Embodiment
Below in conjunction with drawings and the specific embodiments to the detailed description of the invention.
For clearly describing specific embodiments of the invention, below to verify as the system master unit of first side and to be that example is illustrated as the consistency of configuration data between the veneer of second side, institute is understood that, specific embodiments of the invention are not limited to verify the consistency of configuration data, and are suitable equally for needing to verify conforming any data between second side and first side.
In software running process,, need may have access to configuration data in veneer this locality for satisfying the access performance demand.Owing to involving reasons such as data volume, veneer quantity, it is feasible hardly that the configuration data between the veneer compares mutually, normally compares respectively with the configuration data of the configuration data in the system master unit as benchmark and each veneer.
Behind the system master unit power-up initializing first time, the set of the minimal configuration data that the system of foundation can normally move, this is integrated into the primary data that the system master cell side forms system configuration data.After system configuration data changes at every turn, all form corresponding data snapshot.As shown in Figure 3, Fig. 3 is a system configuration data snapshot schematic diagram, forms system configuration data snapshot 0 constantly at t0, forms system configuration data snapshot 1 constantly at t1 ... form system configuration data snapshot n constantly at tn.The content of these data snapshot forms data file and storage.
Because the variation of follow-up system configuration data can only be undertaken by configuration order, data snapshot after each configuration order runs succeeded is different with the last data snapshot, in other words, data snapshot is by primary data, a series of configuration order and set up, therefore, at least the Transaction Identifier (affairs ID) that comprises transaction number at the data configuration operation setting of configuration order correspondence, wherein, transaction number is to be primary data, every one number that configuration order is provided with, and can adopt and hold continuous incremental manner distribution.Transaction Identifier also can be used as sign and the binding of corresponding data file and the preservation of data snapshot except preserving in internal memory.Preferably, Transaction Identifier also can further comprise timestamp, in order to the rise time of designation data snapshot, to increase the uniqueness of Transaction Identifier, the appearance Transaction Identifier conflict on the veneer that is controlled by the other system main control unit that avoid being inserted into the native system main control unit and former.Timestamp is generated when the order of veneer down distributing configuration data in the system master unit usually, and with Transaction Identifier, configuration data one in the same way veneer issue.
Why this notion of Transaction Identifier is proposed, be because the data between system master unit and the veneer inconsistent be to fail to cause synchronously by data configuration.Therefore, whether realized data configuration operation (that is: data configuration has consistency) synchronously, just can determine the data consistency between system master unit and the veneer apace as long as can know system master unit and veneer.On the other hand, no matter be that system master unit or veneer can be considered as new affairs with each data configuration operation; Therefore, only need be each data configuration operated allocated Transaction Identifier, and the consistency of the Transaction Identifier of the Transaction Identifier of comparison system affairs that main control unit is realized and affairs that veneer is realized, just can determine the consistency of data configuration operation between system master unit and the veneer, and then finally determine the data consistency between system master unit and the veneer.As seen, just can directly draw the consistency of data by the consistency of Transaction Identifier.
Referring to shown in Figure 4, Fig. 4 is the schematic diagram of concrete transaction information in the embodiment of the invention.The system master unit links to each other with veneers such as veneer 1... veneer n respectively.In actual applications, the operating system that is adopted for the system master unit without limits, as: the system master unit is based on (SuSE) Linux OS, veneer is based on operating systems such as Linux, vxworks, for whether adopting database to preserve data also without limits, as: system master unit and veneer all adopt the main memory DBM data.
Preserve the veneer transaction information of each veneer in the system master unit, described veneer transaction information comprises veneer address, executed Transaction Identifier and response transactions sign, wherein, the described veneer address configuration data that obtains corresponding veneer for the system master unit; Described executed Transaction Identifier is in system master unit successful execution configuration order, promptly, after configuration data forever has been stored in the system master unit, generates and preserve when carrying out the data configuration operation, and be issued to veneer with configuration data at system master cell command veneer; Described response transactions sign system master unit receives that the Transaction Identifier that responds from veneer preserves.
Above-mentioned veneer transaction information can be kept in the transaction number file, storage format as shown in Figure 5, Fig. 5 shows the form of system master unit store transaction sign.As seen from Figure 5, the latest transaction sign that the system master unit stores the veneer number and distributed, wherein, the latest transaction sign stores all Transaction Identifiers that distribute in the systematic master control board, the overall situation that the expression Transaction Identifier distributes; Also store the transaction information of each veneer in order, comprise the address, executed Transaction Identifier of veneer, response transactions sign.
