Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a diagram illustrating an abnormal bank transaction processing method according to an embodiment of the present invention, which mainly includes the following steps:
step S11, when the original transaction is abnormal, initiating a flushing request, generating an IFA dump file of the original transaction to record the transaction memory data when the original transaction is abnormal, and simultaneously writing the initial status information of flushing to be normal into a first-in first-out flushing queue to trigger the flushing to be normal service transaction.
When the original transaction is abnormal, for example, in a scene that the transaction is unknown or a unilateral account appears, a correction request can be initiated to call a correction service. When initiating a flushing request, all transaction memory data when an original transaction is abnormal need to be recorded and stored as an IFA file, that is, an internal format area file, which can be understood as a transaction memory Dump file (which is a memory mirror image of a process), and current transaction data is stored according to a certain format to be read in a subsequent flushing. Meanwhile, the initial state information of the conflict (such as the transaction serial number, the transaction date, the transaction time, the transaction code, the conflict identifier, the conflict transaction code and the like) needs to be written into a first-in first-out conflict queue to trigger the conflict service transaction to carry out asynchronous conflict.
Step S12, reading a flushing queue message from the fifo flushing queue and parsing out the flushing transaction code contained therein, so as to link the corresponding transaction scheduling engine according to the flushing orthogonal transaction code.
After triggering the forward flushing service transaction in step S11, the forward flushing service transaction module with the forward flushing service program therein may read the forward flushing queue message that is pushed to the earliest stack in the queue from the first-in first-out forward flushing queue for analysis, and obtain the forward flushing orthogonal easy code included in the forward flushing queue message, so that Link (Link) is linked to the transaction scheduling engine corresponding to the forward flushing orthogonal easy code. The correction service transaction module can be replaced by other modules with the same function. The Link refers to a program calling mode provided by a CICS (client Information Control System, a transaction middleware commonly used in a banking System) middleware.
Step S13, the transaction scheduling engine searches for a corresponding IFA dump file according to the read alignment queue message, and adapts a corresponding alignment easy flow according to the alignment transaction code to perform alignment.
After Link is sent to the corresponding transaction scheduling engine, the transaction scheduling engine may recover IFA information of the corresponding original transaction according to the forward queue flushing message read in step S12, that is, an IFA dump file of the corresponding original transaction is searched according to the forward queue flushing message (for example, transaction date, transaction time, transaction code, etc.), and the forward queue flushing message is adapted to the corresponding forward queue flushing flow according to the forward queue flushing code in the forward queue flushing message, and the forward flushing flow may utilize the IFA dump file of the original transaction to assemble the forward flushing message, initiate forward flushing call to the background system, and complete forward flushing.
The method for correcting the transaction memory data can realize automatic asynchronous correction by using a trigger mechanism of a first-in first-out correction queue and a file storage mechanism of the transaction memory data, effectively improves the correctness of a transaction result and reduces the workload of manual intervention correction.
In an embodiment, when the original transaction is abnormal and a transaction initiation request is initiated in step S11, the initial state information of the transaction initiation may be registered in an abnormal transaction flow meter to record the state of the transaction initiation.
In an embodiment, after the forward flushing operation of step S13 is finished, a forward flushing result (failure or success) is generated, and regardless of the result, the abnormal transaction flow meter may be updated according to the obtained forward flushing result, so as to record the whole forward flushing operation process.
In addition, when the original transaction in step S11 is abnormal and the normal flushing operation is initiated, the method further includes: and appointing the number of punching times of the punching operation. For example, if the default value of the number of times of flushing parameter of the current flushing request is set to 1, the flushing operation is stopped after completing one flushing operation according to steps S11-S13.
In specific implementation, if the positive error result obtained in step S13 is positive error failure, subtracting 1 from the positive error number, and determining whether the positive error number is greater than 0, if the positive error number is still greater than 0, writing the positive error queue message read from the queue in step S12 into the first-in first-out positive error queue again, that is, the positive error queue message is put on the stack again, and waiting for triggering.
In an embodiment, the fifo queue may be an instantaneous Data queue, i.e., a tdq (transient Data queue) and a CICS instantaneous Data queue, which is a fifo queue and provides a trigger mechanism.
The embodiment of the invention can realize asynchronous automatic repeated correction by utilizing a triggering mechanism of a first-in first-out queue TDQ, a memory Dump data file mechanism of transaction and an abnormal transaction flow meter.
Based on the same inventive concept as the bank abnormal transaction correction method shown in fig. 1, the embodiment of the present application further provides a bank abnormal transaction correction system, as described in the following embodiments. Because the principle of solving the problems of the system is similar to that of the bank abnormal transaction correction method in fig. 1, the implementation of the system can refer to the implementation of the bank abnormal transaction correction method in fig. 1, and repeated parts are not described again.
