Description
Technical Field
The present disclosure relates to the field of internet technologies, and in particular, to a system switching method, apparatus, device, medium, and program product.
Background
At present, a core bank system of a large-scale bank is mainly based on a host technology and adopts a host system with a centralized architecture. The host system is a core platform for processing business data in the system, has strong computing power and high stability, can process millions of transactions per minute, and can meet the large-scale business processing requirements of large-scale banks. However, the coupling degree between the host system modules is too high, one of the functional modules is upgraded, and the other modules need to be upgraded and deployed at the same time. And the host system needs to perform all operations, which results in slow response speed when there are many terminals. When the terminal users have different needs, the programs and resources of each user need to be configured separately, which is not efficient. The existing core bank system is basically constructed by adopting an IBM large-scale host as a foundation, and the cost investment of the host system is very expensive.
With the development of computer technology, especially the gradual maturity of technologies such as mobile internet, cloud computing and the like, a distributed system more suitable for marketization is developed. The distributed system can have the computing power of a plurality of computers, has higher processing speed and can be flexibly deployed in a distributed mode. Compared with a host system, the distributed system has the advantages of fast delivery, resource elasticity, low cost investment and the like. Thus, core banking systems are beginning to migrate gradually from host systems to distributed systems.
However, compared with a large host system which stably operates for many years, the stability of the currently developed distributed system is poor, and a bank needs to provide stable service for a user when performing system transformation. When the business runs in the distributed system, if the distributed system has a sudden problem, the normal business transaction of the bank can be influenced, and if no rollback preparation is made, the business paralysis can be caused.

Fig. 2 schematically illustrates a first flowchart of a system switching method according to an embodiment of the present disclosure.
As shown in fig. 2, the system switching method of this embodiment includes operations S210 to S230, which are performed by the offload service node 104.
In operation S210, a service request of a user is received, and it is verified whether the user belongs to a white list of a new system.

A user A at a mobile phone end of certain bank software needs to perform a transfer service, a transfer request is sent out through the mobile phone end and sent to a shunting service node 104, so that the transfer request of the user is processed by calling the service of a new system branch or an old system branch through the shunting service node 104, before the service is called through the shunting service node 104, the bank card number of the user A is obtained, an Apollo switch is accessed to verify whether the bank card number of the user A belongs to a white list of a new system, and if the bank card number is in the white list, the transfer request is sent to the new system so as to process the transfer request. When the new system processes the transfer request and reports an error, the transfer request is sent to the old system, so that the user A uses the old system to process the transfer, and normal transfer of the user is guaranteed. And if the new system successfully processes the transfer request and the user A subsequently performs other services, re-executing the operations S210-S230. Further, the service request may include other types of requests, such as access requests, subscription requests, query requests, and the like.
When operation S230 is performed, after the new system processes the service request and reports an error, operation S240 is also performed.
In operation S240, after the new system processes the service request error, the user is deleted from the white list.
In one embodiment of the disclosure, when the user A uses the new system to process the transfer request error report, the configuration statement about the white list in the Apollo switch is modified at the moment, the card number of the user A is deleted from the new system white list about the transfer service, and the transfer request of the user A is directly sent to the old system to be processed, so that the normal transfer requirement of the user A is ensured, the service paralysis is avoided, and the stable switching during the system transformation period is ensured.
FIG. 3 schematically illustrates a second flowchart of a system switching method according to an embodiment of the present disclosure.
As shown in fig. 3, after operations S210 to S220 are performed, while the new system normally processes the full-flow service request of the user, a system transformation test of the full-flow service is performed on other users on the white list, so as to ensure that the users on the current white list can all use the new system to normally process the service. When all the users of the white list normally process the service request through the new system, operation S250 is also required to be performed.
In operation S250, when all users of the white list normally process service requests through the new system, non-white list users related to the users in the white list are added to the white list to expand the user range of the white list.
In one embodiment of the disclosure, the current white list users are all users who open an account in Guangzhou city, when the current white list users can all use the new system to process services normally, the configuration of the areas in the user rules of the white list is modified, the attribution area of the card number of the white list user is set to be expanded from Guangzhou city to Guangdong province, and when all the users of the white list after expansion can process service requests normally through the new system, the users in other areas are continuously added to the white list, so that the user range of the white list is gradually expanded until all the users transfer the service systems from the old system to the new system, and complete transfer from the old system to the new system is realized.
In another embodiment of the present disclosure, the current white list users are all users of the mobile phone client, when the current white list users can all use the new system to process services normally, the configuration of the user channels in the user rules of the white list is modified, the web page end users are added to the current white list, and when all the users of the enlarged white list can process service requests normally through the new system, the users of other user channels are continuously added to the white list, so that the user range of the white list is gradually enlarged until all the users' service systems are transferred from the old system to the new system, and the complete transfer from the old system to the new system is realized.
It should be understood that the modification of the user rules of the white list is determined according to the actual needs of the system transformation demander, with the aim of achieving an expansion of the user scope of the white list.
After the new system or the old system processes the service request normally, the service data of the service is generated in the database of the new system or the old system correspondingly. Because during the transformation of the new system and the old system, the two systems are parallel, the new system can not ensure the stability, the old system is ready to be used for processing the service request at any time, the data synchronization of the new system and the old system needs to be ensured, and the situation that a user can not obtain corresponding data in a certain link in the service process is avoided. Thus, operation S260 also needs to be performed.
Fig. 4 schematically illustrates a third flowchart of a system switching method according to an embodiment of the present disclosure.
