In order to obtain accurate information of abnormal transactions, in another embodiment of the present application, the locating the abnormal transaction according to the target serial number to determine the information of the abnormal transaction includes: analyzing the global service tracking number and obtaining a first analysis result, wherein the first analysis result at least comprises a timestamp, a first system number, a first transaction instance serial number and a serial number, the timestamp is the timestamp corresponding to the abnormal transaction when the transaction is initiated, the first system number is an identification code corresponding to an original initiator system of the abnormal transaction, the first transaction instance serial number is the identification code of a machine where the transaction instance corresponding to the abnormal transaction is located, and the serial number is a circularly-increased serial number generated for the original initiator system when the abnormal transaction is initiated; and determining the information of the abnormal transaction according to the first analysis result. The global service tracking number is generated by the trigger point, and the consistency lasts until the time is completely finished, so that the information of the abnormal transaction is recorded in the global service tracking number.

The global service tracking number may be used as a database primary key in the system, the length of the primary key is required to be not too long for the primary key of the database, and in addition, considering that the global service tracking number has more components, in a specific embodiment of the present application, the global service tracking number is set to be 32 bits. The composition of the global service tracking number is shown in table one:

watch 1

The time stamp is as follows: generated by acquiring the local system time, belongs to the technical field.

The system number is as follows: all systems are organized according to the division of business functions, which is a code with business attributes, which is composed of 7 bits, which is derived from a unified standard. For example, the deposit system uses "1111111" and the money transfer system uses "2222222". The system number in the usage, global traffic tracking number is generated by the transaction initiator.

Transaction instance number above: this component belongs to the technology field. The generation flow is as shown in fig. 3, when the transaction instance serial number is initiated to be acquired, the transaction instance serial number is acquired from a local environment variable, the environment variable is an environment parameter configured in the server, if the environment variable exists, the environment variable is directly returned, if the environment variable does not exist, the environment variable is acquired from a starting parameter of the system, if the environment variable exists, the configuration of the transaction instance serial number is directly returned, and if the environment variable does not exist, the transaction instance serial number is generated through a local default implementation algorithm. The transaction instance sequence number in the global transaction tracking number is generated by the transaction initiator.

The generation of the sequence number: in the present application, the serial numbers are recycled, and the flow of their generation is shown in fig. 4. The serial number is self-increased by adopting Java native AtomicInteger, whether the result obtained after self-increasing is larger than 999999 is judged, if so, the serial number is set to be 1 and the character string formatting is carried out, and if not, the obtained result is carried out the character string formatting to generate the final serial number.

And splicing the generated 14-bit timestamp, the 7-bit system code, the 5-bit initiated transaction instance serial number and the 6-bit sequence number to obtain the generated global service tracking number. As shown in FIG. 5, assume that there is a transaction, and the transaction link is shown in the following figure. The system A is used as a transaction initiator, the system A generates a global business tracking number of the transaction, and the system B and the system C can not generate the global business tracking number again. Each inter-system call in a transaction sends a global transaction tracking number to a downstream system.

In another embodiment of the present application, as shown in fig. 6, before the locating the abnormal transaction according to the target serial number to determine the information of the abnormal transaction, the method further includes: acquiring an MAC address corresponding to a machine where an original transaction instance corresponding to the abnormal transaction is located; calculating a hash value corresponding to the MAC address, and performing a modulus operation on the hash value to obtain a modulus result; and carrying out zero filling operation on the modulus result to obtain the first transaction instance serial number. In this embodiment, a hash value is calculated by using the MAC address of the machine where the original transaction instance is located, then a modulo operation is performed on the hash value, and finally a zero padding operation is performed on the result of the modulo operation, thereby obtaining an accurate serial number of the first transaction instance.

For example, if the transaction instance number is 5 bits, then 99999(5 9) is modulo, and if the transaction instance number is 6 bits, then 999999(6 9) is modulo. And finally, performing character string formatting (namely zero padding operation) on the modulus result to complete the generation of the transaction instance serial number.

In addition, the method for determining the serial number of the first transaction instance further comprises the steps of obtaining configuration parameters of service starting and obtaining environment variable configuration.

In another embodiment of the present application, the positioning the abnormal transaction according to the target serial number to determine a calling system corresponding to the abnormal transaction when an abnormality occurs in a transaction link includes: acquiring a target sub-transaction serial number in a plurality of sub-transaction serial numbers contained in the target serial number, wherein the target sub-transaction serial number is a current sub-transaction serial number generated in the transaction process of the abnormal transaction; analyzing the target sub-transaction serial number and obtaining a second analysis result, wherein the second analysis result at least comprises a second system number, a second transaction instance serial number and a latest transaction arrangement number, the second system number is an identification code corresponding to the current calling initiator system corresponding to the abnormal transaction, the second transaction instance serial number is an identification code of a machine where the transaction instance corresponding to the abnormal transaction generated by the current calling initiator system is located, and the latest transaction arrangement number represents a call link to the system in the current calling process from two dimensions, namely a horizontal dimension and a longitudinal dimension; and determining a corresponding calling system when the abnormal transaction is abnormal in the transaction link according to the second analysis result. In this embodiment, the target sub-transaction serial number needs to be first obtained to obtain a second system number, a second transaction instance serial number, and a latest transaction arrangement number, and the transaction link of the call initiation system and the call process of the abnormal transaction can be located through the second system number, the second transaction instance serial number, and the latest transaction arrangement number, so that the call system in which the abnormality occurs in the complex link can be quickly located.

