer for any transaction in the transaction execution sequence.

[0042] Exemplarily, if the transaction is a target transaction in a preset arrangement order in the transaction execution sequence, for example, the transaction is the last transaction in the transaction execution sequence, then it can be determined that all transactions corresponding to the distributed transaction have been executed. A confirmation instruction for fund transfer can be sent to the fund processing center through the distributed master control. After receiving the confirmation instruction for fund transfer, the fund processing center performs a confirmation operation on the preparation processing of fund transfer of any transaction in the transaction execution sequence, that is, the fund processing center performs a confirmation operation on the fund transfer of any transaction that has been successfully tried according to the TCC mode.

[0043] In an optional embodiment, a distributed transaction corresponds to a unique distributed ID, and the fund flow information includes the distributed ID; the fund processing center includes the fund flow information of multiple distributed transactions; accordingly, a confirmation instruction for the fund transfer is sent to the fund processing center, so that the fund processing center can confirm the preparation processing of the fund transfer of any transaction in the transaction execution sequence, including: sending a confirmation instruction for the fund transfer corresponding to the distributed ID to the fund processing center, so that the fund processing center can determine the target fund flow information according to the distributed ID, and confirm the preparation processing of the fund transfer corresponding to the target fund flow information.

[0044] Among them, the distributed ID (Identity) can represent the unique identification of a distributed transaction in a distributed system. For example, the distributed ID can be generated by the snowflake algorithm. The ID generated by the snowflake algorithm is a 64-bit long number, which is an increasing number and can be used for sorting. The snowflake algorithm can basically maintain global uniqueness. The target fund flow information can be the fund flow information corresponding to each transaction under the distributed ID.

[0045] Exemplarily, the distributed master control can generate a distributed ID and transmit it to any transaction, that is, the distributed ID of each transaction in the transaction execution order of a distributed transaction is the same; in the process of fund processing for any transaction, when the fund flow information is sent to the fund processing center, the distributed ID of the transaction is included in the fund flow information. When the fund transfer of any transaction is fully prepared (that is, all tries are successful), the distributed master control can initiate a fund transfer confirmation instruction corresponding to each transaction under the distributed ID to the fund processing center through the distributed ID; when the fund processing center receives the fund transfer confirmation instruction, it determines the fund flow information under the distributed ID as the target fund flow information, and confirms the preparation processing of the fund transfer corresponding to the target fund flow information, that is, the fund transfer confirmation is performed for all the fund flows with successful tries under the distributed ID.

[0046] This optional embodiment determines the unique distributed ID corresponding to the distributed transaction and initiates a confirmation instruction of the fund transfer to the fund processing center according to the distributed ID, thereby avoiding the submission error of the fund transfer action when there is at least one distributed transaction. The uniqueness and accuracy of the confirmation fund transfer instruction can be guaranteed by setting the distributed ID.

[0047] The embodiment of the present application performs transaction processing on the transaction corresponding to the distributed transaction according to the SAGA distributed transaction mode; if the processing node of the transaction is a fund transfer node, the fund processing center performs preparation processing for the fund transfer on the transaction based on the TCC distributed transaction mode according to the fund flow information; if any of the processing nodes including the fund processing node in any transaction passes, it can be determined that the transaction processing execution corresponding to the distributed transaction passes, and the fund processing center can confirm the preparation processing of the fund transfer of any transaction in the transaction execution sequence. The above scheme realizes the transaction processing in the process of moving the host system down to the distributed system and improves the fund security in the transaction processing process by extracting the fund processing from the transaction processing logic, and processing the nodes involved in the fund processing in the transaction processing according to the TCC mode, and other non-fund transactions are processed according to the transaction implementation logic of the SAGA mode. By confirming the preparation processing of the fund transfer after the transaction processing of any transaction passes, the situation that the funds cannot be withdrawn during the fund transfer process is avoided. Transaction consistency in the transaction processing process is achieved.

[0048] Embodiment 2

[0049] Figure 2 A flowchart of a transaction processing method provided in Example 2 of the present application is provided. This embodiment is optimized and improved on the basis of the above-mentioned technical solutions.

[0050] Furthermore, after the step "According to the SAGA distributed transaction model, perform transaction processing on any transaction in the transaction execution order corresponding to the distributed transaction", add the step "If the transaction processing node is an information confirmation node, obtain the transaction's pending confirmation information and confirm the pending confirmation information." to improve the transaction processing process of any transaction.

