[0049] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described below in detail with reference to the embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0050] The technical solutions provided by the embodiments of the present application will be described below in detail with reference to the accompanying drawings.

[0051] In the prior art, when a new version of a clearing application is released, two sets of clearing logic need to be implemented in the new version of the clearing application, and the clearing results of the two sets of logic are checked to evaluate the clearing accuracy of the new version of the clearing application according to the checking result. However, this method at least has the following problems:

[0052] 1) The developer needs to maintain two sets of logic, and the workload is doubled during iterative development;

[0053] 2) There may be common code modules in the two sets of logic. If the common code modules are modified, a software system vulnerability or defect may occur, and the clearing results of the two sets of logic may be incorrect, but the clearing results of the two sets of logic are consistent, so that the checking result is passed, and then the new version of the clearing application is released to each data center, resulting in a large impact range of the problems existing in the new version of the clearing application.

[0054] Based on this, the embodiments of the present application provide a clearing application release method, which is executed by a clearing application server of a first data center, as shown in Figure 1 FIG. 1 is a structural schematic diagram of an electronic device according to an embodiment of the present application.

[0055] Step S110, obtaining a library-level clearing result of a transaction database of a first data center, and obtaining a library-level clearing result of a transaction database of a second data center associated with the transaction database of the first data center, wherein the first data center is deployed with a new version of a clearing application, and the second data center is deployed with an old version of the clearing application.

[0056] The clearing application publishing method of the embodiments of the present application can be executed by a clearing application server of a first data center where a new version of the clearing application is located. When publishing the new version of the clearing application, the library-level clearing result of a transaction database of the first data center needs to be obtained first. The transaction database herein can be understood as any one of the transaction databases in the first data center, or can be designated according to actual clearing task requirements, that is, the clearing application publishing method of the embodiments of the present application needs to clear a certain transaction database in the first data center first.

[0057] In addition, the library-level clearing result of a transaction database of a second data center associated with the transaction database of the first data center also needs to be obtained. The "association" herein can be understood as that the transaction data in the transaction database of the first data center is synchronized to the second data center in an asynchronous synchronization manner, that is, the second data center provides disaster recovery capability for the transaction data in the first data center. In addition, the first data center is deployed with the new version of the clearing application to be published, while the second data center is still deployed with the old version of the clearing application. Therefore, in the case that the transaction database data in the second data center is synchronized normally, the library-level clearing result of the transaction database corresponding to the second data center can be used as a basis for judging the accuracy of the library-level clearing result obtained by the new version of the clearing application.

[0058] Step S120, the library-level clearing result of the transaction database of the first data center is compared with the library-level clearing result of the transaction database of the second data center.

[0059] After obtaining the library-level clearing result of the transaction database of the first data center and the library-level clearing result of the transaction database of the associated second data center, the two database-level clearing results need to be compared with each other, so as to obtain a consistent comparison result or an inconsistent library-level comparison result. If the library-level comparison result is consistent, it indicates that the clearing result of the new version of the clearing application for the transaction database of the first data center is accurate. If the library-level comparison result is inconsistent, it indicates that the clearing result of the new version of the clearing application for the transaction database of the first data center is inaccurate, so that the subsequent application publishing cannot be directly performed.

[0060] Step S130, in the case that the library-level comparison result is consistent, the data center-level clearing result of the first data center and the data center-level clearing result of the second data center corresponding to the first data center are obtained.

[0061] If the library-level check result is consistent, it indicates that the library-level clearing result of the new version of the clearing application for the transaction database of the first data center is accurate, and then the data center-level clearing result of the first data center can be further obtained. The data center-level clearing result herein can be understood as the clearing result of all transaction databases in the first data center where the new version of the clearing application is located.

[0062] In addition, the data center-level clearing result of a second data center corresponding to the first data center also needs to be obtained. The transaction data in the second data center obtained by the embodiment of the application is obtained synchronously with the transaction data in the first data center. Therefore, the data center-level clearing result of the second data center can be obtained as a basis for subsequently judging the accuracy of the data center-level clearing result obtained by the new version of the clearing application.

[0063] In step S140, the data center-level clearing result of the first data center is checked with the data center-level clearing result of the second data center, so as to determine whether the new version of the clearing application is released at the data center level according to the center-level check result.