In the veneer side, when veneer is used the configuration data receive and is carried out the configuration of self, the up-to-date described executed Transaction Identifier of receiving is preserved as this veneer executed Transaction Identifier, simultaneously this Transaction Identifier is returned to the system master unit in the mode that responds.The executed Transaction Identifier of this preservation is preserved in the veneer data file that veneer self is preserved as the transaction information of veneer.
Referring to Fig. 6, Fig. 6 is that the configuration data of online data layoutprocedure in one embodiment of the invention is verified flow chart, and this flow process may further comprise the steps:
Step 501: the system master unit receives the data configuration order at veneer, generally includes the configuration data at this veneer in this order.
Step 502: the system master unit be the data configuration order of receiving at this data configuration operated allocated first Transaction Identifier, and carry out described data configuration order at the veneer data of self safeguarding.
Step 503: the system master unit upgrades the first executed Transaction Identifier of preserving from as described veneer with described first Transaction Identifier that distributes, and the first executed Transaction Identifier after will upgrading writes in veneer data file and/or the transaction number file; Also upgrade the veneer data file of preserving from as this veneer.
Step 504: the first executed Transaction Identifier before the system master unit upgrades described veneer and described first Transaction Identifier of distribution are carried at the first executed Transaction Identifier, first Transaction Identifier and the configuration data that send in the data configuration message before the described renewal of described veneer together with the configuration data in the described data configuration order and normally are carried on and send to described veneer in the data configuration message.
Step 505: when veneer is received from the first executed Transaction Identifier before the described renewal of system master unit, first Transaction Identifier and configuration data, judge whether the current second executed Transaction Identifier of self preserving is consistent with the first executed Transaction Identifier before the described renewal of receiving.
Step 506: at described decision operation, if judged result is consistent, illustrate that the situation of communication loss did not take place configuration order, the last performed data configuration of veneer is consistent with the data configuration that system master cell command veneer is carried out, therefore veneer determines that the data of self and the data of system master unit have consistency, and then use the described configuration data of receiving and self carrying out the data configuration operation, veneer also upgrades self second executed Transaction Identifier of storage originally with first Transaction Identifier of receiving usually; Otherwise, illustrate that the data configuration that last performed data configuration of veneer and system master cell command veneer are carried out is inconsistent, therefore veneer determines that the data of self and the data of system master unit do not have consistency, and does not use the described configuration data of receiving and carry out data configuration at self.
Step 507: at different judged results, veneer sends the data configuration response that comprises different content to the system master unit.Particularly, when veneer and system master unit have data consistency, include the second executed Transaction Identifier after veneer upgrades in the described data configuration response; When veneer and system master unit do not have data consistency, include the failure sign in the described data configuration response.
Step 508: when receiving from the response of the data configuration of veneer, the system master unit determines according to the content that is comprised in this response whether self is consistent with the configuration data between the veneer, and sends prompting.
Particularly, during the second executed Transaction Identifier after comprising renewal in the response of described data configuration, the first executed Transaction Identifier after the renewal that the system master unit relatively self is preserved and this described second executed Transaction Identifier, when both are consistent, determine to have data consistency between self and the veneer, and with this second executed Transaction Identifier as up-to-date first the response transactions sign preserve, and can be further to send mode reminder-data configuration successful and data consistency such as audio frequency and video; When comprising the failure sign in the response of described data configuration, the system master unit determines do not have data consistency between self and the veneer, and to send mode reminder-data configuration failure such as audio frequency and video.
Step 509: if the overtime data configuration of not receiving responds, the system master unit can be by the first response transactions sign of the first executed Transaction Identifier that relatively upgrades and self storage, when both are consistent, judge the data consistent between veneer and the system master unit, otherwise, then output prompting.Therefore, use the executed Transaction Identifier and response transactions identify the communication link fails that can distinguish different directions.
The foregoing description has only been described the online method of verifying when carrying out data configuration; similarly; when detecting the normal or communication link of single board state in the system master unit and recovering, step 504 can also be such: the first executed Transaction Identifier before system master unit active system main control unit upgrades veneer and described first Transaction Identifier of distribution send to veneer.
Referring to Fig. 7, Fig. 7 is that the configuration data when single board starting or fault recovery is verified flow chart in another embodiment of the present invention, and this flow process may further comprise the steps:
Step 601: after startup or fault recovery, veneer is to system master unit requests loading monoboard data file.
Step 602: when the timer that veneer self is provided with overtime, but when not receiving the configuration data from the system master unit as yet, veneer is directly used the data configuration of the allocation data recovering self in the local veneer data file (memory carrier of veneer configuration data) of being preserved.Certainly, if veneer has in time been received the configuration data from the system master unit, veneer is then used the configuration data of receiving and is carried out the data configuration of self.
What step 601 to step 602 was described is the data configuration strategy of veneer when starting, and does not have strict time order and function order between follow-up each step.
