Description
Technical field
Embodiments of the invention relate generally to computer software, more particularly, to the side for safeguarding software systems
Method and equipment.
Background technology
After software systems are developed and are disposed, the software systems in safeguard with being one important asks
Topic.Fault diagnosis is carried out to operating software systems and maintenance generally requires to spend substantial amounts of human and material resources and time.Mesh
Before, it is known that software systems maintenance strategy can generally be divided into two classes.First kind maintenance strategy is training and assigned special
Technical staff, by these technicians by substantially it is complete it is artificial in a manner of be responsible for particular software product failure solve and safeguard.
Second class maintenance strategy is structure knowledge base, so as to technical staff or terminal user when encountering problems can quick-searching be directed to
The solution stored of problems.
For first kind strategy, main problem is that：Training one has experience and higher professional technical merit
Professional generally requires to devote a tremendous amount of time and cost.For the second class strategy, main challenge come from how
Establish effective issue database, the information that match pattern is defined and collected for schema evolution.Such as Microsoft
Windows some systems use error code and some predefined critical datas.However, occur after software systems issue
Many problems often happen suddenly and it is unknown, can not software systems design, realization and/or test phase predict.For
The problem of such, generally it can not provide accurate failure cause and solution by the simple retrieval to existing knowledge base and matching
Scheme.
At present, most KBS Knowledge Based Systems are based only on the presentation of mistake/problem or symptom is looked into knowledge base
Ask, and by search for such as journal file etc record come provide it is man-to-man mapping (in some advanced systems may
There is provided many-one mapping).In this scheme, end user is typically only capable to obtain the suggestion of an issue-resolution.But
It is appreciated that in software systems there is the problem of identical presentation to be likely to as caused by different root cause problems.For example, big
In type storage system, existing factor may cause " user cannot connect to particular memory array " this image of problem.The opposing party
Face, the same root cause problems in software systems may have different presentations under different service conditions and state.In these feelings
Under condition, there is provided single solution suggestion is insufficient.Moreover, because go together in the prior art can not effectively more
New knowledge base, therefore user has found and solved the problems, such as often be used for reference by other users in use.
Therefore, the problem of more effectively building for software systems fault diagnosis and safeguard there is a need in the art for one kind number
According to the scheme in storehouse.
The content of the invention
In view of the above problems, the present invention proposes a kind of method and equipment for maintaining a software system.

The problem of in thesaurus described in the feedback updated of at least one potential root pattern.
In the second aspect of the present invention, there is provided a kind of method for safeguarding software systems, the example of the software systems
It is deployed at least one client.Methods described includes：The target occurred in the software systems is sent in server
The presentation of problem；Receive from the server and obtained and the target problem phase by the server by inquiring about thesaurus
At least one potential root of association；Whether the root for determining the target problem is one of described at least one potential root；
And determine to provide the feedback for being directed at least one potential root to the server according to described, for the storage
The problem of in storehouse pattern renewal.
In the third aspect of the present invention, there is provided a kind of equipment for safeguarding software systems, the example of the software systems
It is deployed at least one client.The equipment includes：Reception device, it is configured to terminate from least one client
Receive the presentation of the target problem occurred in the software systems；Inquiry unit, it is configured to ask using presentation inquiry storage
The thesaurus of topic pattern is each in the thesaurus to obtain at least one potential root associated with the target problem
Described problem pattern indicates the root and presentation of a known problem of the software systems；Dispensing device, it is configured to institute
State at least one potential root and be sent at least one client；And updating device, it is configured to according to for described
The problem of in thesaurus described in the feedback updated of at least one potential root pattern.
In the fourth aspect of the present invention, a kind of equipment for safeguarding software systems, the example of the software systems is by portion
Administration is at least one client.The equipment includes：Dispensing device, it is configured to be sent in the software systems to server
The presentation of the target problem of middle appearance；Reception device, it is configured to pass through inquiry from server reception by the server
Thesaurus and at least one potential root associated with the target problem obtained；Determining device, it is configured to determine institute
Whether the root for stating target problem is one of described at least one potential root；And feedback device, it is configured to according to
It is determined that the feedback at least one potential root is provided to the server, mould the problem of in the thesaurus
The renewal of formula.
