S2012: in the database that first server is pre-established, creating sequence object based on the property parameters,
And the initial value is exported as the current sequence value of the sequence object.
According to the sequence creation instruction received, every property parameters in sequence creation instruction are parsed, in data
Creation and the matched sequence object of property parameters in library.
Preferably, property parameters further include memory options value.If memory options value is CACHE, sequence object is stored in
In memory, to improve the processing speed of sequential value and improve the formation efficiency of each sequential value in sequence object.
In the embodiment of the present invention, each sequential value as corresponding to sequence object will finally export jointly with random code is
An entity card number needed for operation system, therefore by the property parameters of user input sequence object, user can be supplied to more certainly
Definition space allows user according to the fabrication demand of operation system, the create-rule of customized a part of entity card number, because
This improves the allocation flexibility of entity card number to a certain extent.
S202: when receiving the sequential value call request of second server sending, the sequence pair created is obtained
As, and read the current sequence value of the sequence object.
In second server, one or more management systems are run, each management system is for managing and a type
The associated business datum of the business of type.
When any operation system needs to obtain new entity card number, will generate based on having been created in oracle database
The sequential value call request of sequence object, and the sequential value call request is sent to above-mentioned oracle database.Work as Oracle
When database receives the sequential value call request of second server sending, the operation to match with sequential value call request is run
Instruction, that is, according to sequence names entrained by sequential value call request, acquisition and the matched sequence object of the sequence names, and
Read the current sequence value of sequence object.The sequence names as entrained by different sequential value call requests with it is a type of
Business is corresponding, therefore different types of business will call different sequence objects, so that guaranteeing is not in weight under same class business
Multiple entity card number.
In the embodiment of the present invention, currval mode is arranged by puppet, obtains the current sequence value of sequence object.
S203: according to preset step-length and the current sequence value, generating next sequential value of the sequence object, and
The current sequence value for updating the sequence object is next sequential value.
According to preset step-length corresponding to sequence object and S202 current sequence value obtained, arranged by puppet
The mode of nextval, next sequential value of real-time formation sequence object, then the current sequence value of sequence object will replace with described
Next sequential value.
For example, when receiving the sequential value call request of second server sending, if what is read calls with sequential value
The current sequence value for requesting matched sequence object is a, and the growth step-length of sequence object is 2, then the next sequential value generated is a
+ 2, and inscribed when newest, the current sequence value of sequence object will be changed to a+2.
S204: it obtains card number length value entrained by the sequential value call request and obtains updated described current
The character length of sequential value.
S205: according to the difference of the card number length value and the character length of the current sequence value, character length is obtained
For each numerical value of the difference.
When receiving the sequential value call request of second server sending, which is parsed,
To obtain card number length value and sequence names entrained by sequential value call request.Wherein, card number length value indicates the second clothes
The character length of the entity card number obtained needed for business device；Sequence names indicate the sequence object called needed for second server
Title.
According to sequence names entrained by sequential value call request, enable under being generated with the matched sequence object of the sequence names
One sequential value, and after next sequential value is updated to current sequence value, identify the character length of current sequence value.The sequence of calculation
It is worth the difference of the character length of card number length value entrained by call request and current sequence value.
For example, current sequence value is 238246223, then the character length of current sequence value if card number length value is 11
It is 9, the difference of the character length of card number length value and current sequence value is 11-9=2.
Obtain digit all numerical value identical with above-mentioned difference.For example, in the examples described above, if card number length value and current
The difference of the character length of sequential value is 2, then the required numerical value obtained is the numerical value that digit is 2, i.e., all between 00 to 99
Numerical value.
S206: according to the pre-set selection probability of each numerical value institute, described selection probability highest one is obtained
Or multiple numerical value, and one of those described numerical value is determined as current time random code generated.
The numerical value of isotopic number is not pre-generated in first server.Wherein, the identical each numerical value of digit is pre-stored within
In one tables of data, and each numerical value is corresponding with a selection probability.The selection probability of each numerical value is for indicating identical in digit
All numerical value in, which can be selected the probability as a random code.In the initial state, each in same tables of data
The selection probability of a numerical value is identical, is 1/10x, x is the digit of numerical value.
For example, when generating 100 numerical value between 00 to 99, for each of these numerical value, in the initial state
Selection probability be 1/100.
From S205 each numerical value obtained, determine to choose the highest one or more numerical value of probability.By default
Random number Algorithms of Selecting, a numerical value is selected in each numerical value determined, is given birth to using the numerical value as current time
At random code.It is found that the character length of random code is the difference of the character length of card number length value and current sequence value.
S207: the random code and the updated current sequence value are spliced, and splicing result is back to
The second server, so that the second server exports the splicing result for entity card number.
First server before returning to entity card number, by the random code of generation be placed in sequence object current sequence value it
Before, and above-mentioned random code and current sequence value are spliced by preset stitching algorithm, thus one entity card number of output.Thus may be used
Know, the card number length of the entity card number of output is identical as card number length value entrained by sequential value call request.
