Embodiment
It is below in conjunction with the accompanying drawings and specific real to enable the above-mentioned purpose of the application, feature and advantage more obvious understandable
Mode is applied to be described in further detail the application.
When user uses computer, software can be usually updated, and legacy version is substituted using redaction.Application in network
Platform is also that the application in platform often increases New function, improves old function in this way, in order to provide the user with more preferable service
Deng will now produce redaction application.Redaction application needs are debugged to after without mistake, the formal on-line running of ability, and
Redaction application needs the trial operation in the network platform, could find mistake, modification mistake, be finally completed debugging.For not shadow
The execution of business in platform is rung, can run that redaction is applied and legacy version application, i.e. business i.e. can be in redactions simultaneously
Perform in, can also be performed in legacy version application.
, it is necessary to be migrated online to data when more redaction is applied in the network platform.According to method be advance
By the Data Migration in old database into new database, then when new, legacy version application is operated together, redaction application is still
New database is so accessed, still, when legacy version application accesses old database, to forbid the write operation to old database, i.e. old edition
This application is only capable of reading data, it is impossible to writes data, is then then turned on new database to the increment synchronization of old database.So, in industry
The change of data is just only occurred in new database during business performs, and can be ensured in new, old database by increment synchronization
Data it is consistent.
But this method the problem of existing is, write operation to old database is applied due to prohibiting legacy version, will
The business in legacy version is applied is caused to perform failure.
Therefore, the application proposes to be answered stage by stage using the online data moving method of renewal in a kind of network platform
Renewal, new, legacy version application can conduct interviews to database, the problem of being not in service fail.
Reference picture 1, give in a kind of network platform described in the embodiment of the present application using the online data migration side of renewal
Method flow chart.
Reference picture 2, give the schematic diagram applied in three phases described in the embodiment of the present application to database access.
Step 101, the first stage of renewal runs redaction and applied with legacy version application simultaneously, redaction application in operation
Applied with legacy version and old database is conducted interviews；
Using when being updated in system, while new, legacy version application and new, old database be present, therefore three can be divided
The renewal that the individual stage is applied.
The first stage of renewal as shown in a in Fig. 2, in the first stage of renewal, had both run redaction application, again in system
Run legacy version application.In operation, legacy version application accesses old database, and redaction application is same to access old database, wherein,
The old database is the database that legacy version is applied in the network platform.
In above-mentioned running, redaction can be detected using whether there is problem, if problem be present can change, then
Rerun, until terminating the first stage of renewal.
Step 102, terminate the first stage of renewal, the data full dose in old database is synchronized in new database, and
Into the second stage of renewal, at the same run redaction apply and legacy version application, in operation redaction apply to new database
Conduct interviews, legacy version is applied and old database is conducted interviews；
After the first stage for terminating renewal, because redaction application can access new database in the second stage of renewal, because
Data full dose in old database first can be synchronized in new database by this before the second stage of renewal is entered so that
The Various types of data in system is preserved in new database, the problem of being likely to occur unsuccessfully when preventing redaction application from accessing.
Then the second stage of renewal can be entered, as shown in b in Fig. 2.Both redaction is run during now system is equally
Using, legacy version application is run again, and in the second stage of renewal, legacy version application still conducts interviews to old database,
But now unlike the first stage of renewal, redaction application is now that new database is conducted interviews.Wherein, it is described new
Database is the database that redaction is applied in the network platform.
Redaction can be equally detected in the second stage of renewal using whether there is problem, if problem be present can repair
Change, then rerun, until terminating the second stage of renewal.
Step 103, terminate renewal second stage, and enter renewal phase III, while run redaction apply and
Legacy version application, redaction is applied in operation and legacy version is applied and new database is conducted interviews；
After the second stage for terminating renewal, the phase III of renewal can be entered, as shown in c in Fig. 2.Both run in system
Redaction application, legacy version application is run again.In the phase III of renewal, redaction application is still visited new database
Ask, but now unlike the second stage of renewal, legacy version is applied and new database is conducted interviews.
In the phase III of renewal, confirm that redaction application has no problem, can just terminate the of renewal after completing debugging
Three stages.
Step 104, at the end of the phase III of renewal, redaction application is run, redaction is applied to new data in operation
Storehouse conducts interviews.
After the phase III of renewal terminates, the renewal of application is completed, redaction application can formally reach the standard grade, you can be
Redaction application is only run in system, redaction is applied and new data is conducted interviews.
