The present invention is in order to solve the drawback that conventional solution exists, further set forth the detection restorative procedure of a kind of network management system engineering failure of the present invention by following specific embodiment, below embodiment is described in detail, but not as a limitation of the invention.
The fault location of wavelength-division network management system in engineering and solve to have some problems, for example the phenomenon that the historical performance of the one-tenth section of network element is lost has appearred in network management system.In order to confirm that problem has appearred in the message whether network management system receives, and uses method of the present invention to carry out fault detect and reparation.
Detection of the present invention and restorative procedure are to detect or repair for what finish the work, can change as required: if fault the unknown can be finished failure location by detection; If, can directly revise with this method by the position of other approach known fault; But no matter be to detect or repair, its core thinking all realizes by interim loading of external module.This also is an inventive point of the present invention.
As shown in Figure 1, the present invention has increased one or more external modules (21 in former network management system 11 outsides, 22, ..., 2n), assist the fault detect and the solution of network management system by interim loading external module, wherein, external module can be a dynamic link library, also can be the plug-in unit (as some feature card or the like) of other modes.
As shown in Figure 2, the method flow diagram for the embodiment of the invention may further comprise the steps:
Step 200, at the some external modules of former network management system outer setting, each external module correspondence is finished the function of finishing the one or more working cell in the former network management system and is had fault detect and repair function;
For some fault of failing to confirm, need to detect fault earlier, have the external module of fault detection capability, the step after finishing by loading; For some fault of having confirmed, then directly repair, by the external module that loading has the fault restoration function, the step after finishing;
Step 201, according to fault to be detected or to be repaired, select corresponding external module (in fault detect external module and fault restoration external module, the function of just finishing corresponding function is inequality), customize and be kept in the external module tabulation with fault detect or fault restoration function;
Described tabulation is stored in the configuration file and (for other different situations, also can be kept in the database table);
Realization for described tabulation, can adopt multiple mode, such as: directly represent in the similar present embodiment by the file name of a series of external modules, or represent all external modules of matching, or represent all external modules under this catalogue or the path or the like by catalogue or pathname by include file name asterisk wildcard;
Step 202, network management system read the external module tabulation that has customized and preserved when restarting, load the external module in the tabulation successively, replace the working cell of the correspondence in the former network management system when external module is loaded automatically, finish corresponding function;
Network management system reads the title of each external module in the configuration file when starting, and loads all external modules in the tabulation;
Step 203, for fault to be detected, the relevant work unit of the abnormality detection network management system by monitoring external module work is finished failure location; For fault to be repaired, the external module with correction network management system function that passes through to be loaded is directly repaired fault.
For in the step 203, for fault to be detected, the relevant work unit of the abnormality detection network management system by monitoring described external module work is finished after the failure location, if be the fault of network management system, then externally unload the external module that current detection is used in the module list, and, this fault is repaired by revising the external module that external module tabulation loading has correction network management system function.
As shown in Figure 3, realize the method flow diagram that detects for adopting dynamic link library in the embodiment of the invention, in the present embodiment, adopt dynamic link library, specific implementation as external module, because the message that the conjecture network management system receives has problem and causes performance to be lost, whether the message that needs the location webmaster to receive exists fault, so can write a message receiver function PP with journal function, and put into dynamic link libraries AA, by loading this dynamic link libraries AA, be used for replacing the reception message function OO of former webmaster, can determine by checking daily record whether the message that receives really has problem, finishes fault detect, may further comprise the steps:
Step 300, at dynamic link library AA of former network management system outer setting, dynamic link library AA correspondence is finished the message input in the former network management system;
Dynamic link library AA has record Debugging message and journal function and fault detection capability, thereby can auxiliary detection is that fault has appearred in reception message function OO in the network management system, or the input of webmaster has problem to cause the message mistake;
Step 301 customizes dynamic link library AA and be kept in the tabulation of dynamic link library, and this tabulation is kept in the configuration file;
Increase the window of the tabulation of customization dynamic link library in the network management system interface, as shown in Figure 4, wherein 33 is tabulations of the file name of dynamic link library, and can be by record of button 44 increases with by record of button 55 deletions; The tabulation of the file name of dynamic link library is stored in the configuration file behind the close;
Step 302, network management system reads the title of the dynamic link library in the dynamic link library tabulation that has customized and preserved when restarting, and the dynamic link library AA in the loading tabulation, when being loaded, replaces dynamic link library AA the working cell of the correspondence in the former network management system automatically, be the reception message function OO of former webmaster, finish corresponding function;
Loading dynamic link library mainly is to realize that by the loading function of dynamic link library such as under windows platform, function name is LoadLibrary;
In this step, if in running, add or the unloading dynamic link library, tabulate and finish by revising the dynamic link library loaded, the user can open window as shown in Figure 4, increase a record AA by button 44, network management system need load the dynamic link library among the record AA simultaneously; Or by a record of button 55 deletions BB, network management system need unload the dynamic link library among the record BB simultaneously, closes window after modification finishes, and amended tabulation is saved in the configuration literary composition;
Step 303, by checking the message of dynamic link library AA record, whether correct, finish failure location if detecting the received message of the reception message function OO of former network management system;
Write a message receiver function PP with journal function, and put among the dynamic link library AA, the address of function PP is CC; Network management system is searched original message receiver function OO after loading dynamic link library AA, and the address D D of record function OO, the function address of rewriting the message reception of network management system then is CC, like this, when later network management system was called the message receiver function at every turn, the actual function that calls was function PP.PP has log recording function because of function, so can supply that all message accountings check the raw address that finds fault to send in file;
It is incorrect to be checked through message itself herein, can confirm that then fault is that the input of webmaster is wrong, but the input that can only determine webmaster here is wrong, and emphasis solves the problem of webmaster input, sees whether go back loss performance again after whether network management system itself has problem need wait input correct.
If check and find, the webmaster input is correct, but exists performance to lose, that can determine that then webmaster itself has fault, and can't determine to receive message function OO has fault, needs further to analyze, if be the problem of OO really, just can revise OO, then can carry out next step:
Step 304, the dynamic link library AA that the unloading current detection is used in the dynamic link library tabulation, and be added with the dynamic link library of revising the network management system function, and load this dynamic link library fault is repaired, thus the auxiliary network management system fault that solves;
Behind the network management system unloading dynamic link library AA, it stops to continue to move finishing its corresponding function, simultaneously DD is changeed back in the address of the message receiver function OO of network management system, to recover former message receiver function OO operation, finishes its original function;
The address CC of top receiver function PP can directly use the pointer of function PP to obtain, and the address D D of former receiver function OO can find by function name in the function address table of network management system;
The unloading dynamic link library mainly is to realize that by the unloading function of dynamic link library such as under windows platform, function name is FreeLibrary.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