It will be understood that by being described below, according to an embodiment of the invention, it is allowed to which each of software systems example is installed
The presentation (for example, journal file) of problem is submitted to server by client when problem or failure occur for software systems.Service
The priori question mode on software systems is stored with the thesaurus of device.Especially, according to an embodiment of the invention, database
The problem of middle storage pattern can only comprising software systems problem part presentation (for example, by compared with multi-user in journal file
The partial entry of concern), and the part is determined according to the notes and commentary or discussion of user.
According to an embodiment of the invention, server will return to the potential root of more than one to client, rather than as existing
Single root is returned only in technology like that.If the user determine that the potential root that the root of current problem, which is server, to be provided it
One, user can be made commentary and annotation to target problem (for example, he/her thinks important some presentations) or be begged for other users
By, and server is submitted to further enhance existing question mode.On the other hand, if the user determine that server returns
The potential root returned is not consistent with current software systems produced problem, then user can manually or otherwise study simultaneously
Determine root.Now, user can be by the root of its determination, his notes and commentary to image of problem and/or the solution for the problem
Scheme returns to server, to create new pattern in the thesaurus of server.
In this way, server no longer returns to a root only according to presentation as in the state of the art, and is to provide
Multiple possible roots confirm for user.Moreover, knowledge base can dynamically be updated based on user feedback in use, so as to carry
The intelligent and accuracy of high subsequent software system maintenance.

Embodiment
Some exemplary embodiments shown in below with reference to the accompanying drawings come describe the present invention principle and spirit.It should manage
Solution, these embodiments are provided just for the sake of better understood when those skilled in the art and then realize the present invention, and simultaneously
The non-scope limiting the invention in any way.
With reference first to Fig. 1, it illustrates the method 100 according to an embodiment of the invention for being used to safeguard software systems
Flow chart.According to an embodiment of the invention, the example of software systems can be deployed on one or more clients, and these
The server communication that client can be safeguarded by network or any other appropriate communication mechanism with responsible software systems.Scheming
The example of the method 100 shown in 1 for example may operate on server.
After method 100 starts, in step S102, the target occurred in software systems is received from least one client and is asked
The presentation of topic.
It is appreciated that during the example of software systems is run on the client, it is possible that problem or event
During barrier.Now, the presentation of problem or failure can be sent to server by client.Term " target problem " as used herein
Refer to that client is current of interest and aim to solve the problem that software systems the problem of, failure or need user to give attention and solve
Any other affairs.In addition, term " presentation " as used herein refers to the description to the symptom of target problem, such as including asking
The time of occurrence of topic, the form of expression, system mode when there is the problem, the system action triggered, software systems context, etc.
Deng.Presentation can be textual form or multimedia or Rich Media's form.
According to certain embodiments of the present invention, the presentation of target problem for example can be in the running of software systems
Caused log information.For example, the presentation of a problem can be software systems at the time of the problem occurs or to timing
The log information generated during section.Such log information can be for example stored in special journal file, naturally it is also possible to protected
Exist in database or other appropriate data storage mediums.It is appreciated that log information is generally by a series of journal entries
Composition.Each journal entries can include one or more fields for recording different types information.As an example, lower expression
The structure of the journal entries of a possible software systems is gone out.
| Grade | Time | Event | Description | Classification | Source | Type |
Pay attention to, what structure illustrated above was merely exemplary, for logging software system behavior and problem it is any
It is log-structured to all fall within the scope of the present invention.Moreover, in addition to log information or as supplement, other can be stored
The problem of form presentation.For example, what the user that the presentation of the problem of in software systems can include client inputted manually
Text, image or voice description, etc..Other any possible presentations are also what is be contemplated that, and the scope of the present invention is herein
Aspect is unrestricted.
Especially, according to an embodiment of the invention, it is allowed to which the user of client is some to the target problems of software systems
Presentation (for example, some journal entries) addition notes and commentary and discussion.These notes and commentary and discussion can be together with image of problems in step
S202 being serviceds device receives.This also will be discussed in.