The target sub-transaction serial number includes a second system number, a second transaction instance serial number, and a latest transaction arrangement number. The target sub-transaction serial number is mainly used for identifying each calling sub-branch of one transaction. The composition of the target sub-transaction sequence number is shown in table two:

watch two

The second system number is different from the system number in the global service tracking number in that the second system number is generated by the current call initiator system.

The generation method of the transaction instance serial number is consistent with the method of the global service tracking number, but the difference is that the transaction instance serial number is generated by a calling initiator system.

The latest transaction arrangement number is composed of letters and numbers. The latest transaction arrangement number has 20 bits in total, which represents that the maximum support of the transaction level number is 20 layers, and the character value range of each bit in the latest transaction arrangement number is 1-9, A-Z, which represents that the maximum support of the same-level transaction instance number is 35. The latest transaction arrangement number represents a transaction calling link from two dimensions of horizontal and vertical, and is transmitted backwards along the transaction link. The initial value of the latest transaction serial number is all 0, and the latest transaction serial number can be subjected to layer-ascending or ascending logic every time system calling occurs on a transaction link.

In yet another embodiment of the present application, before the abnormal transaction is located according to the target serial number to determine a corresponding calling system when the abnormal transaction is abnormal in a transaction link, the method includes: acquiring current system call information corresponding to the abnormal transaction in the transaction link, wherein the current system call information at least comprises information of the current call initiator system corresponding to the abnormal transaction and information of the current called system; and generating the target sub-transaction serial number according to the current system calling information. In this embodiment, the target sub-transaction serial number is generated according to the call information of the current system, so that the system with abnormal transaction can be located according to the target sub-transaction serial number, and the call system with abnormal transaction can be located more quickly.

In a specific embodiment of the present application, after receiving a message transmitted by an upstream system, an offspring transaction serial number in the message is stored in a customized context, and the customized context is implemented using a thread class native to JAVA. Thread local is a storage class inside a thread, and can store data in a specified thread, and after the data is stored, only the specified thread can obtain the stored data. Thread local has a thread isolation effect by using a single memory space for each thread, and the corresponding value can be obtained only in the thread, and the desired value cannot be accessed outside the thread. Therefore, the current thread for transaction can acquire the sub-transaction serial number transmitted from the upstream system to the system through the customized context.

And creating a data structure of the stack in the custom context, wherein the data structure is used for storing the newly generated sub-transaction serial number and is marked as a sub-transaction serial number stack. The number of the sub-transaction serial numbers stored at the beginning of the stack is 0, the sub-transaction serial numbers are pressed into the stack every time a new sub-transaction serial number is generated, and the elements at the top of the stack are the latest sub-transaction serial numbers forever. It should be noted that there are two attributes in the custom context for storing the sub-transaction serial number, and the difference between the two attributes, which are denoted as substxno and substxnotack in the present application, is shown in table three below.

Watch III

When the layer upgrading of the sub-transaction sequence numbers is needed, whether the number of elements in the sub-transaction sequence number stack subTxNOStack is 0 or not is mainly used for judging, if the number of the elements in the sub-transaction sequence number stack subTxNOStack is 0, the generation of the sub-transaction sequence numbers is not performed by the current system, and the logic of layer upgrading is performed when the current system calls the external system for the first time. When the layer is upgraded, the sub-transaction sequence number subTxNo transmitted to the system by the upstream system needs to be taken out from the custom context, the logic of the layer upgrading of the sub-transaction sequence number in the section is completed by taking the sub-transaction sequence number subTxNo as a reference, and finally the newly generated sub-transaction sequence number is pressed into a sub-transaction sequence number stack subTxNoStack of the custom context.

When the sub-transaction sequence number rises, the judgment is also carried out according to whether the number of elements in the sub-transaction sequence number stack subTxNOStack is 0, if not, the generation of the sub-transaction sequence number is shown by the current system, and the logic of rising is carried out when the current system is not the first calling external system. When the sub-transaction sequence number is increased, the sub-transaction sequence number at the top of the stack needs to be obtained from the sub-transaction sequence number stack subTxNOStack, the logic of increasing the sub-transaction sequence number in the section is completed by taking the sub-transaction sequence number as a reference, and finally, the newly generated sub-transaction sequence number is pressed into the sub-transaction sequence number stack subTxNOStack.

