Description
Technical field
The application relates to communication field, particularly relates to a kind of data processing method and data processing equipment.
Background technology
Distributed data processing also can be called Distributed Calculation, distributed treatment or distributing real time system.Distributed data processing refers to when calculating or process, promoter is by calculative data or need affairs to be processed to be divided into multiple son calculating, son process or subtransaction, then this little calculating, son process or subtransaction are distributed to multiple participant to carry out calculating or processing, last promoter integrates the result of each participant and obtains final result.
In prior art, distributed transaction is divided into multiple subtransaction by promoter, and distributes to multiple participant, inquires about each participant respectively and whether can process the subtransaction be assigned with.The situation that participant uses according to own resource responds promoter.If this participant can process the subtransaction be assigned with, then give this subtransaction Resources allocation, comprise the space of allocation process, the time etc. of process, and reply promoter " ready "; If this participant cannot process the subtransaction be assigned with, then reply promoter " not ready ".
Promoter, after all participants of confirmation can process the subtransaction be assigned with, orders all participants to process the subtransaction be assigned with; Participant processes the subtransaction be assigned with separately, and after process terminates, result is sent to promoter.
If there is any one participant cannot process the subtransaction be assigned with, promoter terminates this distributing real time system, and orders all participant's rollbacks, namely orders all participants to discharge the resource of distributing to the subtransaction of this distributed transaction.
If promoter inquires about after whether certain distributed transaction participant can process the subtransaction be assigned with, the communicating interrupt between promoter and this participant, this participant to subtransaction Resources allocation, and replys promoter " ready " according to the inquiry of promoter.Due to communicating interrupt, promoter does not receive the response of this participant " ready " in the given time, thinks that this participant cannot process the subtransaction be assigned with, then terminates this distributing real time system, orders all participant's rollbacks.Due to the communicating interrupt between this participant and promoter, this participant does not receive the order of rollback, retains the resource reserved to this subtransaction, and namely this participant has carried out once empty rollback, and the subtransaction that this participant is assigned with is called the subtransaction of suspension.
The another kind of situation hanging subtransaction that produces is, this participant is according to consuming time longer to subtransaction Resources allocation of the inquiry of promoter, promoter does not receive the response of this participant " ready " in the given time, think that this participant cannot process the subtransaction be assigned with, then order all participant's rollbacks.Because this participant is still to the subtransaction Resources allocation be assigned with, even if receive the order of rollback, also cannot discharge the resource reserved to this subtransaction, namely this participant has carried out once empty rollback, and the subtransaction that this participant is assigned with is called the subtransaction of suspension equally.
In above-mentioned two situations, promoter have issued the order of rollback, gives tacit consent to all participants and has all carried out rollback, can continue to distribute subtransaction, and what promoter cannot learn that this participant carries out is once empty rollback.Subsequently, promoter initiates the process of same distributed transaction, and distribute subtransaction to the above-mentioned participant with suspension subtransaction, this participant also still can give same subtransaction Resources allocation, and reply promoter " ready ".So, above-mentioned participant is assigned with twice resource to same subtransaction.Processing stage, this participant may carry out twice process to same subtransaction, and submits the result of carrying out after twice process to; Or the result of the subtransaction of above-mentioned suspension formerly may be submitted to promoter by this participant.
Visible, in prior art, when processing distributed transaction, if there is the subtransaction hung, then the mistake that subtransaction may occur is submitted to, reduces the reliability of distributing real time system.