[0064] After obtaining the data center-level clearing result of the first data center and the data center-level clearing result of the second data center, the two data center-level clearing results need to be checked with each other, so as to obtain a consistent check result or an inconsistent center-level check result. If the center-level check result is consistent, it indicates that the clearing result of the new version of the clearing application for the entire first data center is also accurate. If the center-level check result is inconsistent, it indicates that the clearing result of the new version of the clearing application for the first data center is inaccurate, and then the new version of the clearing application cannot be directly released to other data centers.

[0065] It should be noted that the first data center and the second data center in the embodiment of the application are only specific limitations for mutual distinction, and the two data centers are independent and equal to each other. In essence, they are only a synchronous relationship on the transaction database. Therefore, all operations performed by the first data center in the application can also be applied to any second data center.

[0066] The cleanup application deployment method in this application first uses the new version of the cleanup application to perform database-level cleanup processing on the database of a data center. If the cleanup result is correct, the new version of the cleanup application is then used to perform data center-level cleanup processing on all databases in the data center. If the cleanup result is correct, the new version of the cleanup application can be deployed to all data centers. That is, by checking at the database level and then at the data center level, problems with the new version of the cleanup application can be discovered in a timely and accurate manner, thereby minimizing its impact and avoiding greater impact on business.

[0067] In one embodiment of this application, the transaction database of the first data center includes a local database of the first data center and / or an associated database of the second data center deployed in the first data center; the transaction database of the second data center includes a local database of the second data center and / or an associated database of the first data center deployed in the second data center; the associated database includes a local database and a remote database corresponding to the local database.

[0068] To improve data center disaster recovery capabilities and ensure transaction stability and security, a primary / backup data center model can be adopted. Specifically, the primary data center handles data reading and writing, while the backup data center performs redundant data backup. The primary data center periodically synchronizes data to the backup data center asynchronously. Backup data centers can be further divided into local and remote data centers. "Local" means both data centers are within the same region, such as IDC1 and IDC2 in city A. "Remote" means the two data centers are not in the same region, such as IDC1 in city A and IDC3 in city B. Figure 2 As shown, a schematic diagram of a data synchronization relationship between data centers is provided in an embodiment of this application.

[0069] Based on this, the transaction database in the first data center of this application embodiment may include a local database in the first data center and a local database or a remote database deployed in the first data center by the second data center. Correspondingly, the transaction database in the second data center may also include a local database in the second data center and a local database or a remote database deployed in the second data center by the first data center or other data centers.

[0070] Of course, it needs to be pointed out that the transaction database in the first data center and the transaction database in the second data center are not in a one-to-one correspondence, and the first data center corresponds to a local data center and a remote data center, and the local data center and the remote data center can be regarded as the second data center defined in the embodiments of the application.

[0071] For example, assuming that there is the IDC01, the local IDC02 corresponding to the IDC01 and the remote IDC03 corresponding to the IDC01, the transaction databases in the three IDCs can be in the form of Table 1 as follows:

[0072] Table 1

[0073] IDC01 IDC02 IDC03 Local database of IDC01 Local database of IDC02 Local database of IDC03 Local database of IDC02 Local database of IDC01 Local database of IDC05 Remote database of IDC03 Remote database of IDC04 Remote database of IDC01

[0074] Based on Table 1, in the case that the data synchronization of the local database and the remote database is normal, if it is intended to check the clearing result of the local database of the IDC01, the clearing result of the local database of the IDC01 can be found in the local IDC02 corresponding to the IDC01, and the clearing result of the local database of the IDC01 is checked with the clearing result of the local database of the IDC01. If the check is inconsistent, it can be considered that the clearing result is inaccurate under normal circumstances. Of course, in order to further determine, the clearing result of the remote database of the IDC01 corresponding to the IDC01 can also be found in the remote IDC03, and the clearing result of the local database of the IDC01 is checked with the clearing result of the remote database of the IDC01. If the check is still inconsistent, it can be determined that the clearing result of the local database of the IDC01 is inaccurate. Similarly, if it is intended to check the clearing result of the local database of the IDC02 or the clearing result of the remote database of the IDC03, the clearing result of the corresponding database can also be obtained in the corresponding data center, and details are not described herein. Of course, in addition to the above two-by-two checking method, the clearing results of the local database, the local database and the remote database can also be checked at the same time.

