In the embedded database of present embodiment, can include only a database table, in this case, do not need the start address offset information of system management segment record database table, and directly embedded database is carried out operational access by the kernel plot.
The online upgrading control method of embedded database may further comprise the steps as shown in Figure 3 in the present embodiment:
Step S101, the mode by hot patch offers the upper layer application system with the data processing method of upper layer application system redaction and the upgrade information that supports the embedded database of this redaction data processing method;
Adopt the mode of hot patch, can be in system's operational process, the data processing method of upper layer application system redaction and the upgrade information that supports the embedded database of this redaction data processing method are offered the upper layer application system.And, make the upper layer application system can distinguish the data processing method of legacy version and the data processing method of redaction, can adopt the data processing method of legacy version or the data processing method deal with data of redaction.Equally, the information of the embedded database that upgrading is preceding and the information of the embedded database after the upgrading also can be known in the upper layer application system.
In the present embodiment, by recompilating and pass through the mode replacement function DbInitFunc of hot patch, embody the data processing method of upper layer application system redaction and the upgrade information that supports the embedded database of this redaction data processing method among the function DbInitFunc after replacement, thereby the data processing method of upper layer application system redaction and the upgrade information that supports the embedded database of this redaction data processing method are offered the upper layer application system.The upgrade information of embedded database comprises database structure, system management section initial value and each database table initial value etc. of the embedded database after the upgrading of upper layer application system expectation.The structure of this upgrading back embedded database should comprise system management section and database table, and wherein system management section is set at the reference position of this upgrading back embedded database.
Step S102 is according to new region of memory of structure application of upgrading back embedded database in the upgrade information of this embedded database;
Step S103 is according to the system management section of the structures shape of upgrading back embedded database in this new region of memory of upgrade information initialization of this embedded database, with the start address offset information writing system management section of each database table;
Step S104, according to predefined configuration in this upgrade information, each database table of the structures shape of upgrading back embedded database in this new region of memory of initialization;
In the present embodiment, find each database table according to the start address of this new region of memory and the start address offset information of each database table.
Step S105 is in the embedded database of the data sync in the embedded database before the upgrading after the upgrading, to guarantee the continuity of service;
Owing to be mode replacement function DbInitFunc in the present embodiment by hot patch, the information of the embedded database before the upgrading and the information of the embedded database after the upgrading can be known in the upper layer application system, therefore, in this step, contrast the information of the embedded database before this upgrading and the information of the embedded database after the upgrading, can know the embedded database variation structurally before embedded database after the upgrading is with respect to upgrading.
In specific implementation, database structure between the embedded database after embedded database before the upgrading and the upgrading often only is the part difference, to the part that the data library structure is not done to change, the relevant position of the data in the embedded database before the upgrading being moved the embedded database after upgrading; To the part of data library structure change, the data in the preceding embedded database of then will upgrade are fitted in the embedded database after the upgrading.But in specific implementation, also there is the diverse situation of both database structures, in this case, the data in the embedded database before the upgrading is fitted in the embedded database after the upgrading.
In an example of the present invention, there is the form of a management VIP user profile in the embedded database before the upgrading, record VIP user's name, identification card number.In the embedded database after upgrading, the form of this management VIP user profile need increase by one ' networking time ', and the networking time that is used to write down VIP user, then change has taken place the structure of this form.' networking time ' information for increasing newly can keep its initial value, treats follow-uply to be adjusted again; And for existing user profile in the embedded database before the upgrading, promptly VIP user's name, identification card number then need to move in the embedded database after the upgrading.
Step S106 is the start address of this new region of memory with the address switchover of the current region of memory of this embedded database of kernel plot record, makes this new region of memory of start address point to to(for) the operational access of this embedded database;
When switching the kernel plot, end all operations visit of current this embedded database.In the present embodiment, above-mentioned switching kernel plot is to realize by a function.In the time will carrying out the switching of kernel plot, call this function, in case enter this function, the system call not permission task of locking is switched, end all operations visit of current this embedded database, give this kernel plot with the start address assignment of new embedded database place region of memory then, the system call release, thus finish the switching of kernel plot.
Step S107, after the success of switching kernel plot, the upper layer application system uses the data processing method of redaction, and discharges the region of memory of the preceding embedded database of upgrading.
In the present embodiment, the upper layer application system is after knowing the data processing method of redaction according to the function DbInitFunc after replacing, still use the data processing method deal with data of legacy version, after switching the success of kernel plot, for providing the embedded database of data, the upper layer application system become the embedded database after the upgrading, accordingly, the upper layer application system brings into use the data processing method of redaction.
In the specific implementation of this step, need a global mark, whether sign kernel plot has switched is finished.After the switching of kernel plot is finished, this global mark is set, the upper layer application system judges then whether this global mark is set up the data processing method that determines whether using redaction.
In above-mentioned example, in the data processing method of the redaction of upper layer application system, should comprise the data processing that has increased ' networking time ' for the form of this management VIP user profile newly, but before switching the success of kernel plot, the actual data that read of upper layer application system are still provided by the embedded database before the upgrading, the record that does not comprise ' networking time ', therefore, before switching the success of kernel plot, use the data processing method of legacy version, after switching the success of kernel plot, use the data processing method of redaction.
In above-mentioned flow process, from step S102 to S105, in concrete enforcement, may occur unusually, when any one link among the step S102 to S105 occurs stopping subsequent treatment when unusual, discharge this new region of memory.
