Embodiment Construction

[0038] The core idea of ​​the present invention is to apply for a new memory area, and generate an upgraded embedded database in the new memory area; switch the address of the current memory area of ​​the embedded database recorded by the kernel base address to the new memory area The address of the zone.

[0039] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0040] The embedded database itself is not a complete database system, it needs to be bound with the specific upper application system to realize various operations and access to the embedded database. A typical implementation of an embedded database is to apply for a memory area and manage the memory area. In this embodiment, the specific management method to the embedded database is to define a global variable of the upper-level application system: kernel base address, which is used to record the starting address of the block memory, so that the o...

Abstract

The on-line upgrade control method for embedded database comprises: applying new memory area to generate upgraded database, and switching the current area address recorded in kernel base site into the new one. This invention can keep service continuality by on-line upgrade.

Description

technical field [0001] The invention relates to an embedded database, in particular to an online upgrade control method and device for an embedded database. Background technique [0002] Embedded database, as a highly efficient and compact database system that is closely integrated with specific applications, is widely used in the field of communication. Because the embedded database system is highly pertinent and tightly bound to specific applications, it has the characteristics of "customization". Therefore, once the upper-level application system it serves changes, the corresponding part of the embedded database system that supports the upper-level application system It also needs to change accordingly. [0003] As a typical embedded database system implementation, its principle is to apply for a block of memory and plan it in a specific way to manage the access of data required by the upper application system. It can be seen that the data requirements of the upper appl...
