Specific embodiment
Purpose, technical scheme and advantage to make the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention
In attached drawing, the technical solution in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
The part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill people
Member's all other embodiments obtained under the premise of creative work is not made, shall fall within the protection scope of the present invention.
Embodiment one
Fig. 1 shows a kind of flow diagram for code tracking method that one embodiment of the invention provides, should referring to Fig. 1
Method includes the following steps：
110th, the data of pre-established plug-in unit acquisition, the mesh run in the production environment that the pre-established plug-in unit is attached to are obtained
In mark process；
It should be noted that into line code with tracking when, plug-in unit is attached to by production ring by JVM codes instrument first
On target process when border is run；Then, when business is opened to the outside world, parameter and return value are captured, and then is performance hot spot point
Analysis provides the support in data.
120th, performance analysis of central issue is carried out, and determine target interface according to analysis result to the data got；
It should be noted that based on the data obtained in step 110, sieved by pre-set criteria and determine target interface；
Wherein, the efficiency of transmission of parameter and return value comparison interface layer that pre-set criteria can capture according to, and according to
Comparing result selects target interface from interface layer.Such as：If wherein the efficiency of transmission of some interface is far below other interfaces
Efficiency of transmission either some interface efficiency of transmission less than preset threshold value, then select the interface, and the interface is made
For target interface.
130th, in a production environment, slicing treatment is carried out to the target interface, extracts the corresponding program of performance hot spot
Segment；
It should be noted that slicing treatment is isolates target program piece from a code path in a production environment
Section；
140th, under the test environment, described program segment acquisition approach tracking information in operating status is tracked.
It should be noted that by using the mode of slice by the interface selected and Network Isolation, and will isolate
The corresponding usability of program fragments of performance hot spot independent operating in test environment, under isolation environment, acquisition approach tracking information；Separately
Outside, it should be noted that in order to obtain different data, can otherwise be realized by configuration log grade, such as：Configuration
Daily record is relatively low, only realizes print log；During configuration log highest, it is debugging level, the nearly all information of interface can be obtained, and then
Path trace message can therefrom be extracted.
As it can be seen that the present embodiment keeps apart from the code that magnanimity is run performance hot spot by using the mode of slice, and
Isolated operation under the test environment with prior art ratio, without carrying out any code transformation to existing application, has tracking essence
The advantages of degree is high, flexibility is strong.
Embodiment two
Fig. 2 shows a kind of principle schematics for code tracking method that one embodiment of the invention provides, should referring to Fig. 2
The principle of method is as follows：
210th, plug-in unit is attached in process when production environment is run by JVM codes instrument, captures parameter and return
Value to provide data support to search target decanting point, improves the search efficiency of target decanting point；
220th, parameter and return value based on plug-in unit capture, search and obtain target decanting point；JVM codes instrument will be predefined
Sensor is injected into target decanting point, and transaction middleware interface parameters value is captured by sensor；
230th, code slice program assembles according to the transaction middleware interface parameters value, generates test case；
240-250, business detection processing is carried out to production isolation middleware and test middleware according to the test case,
The business detection is from existing network service stream, data flow extraction procedure segment.With higher business similarity and matching degree, because
This probability that largely Upgrade Problem reappears.
260th, because being isolated entirely from production, the daily record rank that can start DEBUG patterns carries out production isolation middleware
Path trace；
It should be noted that DEBUG patterns correspond to maximum daily record rank, in such a mode, daily record will record debugging letter
Breath etc..
270th, code path the matching analysis is carried out based on the middleware code routing information in daily record, obtains code path；
Alternatively, starting session tracking performs step 280；
280th, the session of database is sent to from specific machine can also start session tracking on the database, to be based on SQL
(Structured Query Language) routing information carries out code path the matching analysis, obtains code path.
As it can be seen that performance hot spot is narrowed down to interface layer, then producing by the function slice of interface layer by the present embodiment first
Shielding system re-calls, and fine function operation track is obtained by starting max log rank.It avoids to native applications
Transformation, while positioning problems granularity can narrow down to specific code row.
