step 101, when the monitored switching mark is not switched, the newly received transaction is sent to the old system of the corresponding area according to the routing table;
102, when the monitored switching mark is in switching, acquiring all in-transit transactions, which are the transactions already sent to the old system and not fed back after overtime, and adding the in-transit transactions to a cache pool; adding the newly received transaction to a cache pool;
step 103, when the monitored switching mark is after switching, transmitting the transaction in the cache pool to a new system in the corresponding area according to the routing table until the transaction in the cache pool is transmitted, and releasing the cache pool; transmitting the newly received transaction to a new system of the corresponding area according to the routing table;
and 104, when the monitored switching mark is that the switching is completed, transmitting the newly received transaction to a new system in the corresponding area according to the routing table.
In the embodiment of the invention, the transaction continuity of the new and old systems is ensured by performing caching or direct sending through triggering of a plurality of switching states.
In practice, when the new system is ready and the old system is ready for switching, the old system needs to be kept synchronous to the new system in real time. And stopping external service by the old system when the switching state is that the switching is completed.
In step 101, when the monitored switch flag is not switched, the newly received transaction is sent to the old system in the corresponding area according to the routing table, and the old system is not a distributed system generally, the second level route does not need to be read.
In step 102, when the monitored switch mark is in switch, all in-transit transactions are acquired and added to a cache pool, wherein the in-transit transactions are transactions which are already sent to an old system and are not fed back after overtime; the newly received transaction is added to the cache pool, wherein the time-out period is based on the business system processing speed, such as 99.9% of the time that the transaction can be completed.
In one embodiment, the routing table includes a primary route and a secondary route, where the primary route is routed according to an area (such as an organization number) to which the account number of the transaction belongs, and the secondary route is routed according to a system to which the account number of the transaction belongs.
In one embodiment, the method for sending the transaction in the cache pool to the new system of the corresponding area according to the routing table comprises the following steps: when the new system is one, the transaction in the cache pool is sent to the new system of the corresponding area according to the first-level route in the routing table; when the number of the new systems is multiple, the transaction in the cache pool is sent to the new system in the corresponding area according to the second-level route in the routing table;

and sending the transactions in the cache pool to a new system in the corresponding area according to the routing table according to the sequence of the transactions in the cache pool. Such as deposit, if a subsequent withdrawal transaction is sent to the new system in advance, an error in reporting of insufficient balance may result. In addition, the peak pressure can be reduced by sequentially transmitting.
In one embodiment, the handoff marker is updated from non-handoff to handoff when the old system switches to the new system during the low-valley phase of the transaction. In the off-peak stage of the transaction, the pressure of the old system synchronizing with the new system becomes lower, the amount of synchronized data becomes smaller, and thus the in-transit transaction of the old system becomes smaller.
The transaction routing device for switching between the new system and the old system, which corresponds to the method provided by the embodiment of the invention, can be a part of the new system or an independent device.
