In order to solve the technical problem of large-area congestion of a transaction caused by parallel access of hot spot resources by a large number of transaction requests in the prior art, an embodiment of the present invention provides a transaction processing method, and fig. 1 is a schematic diagram of a flow of the transaction processing method in the embodiment of the present invention, as shown in fig. 1, the method includes:
step 101: obtaining a transaction request;
step 102: inputting the transaction information in the transaction request into a hot resource library, and searching whether the transaction request contains identification information of a hot resource; the hot spot resource library is established according to the incidence relation between a plurality of hot spot resources and identification information of the plurality of hot spot resources, and each hot spot resource corresponds to a maximum allowable concurrent number of transaction requests;
step 103: when the transaction request contains identification information of the hotspot resource, judging whether the number of the existing transaction requests of the hotspot resource is less than the maximum allowable concurrence number of the transaction requests of the hotspot resource;
step 104: and processing the transaction request when the number of the existing transaction requests of the hotspot resource is less than the maximum allowable concurrence number of the transaction requests of the hotspot resource.
As shown in fig. 1, an embodiment of the present invention is implemented by: obtaining a transaction request; inputting the transaction information in the transaction request into a hot resource library, and searching whether the transaction request contains identification information of a hot resource; when the transaction request contains identification information of the hotspot resource, judging whether the number of the existing transaction requests of the hotspot resource is less than the maximum allowable concurrence number of the transaction requests of the hotspot resource; when the transaction request contains the identification information of the hot spot resource, the transaction request is processed after the existing transaction request number of the hot spot resource is determined to be smaller than the maximum allowable concurrent number of the transaction request of the hot spot resource, so that the transaction request for accessing the hot spot resource is controlled in the transaction process, and the problem of large-area congestion of the transaction caused by the hot spot resource is avoided.
In step 101, in a large-scale host system, a transaction request may be an online transaction running on a CICS, and the CICS may perform unified scheduling on resources required in an online transaction processing process, where transaction information in the transaction request may include: transaction code, transaction account/card number, data to be accessed for the transaction, etc.
In step 102, the transaction information in the transaction request may be input into the hot resource library, and whether the transaction request includes identification information of a hot resource is searched, where the identification information of the hot resource may be a positioning hot account/card number or other information that may be associated with the hot resource, and a hot resource parameter configuration table and a hot resource parameter configuration file may be maintained for the transaction request according to whether the transaction request includes the identification information of the hot resource, and structures of the two are consistent.
Table 1 is a hotspot resource parameter configuration table, and as shown in table 1, the hotspot resource parameter configuration table may include: transaction code, whether to control transaction concurrency, maximum allowable concurrency number of transaction requests, position of hotspot resource in transaction request message and other parameters. Since each transaction request may involve multiple hot resources, each transaction request transaction may support synchronous, undifferentiated real-time monitoring of multiple hot resources, as shown in table 1, may support synchronous monitoring of five types of hot resources. It can be understood that the above table 1 is only an example of a hot resource parameter configuration table, and the hot resource parameter configuration table can be flexibly customized for different transaction requests according to actual transaction requirements during implementation, which is not limited by the invention.

Fig. 2 is a schematic diagram of a hotspot resource parameter configuration table/file update process in an embodiment of the present invention, as shown in fig. 2, when transaction information is newly added to a transaction request or needs to be modified, a corresponding hotspot resource parameter configuration table and a hotspot resource parameter configuration file may be modified in real time, which may be implemented by combining a DB2 database table and a VSAM file, the DB2 database may provide a visual operation interface for a user, implement real-time data update, provide operations of adding, deleting, checking, and changing with low maintenance cost, and after a user adds or changes transaction information through a maintenance interface and stores the transaction information, the corresponding VSAM file may be recorded and simultaneously validated, and the VSAM file is defined as a CMT mode, and may be directly loaded to a system memory of a CICS, thereby greatly reducing CPU consumption of online application access.
In one embodiment, before entering the transaction information in the transaction request into the hotspot resource database at step 102, the method further comprises:
establishing a hot spot resource library according to the following steps:
step 1021: for a plurality of hot spot resources, determining the identification information of each hot spot resource and the maximum allowable concurrent number of transaction requests;
step 1022: and establishing a hot spot resource library according to the incidence relation between each hot spot resource and the identification information of each hot spot resource and the maximum allowable concurrence number of the transaction requests of each hot spot resource.
