Embodiment
The present invention is applicable to the database synchronization processing of comprehensive access telecommunication apparatus.Partly push away half (halfpush according to method for synchronous employing between plate of the present invention, halfpull) mechanism realizes, the content that master control borad initiatively pushes away not is the real data body, and be the sequence number of a record current data update mode, receiving terminal carries out sequence number relatively, when discovery need be carried out Data Update, adopt pull mechanism to move real data to this locality.
For making the purpose, technical solutions and advantages of the present invention clearer,, the present invention is described in further detail below in conjunction with drawings and the specific embodiments.
According to embodiments of the invention, method for synchronous between a kind of plate of configuration data has been proposed.
Fig. 1 is the flow chart according to method for synchronous between the plate of the configuration data of the embodiment of the invention, and as shown in Figure 1, this method comprises:
Step S102 is divided into a plurality of sync sections with the business to be configured data, and wherein, the sync section sequence number corresponding with sync section is along with the renewal of the business datum in the sync section is upgraded;
Step S104, master control borad is to ply-yarn drill timed sending sync section sequence number;
Step S106, ply-yarn drill will be compared with the sync section sequence number of local storage from the sync section sequence number of master control borad;
Step S108, ply-yarn drill is the business datum of the sync section of inconsistent sync section sequence number correspondence to master control borad application comparison result, to upgrade local business datum.
Describe the details of above-mentioned processing in detail below in conjunction with Fig. 2.At first, at master control borad the business to be configured data are divided the processing of sync section.Sync section is " organization mechanism " of carrying out the tables of data configuration synchronization, because the length restriction of message between different boards, need divide sync section to the business to be configured data, sync section is the open ended business datum of message between a batten, and, the some nodes of storage in each sync section, a record in each node representative data table, the node parameter information in this sync section is: flag bit, index data record.
Particularly, carrying out sync section according to following formula divides:
The open ended business datum clauses and subclauses of sync section number=maximum data table clause number/a piece of news;
The open ended data entry number of message between the node number in the sync section=batten.
And, sync section sequence number corresponding of storage in each sync section with this sync section.
(increase, delete, revise) when the business datum in the sync section is updated, this sync section sequence number also upgrades.Be that example describes with SQL (Structured Query Language is called for short SQL) database below.Three kinds of write operation primitive for the SQL operation carry out following processing:
(1) increases operation.Distribute an idle node (simply traversal or other distribution mechanisms all can) according to the data record that increases, the storage index data record, the flag bit of node is made as " effectively ", incidence relation between record node subscript and the index data record, as passing through Adelson-Velskii-Landis tree (binary search tree) or C++ STL (Standard Template Library, abbreviation STL) associated container MAP etc. carries out association, also can adopt other correlating methods, does not give unnecessary details herein.Simultaneously, the residing sync section sequence number of node is increased progressively.
(2) retouching operation.When data record is modified, find node (above-mentioned associated container method is searched),, then the residing sync section sequence number of node is increased progressively if the node flag bit is " effectively " according to index data record.
(3) deletion action.When data record is deleted, find node (above-mentioned associated container method is searched), if the node flag bit is " effectively ", then this node canned data is removed, and flag bit is made as engineering noise according to index data record.Simultaneously, the residing sync section sequence number of node is increased progressively.
Through after the above-mentioned processing, can adopt " partly pushing away half " mechanism to carry out data synchronization operation between plate.As shown in Figure 2, the preferred process scheme according to method of data synchronization between the plate of the embodiment of the invention comprises following processing:
Step S202, master control borad is to the sync section sequence number of one or more all sync sections of ply-yarn drill fixed time broadcast.Whether the purpose of broadcast synchronization section sequence number is to allow the data of the relatively more local storage of data receiver (ply-yarn drill) be consistent with the data of data source, if renewal has taken place inconsistent expression data.Because the sequence number of each sync section is only with integer of record, and sync section can cover the record of many reality, so just needn't all actual database contents of periodic broadcasting, therefore, farthest reduced the message overhead of periodic broadcasting.
Step S204, ply-yarn drill receives the sync section sequence number from master control borad, this sync section sequence number and the sync section sequence number of local storage are compared, if certain sync section sequence number is inconsistent, then send out the sync section data record of this sync section sequence number correspondence of message application to master control borad, for example: message content is the sync section sequence number.
Step S206, master control borad receives synchronous data requests, the pairing business datum of node on the ply-yarn drill transmission sync section corresponding with this sync section sequence number.
Concrete mode is: external module articulates the callback interface (input index data record number get final product) of a reads data log, can obtain the data record content of reality by the index of sync section node record.The ordering of data is pressed the order arrangement of sync section node correspondence in the message body of transmission message, and data content is as follows: flag bit; Index data record; The data record content.
Ply-yarn drill carries out Data Update after receiving sync section data from master control borad.If the sync section node of correspondence position does not exist in the data that receive, the sync section node of local storage exists, and then deletes local node, and calls the delete interface (input index data record) that database table provides, delete database record.
If the node of local storage exists, then need further comparison: if the data directory unanimity, call recording setting callback interface (the input data record content that database table provides, database index), data content is provided with to database, the realization of callback interface can judge whether this record exists, and data content do not have and change, and does not change and does not directly return.If data directory is inconsistent, then call the deletion callback interface of database table earlier, delete this record, call the recording setting callback interface again, this new record is set.
Through after the above-mentioned processing, if the pairing data-base recording of this sync section all upgrades success, then revise the sync section of the local storage of ply-yarn drill the node content, to upgrade the sync section sequence number be sync section sequence number in the main control board data message, otherwise do not revise the sync section information (just not revising as long as there is a business datum not upgrade success) of local storage.