[0075] That is, in the actual application scenario, the database supported by the comparison processing of the first data center of the application is not limited to the local database in the first data center, and the local database and the remote database in other data centers in the first data center are also supported. If the local database or the remote database is taken as the benchmark, the clearing result of the data center where the local database corresponding to the local database or the remote database is located can be found reversely and compared.

[0076] In one embodiment of this application, obtaining the database-level clearing result of the transaction database of the first data center includes: receiving a database-level clearing task for the transaction database of the first data center; determining a target transaction database in the first data center based on the database-level clearing task for the transaction database of the first data center; clearing the transaction data of the target transaction database to obtain the database-level clearing result of the transaction database of the first data center.

[0077] In this embodiment of the application, when obtaining the database-level clearing results of the transaction database of the first data center, the database-level clearing task issued by the timed component can be received first. As mentioned above, the first data center may include the local database of the first data center, and may also include the same-city database and the remote database of the second data center in the first data center. Therefore, the database-level clearing task here may specifically include the database-level clearing task of the local database, and may also include the database-level clearing task of the same-city database and the remote database. Different types of database-level clearing tasks can be issued in advance according to actual needs.

[0078] When executing a database-level clearing task for the transaction database in the first data center, the transaction data of the transaction database can be obtained and cleared first according to the database-level clearing task, thereby obtaining the database-level clearing result for the transaction database. Similarly, when executing a database-level clearing task for the corresponding local and remote databases in the first data center in the second data center, the transaction data of the local and remote databases in the first data center can be obtained and cleared first according to the database-level clearing task, thereby obtaining the database-level clearing result for the local and remote databases in the first data center. The specific clearing logic can be flexibly set by those skilled in the art according to actual needs, and is not specifically limited here.

[0079] The specific transaction database in the first data center to be cleared can be specified in the clearing task. Once the transaction database in the first data center is determined, its corresponding same-city database and cross-regional database in other data centers will also be determined.

[0080] In one embodiment of this application, the first data center includes multiple transaction databases, and obtaining the data center-level clearing result of the first data center includes: receiving the data center-level clearing task of the first data center; clearing each transaction database of the first data center according to the data center-level clearing task of the first data center to obtain the database-level clearing result of each transaction database of the first data center; and merging the database-level clearing results of each transaction database to obtain the data center-level clearing result of the first data center.

[0081] Likewise, when obtaining the data center level clearing result of the first data center, the embodiment of the present application can first receive the data center level clearing task issued by the timing component. The data center level clearing task refers to the task of clearing all transaction databases in the first data center. The issuance of the task mainly depends on the checking result of the library level clearing result in the first data center in the foregoing embodiment.

[0082] When performing the data center level clearing task of the first data center, the transaction data of all local databases under the first data center can be obtained first, and then the new version of the clearing application deployed in the first data center is used to clear respectively, so as to obtain the library level clearing result of each transaction database in the first data center. Finally, the library level clearing result of each transaction database is obtained.

[0083] Taking the first data center IDC01 as an example, the IDC01 can have multiple transaction databases, including transaction database 001, transaction database 002 and transaction database 003. When performing the data center level clearing processing, the transaction data of the transaction databases 001, 002 and 003 can be obtained first, and then the transaction data of the transaction databases 001, 002 and 003 is cleared respectively to obtain the library level clearing result of the transaction databases 001, 002 and 003. Then, the library level clearing result of the transaction databases 001, 002 and 003 is merged in the dimension of IDC01 to obtain the data center level clearing result of IDC01.

[0084] It should be noted that the foregoing embodiment only takes the implementation logic of the clearing application of the first data center as an example for description, and in actual application scenarios, each IDC has a set of clearing application. Each set of clearing application can issue the library level clearing task of the local database of the IDC and the library level clearing task of the local database of the IDC in the same city or different places of other IDCs. When each type of clearing task completes the clearing of all transaction databases, the clearing application merges all the library level clearing results into the IDC level clearing result.