According to an embodiment of the invention, in step S102, server can utilize various appropriate communication mechanisms from least
One client receives the presentation of target problem.For example, the connection mechanism between server and client can include wired network
Network, wireless network or its combination, include but is not limited to following at least one：Cellular phone network, Ethernet, based on IEEE
802.11st, 802.16,802.20 etc. WLAN (WLAN), and/or World Interoperability for Microwave Access, WiMax (WiMAX) net
Network.In addition, connection medium can be public network (such as, internet), dedicated network (such as, intranet) or its group
Close.Alternatively or additionally, connection medium can also be the equipment of interconnection and communication between the user equipmenies such as bus.As special case,
With client location on identical physical machine, if communication therebetween can also include inside machine server
Communication mechanism, such as bus communication or interprocess communication, etc..The scope of the present invention is not limited in this respect.
Next, method 100 proceeds to step S104, the presentation in the step S102 target problems received is utilized herein
Thesaurus is inquired about, to obtain at least one potential root associated with the target problem.
According to an embodiment of the invention, safeguard there is one or more thesaurus or knowledge base in server-side.Storage
Storehouse can be any appropriate memory mechanism that can be configured to data storage and information.It is stored with thesaurus for software system
The problem of priori of system pattern.According to an embodiment of the invention, question mode can be pre-established and stored, and can be with
Dynamic updates and learnt in use.Each question mode is used for the root and table for indicating a known problem of the software systems
As.For example, the following table shows an example arrangement of pattern the problem of storage in thesaurus.Pay attention to, structure shown below
It is merely exemplary.Question mode can also include other optional information, for example, the problem solution (for example, by
Sequence of operations form), time of origin, condition, frequency, determine root user mark, etc..
| Root | Image of problem |
As described above, in certain embodiments of the present invention, the presentation of a problem can be the problem associated day
Will information.Now, " image of problem " field of each question mode in thesaurus can include related to a known problem
A series of log information (for example, journal entries) of connection." root " field can include the root for causing the problem after diagnosing
This reason.
Especially, all tables associated with the problem can be included for each question mode, " image of problem " field
As, such as the caused All Log Entries within the given period.However, it is to be appreciated that different presentations is for decision problem
There may be different importance for root.For example, some journal entries are the key factors of decision problem root, and it is another
It is a little then possible unimportant.Therefore, according to some embodiments of the present invention, the problem of in thesaurus pattern can only include with
The associated part of problem and not all presentation (for example, being considered as important part presentation).
It is as outlined above and will be discussed in, according to an embodiment of the invention, it is allowed to one or more clients
Presentation (for example, entry of journal file) addition of the user at end to problem is made commentary and annotation, annotates and/or discussed.One rationally
Hypothesis be：Obtain most users concern or the crucial table that those important presentations are the problems is explicitly designated as by user
As.On the contrary, few user's evaluations or user are designated as the non-key presentation that those unessential performances are then the problems.This
Sample, can be based on the table on some software issue collected in advance from multiple client according to certain embodiments of the present invention
As (being referred to as sample), important presentation in therefrom being extracted by machine learning or pattern-recognition.The pattern the problem the problem of
In (such as in " image of problem " field being illustrated above), it will only preserve these important presentations.Those skilled in the art can
To understand, various machine learning methods can be used in combination with embodiments of the invention, for example, Bayesian model, neutral net,
Markov model, SVMs, etc..
In this way, according to certain embodiments of the present invention, pattern need not preserve each problem the problem of in thesaurus
All presentations, but the pith of the presentation extracted according to user annotation.So not only contribute to save memory space,
More importantly, the potential root of target problem can be more precisely identified in subsequent query and matching operation.This is also
It will be discussed in.