Step 603 is to step 604: finish or during fault recovery in startup, the system master unit is to the veneer transmitting system master control event notice that goes into operation.
Step 605: receive when system master from the system master unit goes into operation event notice that veneer is carried on Transaction Identifier with the current second executed Transaction Identifier of self preserving and verifies in the request and send to the system master unit.
Step 606: the current first executed Transaction Identifier of the relatively local described veneer of preserving in system master unit and from the second executed Transaction Identifier of this veneer, when comparative result is executed Transaction Identifier unanimity, illustrate that veneer performed data configuration last time is consistent with the data configuration that system master cell command veneer is carried out, therefore the system master unit determines that the data of self and the data of veneer have consistency; When comparative result is that the executed Transaction Identifier is when inconsistent, illustrate that the data configuration that data configuration that veneer last time is performed and system master cell command veneer are carried out is inconsistent, therefore the system master unit determines that the data of self and the data of veneer do not have consistency.
Step 607: when comparative result is executed Transaction Identifier when inconsistent, the system master unit sends prompting, as: to send mode reminder-data inconsistencies such as audio frequency and video.Certainly, when comparative result is executed Transaction Identifier when consistent, the system master unit also can send prompting, as: to send mode reminder-data consistency such as audio frequency and video.
Because above-mentioned verification process is simple, therefore can supports cycle or command triggers and carry out data check.
As shown in Figure 8, data check starts, when system master unit application Fig. 6 or flow process shown in Figure 7 determine that the data of system master unit and veneer do not have consistency, optionally, can also obtain the details of inconsistent data, can be by calculating CRC check and the details of obtaining inconsistent data, and, utilize Reset Board, perhaps synchrodata mode etc. is carried out the data sync operation, and it is consistent with the system master unit that the veneer data are returned to; When application drawing 6 or flow process shown in Figure 7 determine that the data of system master unit and veneer have consistency, need not Reset Board or carry out the simultaneous operation of data file.
Because the checkout procedure of Transaction Identifier is very fast in the embodiment of the invention, and when the data of verifying out system master unit and veneer are inconsistent just by calculating CRC check and obtaining details about inconsistent data, promptly need not be when verifying out the data consistent of system master unit and veneer by calculating CRC check and the details of obtaining about inconsistent data, avoided in the prior art at every turn all the calculated data CRC check and, thereby the resource of having saved system CPU on the whole.
Above-mentioned by calculating CRC check and obtaining as shown in Figure 9 about the flow process of the details of inconsistent data.Referring to Fig. 9, Fig. 9 is the flow chart that obtains about the inconsistent data details, and this flow process may further comprise the steps:
Step 701: the system master unit receive from its outside and at the system master unit have inconsistent data veneer obtain the order of inconsistent data details.It is alternatively, described that to obtain the order of inconsistent data details also can be from inside, system master unit.
Step 702: the system master unit sends a request message to veneer.
Step 703: when receiving the request message from the system master unit, veneer calculate local data CRC check and.
Step 704: veneer will calculate the CRC check of gained and be carried on and send to the system master unit in the response.
Step 705: the CRC check of the algorithm computation local data that the system master unit application is identical with veneer and.
Step 706: the system master unit relatively from the CRC check of veneer and with the CRC check of self calculating gained and.
Step 707: the system master unit sends to veneer with the sign of CRC check and inconsistent object data, to obtain the details of inconsistent data.
Particularly, described CRC check and normally calculate, the sign of object data and verification and constitute one two tuple jointly at object data; The CRC check that is comprised in the described response and be two above-mentioned tuples list, system master unit be by with this two tuples list and self calculate the CRC check of gained and compare, and can draw the lacking of object data, situation unnecessary and inequality.
Step 708: veneer is according to the details of obtaining corresponding configuration data from the sign of the object data of system master unit, and the configuration data details of obtaining are sent to the system master unit.
Step 709: the inconsistent data details from veneer are preserved in the system master unit, for watching.
Step 710: the response of inconsistent data details is obtained in the output of system master unit, can also point out the details of inconsistency data to send modes such as audio frequency and video.
Further, also can utilize board resetting or synchrodata mode, it is consistent with the system master cell data that the veneer data are returned to.
One of ordinary skill in the art will appreciate that all or part of step that realizes in the foregoing description method is to instruct relevant hardware to finish by program, described program can be stored in the computer read/write memory medium, and this program is carried out above institute in steps.Described storage medium is ROM/RAM, magnetic disc, CD etc.
The embodiment of the invention not only provides the data check method, but also the data check device is provided.
Referring to shown in Figure 10, Figure 10 realizes the device schematic diagram that data consistency is verified for the system master unit.Wherein,