[0085] The issuance of the library level clearing task of the transaction database in the second data center in the foregoing embodiment can be before the issuance of the library level clearing task of the transaction database in the first data center. The issuance of the data center level clearing task of the second data center can be before the issuance of the data center level clearing task of the first data center. Of course, the issuance can also be simultaneous, as long as the library level clearing result and the data center level clearing result in the second data center can be obtained in time.

[0086] In an embodiment of the present application, the library-level clearing results each include an element identifier and an element value, and the library-level checking of the library-level clearing results of the transaction database of the first data center with the library-level clearing results of the transaction database of the second data center includes: checking the element identifier and the element value of the transaction database of the first data center with the element identifier and the element value of the transaction database of the second data center respectively; if the element identifier of the transaction database of the first data center is consistent with the element identifier of the transaction database of the second data center, and the element value of the transaction database of the first data center is consistent with the element value of the transaction database of the second data center, then the library-level checking result is consistent; otherwise, the library-level checking result is inconsistent.

[0087] The library-level clearing result can specifically include an element identifier and an element value, etc. The element identifier can include various fields such as an institution code, a clearing business type, a transaction amount, a transaction number, etc., and the element value is a specific value corresponding to each element identifier field. When comparing the clearing results, the element identifiers can be compared first to see if they are consistent. If all the element identifiers are consistent, then the element values corresponding to each element identifier are further compared to see if they are consistent. If they are consistent, then the library-level checking result is consistent; otherwise, the library-level checking result is inconsistent.

[0088] For example, assume that the library-level clearing result of the transaction database of the first data center is shown in Table 1 below, and the library-level clearing result of the associated database is shown in Table 2 below. As can be seen, both Table 1 and Table 2 include three fields of an institution code, a clearing business type and a transaction amount, but the transaction amount corresponding to the institution code 0002 and the clearing business type T1 is different, so it can be concluded that the library-level clearing result of the transaction database of the first data center is inconsistent with the library-level clearing result of the corresponding transaction database of the second data center.

[0089] Table 1

[0090] Institution code Clearing service type Transaction amount 1 0001 T1 1 million 2 0002 T1 1.5 million ……

[0091] Table 2

[0092] Institution code Clearing service type Transaction amount 1 0001 T1 1 million 2 0002 T1 1.49 million ……

[0093] In an embodiment of the present application, the data center level clearing result of the first data center and the data center level clearing result of the second data center are compared at the data center level, and the comparison result is determined according to the comparison result at the data center level. The comparison at the data center level includes: comparing the element identifier and the element value of the first data center with the element identifier and the element value of the second data center respectively; if the element identifier of the first data center is consistent with the element identifier of the second data center, and the element value of the first data center is consistent with the element value of the second data center, then the comparison result at the data center level is consistent; otherwise, the comparison result at the data center level is inconsistent.

[0094] Since the data center level clearing result is obtained by summarizing the library level clearing result, the comparison logic of the data center level clearing result is similar to that of the library level clearing result, that is, the element identifier in the data center level clearing result of the first data center is compared with the element identifier in the data center level clearing result of the second data center respectively, if all the element identifiers are consistent, then the element value corresponding to each element identifier is further compared, if they are consistent, then the comparison result at the data center level is consistent, otherwise, the comparison result at the data center level is inconsistent.

[0095] It should be noted that in the above embodiment, the clearing application in the second data center is an old version of the clearing application in the same city data center and the clearing application in the remote data center, that is, the clearing application has been normally running on line for a period of time, and in the case that the data synchronization in the same city data center and the remote data center is normal, the library level clearing result of the second data center and the data center level clearing result of the second data center obtained thereby can be considered as accurate clearing results, and thus can be used as the comparison basis in the above embodiment, so as to ensure that a more accurate comparison result can be obtained, so that when the new version of the clearing application has a problem, the influence range thereof can be controlled to the minimum range, and greater influence can be avoided.

[0096] In an embodiment of the present application, the data center level clearing result of the first data center and the data center level clearing result of the second data center are compared at the data center level, and the comparison result is determined according to the comparison result at the data center level. The comparison at the data center level includes: comparing the element identifier and the element value of the first data center with the element identifier and the element value of the second data center respectively; if the element identifier of the first data center is consistent with the element identifier of the second data center, and the element value of the first data center is consistent with the element value of the second data center, then the comparison result at the data center level is consistent; otherwise, the comparison result at the data center level is inconsistent.

