Description
Technical field
The invention belongs to technical field of control method more particularly to a kind of distributed system workflow processing method and work
Flow automotive engine system.
Background technique
Workflow can be completely or partially by the business procedure of computer automatic execution, in the process, document, information
Or task is transmitted according to scheduled rule, mutual co-ordination between enterprise personnel, application software, to realize business event stream
Journey overall goals to be achieved.Workflow Management System, which refers to, operates in one or more software for being known as workflow engine
On, a set of software systems for defining, realizing and management work is run, it and work executor are interactive, promote workflow
The execution of example, and the operating status of control work flows.Currently, the mode that traditional working flow products are generally taken is centralization
Process, although being easier to realize maintenance and management, but there is poor expandability, product reliability and availabilities
It is low, safety poor the problems such as poor with other application integration.
In conclusion problem of the existing technology is：Traditional workflow scalability is poor, product reliability, availability
It is low, the problems such as integration is poor, and safety is poor.
Summary of the invention
In view of the problems of the existing technology, the present invention provides a kind of distributed system workflow processing method and work
Flow automotive engine system.
The realization process of distributed system workflow processing method and workflow engine system of the invention is as follows：The distribution
Formula system workflow processing method and workflow engine system are provided with Workflow Meta-model creator, Workflow Meta-model creation
Device and management by district device are connected with each other, and management by district device is connected by way of link with communications adapter.Communications adapter
It is connected also by way of link respectively at workflow engine, process instance library adapter and event handler.Wherein, work
Make stream engine to draw in two sub-sections, is master engine and auxiliary engine respectively.Master engine by oneself internal server with
Auxiliary engine connection, auxiliary engine by server with itself corresponding to database and the corresponding connection of memory.
Advantages of the present invention and good effect are：The distributed system workflow processing method and workflow engine system are logical
Optimal Decomposition workflow activities are crossed, different workflow engines is assigned them to and is handled, to solve traditional work
The problems such as poor scalability, product reliability, availability are low, and integration is poor, and safety is poor is flowed, the work of workflow processing is improved
Efficiency, accuracy, compatibility and safety.

Specific embodiment
In order to further understand the content, features and effects of the present invention, the following examples are hereby given, and cooperate attached drawing
Detailed description are as follows.
Structure of the invention is explained in detail with reference to the accompanying drawing.
A kind of distributed system workflow processing method and workflow engine system, the distributed system workflow processing side
Method and workflow engine system are provided with Workflow Meta-model creator 1, Workflow Meta-model creator 1 and management by district device 2
It is connected with each other, management by district device 2 is connected by way of link with communications adapter 4.Communications adapter 4 also passes through link
Mode is connected respectively at workflow engine 3, process instance library adapter 5 and event handler 6.Wherein, workflow engine 3
It draws in two sub-sections, is master engine 7 and auxiliary engine 8 respectively.Master engine 7 passes through oneself internal server 9 and auxiliary
Engine 8 connects, auxiliary engine 8 by server 9 with itself corresponding to database 10 and the corresponding connection of memory 11.
The working principle of the invention is：
The various types collection of basic object-oriented is contained in Workflow Meta-model creator 1, covers workflow, work
Dynamic, conversion, participant and related categorical data.The object covers whole process actions, the Yi Jigong of this definition process
Make stream related data etc., these data need to transmit on stream, or swap between each application program, these numbers
During being stored in workflow by way of variable or constant.By Workflow Meta-model creator 1, work is created
Correlation types data, these data such as various relevant parameters, the activity used required for during stream pass through Workflow Meta-model
Creator is sent to management by district device after having created.
In the process implementation procedure of workflow, the application request sent to workflow engine 3 has very much, passes through split blade type
These requests are carried out fragment according to activity, distribute to each workflow engine 3 and handled by manager 2, relevant data letter
Breath must be sent to workflow engine 3 according to activity command and be handled.
Communications adapter 4 is passed to by the activity that 2 fragment of split blade type manager is over.The letter that communications adapter will obtain
Breath data are transported to parallel process instance library adapter 5 and event handler 6.During workflow engine 3 handles data, have
Multiple process instance libraries adapter 5 is run parallel, and the process instance under operating status is stored in process instance library adapter 5,
The result that activity executes is stored in process reality in activity executes by the execution efficiency that workflow engine 3 is improved by transporting
It in example library adapter 5, when to there is similar process instance to execute later, can be called, to save a large amount of
It the time for repeating calling operation, improves work efficiency.Event handler 6 is to receive all workflow engines to send over
The data informations such as event send an event to workflow engine and are handled, and movable event or process are changed
New events be sent to workflow engine 3 and be updated, so that workflow engine 3 be assisted to carry out the activity data processing of event.
After completing above-mentioned steps, communications adapter 4 sends the activity handled well in workflow engine 3.Workflow
Engine 3 divides for master engine 7 and auxiliary engine 8.7 trigger flow life event of master engine, being obtained by communications adapter 4 should
All information of activity process, obtain the template process pre-set, product process example, by the activity flow instance and
Relevant information, which is packaged together, is sent to auxiliary engine 8 by server 9.Auxiliary engine 8 is according to flow template and related data
Information executes example, and generates relevant information and be sent in database 10 and memory 11 storage in time by server 9.
The above is only the preferred embodiments of the present invention, and is not intended to limit the present invention in any form,
Any simple modification made to the above embodiment according to the technical essence of the invention, equivalent variations and modification, belong to
In the range of technical solution of the present invention.