, can be by the target problem presentation that sends user according to some embodiments with continued reference to Fig. 1 step S104
Matched with the presentation indicated by each question mode in database to determine the potential root of target problem.For example, can
With using the word description of presentation carry out text matches, so as to find out with current target problem presentation in terms of word description most
For problem known to similar one or more.Specifically, if same or analogous word description (example in two presentations
Such as, same or analogous journal entries) it is more, then it is assumed that and two problems are similar all the more, and then are more possible to identical root
Source.In this way, it is possible to the root of the known problem similar to target problem will be confirmed as potential of target problem
Source.It is appreciated that in such embodiments, by as described above by inessential or not crucial presentation from thesaurus
Excluded in image of problem, it will help matching noise is excluded, so as to find the known problem more matched.
Moreover, during being matched to image of problem, user added those presentations of notes and commentary (for example, daily record
Entry) there can be higher weight.That is, if such presentation matches, then it is assumed that the probability that two problems are mutually matched
Also it is higher.
It should be noted that be merely exemplary by characters matching to inquire about thesaurus.Other feasible realities in this respect
Example is applied to be described in detail below with regard to Fig. 2.
Especially, it can be seen that potential of more than one can be obtained at step S104 unlike the prior art
Source, but obtain multiple potential roots or candidate's root that may be related to target problem.So, user can be bigger
In the range of checking and determine target problem root.
Next, method 100 proceeds to step S106, herein by least one potential root be sent to it is described at least
One client.Alternatively, in step S106, the solution corresponding with each potential root can also be sent jointly to
Client.For example, solution can be a series of sequences acted in order.
As described below, after potential root is received, the user of client can determine server provided to
Whether a few potential root is the root of target problem, and provides corresponding feedback.Moreover, if solution is in company with latent
There is provided together in root and arrived client, then client user can perform action according to solution, to solve target
Problem.This is described in detail below with regard to Fig. 3 and Fig. 4.
Server can then be deposited at step S108 according to the feedback updated at least one potential root
The problem of in bank pattern.According to an embodiment of the invention, unlike the prior art, server provides target to client
The potential root of problem is not the termination of service.On the contrary, client can provide feedback to indicate what is provided to server
Whether at least one potential root contains the true root of target problem.
For example, if the server determine that at least one potential root contain the true root of target problem, then client
End alternatively can be provided for various information such as the notes and commentary, ranking, discussion of image of problem (as described above, user to server
The presentation of addition notes and commentary is often important).Thus, server can be utilized in these information updatings and adjustment thesaurus
Corresponding question mode so that follow-up inquiry and service are more intelligent.
On the other hand, if the user of client determines that the potential root that server is provided does not include target problem
True root, then user voluntarily can study and determine the root of the problem and be returned to server.Alternatively, client
Notes and commentary for some major issue presentations can also be provided to server.Thus, server can create in storage and
Preserve the problem of new pattern.
Method 100 terminates after step S108 is completed.
By performing method 100, when problem occurs for the software systems example of client, server can carry to client
For the potential root of more than one；And with the propulsion of service, thesaurus can obtain constantly, adaptively update with it is complete
It is kind, so as to adjust existing question mode and/or create the problem of new pattern.Compared with prior art, this can be significantly improved
The intelligent and accuracy that software systems are safeguarded.
Below with reference to Fig. 2, it illustrates the side for being used to safeguard software systems according to another exemplary embodiment of the present invention
The flow chart of method 200.Pay attention to, method 200 is considered a specific implementation of the method 100 above with reference to Fig. 1 descriptions.
After method 200 starts, at step S202, receive in software systems from least one client by server
The log information of the problem of existing.In other words, in the embodiment of method 200, image of problem exists in the form of log information.
Next, method 200 proceeds to step S204, the log information by will be received from least one client herein
With in the thesaurus of server store the problem of pattern log information matched, come determine it is associated with target problem extremely
A few potential root.
According to an embodiment of the invention, for each question mode stored in thesaurus, it can be calculated and asked with target
Matching degree between topic.As described above, a kind of exemplary approach for calculating matching degree is to be based on text matches.That is, by mesh
The journal entries indicated in journal entries and question mode that the log information of mark problem is included are contrasted.If one
Know that the journal entries of journal entries possessed by problem and target problem are close enough, then it is assumed that the known problem and target problem
It is mutually matched.
