Particularly, in the above-mentioned steps 1208, standby database place server 704 upgrades the detailed process of standby database based on the update mode of determining, the concrete implementation basically identical with above-mentioned steps 910 repeats no more herein.
In the practical application scene, renewal for same business datum may be concurrent, be that the service server 304 shown in Fig. 3 may be used for the more information of new database at many of the business datum generations of same Data Identification, and may be because network delay, the difference of database place data in server disposal ability etc., should be used for the more information of new database at many that the business datum of same Data Identification produces, and not necessarily can arrive database place server (comprise main with database place server 302 or/and standby database place server 303) according to the order that service server 304 produces.For example at the information priority arrival database place server of the nearest information that produces of the business datum of same Data Identification than more Zao generation, in this case, may cause the business datum backup inconsistent, even the nearest information that produces of generation is by the problem of the information of generation more early covering.At this problem, in the application's preferred embodiment, can also comprise the time marking that is used to identify this business datum rise time in the business datum that message-oriented middleware server 301 receives; If determine database (promptly main with database or standby database, among this embodiment, the follow-up situation that database occurs similarly, all refer to main with database or standby database) update mode for according to data corresponding in the business datum replacement data storehouse with this business datum, then before new database more, also comprise:
According to that preserve in the time marking of the business datum that receives and the database and the time markings corresponding data of this business datum, determine whether the rise time of this business datum is later than the rise time of data corresponding with this business datum in the database, if then carry out database update; As not, do not carry out renewal.
In the practical application, above-mentionedly be used to identify the time marking of this business datum rise time and can realize by the mode of version number, promptly the business datum that successively each time is generated according to the business datum rise time adopts the incremental manner numbering, after utilizing this service data updating database, in database table, increase a field that is used to identify version number.In the time need carrying out database update next time, whether the business datum of at first judging this less important renewal exists corresponding data (data that promptly whether have corresponding same Data Identification) in database, if exist, whether the version number of the business datum that has existed in the judgment data storehouse is less than newly arrived business datum, if, carry out and upgrade operation, otherwise refuse this renewal.
Be to be understood that, above-mentioned mode by version number realizes that the mode of time marking only is the application's preferred embodiment, according to the embodiment of the present application, the existing way of this time marking can also be set according to actual needs flexibly, for example, can be directly with rise time of business datum time marking as this business datum, before database is carried out renewal at the business datum of same Data Identification, at first whether the rise time of the data in the judgment data storehouse is early than rise time of newly arrived business datum, if, carry out and upgrade operation, otherwise refuse this renewal.
Further, in the application's preferred embodiment, consider that the data of storing in the database adopt the form storage of Microsoft Excel morely, when new database more, at first need to duplicate the corresponding business data, for example, when standby database place server upgrades standby database at needs, at first need from leading with obtaining the corresponding business data the database, the acquisition process of this business datum also is the reproduction process of business datum.Concrete copy mode can adopt row to duplicate and the incremental replication dual mode, and wherein, row duplicates and promptly all duplicates full line at every turn; Incremental replication is only to duplicate the data that change at every turn.In order to understand these two kinds of copy modes that the embodiment of the present application provides better, be described as follows below in conjunction with system shown in Figure 3 and instantiation:
Tables of data about person (personal information), comprise name (name), age (age), sex (sex), four fields of version (version number), the mode that row duplicates is, each name, the age of each version correspondence, content of three fields of sex of all duplicating, and the mode of incremental replication is, only duplicates the field contents of change in three fields of name, age, sex of each version correspondence, for example:
Under the circumstance of initialization, the content in the tables of data is:
| Name | age | sex | version |
| Zhang Si | 20 | The man | 1 |
At this moment, standby database place server 303 and main content synchronization of preserving with database in the server 302 of database place.
Suppose to have carried out twice renewal with this tables of data in the database at main, as follows respectively:
After upgrading for the first time, theing contents are as follows in the tables of data:
| Name | age | sex | version |
| Zhang San | 22 | The man | 2 |
After upgrading for the second time, theing contents are as follows in the tables of data:
| Name | age | sex | version |
| Zhang San | 20 | The man | 3 |
According to above renewal, the reproduction process of standby database place server 303 is as follows:
If employing incremental replication, can produce two replication task at this twice Data Update so, a replication task is the content of the change of correspondence when duplicating version=2, promptly duplicate name=Zhang San, age=22, the another one replication task is the content of the change of correspondence when duplicating version=3, promptly duplicates age=20, version=3.Wherein, these two replication task can not guarantee strict execution sequence, therefore, the contingent situation of this copy mode is, the content of the change of version=3 correspondence, be performed earlier as age=20, this time the version=2 correspondence the content of change, as name=Zhang San, age=22 just has not been performed, reason is, the version of these data has become 3 in the database, has no longer received the renewal of lowest version, therefore, the content after standby database place server 303 final updated may be with main different with the content in the database place server 302.
If adopt row to duplicate, also can produce two replication task at this twice Data Update so, promptly respectively at twice renewal, duplicate all fields (comprising field that change takes place and the field that change does not take place), promptly a replication task is duplicated " Name=Zhang San; age=22; sex=man; verison=2 ", another replication task is duplicated " Name=Zhang San; age=20; sex=man; verison=3 ", at this moment, duplication sequence can not have influence on final result, because if version=3 is performed earlier, be up-to-date data this time so, therefore, adopt the capable content that can guarantee better in the standby database place server 303 of duplicating to use the content in the database place server 302 consistent with main.
