Problems solved by technology

[0011] (1) Due to the need for multiple write and read operations during the synchronization process, the data synchronization speed is relatively slow;
[0012] (2) Any alarm / recovery messages during the data synchronization process will be discarded, and due to the long synchronization time, the probability of this situation is also high

Embodiment Construction

[0031] According to Figure 1 ~ Figure 7 Given an example of the present invention,

[0032] See figure 1 As shown, it represents the image of external memory data in memory,

[0033] Memory data blocks A and B are mutually active and standby areas at different times when the system is running: when data block A is the active, data block B is the standby; vice versa.

[0034] See figure 2 As shown, it represents the storage method of a single data table in the memory, which is correct figure 1 The refinement.

[0035] For each relational table, there is a table description information block, of which there are two pointers, one is the primary area pointer, and the other is the standby area pointer, which respectively point to the two areas of the main and standby areas, indicating that the memory block referred to is in the system In the active or standby state. When the main and standby memory needs to be switched, it can be completed by simply swapping the addresses pointed to...

Abstract

A data main and standby internal memory process method relates to double internal memories process of data management, which is to divide the carried data internal memory into main store and standby store areas with related main area and standby area pointers to be switched to realize their transfer. In operation, the standby data before corrected must be ensured in conformity with main area data, then synchronize the "new" data to the standby area, after that, to switch main and standby pointers, the synchronous data is valid, if synchronization fails, then sending out order of fail.

Description

Technical field [0001] The invention relates to a method for managing data in a memory, which has strong practical value in the field of communication or computer. Background technique [0002] During the operation of the GSM (Mobile Phone Global Communications) system, it is necessary to adjust the data on the BSC (Base Station Controller) through the OMC (Operation and Maintenance Center), but it should not affect the normal operation of existing services. And it is required to quickly roll back to the state before the modification when there is an error in the data synchronization. BSC is a real-time control system. Its MP (Main Processor) adopts hot backup technology to ensure the consistency of data on MP, which is of great significance for improving the stability of the entire system. [0003] For this reason, in the existing system, the commonly adopted method is: [0004] When the system starts, the data is loaded into the memory. There is a corresponding working director...