Alternatively or additionally, the matching journey between two problems can also be determined using Bayes's (Bayes) formula
Degree.As an example, each question mode in thesaurus can be considered as to a record, and utilize following Bayes
Formula is come problem known to determining and received from the matching degree between client objectives problem：
Wherein P (RCi|sympj) be in thesaurus under presentation j have root i probability, P (sympj|RCi) it is storage
There is presentation j probability, P (RC in storehouse under root ii) it is the probability for occurring root i in thesaurus, P (sympj) it is thesaurus
The middle probability for presentation j occur, Scorepattenmatch(sympj, RCi) it is pattern matching score, Num (sympj|RCi) it is thesaurus
In under root i with phenomenon j record number, Num (sympj) sum of the record with presentation j, Num in thesaurus
(RCi) be in thesaurus with root i record sum.Thus, it is possible to calculate each known problem in thesaurus with
The score of matching degree between the target problem received from client.
It should be appreciated that what above-described several embodiments were merely exemplary.According to an embodiment of the invention, Ke Yili
With any proper technology for being currently known or developing in the future, problem-targeted presentation is come qualitative or quantitatively determined from client
Hold the matching degree between the known problem stored in the target problem and thesaurus received.The scope of the present invention is in this regard not
It is restricted.
Certain number of known problem can be selected according to matching degree, the problem of these are known is considered as and target problem
It is potentially similar or close.For example, matching degree can be selected higher than the known problem of predetermined threshold；Or it can select
With problem known to degree highest top n (N is natural number).Correspondingly, the root so by matching selected known problem
Source can be determined that the potential root of target problem.
Next, method 200 proceeds to step S206, by least one latent of the target problem obtained by step S204
Client is sent in root.In some embodiments it is possible to according to target problem and known problem (and thus with it is corresponding
Potential root) between matching degree, by least one potential root arrangement obtained in lists.At step S206,
The list is sent at least one client.
Next, at step S208, the feedback for transmitted at least one potential root is received from client, is entered
And determine whether the actual root of target problem is that server is obtained and sent at least according to the feedback at step S210
One of one potential root.
Following article will combine what Fig. 3 and Fig. 4 was described in detail, according to an embodiment of the invention, if the user determine that target problem
Root is one of at least one potential root that server provides, and client may be configured to indicate to server in feedback
This point.Now, method 200 proceeds to step S212 (along branch's "Yes" at step S210).
In step S212, server can receive selection of the user at least one potential root from client.That is, client
The user at end can indicate which specific potential root is the actual root of target problem.For example, this can be by using mouse
The marking toolses such as mark click on the specific potential root in list to realize.Certainly, other any appropriate interactive modes be also can
Capable.Client by one of user's instruction specific potential root (that is, the actual root of target problem) it is possible thereby to return to clothes
Business device.
Pay attention to, while shown as two steps, but actually step S212 can be contained in step S210.Change speech
It, user can be indicated by selecting this action of a specific potential root in potential root list to server
The root of target problem is one of potential root, and which potential root also indicates is.Now, step S210 and S212 can
To complete in one step.Therefore, the step division in Fig. 2 is clear just for the sake of in logic.
Next, method 200 proceeds to step S214, the user annotation for target problem is received herein.According to this hair
Bright embodiment, the user of client are allowed to make commentary and annotation to target problem.According to some embodiments, user can utilize visitor
The various instruments that family end provides increase notes and commentary on target problem, notes and commentary can for example be related to problem some presentations (for example,
Some journal entries), the particular problem that is run into during solving the problems, such as, the path for solving the problem, need especially to close
Solution action of note, etc..
, can be with when sending potential root to client at step S206 in addition, according to certain embodiments of the present invention
The previous user notes and commentary for each potential root stored in thesaurus are sent simultaneously.In such embodiments, client
User can change previous user notes and commentary, to previously notes and commentary addition annotation and/or delete previously notes and commentary (certainly, this deletion
It may need to be limited by Permission Constraints.As an example, in certain embodiments, user is restricted to that his/her can only be deleted
The notes and commentary previously added).
