The technical scheme of the application is described in detail with specifically embodiment below.These specific implementations below Example can be combined with each other, and may be repeated no more in certain embodiments for same or analogous concept or process.
Fig. 2 is the schematic flow sheet of the upgrade method of the serve end program that the embodiment of the application one provides and database.This Embodiment is referred to server device and currently used database and serve end program is entered using different database manipulations The detailed process of row upgrading, without carrying out Hot Spare to database to save resource, it also avoid incremental data in the prior art Migration caused by towards new and old serve end program database data it is inconsistent the problem of.The embodiment of the present application is mainly for upper State request receiver, request actuator and database upgraded, in the present embodiment, in advance by serve end program it is multiple please Receiver, multiple request actuator division upgrading batches are asked, guarantee has that request receiver is in running order at any time, Remember first upgrading request receiver, request actuator integrate be combined into SA2 (SA2 be in serve end program the second program reality Body, second program entity can include at least one independent program entity), in the second program entity escalation process, when The preceding request receiver for externally providing service, request actuator set are designated as SA1, and (SA1 is the first journey in serve end program Program entity remaining in addition to the second program entity in sequence entity, i.e. serve end program).For convenience of description, it is following to incite somebody to action The request receiver of first upgrading, request actuator set SA2 are referred to as the second program entity, and SA1 is referred to as into the first journey Serve end program in sequence entity, i.e. the present embodiment includes the first program entity and the second program entity.
As shown in figure 1, the present processes can include：
S101：Disable the second program entity, then update second program entity, and update the second program entity it Afterwards, compatible renewal processing is carried out to database used in current first program entity for externally providing service, obtains the One database.
Specifically, server device when upgrading to serve end program, first confirms that the first program entity and second Whether program entity all externally provides service.If the first program entity and the current all external offer clothes of the second program entity Business, then server device disables second program entity, then updates the second program entity of the disabling.By the second of disabling Program entity is updated to after target version, and database used in current the first program entity for externally providing service is carried out Compatible renewal processing, obtains the first database.
It should be noted that the first program entity is current externally to provide service, its currently used database is liter Database before level, after server device carries out compatible renewal processing to the database, compatibility renewal processing causes gained The request actuator of the first database arrived not only the second program entity after compatible above-mentioned renewal, first be also compatible with before upgrading In request actuator in program entity and the second program entity, i.e. the first program entity and the second program entity before renewal Ask the request actuator in the second program entity after actuator and renewal to be based on first database to carry out just Normal business processing, be not in that data access mistake or the first program entity access the database before upgrading and access the Occurs the problem of data are inconsistent during one database.That is, the first program entity now either accesses the number before upgrading According to storehouse, or the first database is accessed, resulting result is not in mistake.It is it should be noted that above-mentioned to database The compatible renewal processing of progress, it will not be modified or delete to current existing data in database, i.e. the first program Entity is directed to same access request, after the result obtained by accessing the database before upgrading and the compatible renewal processing of access Result obtained by database (i.e. the first database) is identical, and the second program entity before renewal accesses for same access request The result obtained by database before upgrading and the second program entity after renewal access the number after upgrading for the access request It is identical according to the result obtained by storehouse (the first database).That is, above-mentioned compatible renewal processing is that can make the number after upgrading According to the certain operations of the second front and rear program entity of compatible first program entity in storehouse, renewal, such as the database before upgrading is increased Add the operation of data row of operation, increase with default value of new database table etc..
S102：The second program entity after control renewal receives access request and caches the access request.
Specifically, after server device obtains the first database, server device can control second after renewal Program entity receives access request, i.e. request receiver in the second program entity after control renewal receives access request, and Received outside access request is cached, the purpose for the arrangement is that in order in following server devices by the first program After entity stops service, serve end program externally remains able to response access request, and (response here is actually that reception is outside Access request but delay to handle, but for outside access equipment, still worked on equivalent to serve end program), it is ensured that Serve end program is interrupted in escalation process and interacted with outside access equipment.
S103：Control first program entity to stop receiving access request and update first program entity, and, Non-compatible renewal processing is carried out to first database, obtains the second database.
