In an alternative embodiment, after the determining system stores M serial numbers in the first database table and the second database table, determining a first loading threshold corresponding to the first database table, where the first loading threshold is used to characterize a product of a total number of all serial numbers stored in the first database table and a preset percentage, and then loading the second database table if the serial number corresponding to the first loading threshold is used; in addition, a second loading threshold corresponding to the second database table is determined, wherein the second loading threshold is used for representing the product of the total number of all serial numbers stored in the second database table and a preset percentage, and then the first database table is loaded under the condition that the serial number corresponding to the second loading threshold is used.

Optionally, the purpose of dividing the serial number to be used into two number segments for caching is achieved by setting the double database table in the target serial number, and after the serial number stored in the database currently being used is consumed by a preset percentage, the determining system loads the serial number stored in the other database table in advance, so that the problem that the serial number stored in the first database is consumed rapidly due to burst traffic, but the serial number stored in the second database table cannot be loaded timely is avoided, and the determining system can control the time for loading the serial number in advance by changing the sizes of the first loading threshold and the second loading threshold, so that the reliability of the determining system is improved.

In an alternative embodiment, the determining system first determines the margin corresponding to the first sequence number as a target margin, then detects whether the target margin is equal to a preset threshold, where the preset threshold is a first preset threshold or a second preset threshold, then determines the second sequence number corresponding to the first sequence number as a target sequence number if the target margin is equal to the preset threshold, where the second sequence number is a sum of the first sequence number and a preset increment, and further determines the third sequence number corresponding to the first sequence number as a target sequence number if the target margin is not equal to the preset threshold, where the third sequence number is less than the sum of the first sequence number and the preset increment, and where the third sequence number is a multiple of the preset threshold.
