Fig. 1 is the schematic flow sheet for the variable read-write method based on shared drive that one embodiment of the invention provides.The party
Method includes：
101st, the configuration information and checking information of variable are read from shared drive.
102nd, judge whether the configuration information is correct according to the checking information.
If the 103, incorrect, read requests are sent to agent unit, and after agent unit response, again from institute
The configuration information that the variable is read in shared drive and checking information are stated until reading correct configuration information.
In above-mentioned steps 101, the configuration information of variable includes：Variable name and variate-value.The configuration information of variable is stored in
In shared drive, so, multiple processes in equipment can get change corresponding to the variable by variable from shared drive
Value.The configuration information of variable can be Key-Value forms, and what what Key was represented be that variable, Value represent is variable assignments.
Such as：I- databases IP address, the numerical value of j- first, process is during operation, database IP can be got by variable i
Location, and then database corresponding to access；It can get the first numerical value by variable j, and then after being carried out according to first numerical value
Continuous processing.
When the configuration information of variable is stored in shared drive, the corresponding storage one of configuration information of each variable can be directed to
Individual check code and/or version information；Wherein, check code generates for the configuration information according to variable and according to ad hoc rules, and
Updated with the renewal of the configuration information of variable.Version information is used for which time renewal of the configuration information of marking variable, and
Updated with the renewal of the configuration information of variable.Preferably, fixed length hash tables can be used to be managed shared drive, it is fixed
Each single item corresponds to a variable in long hash tables, and include the variable configuration information and its corresponding check code and/or
Version information.
, can be from altogether if the corresponding storage of the configuration information that each variable is directed in shared drive is a check code
The configuration information and check code that variable is read in internal memory are enjoyed, the checking information is the check code；If in shared drive
For each variable configuration information it is corresponding store is version information, then variable can be first read from the shared drive
Version information corresponding to configuration information (is stated, referred to as first version information) for convenience, then reads the configuration information of variable, is read
Version information corresponding to configuration information (being referred to as second edition information), the checking are again read off after taking the configuration information of variable
Information includes first version information and second edition information.
In above-mentioned steps 102, if checking information is check code, according to the configuration information read and according to described specific
Rule generation one refers to check code.Because the check code in shared drive is according to configuration information and according to same ad hoc rules
Generation, therefore, should be consistent with the check code read with reference to check code if configuration information and check code are read correctly.
If that is, consistent with the check code for reading to obtain from shared drive with reference to check code, illustrate to read matches somebody with somebody confidence
Breath is correct；If inconsistent with the check code that is read from shared drive with reference to check code, illustrate the configuration read
Information and/or check code are wrong, are configuration information read error or verification due to that can not determine bottom in this case
Code read error, therefore, the configuration information that can uniformly think to read are wrong.
If checking information is first version information and second edition information, compare first version information and second edition letter
Whether breath is consistent.If in reading process, configuration information is not updated by other processes, and its version information will not also update, therefore
The version information of front and rear reading should be consistent；If in reading process, configuration information is updated by other processes, and its version information also can
This renewal, therefore, the version information of front and rear reading are inconsistent.That is, if both are consistent, illustrate to read correctly；If no
Unanimously, then read error is illustrated.
In a kind of achievable scheme, when the configuration information of variable is stored in shared drive, in matching somebody with somebody for each variable
Increase CRC CRC (Cyclic Redundancy Check) after confidence breath.The CRC check code is according to change
The configuration information of amount and according to ad hoc rules (i.e. coding rule) determine.
The general principle of CRC is：Spelled again after K positions information code (namely configuration information of above-mentioned variable)
The check code of R positions is connect, whole code length is N positions, and therefore, this coding is also (N, K) code.For one given (N, K)
Code, it can prove the multinomial G (x) that a highest power is N-K=R be present.The verification of K positions information can be generated according to G (x)
Code, and G (x) is called the generator polynomial of this CRC code.The specific generating process (namely above-mentioned coding rule) of check code is：
Assuming that configuration information is represented with message polynomial C (X), C (x) is moved to left into R positions, then can be expressed as C (x) × xR, such C (x)
The right will vacate R positions, and here it is the position of check code.Pass through C (x) × xRDivided by the remainder that generator polynomial G (x) is obtained is just
It is check code.
After the configuration information of variable and CRC check code are read from shared drive, the configuration information of variable can be passed through
Whether the configuration information that can judge to read of testing of the coding rule between CRC check code is correct.