In another embodiment, the present invention further provides a system for correcting an abnormal transaction of a bank, which has a structure as shown in fig. 2, and the system mainly includes: the system comprises an original transaction alignment initiating module 21, a first-in first-out alignment queue module 22, an alignment service module 23 and a transaction scheduling engine 24.
The original transaction conflict initiating module 21 is configured to initiate a conflict request when an original transaction is abnormal, generate an IFA dump file of the original transaction to record transaction memory data when the original transaction is abnormal, and write initial state information of conflict into the fifo conflict queue module 22 to trigger a conflict service transaction.
The forward flushing service module 23 is configured to read a forward flushing queue message from the fifo forward flushing queue module 22 and parse a forward flushing transaction code contained therein, so as to link the corresponding transaction scheduling engine according to the forward flushing transaction code.
The transaction scheduling engine 24 searches a corresponding IFA Dump file (for example, a Dump file) according to the read alignment queue message, and adapts a corresponding alignment transaction flow according to the alignment transaction code to perform alignment.
In one embodiment, the original transaction liquidation initiating module 21 is further configured to register the liquidation initial status information to an abnormal transaction flow meter.
In one embodiment, the transaction scheduling engine 24 generates a positive result after the positive result is completed, and the positive result service module 23 updates the abnormal transaction flow meter according to the positive result.
In an embodiment, when initiating the flushing operation when the original transaction is abnormal, the original transaction flushing initiation module 21 is further configured to specify the flushing times of the flushing operation.
In an embodiment, if the positive flushing result is positive flushing failure, the positive flushing service module 23 is further configured to subtract 1 from the positive flushing number, and determine whether the positive flushing number is greater than 0, and if the positive flushing number is still greater than 0, re-write the positive flushing queue message into the fifo queue.
In one embodiment, the FIFO flushing queue module is a transient data queue module.
The system provided by the embodiment of the invention can realize asynchronous automatic repeated correction by utilizing a triggering mechanism of a first-in first-out queue TDQ, a memory Dump data file mechanism of transaction and an abnormal transaction flow meter.
To more clearly illustrate the implementation of the present invention, fig. 3 shows a positive example schematic. As shown in fig. 3, in a scenario where an original transaction is unknown or a single-sided account appears, an atomic transaction with positive flushing is called (the maximum number of positive flushing times can be specified), an IFA file (which can be understood as a Dump file) of a current transaction is generated, all transaction information when the current transaction is abnormal is recorded in an abnormal transaction flow meter, and key information (for example, information such as serial number, transaction date, positive flushing identification bit, maximum number of positive flushing times, and the like of the abnormal transaction) of the positive flushing transaction is written into a first-in first-out queue TDQ. For example, the positive initial state information may include the following: 8-bit ZeroFlag (zero Flag), 1-bit Flag (Flag), 8-bit TraceNo (transaction serial number), 8-bit TracDate (transaction date), 6-bit TracTime (transaction time), 6-bit TracCode (transaction code), 6-bit RcovTracCode (orthogonal easy code) and 6-bit RcovCount (number of positive times).
The write to the TDQ operation will also asynchronously trigger the flush service. After reading a piece of TDQ information, the correcting service program organizes correcting data, namely, reads a piece of correcting initial state information from the TDQ, and sends the correcting initial state information to a LINK transaction scheduling engine according to a transaction code in the correcting data. And the transaction scheduling engine recovers the IFA information of the original transaction according to the TDQ information (namely, searching the IFA file of the original transaction according to Trandate, TrandTime and TraceNo), adapts to the corresponding forward conflict flow according to the forward conflict transaction code RcovTransCode, assembles the forward conflict message and initiates forward conflict calling to the background system. And updating the record state (0-success, E-failure) of the corresponding abnormal transaction flow table by the correction service program according to the correction result returned by the LINK master control (namely, the correction result returned from the transaction scheduling engine). And if the returned result is positive conflict failure, subtracting 1 from the positive conflict times. If the positive punching times are still larger than 0, writing the positive punching information into the positive punching TDQ again; otherwise, the positive conflict request is abandoned, thereby controlling the number of positive conflict resending times.
The TDQ in the embodiment of the invention can be realized by using other queues with similar functions, and only needs to be provided with a first-in first-out and asynchronous trigger mechanism.
The invention realizes asynchronous and automatic initiation of multiple forward flushing calls and recording of forward flushing states (such as initial, forward flushing, failure or success) through a memory dump file mechanism and a first-in first-out queue mechanism of the IFA, automatically matches and initializes the transaction according to the transaction code through a transaction scheduling engine, and automatically loads IFA data for forward flushing.
