Specific embodiment
To keep the purposes, technical schemes and advantages of the application clearer, below in conjunction with the application specific embodiment and
Technical scheme is clearly and completely described in corresponding attached drawing.Obviously, described embodiment is only the application one
Section Example, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not doing
Every other embodiment obtained under the premise of creative work out, shall fall in the protection scope of this application.
Below in conjunction with attached drawing, the technical scheme provided by various embodiments of the present application will be described in detail.
Embodiment 1
As previously mentioned, the application system of Internet service needs to be migrated according to different needs, for example, being to application
Application program or hardware device in system carry out upgrade maintenance etc., require the function that original application system provides moving to mesh
It marks in application system.When carrying out application system migration, can target application system reach desired effect, be in migration work
The importance of concern.In practical applications, Internet service generally is carried by more hardware devices, for example, there are 1000 clothes
Be engaged in device equipment processing line on user service request, if necessary to one of this 1000 server apparatus application program into
Row upgrading.One of part server application program can be upgraded in batches, to realize to using system migration
Test, still, if target application system is unable to reach desired effect, it is possible to make troubles (ratio for user on line
Such as, there is mistake etc. in processing business request).So can by target application system it is online under to original application system processing
The service request crossed is handled again, the place requested by comparison target application system and original application system identical services
Reason is as a result, realize the test to application system migration.If there is the business of user on 1000 server apparatus processing lines to ask
It asks, for one day (24 hours), this 1000 server apparatus can handle 200,000,000 service requests, this 200,000,000 service request packets
Different types of business (business source difference, type of service difference etc.) is included, however, for lower test application system migration online
Property server apparatus, no matter from cost consideration, or from resource utilization consider, same number has been impossible to, if only
This 200,000,000 service requests are handled with 10 server apparatus, often consume the extra 24 hours time, which results in migrations
Property test efficiency it is lower；If choosing a part from 200,000,000 service requests to be handled, although can be no more than on the time
24 hours, but it is possible that miss some types of business, service coverage face is reduced, to influence migration test
Accuracy.In order to improve the efficiency of migration test under the premise of ensuring the accuracy of migration test, the present embodiment provides
A kind of test method of application system migration.The idiographic flow schematic diagram of this method is as shown in Figure 1, include the following steps:
Step 11, the processed service request of original application system is obtained.
For step 11, the processed service request of original application system and processing result are often stored in
In business diary, by obtaining business diary, so that it may get the processed service request of original application system.For example, meeting
Wired upper log, the processing result for saving service request on line and to business on line can be come by different interfaces
Obtain the log for saving business on different types of line.
Step 12, service request is clustered, forms at least two cluster set, the service request tool in cluster set
There is similar property.
Cluster, refers to the process of that the set by physics or abstract object is divided into the multiple set being made of similar object.
By clustering the set that cluster set generated is a group objects, these objects cluster the phase each other of the object in gathering with same
Seemingly, different with the object in other cluster set.
It follows that the process of cluster, practical is exactly that the object with similar quality is formed to a cluster set.At this
In embodiment, the process of cluster, a cluster set will be formed with the service request of similar property by referring to.
For service request, the service feature wherein included with cluster correlation, can as the foundation clustered,
So can first filter out the noise number for including in service request after obtaining the processed service request of original application system
According to (i.e. the service feature unrelated with cluster), for example, the remark information that user adds in service request, the time letter of service request
Breath, for remark information due to being user oneself addition, temporal information is that system is generated according to the current time for receiving service request
, cluster result is not influenced, so filtering out noise data, computing resource can be not only saved in cluster process,
More importantly there is not interference to the accuracy of cluster.
For step 12, there can be following sub-steps:
Sub-step 121, the service feature progress feature extraction with cluster correlation to including in service request.
The service feature for including in service request, there are some unique identifications, for example, business serial number (must be unique
), user identifier (each user has unique mark).These unique identifications be also have similar quality (although such as business
Serial number is different, but belongs to identical services type), but if clustered using unique identification, cluster certainly will be will affect
As a result (identical services, if on the time differ it is more, business serial number also can be mutually far short of what is expected), it is therefore desirable to cluster correlation
Service feature carry out feature extraction.