And when the caller system needs to generate the sub-transaction serial number, returning the stack top element of the sub-transaction serial number stack with the self-defined context to the system.

In another embodiment of the present application, the generating the target sub-transaction serial number according to the current system call information includes: acquiring an identification code corresponding to the current calling initiator system, and determining the identification code as a prefix of the target sub-transaction serial number; generating the target sub-transaction serial number to obtain a transaction instance serial number; determining the current system in the transaction link level and determining the level number corresponding to the level; arranging the prefixes and the hierarchy numbers in sequence, and determining characters except the prefixes and the hierarchy numbers to be 0 so as to generate a reference serial number corresponding to the target sub-transaction serial number; acquiring the calling condition of the current calling initiator system for calling the current called system, and adjusting the reference serial number according to the calling condition; and determining the adjusted reference serial number as the target sub-transaction serial number. In this embodiment, a prefix of the calling and originating system and a hierarchical number of the exchange are determined, then the number of characters in the target sub-transaction serial number is determined, the prefix and the hierarchical number are arranged in sequence, and the characters except the prefix and the hierarchical number are determined to be 0, so that the target sub-transaction serial number is generated.

The process for generating the target sub-transaction serial number specifically comprises the following steps: taking the transaction link shown in fig. 7 as an example, the link focuses on the generation flow of the latest transaction arrangement number, and the system number and the transaction instance number in the sub-transaction number are represented by using corresponding placeholders in a unified manner, for example, the system a uses the letter "a" to represent the system number and the transaction instance number, the system B uses the letter "B" to represent the system number and the transaction instance number, and so on.

(1) The system a generates the first sub-transaction serial number of the transaction as the transaction initiator, and the sub-transaction serial number is "a 1000000000000000000". The system A is used as a transaction initiator, the transaction level number of the system A is 1, so that the first bit in the corresponding latest transaction arrangement number is 1, and the last 19 bits are 0;

(2) system a first calls system B, then system C, and then system D.

At this time, three new sub-transaction serial numbers need to be generated to represent the three call branches, and the system number and the transaction instance serial number in the three sub-transaction serial numbers are generated by the system a, so the prefixes of the sub-transaction serial numbers are all a. For the first time, the system A calls the system B, which belongs to the external system called by the system A for the first time, so that the logic of upgrading is needed, and the sub-transaction serial number obtained by taking the first sub-transaction serial number 'A1000000000000000000' as the reference according to the logic of upgrading is 'A110000000000000'; secondly, the system A calls the system C, the non-system A calls the external system for the first time, so that the ascending logic is needed, the above one sub-transaction serial number 'A1100000000000000000' is used as a reference, and the obtained sub-transaction serial number is 'A120000000000000' according to the ascending logic; thirdly, the system A calls the system D, the non-system A calls the external system for the first time, so that the ascending logic is needed, the sub-transaction serial number is 'A13000000000000000000000' according to the ascending logic with the above one sub-transaction serial number 'A1200000000000000000' as the reference.

(3) System B calls system E and system B calls system F. At this time, two new sub-transaction serial numbers need to be generated to represent the two call sub-branches, and the system number and the transaction instance serial number in the two sub-transaction serial numbers are generated by the system B. For the first time, the system B calls the system E, which belongs to the external system called by the system B for the first time, so that the logic of ascending a layer is needed, the previous sub-transaction serial number 'A110000000000000' is taken as a reference, and the generated sub-transaction serial number is 'B111000000000000'; secondly, the system B calls the system F, the non-system B calls the external system for the first time, and therefore the ascending logic is required, and the sub-transaction serial number obtained according to the ascending logic with the previous sub-transaction serial number "B11100000000000000000000" as the reference.

(4) System D calls system G. At this time, a new sub-transaction serial number is generated to represent the call sub-branch, and the system number and the transaction instance serial number of the sub-transaction serial number are generated by the system D. The system D calls the system G, belongs to the external system called by the system D for the first time, therefore, the logic of ascending the layer is needed, the sub-transaction serial number is 'D1310000000000000000' according to the logic of ascending the layer, and the obtained sub-transaction serial number is 'A1300000000000000000'. So far, the latest transaction arrangement number generation process of the transaction link is completed.

Taking the generated target sub-transaction serial number "D1310000000000000000" as an example, it can be known that the system caller is system D; in the latest transaction arrangement number of the last 20 digits, 3 non-0 characters are totally contained, which indicates that the transaction level number of the current system in the transaction link is 3; and finding the position of the latest transaction arrangement number, in which the character 0 appears from left to right, and recording the position as pos, wherein pos is subtracted by one, and the corresponding character is '1', which indicates that the current system is the first system called by the system D.