[0051] After the step of "determining whether any processing node of the transaction has been executed successfully", add the step of "if any processing node of the transaction has not been executed successfully, determine whether the processing node that has not been executed successfully is a fund transfer node; if so, send a fund transfer cancellation instruction to the fund processing center for the fund processing center to cancel the preparation for the fund transfer." Correspondingly, after the step of "determining whether the processing node that has not been executed successfully is a fund transfer node", add the step of "if the processing node that has not been executed successfully is not a fund transfer node, determine the processing nodes that have been executed successfully in the transaction, and determine the transactions that have been executed successfully according to the transaction execution order; according to the preset reverse compensation transaction rules, perform transaction rollback on the processing nodes that have been executed successfully in the transaction and the transactions that have been executed successfully in the transaction execution order." to improve the processing method for non-fund transfer nodes.

[0052] After the step "determine whether the transaction is the target transaction of the preset arrangement order in the transaction execution order", add the step "if the transaction is not the target transaction of the preset arrangement order in the transaction execution order, determine the next transaction of the transaction according to the transaction execution order as the pending transaction, and execute the transaction processing according to the SAGA distributed transaction mode for the pending transactions in the transaction execution order corresponding to the distributed transaction." to improve the processing method for non-target transactions.

[0053] like Figure 2 As shown, the method comprises the following specific steps:

[0054] S210. According to the SAGA distributed transaction model, perform transaction processing on any transaction in the transaction execution sequence corresponding to the distributed transaction; wherein the transaction processing includes at least one processing node.

[0055] S220: If the transaction processing node is an information confirmation node, the pending confirmation information of the transaction is obtained, and the pending confirmation information is confirmed.

[0056] The information confirmation node may be other business nodes except the fund transfer node, and the number of information confirmation nodes may include at least one. For example, the information confirmation node may include a quota processing node and an information review processing node. The information to be confirmed corresponds to each information confirmation node. For example, if the information confirmation node is a quota processing node, the information to be confirmed may be the quota information to be confirmed.

[0057] S230. If the processing node of the transaction is a fund transfer node, the fund flow information of the transaction is obtained, and the fund flow information is sent to the fund processing center, so that the fund processing center can prepare for fund transfer of the transaction based on the fund flow information and the TCC distributed transaction model.

[0058] S240, determining whether any processing node of the transaction has been executed successfully; if so, executing S250A, if not, executing S250B.

[0059] S250A, determining whether the transaction is a target transaction in a preset arrangement order in the transaction execution order, if so, executing S260A, if not, executing S260B.

[0060] S250B, determine whether the processing node that has not been executed is a fund transfer node, if so, execute S270A, if not, execute S270B.

[0061] S260A. Send a confirmation instruction of fund transfer to the fund processing center, so that the fund processing center can confirm the preparation processing of fund transfer for any transaction in the transaction execution sequence.

[0062] S260B. According to the transaction execution order, determine the next transaction of the transaction as the pending transaction, and execute transaction processing according to the SAGA distributed transaction mode for the pending transaction in the transaction execution order corresponding to the distributed transaction.

[0063] S270A. Send a funds transfer cancellation instruction to the funds processing center for the funds processing center to prepare for canceling the funds transfer.

[0064] For example, the distributed master control may send a fund transfer cancellation instruction to the fund processing center, and the fund processing center cancels the prepared fund transfer according to the fund transfer cancellation instruction. That is, the fund processing center cancels all fund flows that have been successfully tried.

[0065] S270B, determining the processing nodes that have been successfully executed in the transaction, and determining the transactions that have been successfully executed according to the transaction execution order.

[0066] S280. According to the preset reverse compensation transaction rules, the transaction is rolled back for the processing nodes that have been executed successfully in the transaction and the transactions that have been executed successfully in the transaction execution sequence.

[0067] Among them, the reverse compensation transaction rules can be pre-set by relevant technical personnel. For example, the reverse compensation transaction rules can be the reverse transaction in the SAGA mode, that is, the reverse compensation transaction. The transaction is rolled back for the processing nodes that have been executed in the transaction and the transactions that have been executed in the transaction execution sequence. Exemplarily, for any transaction that fails to execute, the distributed transaction will go back to execute the reverse compensation transaction of any previously completed transaction, roll back the successful transaction, and return the distributed transaction to the initial state before the transaction processing.