The service feature progress feature extraction with cluster correlation to including in service request, may include following at least one
Kind:
To the operational feature extraction character string digit with cluster correlation for including in service request；
To the type feature extraction alphabet with cluster correlation for including in service request；
To the positive negativity of numerical characteristics extraction with cluster correlation for including in service request.
Specifically,
Operational feature may include: business serial number, user identifier etc., and generally, business serial number is according to business kind
Class, the current time for receiving service request etc., the character string generated by application system, the character string are unique, so, with
Character string of business serial number itself obviously will affect cluster result as the foundation of cluster；Likewise, each user is corresponding
User identifier is also that uniquely, the foundation using character string of user identifier itself as cluster obviously also will affect cluster result.
So the digit of character string can be extracted for type feature, the foundation as cluster.
Type feature may include: service condition, type of service, business source etc., and generally, type of service, business are come
Source etc., is all preset, changeless code name, and service condition is the label that application system is generated according to performance.Such as:
Payment transaction 010001, transferred account service 010002；The end PC business pc, mobile terminal service mobile；It initializes I, success S, lose
Lose F etc..These character strings all can serve as the foundation of cluster.So alphabet can be extracted for operational feature.
Numerical characteristics may include: the quantity in service request, and generally, the quantity in service request is asked according to business
What the quantity in asking generated, such as 10 (supplementing 10 game moneys with money), -2 (consumption 2) etc..These character strings itself are as cluster
Foundation be nonsensical, but represented positive negativity is meaningful, so, for numerical characteristics, can extract just
Negativity.For example 0,1,2 respectively indicate 0, negative, positive number.
Sub-step 122 determines the cluster centre of specified quantity.
Before starting to service request cluster, at least two cluster centres can be first determined, so as to by service request
It is clustered, forms at least two cluster set.
The cluster centre for determining specified quantity may include:
According to the service feature with cluster correlation for including in service request, specified quantity cluster centre is determined；Or
According to processing capacity of the target application system within the unit time, specified quantity cluster centre is determined.
Specifically,
The meaning of cluster is to cluster the service request with similar property, forms cluster and gathers, and business
It is including in request that the foundation whether with similar property is exactly distinguished with cluster correlation service feature, it is possible to root
According to these service features, to determine the cluster centre of specified quantity.For example, can be according to the business flowing water in operational feature
Number, user identifier, service condition, type of service, business source in type feature, the positive negativity of numerical characteristics is combined,
Determine the cluster centre of specified quantity.
During test application system migration, the time limit (1 day, 1 week) of a test is had, in order to limited
In time, cover service coverage face wide as far as possible, target application system can be calculated according to the following equation in the unit time
Interior processing capacity:
K=n/t × T；Wherein, n indicates the n service request that the processing of target application system is completed, and t indicates target application system
The time-consuming of n service request is completed in system processing, and T represents the time limit of test；K indicates target application system in T time section most
Big processing quantity.
For example, 1 server apparatus 1 second, 1000 service requests have been handled, then the server apparatus was at 24 hours
Interior maximum processing quantity are as follows: 1000/1 × 24 × 60 × 60=8640000 (item)
Sub-step 123 clusters service request according to feature extraction result at a distance from cluster centre.
The poly- of number of executions is defined after having obtained feature extraction after executing sub-step 121 as a result, executing sub-step 122
Class center, so that it may according to feature extraction result at a distance from cluster centre, service request cluster.
According to feature extraction result at a distance from cluster centre, service request is clustered, may include:
The alphabet extracted is calculated at a distance from cluster centre using Hamming distance；
The character string digit extracted and positive negativity are calculated at a distance from cluster centre using standard Euclidean distance；
According to calculated at a distance from cluster centre, the service request is clustered.
Specifically, Hamming distance refers to the character that a character string is transformed into replacement required for another character string
Number.Such as:
Hamming distance between 010001 and 010002 is 1；
Hamming distance between 4007 and 3008 is 2.