Specifically：The checking information is first circulation redundancy check code；And according to judging the checking information
Whether configuration information is correct, including：According to the configuration information read, second circulation redundancy check code is determined；Compare institute
State first circulation redundancy check code and the second circulation redundancy check code；If the first circulation redundancy check code and described the
Two CRCs are identical, then it is correct configuration information to judge the configuration information.
If to the configuration information that reads using the second circulation redundancy check code obtained after the processing of above-mentioned coding rule with
First circulation redundancy check code is consistent, then it is correct for can determine that the configuration information read；It is if inconsistent, it is determined that to read
Configuration information to be wrong.
It should be noted that CRC check code corresponding to the configuration information of variable is after configuration information update in shared drive
It can automatically update.
It is each variable when the configuration information of variable is stored in shared drive in another achievable scheme
Configuration information increases by a version information, and version information updates with the renewal of configuration information.Such as：The configuration information of variable is every
Once, corresponding version information adds 1 for renewal.Now, the configuration information of variable and the step of checking information are read from shared drive
Suddenly include：After first version information corresponding to the variable is read, configuration information corresponding to the variable is read；Reading
After configuration information corresponding to the variable, second edition information corresponding to the variable is again read off；The checking information includes
The first version information and the second edition information.In other words, when variable is read from shared drive, version is first read
Information, then configuration information is read, finally again read off version information.If the version information that front and rear twi-read arrives is consistent, say
It is bright during this reads the configuration information of the variable, the configuration information of the variable is not updated.
In above-mentioned steps 103, an agent unit is set in equipment that can be by operationally stating process.The agent unit root
According to the transmission time order and function ordinal response of reading/renewal request of each process.Predeterminable setting：If process will be in shared drive
The configuration information of variable when being updated, then need to send renewal request to agent unit；If process will be from shared drive
When reading the configuration information of variable, without sending read requests to agent unit, only in read error, just need to agency
Unit sends read requests.
When process read error, to the agent unit send read requests, and the agent unit response after, again from
The configuration information and checking information of variable are read in shared drive, that is, repeat the above steps 101 and step 102 until read just
True configuration information.Generally, process read error, other processes has been primarily due to and have been updated, if the renewal of other processes is completed
Before, just go ceaselessly to re-read, the configuration information read remains mistake, and also wastes process resource.At this
In invention, when agent unit has responded read requests, illustrate that the renewal operation of other processes has been completed, at this moment, can be very big
The configuration information for ensuring to re-read in degree is correct.
The transmission time order and function ordinal response that agent unit is asked according to reading/renewal of each process, such as lower section can be used
Formula is realized：, please by the read requests or the renewal after the agent unit receives the read requests or renewal request
Ask and be input in message queue, and according to read requests described in ordinal response or the renewal request of joining the team.Wherein, message queue
It is the container that message is preserved in the transmitting procedure of message, because message queue is First Input First Output, therefore, it can be ensured that message
It is the sequential processes sent according to them.
It should be noted that the process for reading or updating request is sent to agent unit after the completion of reading or renewal, can
One is sent to agent unit performing and complete signal, agent unit responds follow-up read or more after receiving and performing and complete signal
New request.
In technical scheme provided in an embodiment of the present invention, it can determine whether out reading according to the checking information of the variable read
Whether the variable is updated by other processes during taking, and explanation reads correct if not being updated；If being updated, illustrate to read
Take incorrect, then send read requests to agent unit, the configuration information and checking information of the variable are re-read with request
Until reading correct configuration information.It can be seen that the present invention can improve process from the reading accuracy in shared drive.
In above-described embodiment and following each embodiments, the above method also includes：Receive the described of far-end server transmission
The update notification of variable；Renewal request is sent to the agent unit according to the update notification；Responded in the agent unit
Afterwards, the configuration information of variable described in the shared drive is updated.
In the present embodiment, the relevant variable that the configuration information of variable only stores on far-end server in shared drive
Configuration information can just be updated when updating.Far-end server can be after the configuration information update of the variable of its storage to upper
State the update notification that equipment sends the variable.After equipment receives update notification, a renewal process can be started, to be entered by renewal
Journey sends renewal request according to the update notification to the agent unit.And after agent unit response, then go renewal shared
The configuration information of variable described in internal memory.
In addition, the checking information that the variable after the configuration information of variable, is updated described in the shared drive is updated,
It is renewal check code and/or version information.If checking message is check code, according to the configuration information after renewal and according to institute
State ad hoc rules and generate new check code；If verifying, message is first version information and second edition information, in the variable