During specific implementation, a plurality of hot resources and identification information corresponding to the hot resources can be determined according to daily monitoring data or historical transaction data, the maximum allowable concurrency number of transaction requests of the hot resources is set according to the daily monitoring data, and a hot resource library is established on the basis.
In one embodiment, step 103 may further comprise:
when the transaction request contains identification information of the hot spot resource, verifying the identification information of the hot spot resource in the transaction request;
and after the verification is passed, judging whether the number of the existing transaction requests of the hotspot resource is less than the maximum allowable concurrence number of the transaction requests of the hotspot resource.
In one embodiment, step 103 may further comprise: and processing the transaction request when the transaction request does not contain the identification information of the hotspot resource.
Fig. 3 is a schematic diagram of a transaction concurrency control flow in an embodiment of the present invention, as shown in fig. 3, in a specific implementation, step 103 may read a hot resource parameter configuration file of the transaction request after an online transaction is sent to a core bank system, and when a column of the hot resource parameter configuration file is "yes" to control whether to perform the transaction concurrency, may use an ENQ task control command of the CICS to implement the transaction concurrency control, including: extracting a resource name of a monitored hotspot resource from a transaction request message, verifying the validity of the resource name, reading the maximum allowable concurrency number of the transaction request from a hotspot resource parameter configuration file by using a task control command (ENQ) of a CICS (common information system), taking a combination mode of the hotspot resource name and a serial number (the value range of the serial number is 1-the maximum allowable concurrency number of the transaction request) as an object locked when the ENQ carries out single-line control, and judging whether the existing transaction request number of the hotspot resource is smaller than the maximum allowable concurrency number of the transaction request of the hotspot resource by judging whether the lockable object exists at present.
It should be noted that the ENQ locking/releasing object set is equivalent to a virtual resource pool, the locking of the resource records the occurrence of the transaction, the transaction is ended, the resource is automatically released, and the capacity of the virtual resource pool is determined by the maximum allowable concurrence number of the transaction requests of the hot resource, so as to achieve the purpose of counting the current existing transaction requests.
It should be noted that the verification of the validity of the hotspot resource name is to avoid unnecessary transaction rejection caused by parameter configuration errors, message serial bits, and other factors.
The ENQ control command is as follows:
EXEC CICS ENQ RESOURCE(WS-ENQNAME)；
LENGTH(LENGTH OF WS-ENQNAME)；
RESP(WS-RESP)；
NOSUSPEND；
END-EXEC。
in specific implementation, when the column of whether to perform transaction concurrency control in the hotspot resource parameter configuration file is "no", it indicates that the transaction request does not need to access hotspot resources, and does not need to perform transaction concurrency control, and a service processing program of the transaction request can be directly performed.
In one embodiment, step 104 may further include:
and rejecting the transaction request when the number of the existing transaction requests of the hotspot resource is greater than or equal to the maximum allowable concurrency number of the transaction requests of the hotspot resource.
In one embodiment, step 104 may further include:
when the number of the existing transaction requests of the hotspot resource is more than or equal to the maximum allowable concurrency number of the transaction requests of the hotspot resource, caching the transaction requests;
judging whether the existing transaction request number of the hotspot resource is smaller than the maximum allowable concurrent number of the transaction requests of the hotspot resource again after the preset interval duration;
if the existing transaction request number of the hotspot resource after re-judgment is smaller than the maximum allowable concurrent number of the transaction requests of the hotspot resource, processing the transaction request;
and if the existing transaction request number of the hotspot resource after re-judgment is larger than or equal to the maximum allowable concurrent number of the transaction requests of the hotspot resource, rejecting the transaction request.
In specific implementation, as shown in fig. 3, in step 104, it may be tried to lock a counting resource in the virtual resource pool of the hot resource, and when there is a free resource in the virtual resource pool of the hot resource that can be used for recording the transaction request, the counting resource is successfully locked, which indicates that the number of existing transaction requests of the hot resource is less than the maximum allowable concurrence number of transaction requests of the hot resource, and online transaction processing may be performed; when the number of the existing transaction requests of the hotspot resource is larger than or equal to the maximum allowable concurrency number of the transaction requests of the hotspot resource, no lockable resource exists in a virtual resource pool of the hotspot resource, the resource locking is counted to fail, when the locking fails for the first time, the locking can be retried after a preset interval duration, if the locking succeeds, online transaction processing is carried out, and if the locking fails, the transaction request is rejected. It should be noted that, when the first locking fails, the locking is retried after a preset interval duration, so that the probability of transaction rejection can be effectively reduced.