In summary, the embodiment of the present application divides what three phases were applied using when being updated in the network platform
Renewal, redaction is run in each stage simultaneously and is applied and legacy version application, but different phase is new, legacy version application accesses
Database it is different, can access old database or new database or access old database and new database.
Newly, it will not be limited when legacy version application accesses database, i.e., will not carry out lock table handling, therefore be not in using access
The failure problem of database, it can be ensured that the normal execution of business.
In the embodiment of the present application, the access can include read operation and write operation.In the first stage updated, new edition
This application and legacy version are applied carries out read operation and write operation to old database；In the second stage of renewal, redaction application pair
New database carries out read operation and write operation, and legacy version is applied carries out read operation and write operation to old database；The 3rd of renewal
In stage, redaction is applied and legacy version is applied and carries out read operation and write operation to new database.The phase III of renewal terminates
When, redaction application is run, redaction is applied in operation carries out read operation and write operation to new database.
Data are read in the read operation i.e. application from database, and the write operation is that application writes data into database.
Reference picture 3, give in the first stage updated described in the application preferred embodiment and apply to database access
Schematic diagram.
Refer to that redaction application is in systems run using issue, thus the first stage updated before application is issued, it is old
Version application is run in systems, and legacy version application is to carry out read operation and write operation to old database.
Before issue, the data source in system is old database, and the first stage updated is new using needs during issue
Database, therefore it is data source that can increase new database in systems.
Using issue when, redaction apply and legacy version application simultaneously runs in systems, now, redaction apply and it is old
Version application all carries out read operation and write operation to old database.When redaction fails using the read operation to old database,
Read operation is carried out to new database.
After issue, redaction application old database carries out read operation and write operation, when redaction is applied to legacy data
During the read operation failure in storehouse, read operation is carried out to new database, thereby may be ensured that reading data, traffic affecting is not held normally
OK.
In the first stage of renewal, if being detected after issue there is problem, it is necessary to debug in redaction application, can be in system
Middle execution rolling back action, i.e., system is returned to using the state before issue, because new, legacy version in preceding and issue is issued in application
Using all read operation and write operation is carried out to old database, i.e., redaction application and old edition during issue are preserved in old database
The data for the business that this application performs, therefore only need to carry out rollback to application in rolling back action, it is not necessary to database is carried out
Rollback.
In the first stage of renewal, it is not necessary to carry out the migration of data, redaction application can be detected in this process
Whether the link with new database is normal, and detects in new database whether be written with data then, is confirming that redaction should
With being connected with new database normally, and in new database after no data write-in, the first stage of renewal can be terminated.
Reference picture 4, give in the second stage updated described in the application preferred embodiment and apply to database access
Schematic diagram.
, can be by the number in old database into before the second stage of renewal after the first stage of renewal is terminated
It is synchronized to according to full dose in new database, i.e., by all data syn-chronizations in old database into new database.Also, in order to increase
The hit rate of historical data, it is ensured that data will not malfunction, and open old database and performed to the increment synchronization of new database, i.e. business
In can timing or in real time by the data syn-chronization in old database into new database.
In period of the first stage of renewal to the second stage for entering renewal is terminated, redaction out of service should
With what is run in system is legacy version application.
Into before the second stage of renewal, the database update that can access redaction application is new database.I.e.
Redaction applies the second stage in renewal to carry out read operation and write operation to new database.
In the second stage of renewal, before issue, legacy version application is run in system, now legacy version is applied to old number
Read operation and write operation are carried out according to storehouse, if legacy version fails using the read operation to old database, new database is read
Operation.
In the embodiment of the present application, the read operation unsuccessfully can be understood as business datum inquiry failure.In as discussed above,
For legacy version using the read operation failure to old database, i.e., legacy version is applied does not inquire data in old database, now may be used
To carry out read operation again in new database, i.e., the data are inquired about in new database, so that in new, old database
Data can be read, it is ensured that the normal execution of business.
Legacy version is run during using issue, in system simultaneously to apply and redaction application, wherein, legacy version is applied to old number
Read operation and write operation are carried out according to storehouse, redaction is applied carries out read operation and write operation to new database, still, when legacy version should
When being failed with the read operation to old database, read operation is carried out to new database；When redaction is using the reading behaviour to new database
When failing, read operation is carried out to old database., will not be to industry so as to may insure the successful execution of read operation by this method
Business causes.
The database that first progress read operation can be configured is default database, and the rear database for carrying out read operation is standby number
According to storehouse, that is, in the second stage updated, for legacy version application, old database is default database, and new database is standby
Database；For redaction application, new database is default database, and old database is standby database.Wherein, if business
Need to return the data of reading in 3s, then when being configurable in 1s not read data from default database, switch to from
Data are read in standby database.Therefore, the application can quickly read data, avoid traffic affecting from performing.