[0068] The embodiment of the present application achieves the comprehensiveness of the transaction processing process of any transaction by further improving if the processing node of the transaction is an information confirmation node, if any processing node of the transaction is not executed, and if the transaction is not a target transaction in the preset arrangement order in the transaction execution order. By extracting the funds processing from the transaction processing logic, and processing the nodes involved in the funds processing in the transaction processing according to the TCC mode, and processing other non-fund transactions according to the transaction implementation logic of the SAGA mode, the transaction processing in the process of moving the host system to the distributed system is realized, and the security of funds in the transaction processing process is improved. The embodiment of the present application proposes to extract the funds processing that is affected by subsequent transactions and hinders the successful transaction rollback from the transaction transformation from the transaction processing logic and uniformly implement it while the rest of the transaction implementation logic remains unchanged, thereby providing a host-downward distributed transaction implementation that has a small amount of transformation from the host's positive and negative transaction implementation logic and can ensure the consistency of distributed system transactions.

[0069] In a specific implementation, the distributed master control generates a global transaction number X (distributed ID), and submits transactions A1, A2, ..., An with global transaction number X in turn according to the execution order of the SAGA mode. Execute the verification procedure for each transaction Ai. Transaction processing is performed on Ai, including fund processing of transaction Ai, generating fund processing flow of Ai, and other non-fund business processing. Among them, the fund processing method for Ai is: send fund flow information to the fund processing center, and the fund processing center submits the try action of the fund flow with global transaction number X one by one according to the TCC mode. If a transaction Ai fails to execute, based on the SAGA mode, according to the reverse compensation transaction of the successfully executed transaction Aj, the transaction Aj is rolled back, and the distributed master control notifies the fund processing center to roll back all the successfully tried fund flows corresponding to the global transaction number X. If all transactions A1, A2, ..., An of the entire transaction chain are executed, and all try actions of the fund flow with global transaction number X are successful, the distributed master control notifies the fund processing center to execute the confirm action of all fund processing flows under global transaction number X, and the entire transaction chain is submitted successfully.

[0070] In a scenario of nested transactions, if transaction P involves distributed transactions, including services 1, 2, and 3, and service 2 includes services 4 and 5, then distributed transactions are nested. Under the premise that fund processing is separated from transactions, transaction P calls services 1, 2, and 3 in SAGA mode, and service 2 calls services 4 and 5 in SAGA mode. Only after services 4 and 5 are all successful will the distributed master control service 2 be informed of success; if any of services 4 and 5 fail, all will be rolled back and the distributed master control service 2 will be informed of failure. If service 2 fails, the successfully executed service will be rolled back.

[0071] If service 2 does not include service 4 and service 5, and service 1, service 2, service 3, service 4 and service 5 are in parallel relationship, then the entire transaction chain becomes service 1, service 2, service 3, service 4 and service 5, which are still executed in sequence in SAGA mode. If a service fails to be submitted, a compensating transaction is submitted for the successful service and all are rolled back.

[0072] For fund processing, the entire fund processing flow of the transaction is executed in TCC mode. For a specific fund flow, if its try function also involves a distributed service sub-call, it can be seen from the fact that the try action of the fund flow can be rolled back that the distributed service sub-call involved in the try action can also be rolled back, otherwise it cannot be ensured that the entire try action will be rolled back. For a certain fund flow, its confirm function involves a distributed service sub-call. It can be seen from the fact that the confirm of the fund flow can be successful that the distributed service sub-call it calls can also be successful. The distributed service sub-call can be initiated by asynchronous message notification, and it will be successful as long as the message can be delivered.

[0073] In the scenario of combining transactions between the old and new systems during the migration of the host system, it is necessary to ensure the transaction consistency of the combination of transactions between the old and new systems. The host system can be considered as a typical SAGA mode, and the newly implemented distributed system can be considered as a system that meets the conditions of the TCC mode. The TCC mode and the SAGA mode can be combined to ensure transaction consistency and fund security.

[0074] In a specific example, if business M has been moved down and business N has not been moved down, business M can be a bond business and business N can be a personal current account business. The transaction is that user A transfers 10,000 yuan to user B through business M, and user B transfers 10,000 yuan to user A through business N. The specific steps are as follows:

[0075] a. Submit the business M transfer transaction, and user A's currency is transferred to user B's fund processing flow. Try the fund processing flow, and the available balance of user A's currency account is -10,000.

[0076] b. Execute the host transaction and transfer 10,000 RMB of user B's funds to user A's account.

[0077] c. If the host transaction is successful, confirm the fund processing flow of the business M transfer transaction.

[0078] d. If the host transaction fails, cancel the fund processing flow of the business M transfer transaction and restore the available balance of the currency account of user A deducted by the Try action.

The above scheme realizes transaction processing in the process of moving the host system down to the distributed system and improves the fund security in the transaction processing process by extracting the fund processing from the transaction processing logic, and processing the nodes involved in the fund processing in the transaction processing according to the TCC model, and processing other non-fund transactions according to the transaction implementation logic of the SAGA model.