[0097] If the data center level clearing result of the first data center is consistent with the corresponding data center level clearing result of the second data center, it indicates that the new version of the clearing application can obtain accurate clearing result, and thus can be deployed to other data centers. If the checking is inconsistent, it indicates that the clearing result obtained by the new version of the clearing application is not accurate enough and cannot be directly released to other data centers.

[0098] The above checking logic can obtain more accurate checking result, and thus can ensure that the new version of the clearing application can control the impact to the minimum range when the clearing is wrong.

[0099] In an embodiment of the present application, after the library level clearing result of the transaction database of the first data center is checked with the library level clearing result of the transaction database of the second data center, the method further comprises: if the library level checking result is consistent, storing the library level clearing result of the transaction database of the first data center into a library level clearing result table; after the data center level clearing result of the first data center is checked with the data center level clearing result of the second data center, the method further comprises: if the data center level checking result is consistent, storing the data center level clearing result of the first data center into a data center level clearing result table; wherein the library level clearing result table and the data center level clearing result table are stored in the clearing database of the first data center.

[0100] In order to uniformly manage the clearing result of the database, the first data center and the second data center of the embodiments of the present application can respectively deploy a clearing database for uniformly storing the checking error-free clearing result as the basis for providing externally.

[0101] Taking the clearing database of the first data center as an example, according to different checking levels, the clearing database of the first data center can include a library level clearing result table and a data center level clearing result table. If the library level clearing result of the first data center passes the checking, the library level clearing result of the first data center can be stored into the library level clearing result table of the first data center. If the data center level clearing result of the first data center passes the checking, the data center level clearing result of the first data center can be stored into the data center level clearing result table of the first data center.

[0102] In an embodiment of the present application, after the data center level clearing result of the first data center is stored into the data center level clearing result table, the method further comprises: receiving a clearing result obtaining request; and according to the clearing result obtaining request, obtaining and returning the library level clearing result and / or the data center level clearing result from the clearing database of the first data center.

[0103] In actual application scenarios, the clearing result obtained by the clearing application can be provided to relevant personnel for checking, and therefore, after the checking of the clearing result is completed, the clearing result obtaining request can be received, the clearing result of the target database or the target data center that the relevant personnel want to obtain can be determined according to the clearing result obtaining request, and the corresponding clearing result in the clearing database in the above embodiment can be queried and returned.

[0104] When the clearing result is provided to the outside, the clearing result in the clearing database of the data center corresponding to the clearing result obtaining request is preferentially provided, so that the resource consumption of accessing the database across the data centers is saved.

[0105] It should be noted that, in the above embodiment, the checking of the clearing result of the clearing application is performed at the database level and the data center level, and the checking manner at each level can be flexibly adjusted according to actual conditions, for example, at the database level, the clearing results of two or more transaction databases can be checked, at the data center level, the clearing results of the transaction databases under two or more data centers can be checked, and the like, so as to further improve the accuracy of the checking of the clearing result of the clearing application.

[0106] In order to facilitate the understanding of the embodiments of the present application, as shown in Figure 3 a clearing application publishing process schematic diagram in the embodiments of the present application is provided, and the checking logic of the first data center is taken as an example for description. First, the new version of the clearing application is published to the first data center, then the library-level clearing task of the first data center is received, the transaction data corresponding to the transaction database is obtained according to the library-level clearing task of the first data center, and the transaction data is cleared to obtain the library-level clearing result of the first data center, then the library-level clearing result of the second data center corresponding to the first data center is obtained, and the two are checked.

[0107] If the library-level checking result is consistent, the new version of the clearing application can be used to receive the data center-level clearing task of the first data center, the transaction data of all databases in the first data center is obtained according to the data center-level clearing task of the first data center, and the transaction data is cleared to obtain the data center-level clearing result of the first data center, then the data center-level clearing result of the second data center corresponding to the first data center is obtained, and the two are checked. If the center-level checking result is consistent, the new version of the clearing application can be published to other data centers, and if the center-level checking result is inconsistent, the new version of the clearing application cannot be directly published to other data centers.