Embodiment three
Web front end system, which is crossed, calls some package interfaces to call transaction middle layer indirectly, is divided into two kinds of technologies here and realizes
Mode：Firstth, JVM directly invokes production isolation middleware CICS/ test transaction middlewares Tuxedo by transaction gateway；The
2nd, CICS/Tuxedo is called by enterprise's bus indirectly.Wherein, first method includes three steps.
Referring to Fig. 3, the first step specifically includes：
310th, storehouse analysis is carried out to the allocating stack that code instrument suite obtains；
320th, on entire allocating stack, the performance hot spot of least significant end is chosen；
It should be noted that more the business realizing of bottom often has wider implantation capability, can cover most of
Business scenario.If prompting, which is ongoing thread, waits for Object.wait (), either synchronously or asynchronously adjusted in waiting in fact
Return has little significance to path trace, it is therefore desirable to be called by the interface of fine CPU sample acquisitions more bottom detailed
Feelings, CPU samplings carry out entire thread stacks at interval of a smaller period (about 10ms) full dose scanning, can look for
Go out information extremely basic in some JVM operational process.After CPU is sampled, it can be found that encapsulated before finally calling CTG again
Multilayer service logic, the purpose of the encapsulation are that by fixed format organization and interface call parameters are built message.
330th, the corresponding function of performance hot spot of selection is analyzed, and is according to the function that analysis result judges to choose
It is no that there is service attribute, if so, performing step 340；
340th, discriminant function parameter whether can normal sequence and unserializing, if so, perform step 350；
350th, whether discriminant function parameter is less than preset byte length threshold, if so, performing step 360；
360th, the corresponding decanting point of function target decanting point the most is chosen.
If judging to know, the function of selection can not normal sequence and antitone sequence without service attribute or function parameter
Change or function parameter is greater than or equal to preset byte length threshold, then judge that there is no be efficiently injected into a little in the function chosen；
Build the derived class for the corresponding function parameter of performance hot spot chosen；Clone's processing is carried out to the derived class, it is secondary to obtain clone
This；According to derived class sequencing method is preloaded, serializing processing acquisition is carried out to clone's copy and is efficiently injected into a little.
It should be noted that the function being initially injected a little will have crucial interface message, if believed without the corresponding interface
Breath, needs to find from decanting point context；Its subparameter can be with normal sequence and unserializing, it is ensured that energy after parameter reconstruct
Code slice program normally is passed to, while is necessary to ensure that serializing operation will not cause the change of object properties；Finally, it injects
The parameter volume of point cannot be excessive, and performance pressures are caused to runtime environment to avoid when exporting.Therefore based on this principle into
Row decanting point selects.
In addition, if third party's component object lacks sequencing method, need to be transformed program, be not suitable for producing
The investigation of emergency under environment, it is therefore desirable to further search downwards to other more reliable decanting points.Generally by ECI side
When formula (External CICS Call) calls CICS, it is related to the concept in the comunication area, i.e., as one for going out ginseng and entering that ginseng exchanges
A platform, front end applications are sent to comunication area COMMAREA by the way that sequence of message is turned to bytecode, are further connected to pair
The interface routine answered, therefore this decanting point can select contiguous function (link), parameter has (program ID, sequence of message
Bytecode, bytecode total length), word string form is converted to by bytecode and is transmitted to slice program.Since comunication area overall length is solid
Definite value 31744 if all 124K bytes can be reached by being converted to word string, generates production environment higher I/O, while general report
Text will not take the entire comunication area, according to statistics if non-batch service, message using space also just in 10%-20% or so, because
This can intercept about 30% or so bytecode, remainder polishing in code slice program.
As it can be seen that the present embodiment is by judging sensor injection phase, it is ensured that sensor injection safety, can
By property, the influence to operation system is smaller.
