Provide the detailed description of the technical scheme that the embodiment of the invention provides below.
Irredundant distribution principle: data are divided according to implementor's (being application program), in every table, increase implementor's field, a corresponding application person (the being application program) name of each implementor, this name may refer to the application entity of a reality, it also may be the abstract entity (when same object is used in same the table in a plurality of application) of a plurality of application entities, application program need be to the name of database broker registration oneself initialized the time, the agency sends synchronization request by this name to database server, server travels through all records in all tables, all records that will comprise the apply names of request are synchronized to database broker, obtain data with EOS offspring reason by call back function notification application (being application component), it is the interface that application component calls this system, name according to the implementor in the record in interface is the application component return recording, simultaneously server need be with agency's log-on message (comprising the source IP and the port numbers of the application program of acting on behalf of the place, the name of application program, relevant call back function) registers, need be synchronized to which agency so that in configuration change, determine change.Wherein, a plurality of records of same apply names in can corresponding a plurality of tables.
By this principle, the data that each agency goes up initial distribution all are the data of application program oneself, because during application initialization to agency of trademark registration, the agency is to the record of this application program of server requests, and server is synchronous with the agency by the name of implementor's name in relatively writing down and application program, after the agency is synchronized to record, the call back function of invokes application, application program is obtained data in call back function, after call back function returned, application program just got access to the initialization data of oneself.Application program can will arrive all data that oneself need in that initial phase is disposable like this, does not have redundant data to exist, and access of database is all finished getting final product later in this locality; When data change, by the log-on message that writes down on the server, changed content is synchronized on the corresponding peripheral node, being about to changed content is synchronized on the agency, the call back function of agency and then invokes application, application program is obtained data by the interface that provides of agency is provided in call back function, interface only returns the data of application program oneself according to the log-on message of application program.
Wherein, peripheral node can be a veneer, also can be a process.
Distributed synchronization process under this principle as shown in Figure 3, that the representative of each english abbreviation is the name of an application component (being application program), for example NTF, SMF, PLM and CLM among this Fig. 3.The object of the content representation application component that data are pointed.
Memory organization:
Because the object in the reality all has set membership, be to have incidence relation between each object, every record organizes no longer according to the sequential organization mode that writes down in the his-and-hers watches, but become object tree according to the set membership tissue of object, the table of having avoided like this having incidence relation carries out association by redundant field, only need in table, increase the association that the parent object field can be represented, Zu Zhi benefit is the parent object of access object very easily like this, also can visit all subobjects of an object very easily, thereby carry out for object set that operation is very easy with set membership.
The memory organization of object, is organized according to set membership when object is organized in internal memory automatically referring to Fig. 4, set membership can directly find from tree, each circle is represented an object, and each object comprises a plurality of object information, and each object information comprises a plurality of attribute informations.
For configuration change, also with the configuration change object tissue be and the similar tree of tree shown in Figure 4, during the application access object, begin layering traversal object (being called for short the layering traversal) from tree root, also can travel through each subtree (being called for short degree of depth traversal) according to the degree of depth of tree, particularly: the configuration change object is organized as the change tree according to the set membership of object, the agency provides next (next) interface to be used to travel through this tree, provide one to go into to join to judge that the layering traversal still is a degree of depth traversal in this interface, configuration change at first will change object synchronization to relevant agency by server, the agency will change group of objects and be made into the configuration change tree, the call back function of proxy call application program obtains data, and call back function calls the next interface and obtains one's own change object.
The layering traversal: root is the 0th layer, the object that begins to belong to this application program from root with every layer returns by the next interface, this layer of traversal finishes, travel through the object of one deck down then, whenever traverse an object, return by the next interface, do not belong to this application program, directly travel through next object.
Degree of depth traversal: begin traversal from root,, all travel through up to all parent objects and their subobject and to finish, whenever traverse an object, return, do not belong to this application program, directly travel through next object by the next interface up to leaf node.
Obtain configuration change by above-mentioned different access method and concentrate relevant object, the attribute of each object points to array of pointers, attribute of each pointed, Zu Zhi benefit is that the attribute of object can independently upgrade like this, the renewal of each attribute is not disturbed mutually.When being the attribute of upgating object, the attribute of object is organized in the structure array, and each structure is represented an attribute updating information, comprises the new value of attribute-name, attribute type, attribute etc., can upgrade one or more property value, constant attribute is unaffected.
Configuration change is synchronous: when webmaster is configured change, need the configuration change collection be sent to server end by business process, server end with the configuration change set cache in extra buffer, and according to agency log-on message configuration change is synchronized on the relevant agency, promptly be synchronized in the application corresponding process according to the implementor in the record, the change object that the agency will be synchronized to is organized into interim configuration change tree according to the set membership of object, do not directly apply to local data base, treat with behind the EOS, the agency carries out verification by call back function notice application process to data and (specifically adopts the data check rule of application program oneself definition, such as field scope verification etc.), if data are after all verification is passed through, the agency that server end is relevant with all is applied to configuration change collection or subclass in the local data base, if data check failure, abandon this business process on the server, each agency goes up and discharges interim configuration change tree, the benefit of doing like this is, need when revising data, not back up, save the EMS memory occupation of database so greatly entire database.
Wherein, described business process, it is an atom process of data configuration, the webmaster that webmaster is issued the configuration change data object on the network element is adaptive, the adaptive parsing configuration change of network element data object, and with announcement server, configuration data is organized in the server analysis, and be synchronized on each related proxy, server is the most whole process of synchronized result notice webmaster.
Wherein, described log-on message according to the agency is synchronized to configuration change on the relevant agency, comprising:
Step 1: server is provided with agency's log-on message (comprising application name), and is provided with implementor's name (being the application name title) in the object (i.e. record).
Step 2: on the server configuration object is organized chaining according to implementor's title.
Step 3: carry out synchronously at each implementor on the server, at each implementor, the group of objects bag that this implementor is correlated with sends on the agency, up to all same EOS of all implementors.
The operation change is synchronous: when application process is moved change, api interface on the application call agency is new database more directly, because the operation change may need to notify webmaster, so the content of operation change need be synchronized to server end, the agency notifies the field of change on the server according to the form of determining, specifically comprise: the attribute that upgrades according to structure array organization, is sent out message to server, resolve the memory database of information updating server itself on the server.Upgrade local database according to the operation changed content on the server, each agency knows if desired that mutually to the renewal of service data, intermediary notifies by notification service, the purpose that issue and the subscription by this intermediary reaches the renewal of notice service data.
In configuration change changes synchronously with operation synchronously, in order not make configuration change and operation change conflict mutually, the both carries out synchronously at the change field of record, avoid whole piece to write down when synchronous problem owing to both sequential and caused the problem that covers mutually, the most important thing is synchronous form according to field sync, transmit leg must and be resolved the change data according to identical format organization with the take over party.
Agency and server are arranged the field sync form in advance, synchronous form as shown in Figure 5, wherein object name be can an object of unique identification field, the object name is overall unique in entire database.Source address, i.e. Dai Li IP address and port numbers.Shown in Figure 5 is organized formats to object information, and transmit leg is according to this form group bag, and the take over party is according to this format analysis bag, and the size of every bag is no more than 64k, and all is complete record in the bag.