In addition, according to an embodiment of the invention, the door (portal) dedicated for software maintenance, its shape can be provided with
Formula is, for example, the zone of discussion based on web, message board, social networking website, blog, microblogging, etc..The user of different clients can
To be discussed by the door to the problem of software systems, the action such as ranking.In step S214, server can from door or
Other clients receive the information on such action.
Next, method 200 proceeds to step S216, utilize herein step S214 receive for target problem
User annotation, change the problem of associated with that potential root that the user received step S212 at selects in thesaurus mould
Formula.For example, with the addition of notes and commentary and the presentation (for example, journal entries) discussed for user, it is believed that its importance is higher, from
And increase weight of these presentations in (step S204) is matched.Correspondingly, user pays close attention to those less presentations in matching
Weight will reduce, or even from question mode be removed.Especially, as described above, according to certain embodiments of the present invention, deposit
The problem of in bank, pattern can extract by learning and training from known sample.Correspondingly, in step S216, Ke Yili
Re -training is carried out to question mode with the user annotation received at step S214, so as to improve the intelligent of follow-up service.Side
Method 200 terminates after step S216.
Return to step S210, if the root of the feedback instruction target problem of client is not the multiple of server offer
Any one (branch's "No") in potential root, method 200 carry out step S218.In step S218, receive by client
The root for the target problem that user determines.Alternatively, the notes and commentary that user is directed to target problem can also be received at step S220,
These notes and commentary are similar to above with reference to described by step S214.
Next, in step S222, the root of the target problem explicitly indicated by user can be utilized (to be connect in step S218
Receive), the presentation of target problem (being received in step S202), and alternatively also have the user annotation for target problem (in step
Rapid S220 is received), the new problem pattern associated with the target problem and root is created in storage.In this way, may be used
It is dynamically added to the new problem found during software systems are run in the knowledge base of backstage, so as to improve follow-up maintenance service
Quality.Method 200 terminates after step S222.
Two of method being used for software systems and safeguarding in server-side are described by reference to Fig. 1 and Fig. 2 above
Specific embodiment.Below with reference to Fig. 3, it illustrates being used in client-side according to an illustrative embodiment of the invention
The method for safeguarding the method 300 of software systems.
As shown in figure 3, in step S302, when the software systems of client go wrong and (are referred to as target problem), client
The user at end can indicate that user end to server sends the presentation of produced problem in software systems." user " mentioned here
Can be that client is responsible for the engineer that software systems are safeguarded, and/or terminal user of software systems, etc..In addition, as above institute
State, " presentation " of target problem refers to the description to the symptom of target problem, such as the appearance form including problem, trigger be
System state, system action, time of origin, system context, etc..Especially, can be presented as according to some embodiments, presentation
The log information of software systems.Moreover, according to certain embodiments of the present invention, it is allowed to which user adds to presentation and commented, and will
These are commented together is sent to server in company with presentation.
Next, in step S304, at least one potential root associated with target problem is received from server, these
Potential root is to be stored with the thesaurus of question mode to obtain, as described above by inquiry by server.For example, these
Potential root can be determined according to server with the matching degree of target problem and be organized in list.
In step S306, whether the root for determining target problem is one of described at least one potential root.For example, client
The user at end carries out investigating and analyzing one by one with reference to current systemic symptom and state to potential root, determines whether have
The actual root of current goal problem.
In step S308, the feedback at least one potential root is provided to server, for renewal server
Thesaurus.Specifically, client can generate feedback message according to the operation of user, indicate target problem root whether
One of at least one potential root sent for server.Alternatively, client can also obtain user for target problem
Notes and commentary.These feedbacks can also be sent to server, pattern the problem of so as in server update or newly-built thesaurus, as above
Described in literary reference chart 1 and Fig. 2.
Method 300 terminates after step S308.
By method 300, user can not only be obtained one or more potential by uploading image of problem to server
The list of root, and feedback is made in the list that can be returned to server, so as to support the dynamic of server end knowledge base more