The current sequence value of entity card number and sequence object that the embodiment of the present invention is suitable for generating needed for operation system
Under the case where character length has differences, for example, being counted if operation system needs to distribute the entity card number of 11 digit word lengths
According to sequence object in library current sequence value be 9, then card number length value entrained by sequential value call request and update after
Current sequence value character length difference be 2, therefore generate 2 bit values random code so that the random code of 2 bit values and 9
The current sequence value of bit digital can export the entity card number for one 11 needed for operation system after splicing, meet business
Actual demand.
In the embodiment of the present invention, operation system only need to issue sequential value calling to first server based on second server and ask
It asks, just the random code that the current sequence value for the sequence object that first server is created generates in real time with it can be spliced,
With output for a new entity card number.Since the current sequence value of sequence object is just updated after real-time generate, because without
It will appear the case where same entity card number is distributed in repetition, thus but also operation system acquires the current of sequence object every time
After sequential value, directly the splicing result of itself and a random code can be exported as entity card number, without judging the entity card number again
Whether probably already exist, to improve the formation efficiency of entity card number.Pass through card number entrained by parsing sequential value call request
Length value, can be according to the difference of card number length value and current sequence value, the random code of dynamic acquisition kinds of characters length；Pass through
Random code and current sequence value are spliced, the entity card number that first server is exported and operation system reality
Required card number length value matching, thus meets the actual demand of different business systems；Since the length of random code is different, and
Its numerical value has randomness, therefore it is enabled to splice with current sequence value, creates a further reduction the recurrence probability of entity card number.Separately
Outside, multiple operation systems can share the sequence object in the database of first server, thus realize across operation system and
Cross-server generates unique entity card number, and avoiding will appear asking for duplicate entity card number between more distributed servers
Topic.
As another embodiment of the present invention, as shown in figure 4, after above-mentioned S202, further includes:
S208: if the current sequence value of the sequence object is identical as the maximum-sequence-value, and the looping options value
Not recycle, then stop the next sequential value for generating the sequence object.
S209: it enables the database issue sequential value and exhausts prompt, and in the sequence for receiving the second server sending
When train value call request, return is refused to respond.
Maximum-sequence-value is the maximum value in each sequential value corresponding to user's sequence object predetermined.If step
The current sequence value read in S202 is identical as preset maximum-sequence-value, then reads the looping options value of sequence object,
To judge that the looping options value does not still recycle for circulation.
If looping options value is not recycle, database issues sequential value and exhausts prompt, to prompt database administrator to work as
Each sequential value corresponding to preceding created sequence object has been distributed to matched operation system, that is, prompt data
Without the other sequences value that can be used for distributing in library manager's current sequence object.Therefore, prompt is exhausted based on the sequential value, number
It can be confirmed whether to need to re-create and the matched another sequence object of the operation system according to library manager.If desired it re-creates
Another sequence object, then database administrator can re-enter the property parameters of new sequence object.Receiving sequence creation
Before instruction, if persistently receiving the sequential value call request of operation system sending, information will be refused to respond and be back to this
Second server where operation system.
Preferably, by default, the looping options value of sequence object is not recycle.
In the embodiment of the present invention, by reaching maximum-sequence-value in the current value of sequence object, and looping options value is not
When circulation, issues sequential value and exhaust prompt, enable database administrator to know the real-time distribution state of sequential value, build in time
New sequence object is found, to guarantee that each operation system can normally obtain the sequential value in database, improves entire entity
The operation stability of card number distribution system.Since looping options value is when not recycling, allocated each sequential value will not be followed
Ring obtains, therefore will not repeat same sequential value to be distributed to other operation systems, therefore, entity card provided in an embodiment of the present invention
Number generation method, which is realized, generates unique entity card number across operation system and cross-server, avoids more Distributed Services
The problem of will appear duplicate entity card number between device.
As an embodiment of the present invention, Fig. 5 shows the entity card number generation side of further embodiment of this invention offer
The implementation process of method, details are as follows:
S210: obtaining historical record data table, and the historical record data table generated is gone through for recording each moment
History random code.
S211: each history random code stored according to historical record data table determines current time institute generated
State the frequency of occurrence in the historical record data table of random code.
In the embodiment of the present invention, determined from pre-generated each numerical value for a numerical value as random code
Afterwards, which will be stored to historical record data table, become a history random code.
After a random code for selecting current time in S206, judge the random code whether with historical record data table
In any history random code it is identical.
If the random code is identical as any history random code in historical record data table, it is determined that identical as the random code
History random code number, that is, determine the frequency of occurrence in historical record data table of the random code.It is found that occurrence out
Number characterizes the number that the random code was once used.
S212: for each character bit of the random code, numerical value of the history random code on the character bit is determined
Cumulative frequency identical with numerical value of the random code on the character bit.
Random code generated for current time reads the numerical value on its each character bit.For example, if random code is
" 132 ", then the numerical value on a position, ten and hundred is respectively " 2 ", " 3 ", " 1 ".
For numerical value of the random code on each character bit, the numerical value is counted respectively in the same character bit of history random code
On the number that occurs.Cumulative frequency indicates the summation of the number corresponding to each character bit.Wherein, in statistics accumulation time
