Embodiment
With reference to Figure of description to explaining below the work of the present invention.
For using above-mentioned purpose of the present invention, feature and advantage to become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Core idea of the present invention is, after starting workflow transactions, at first this resource is locked, for in same workflow transactions, amendment record is finished and generated to any persistence operation of workflow internal object all by the mode of revising Work stream data in the memory cache, but do not carry out real data persistence operation this moment, carry out but be deferred to when workflow transactions is submitted to, promptly when workflow transactions is submitted to, from the Work stream data of buffer memory, obtain the data of needs persistence according to the memory cache amendment record, system also carries out the backup of completion status example by plan target, thereby has effectively improved the treatment effeciency and the concurrent processing ability of Work stream data persistence.
With reference to figure 1, show the process flow diagram of the persistence processing method embodiment of a kind of Work stream data of the present invention, specifically can may further comprise the steps:
Step 1 starts workflow transactions;
Step 2 is for workflow resource locks;
Step 3, the Work stream data access according to the change of Work stream data in the described workflow transactions, generates the change record of memory cache data;
Step 4 is obtained the workflow of needs persistence and is revised data from the Work stream data of buffer memory according to the memory cache amendment record in the described workflow transactions;
Step 5 is revised data according to described workflow and is sent the persistence request;
Step 6 discharges the workflow resource lock;
Step 7 is submitted workflow transactions to.
Definition according to WFMC, workflow (Workflow) is exactly the business procedure that operates automatically, showing as the participant takes action according to rules to file, information or task, and make it between the participant, transmit, briefly, workflow is exactly a series of mutual linkings, business activity of carrying out or task automatically.Wherein, Work stream data is meant the status data of Workflow system internal object, and the Workflow system internal object is meant the internal object that Workflow system produces when carrying out flow process, comprise flow object, moving object, task object or the like, memory cache is the copy that is recorded in the Obj State information in the Installed System Memory.And workflow transactions is the workflow processing affairs of being expanded out by Workflow system on the db transaction basis.And affairs are working cells of a minimum, and affairs are all done the as a whole work of carrying out hit or miss.Because affairs are made up of several people's task usually, if therefore affairs are made as a whole thing one-tenth, then each personage in the affairs must be successful.If some failure in the affairs, then whole affairs also must be failed.Be that affairs have atomicity, consistance, isolation, persistent characteristics.
From on can learn that the described workflow transactions of the embodiment of the invention has following feature:
(1) have clear and definite transaction boundaries: for Workflow system, the initiation of affairs all is that it is controlled with finishing, and all know the border of workflow transactions.
(2) in affairs, can manage by the life cycle of persistence object by the mode of internal memory.In workflow transactions, the object (Work stream data) that needs persistence is all in Workflow system, and by the life cycle that Workflow system is managed it, request is optimized the mode that all can be by " memory cache amendment record " to persistence.
In practice, workflow transactions can start according to service request, starts workflow transactions, and prepares contextual information.Use in the present embodiment, when changing workflow internal object state and needing persistence, earlier the workflow internal object is added resource lock; Then, the mode with memory cache that triggers work at present stream internal object status data (being Work stream data) is carried out record; Change this Work stream data in the buffer memory internal memory, and generate Work stream data change record.
In the present embodiment, when workflow transactions is not submitted to, do not carry out the persistence operation, only when submitting workflow transactions to, just obtain workflow and revise data, just send the persistence request then according to these data by Work stream data change record.
For making those skilled in the art understand the present invention better, below Work stream data persistence processing procedure of the present invention is described by instantiation.
With the workflow activities example is example, supposes at work process flow in servicely, and the life cycle of an active instance is as follows:
(1) activity of constructing example, and active state is set is no initializtion;
(2) active state is set for not starting (i.e. Huo Dong init state);
(3) active state being set is (i.e. Huo Dong executing state) in service;
(4) active state is set for finishing (i.e. Huo Dong done state).
The variation of supposing these three states is in a workflow transactions, and the processing procedure of using present embodiment is as follows:
Step 1, startup workflow transactions;
Step 2, in internal memory the activity of constructing example;
The memory cache of (active instance create before) was not for having before Work stream data changed, and the memory cache that changes back (active instance is created the back) is for having, and the active instance state is a no initializtion.
The active instance state in the memory cache revised in step 3, record (2) (active state being set for not starting), and record active instance state is modified;
Active instance state in the memory cache before changing is a no initializtion, and the active instance state in the memory cache after the change is in service.
Step 4, record (3) (it is in service that active state is set) are revised the active instance state in the memory cache, and record active instance state is modified;
Active instance state in the memory cache before changing is not for starting, and the active instance state in the memory cache after the change is in service.
The active instance state in the memory cache revised in step 5, record (4) (active state being set for finishing), and record active instance state is modified;
Active instance state in the memory cache before changing is in service, and the active instance state in the memory cache after the change is for finishing.
Therefore step 6, according to the amendment record of Work stream data in the buffer memory, the change amount of finding this active instance is exactly the variable quantity of active instance state, sends the persistence request that creation state is the active instance finished to database.
By last example as can be seen, the method when adopting prior art then needs to submit to four persistence requests, promptly inserts data, for the first time more new data, more new data and the more request of new data for the third time for the second time; When adopting the embodiment of the invention, then only need to submit a data base persistence request to, thereby the present invention has effectively improved the efficient that the Work stream data persistence is handled.
With reference to figure 2, show the structured flowchart of the persistence treating apparatus embodiment of a kind of Work stream data of the present invention, specifically can comprise with lower unit:

For making those skilled in the art understand lock management mechanism among the present invention better, below be described by way of example.
Suppose that having a state is operating workflow activities, meets the following conditions:
1. when regular SwitchToB set up, activity A condition is revised as to be finished, the flow process successor activity B that circulates.
2. when regular SwitchToC set up, activity A condition is revised as to be finished, the flow process successor activity C that circulates.
In work at present stream affairs, the persistence manager sends two persistence requests simultaneously: persistence request RequestM modification is flowed when data cached, and regular SwitchToB sets up; Persistence request RequestN modification is flowed when data cached, and regular SwitchToC sets up.The application lock manager, first persistence request meeting is added exclusive lock to current workflow resource, and other persistence request judgment task stream resource is locked by other requests, then waits for the release of resource.So just avoided flow process concurrent concurrency conflict (blocking or deadlock) to occur.
Preferably, the priority of locking in the described lock management unit, time-out time, isolation level, granularity etc. can be provided with according to the ruuning situation of Workflow Management System.