Specifically, after above-mentioned S102 is performed, server device controls current first program entity to stop receiving access Request, access request is externally received by the second program entity after above-mentioned renewal, as stated above, the purpose for the arrangement is that being After the first program entity stops receiving access request, for external equipment, the second program entity after renewal still receives The access request of external equipment, therefore so for external equipment, serve end program is not stopped.Now, service After access task of the end equipment on the first program entity is confirmed all returns to implementing result, the first program entity can be updated Or target version (target version is identical with the version of the second program entity after above-mentioned renewal) is upgraded to, after obtaining renewal The first program entity.
On the other hand, because the second program entity after above-mentioned renewal is the access request outside reception, therefore, it is not It is related to the operation to the first database, so, server device can carry out non-compatible renewal processing to first database, obtain To the second database.The non-compatible renewal processing includes the place that the current existing data of first database are modified or deleted Reason, these handle the first program entity and the second program entity before incompatible upgrading, that is, the second program entity pin before updating Access an access request database before upgrading and the second program entity after renewal and access the second number for the access request Inconsistent situation occurs in the result obtained according to place, and the first program entity before renewal accesses upgrading for an access request The first program entity after preceding database and renewal can go out for the result obtained by the access request the second database of access Existing inconsistent situation.
In the embodiment of the present application, why compatibility formerly is carried out more to database used in the first program entity before renewal New processing, it is because the first program entity is still externally provided using the database before upgrading after the second program entity stops service Service, therefore, if formerly carrying out non-compatible renewal processing to database used in the first program entity before renewal, it may appear that First program entity access upgrade before database and access through non-compatible renewal processing after database when, corrupt data or The problem of person's data are inconsistent, still, if formerly carrying out compatibility more to database used in the first program entity before renewal The problem would not occur in new processing, and specific explanations may refer to above-mentioned S101 description.It should be noted that in the present embodiment The sequential relationship that non-compatible renewal processing is carried out to the first program entity of renewal and to the first database does not limit.
Therefore in the present embodiment, after the two the second program entities of server device renewal disabling, formerly to it is current externally Database used in first program entity of service is provided and carries out compatible renewal processing, obtains the first database, it is ensured that first Data are consistent when program entity accesses upgrading front and rear database；Then server device is controlling the first program entity to stop connecing When receiving access request, the second program entity after control renewal receives and cache access request, with the second program in the updated When the first database is not used in entity, non-compatible renewal processing is carried out to the first database, obtains the second data, so that rising Database before level obtains complete updating operation, and the front and rear serve end program of upgrading will not be brought to access the number before upgrading There is the problem of access errors according to storehouse and when accessing the database after upgrading, it is hot standby without being carried out to the database before upgrading, Resource is greatly saved, also, the incremental data migration being also not present between the front and rear database of upgrading, avoid the occurrence of upgrading Front and rear serve end program accesses the problem of data are inconsistent.
After the second database is obtained, after the second program entity and renewal after the control renewal of server device can The first program entity externally provide business service using the second database.
The serve end program and the upgrade method of database that the embodiment of the present application provides, by current disabled in renewal After second program entity, database used in current the first program entity for externally providing service is carried out at compatible renewal Reason obtains the first database, and then in server device after controlling the first program entity to stop receiving access request, control is more The second program entity after new receives and cache access request, and updates above-mentioned first program entity and the first database is entered The non-compatible renewal processing of row, obtains the second database.In the embodiment of the present application, the first data obtained by being handled by compatible renewal Storehouse so that current the first program entity for externally providing service is directed to same access request, is accessing the database before upgrading The result obtained by database (i.e. the first database) after the renewal processing compatible with access of resulting result is identical, it is ensured that when Access data are consistent when the first program entity that offer services preceding externally accesses upgrading front and rear database, avoid access result from going out It is wrong；Meanwhile by server device when the first program entity stops receiving access request, the second program after control renewal is real Body receives and cache access request, and for external equipment, server-side devices are currently still receiving access request, The business that serve end program externally provides not interrupt, ensure that external equipment by serve end program access database when Continuity；In addition, server device by control the above-mentioned database to before upgrading carry out compatible renewal processing and it is non-compatible more The order newly handled, so that the database before upgrading obtains complete updating operation, and it will not bring before and after upgrading Serve end program accesses the database before upgrading and the problem of access errors occurs when accessing the database after upgrading, without right Database progress before upgrading is hot standby, greatly saves hot standby resource, also, is also not present between the front and rear database of upgrading Incremental data migration, avoid the occurrence of upgrading before and after serve end program access data it is inconsistent the problem of.