In the prior art, because old database is without write operation, it is necessary to increased from new database to old database
When measuring synchronous, the time of Data Migration is long, also may result in when data are read from old database, it is necessary to the long time
Result can be just got, compares and loses time.And the embodiment of the present application can solve this well and ask by above-mentioned method
Topic, will not cause waste of time, and ensure the execution of business, meet the needs of business.
, i.e., can be at 10 milliseconds to new, old database read operation by above method data query in actual treatment
Interior completion, processing speed is very fast, can support the execution of business, for example, the method described in the embodiment of the present application is applied
In the payment platform of ecommerce, the payment data of user can be quickly inquired about, the probability of malformed queries is reduced, meets business
Requirement for fast and accurately obtaining data.
After issue, redaction is applied carries out read operation and write operation to new database, when redaction is applied to new number
When failing according to the read operation in storehouse, read operation is carried out to old database.
In the second stage of renewal, if being detected after issue there is problem, it is necessary to debug in redaction application, can be in system
Middle execution rolling back action, i.e., system is returned to using the state before issue, because legacy version should before application issue and in issue
With read operation and write operation is all carried out to old database, i.e., legacy version is using the industry performed during issue is preserved in old database
The data of business, therefore only need to carry out rollback to application in rolling back action, it is not necessary to rollback is carried out to database.
It can detect whether redaction application has carried out writing behaviour to old database in the second stage of renewal, after issue
Make, and whether detect redaction normal using the read operation to new database and write operation.Confirming redaction using to new
The access of database is normal, i.e. read operation and write operation is normal, and redaction apply to old database without write operation after, Ke Yijie
Shu Gengxin second stage.
Reference picture 5, give in the phase III updated described in the application preferred embodiment and apply to database access
Schematic diagram.
In period of the second stage of renewal to the phase III trial operation for entering renewal is terminated, new edition out of service
This application, what is run in system is legacy version application.
Before the phase III of renewal is entered, the database update that can access legacy version application is new database,
I.e. legacy version is applied carries out read operation and write operation to new database.
In the phase III of renewal, before issue, legacy version application is run in system, now legacy version is applied to new number
Read operation and write operation are carried out according to storehouse, when legacy version fails using the read operation to new database, old database is read
Operation.
Using in issue, legacy version application and redaction application all carry out read operation and write operation to new database, when old
When version fails using the read operation to new database, read operation is carried out to old database.Equally, can be quick by this method
Reading data, ensure the normal execution of business.
After issue, redaction application all carries out read operation and write operation to new database.
In the second stage of renewal, if being detected after issue there is problem, it is necessary to debug in redaction application, can be in system
Middle execution rolling back action, i.e., system is returned to using the state before issue, because legacy version should before application issue and in issue
With read operation and write operation is all carried out to new database, i.e., legacy version is using the industry performed during issue is preserved in new database
The data of business, therefore only need to carry out rollback to application in rolling back action, it is not necessary to rollback is carried out to database.
Can be detected in the second stage of renewal, after issue redaction application whether do not have to old database read operation and
Write operation, and detect redaction and apply with old database with the presence or absence of link.Apply in confirmation redaction and do not have to old database
Have a read operation and write operation, and redaction apply and old database without link after, terminate phase III of renewal.
After the phase III of renewal terminates, after confirming that redaction application has no problem, the offline of old database can be carried out
Processing, i.e., will delete old database in the data source of system, during which, it is necessary to carry out data backup, the tables of data in old database
Renaming etc. operates, and then continuous observation for a period of time, can be formal after confirming that redaction application runs no problem in systems
Redaction application is run, terminates the operation of legacy version application in systems.
In summary, in the prior art because old database is without write operation, it is necessary to from new database to legacy data
When storehouse carries out increment synchronization, the time of Data Migration is long, also may result in when data are read from old database, it is necessary to compare
The long time can just get result, compare and lose time.And in the embodiment of the present application, should in the first stage redaction of renewal
Read operation is can be carried out with to new, old database；In the second stage of renewal, new, legacy version is applied to new, old database all
Read operation can be carried out；Applied in the phase III legacy version of renewal and read operation can be carried out to new, old database.By upper
State method so that, can also be from another when application reads data failure from a database even if the Data Migration time is long
Read in one database, so as to quickly read data, do not interfere with the execution of business.