Example IV
Fig. 4 b, which are shown in a kind of code tracking method that another embodiment of the present invention provides, calls the flow of middleware to show
It is intended to, referring to Fig. 4 b, its basic ideas of second step are：Code slice is completely isolated from code path during production run for one
Usability of program fragments out can independently be run, in production environment referring to Fig. 4 a；
It specifically includes as follows：
410th, CTG environmental preparations：Since code slice extracts in front end Web layers of application, code slice
It needs to call a CTG environment as production, therefore produce isolation environment a CTG environment can be configured, by Web application journeys
Sequence far call；
420th, receive the test instruction sent from production, will enter to join comunication area bytecode character string and reversely rebuild bytecode
Sequence；
If the 430th, bytecode curtailment 31744, remainder bytes code is with 0 polishing；
440th, start ECI to call, CICS service names, user account permission including setting connection, start one it is new
Affairs, program connection and submission；
450th, record path tracking information；
It should be noted that code slice relative business is unrelated, it can be by entire any one ring of business operation flow
Section individually extracts operation.Isolation environment is without other calling services, therefore CICS serve logs can be adjusted to DEBUG grades
Not, with the output of realization detailed code path to transaction middleware.
460th, affairs is waited for return.
As it can be seen that code slice for one from code path during production run it is completely isolated out usability of program fragments, can be only
It is vertical to run in production environment, there are many advantages compared to other message analogy methods：The interference of other non-performance hot spots is such as abandoned
Factor only retains the problem of crucial, and close to production environment, reproducible ratio is higher.Traditional message analog form, one is
By front desk service operation simulation, the invalid data amount of generation is very big；Another kind is to be advised by the parameter that transaction middleware calls
Lattice, the message of simulation generation enterprise bus call, but many operators will not be by some interior business for information security consideration
Logic is exposed in enterprise's bus, because this latter can enforcement difficulty it is larger.
The third step of first method specifically includes：Class business is changed, may can not be reappeared, and have potential disturb in production
The influence of random business datum, therefore can preferentially select to simulate in test environment, re-send to production environment if can not reappear.
If inquiry class business can be simulated in production repeatedly.Call the part of Oracle can be backward for transaction middleware
The upper session initiation session trackings to carrying out self-isolation detection CICS environment of Oracle, specific practice are：Establishment one is system-level to touch
Device is sent out, the session for any connection to Schema starts 10046 events, finally exports SQL and performs detail time sequence, treats
After session status switches to INACTIVE states, 10046 events are closed.
Embodiment five
Fig. 5 a and the stream Figure 5b shows that calling middleware in a kind of code tracking method of one embodiment of the invention offer
Journey schematic diagram, referring to Fig. 5 a and Fig. 5 b, the basic thought of second method is：If judgement, which is known to be not present in the function of selection, to be had
Decanting point is imitated, then builds the derived class of the corresponding function parameter of performance hot spot of selection；Clone's processing is carried out to the derived class,
Obtain clone's copy；According to derived class sequencing method is preloaded, serializing processing acquisition is carried out to clone's copy and is efficiently injected into
Point.It is specific as follows：
This situation needs to place decanting point in the inlet of web front end application call enterprise bus, it will usually under encountering
Row problem：
1st, serialization process causes irreversible influence under production environment it is possible that the change of object properties can be caused,
Therefore it needs to confirm to third party's component manufacturer before use.To cope with this problem, this motion proposes two kinds of thinkings：It 1) can be in the note
Context procedures decanting point is found in access point upstream, generally builds the relevant operation that this parameter object is carried out and is captured,
Similar multiple Object.setAttribute ("<ATTR1>”,“<ATTR_VALUE>") assembling form；2) it is being injected
Before point parameter object serializing, an object copies are cloned, and argument sequence is carried out to this copy, it is timely after the completion of serializing
This copy is destroyed, this requires the object that can clone, therefore derives from clone's class：class ArgumentClonable
Extends Argument implements Clonable { }, and pass through cglib and remove dynamic definition Redefine, referring to figure
5a。
2nd, test case is usually unable to the true web front end system of full simulation one, therefore is added by injection point methods
The other configurations of load need to determine in advance, character encoding format such as message, whether using secure connection and encryption key, referring to
Fig. 5 b.
As it can be seen that the present embodiment is without in the case of being efficiently injected into a little, by being derived to existing parameter class and increasing serializing
Parameter object is cloned and is interfered to avoid to runtime environment by method.