The by the agency of in sub-step 121, type of service, business source etc. in type feature, are all preset, fixed
Constant code name, service condition are the labels that application system is generated according to performance.Such as: payment transaction 010001 is transferred accounts
Business 010002；The end PC business pc, mobile terminal service mobile；Initialize I, success S, failure F etc..These type features are all
It is fixed and invariable, it is possible to which the alphabet extracted is calculated at a distance from cluster centre by Hamming distance.
Calculating the alphabet extracted using Hamming distance can calculate at a distance from cluster centre according to following formula:
M1=(x1x2x3…xn), M2=(y1y2y3…yn), define calculating formula of similarity:
Wherein xk, ykRespectively indicate M1And M2In k-th of component or be 1 or be 0,For mould two plus operation, M1With M2
One of them is the feature for the cluster centre determined.
For example, can determine that the type of service of cluster centre is payment transaction 010001, the service class of a certain service request
Type is transferred account service 010002, then n=6；x1=x3=x4=x5=0, x2=x6=1；y1=y3=y4=y5=0, y2=1, y6
=2, sim=1-1/6=0.83.
The same by the agency of in sub-step 121, business serial number, user identifier in operational feature, extracts character string
Digit.The quantity in service request in numerical characteristics, extracts positive negativity.Service request can be represented due to extracting result
Property, it is possible to by standard European distance calculate the character string digit that extracts and positive negativity and cluster centre away from
From.
Two 1 (x of n-dimensional vector11, x12…x1n) and 2 (x21, x22…x2n) between standardization Euclidean distance formula:
Wherein, SkFor the standard deviation of component k, such as k=1, S1For x11With x21Standard deviation.
Finally, being clustered at a distance from cluster centre to service request according to calculated.
It specifically, can be according to calculated at a distance from cluster centre and preset distance threshold, to service request
It is clustered.
Step 12 clusters service request, makes according to the service feature with cluster correlation for including in service request
Service request with similar quality forms a cluster set.In practical applications, different business scenarios can be formed
Several cluster set.
Step 13, a certain number of service requests are chosen respectively from each cluster set, select from each cluster set
Total number of the quantity of the service request taken less than the service request that each cluster set includes.
Each cluster set all has different property, and step 13 is the meaning of the selection mode of service request,
On the one hand, the result of selection covers a variety of different properties, misses caused by solving after there is arbitrarily choosing a part
The service request of property.On the other hand, under the premise of meeting the requirement for covering a variety of different properties, the quantity selected becomes
It is few, it solves the problems, such as all to choose the substantial amounts occurred；So the service request selected by executing step 13, both may be used
To meet the requirement for covering a variety of different properties, there is the demand that can satisfy less service request quantity.
Step 14, it is handled, is realized to using system migration using service request of the target application system to selection
Test.
After target application system handles the service request of selection, obtained processing result can be with primal system
After handling the service request of selection, obtained processing result is compared, to realize the survey to application system migration
Examination.The purpose of test, can not only know target application system whether meet migration after the needs of；Target system can also be tested out
The problem of system.For example, target application system have the defects that it is certain, so that it may utilize method provided in this embodiment, test out
The specific location of defect；Application program in target application system has upgrading, so that it may method provided in this embodiment is utilized,
Whether the application program after testing out upgrading meets the expectation for upgrading.
This method provided using embodiment 1 is obtaining original application system in the test process of application system migration
It unites after processed service request, first service request is clustered, form at least two cluster set with similar quality,
The total number for choosing the service request for including less than each cluster set from each cluster set again, is finally answered using target
It is handled with service request of the system to selection, realizes the test to application system migration.How to choose service request is
The key of testing efficiency is improved, in this application, the service request selected using cluster meets covering wide as far as possible
Face requires, and meets the demand for reducing test quantity.On the one hand, it avoids and all processes whole service requests, and only locate
Manage a part of service request, the promotion of bring testing efficiency；On the other hand, business of different nature can as often as possible be covered
