Embodiment
Fig. 1 generally is shown as conceptual diagram 10, use the system of common scheduler web service according to the preferred embodiments of the present invention.System 10 comprises the common scheduler web service that the scheduler web service winding module 20 of " snarling " or containing scheduling engine 22 provides.Like this, twine module 20 by the scheduler web service scheduler web service interface is offered different user and the computing equipment that hope obtains the managerial ability of scheduling engine 22, can contain different scheduling engine 22 and make them take on the scheduler web service.
Scheduler web service winding module 20 is played the part of different roles with wakeup web service winding module 24 in system 10.Scheduler web service winding module 20 provides utilizes scheduling engine 22, according to scheduling, and the common scheduler web service of the scheduler task that management application program 26 is carried out.For example, scheduler task can be to create so that carry out the program of the appointed task such as " generate weekly report " or " mass load store catalogs " by application program.
In the time will dispatching appointed task, create as traditional scheduler service and carry out usually, when current time and scheduling time during coupling, the scheduling engine 22 responsible schedule jobs that move.With the information stores of relevant schedule job in the scheduler registry (not shown).Scheduler registry can be for example XML file or database table.When the traffic control operation, scheduling engine 22 orders are carried out specified scheduled with the application program that schedule job interrelates.The management of scheduler task need not to be confined to the establishment and the command applications operation dispatching task of scheduler task, can also comprise for example asking cancellation specified scheduled, termination specified scheduled, the specified scheduled of recovery termination in the past, the management of obtaining the state of specified scheduled and removing task from scheduler registry.
On the other hand, wakeup web service winding module 24 plays dispatcher invokes person.When scheduling engine 22 ordered the application program 26 that interrelates with given wakeup web service winding module 24 to carry out specified scheduled, scheduler web service winding module 20 was sent to wakeup web service with instruction and twines module 24.Then, wakeup web service is twined module 24 responses, and it twines the instruction that module 20 receives from the scheduler web service, and invokes application 26 is carried out specified scheduled.Then, in order to be stored in the scheduler registry (registry), whether wakeup web service is twined module also can send status information to scheduler web service winding module 20 and scheduling engine 22 conversely, finish smoothly with the indication task.
In a preferred embodiment of the invention, scheduler web service winding module 20 and wakeup web service winding module 24 reside in the various computing equipment.So scheduling engine 22 can the far call application program.
Create schedule job by request, the scheduling engine 22 that the application program 26 in the system 10 itself can utilize common scheduler web service to provide asks application-specific according to specifying the scheduled for executing specified scheduled.The request of scheduling engine 22 is made by scheduler web service winding module 20.Like this, can long-rangely make request according to the scheduled for executing scheduler task.Although in many cases, the same application that schedule job is created in request is to finish the same application of relevant scheduler task, and this is not necessary.An application program can be asked one or more different application operation dispatching tasks, and these application programs can reside on the various computing equipment on the same computing equipment or in the distributed network.
Create the request of schedule job and also can be made by management and running user interface (UI) 28 by the user, management and running user interface (UI) 28 can reside on the remote computing device, also can reside on the resident superincumbent identical calculations equipment of scheduling engine.The request of scheduling engine 22 is made by scheduler web service winding module 20.Like this, can long-rangely make request according to the scheduled for executing scheduler task.
Can be called the supvr with making requesting users or the computing application program of creating schedule job.Make in first kind of situation of request in application program 26, can more specifically the supvr be called application server administrator.Though application server administrator can be to generate application requested automatically, it also can be to utilize application program to generate people's (that is artificial process) of request.Make by management and running UI 28 in second kind of situation of request the user, can more specifically the supvr be called common scheduler administrator.As illustrated below with reference to Fig. 3 B, common scheduler administrator may be convenient to dispatch task on a plurality of remote machines from single computing equipment.
By the similarity of considering that hotel wakeup is called out, can more easily understand the operation that module 20 and wakeup web service winding module 24 are twined in the scheduler web service.In typical hotel wakeup call scenario, the passenger makes the request of crying morning to the wake-up call service that the hotel provides.The passenger will receive at the fixed time and cry morning in second day morning, make the passenger can finish appointed task.In the present invention, the scheduler web service is twined module 20 and is received from gerentocratic request, subsequently, at the fixed time, " wake-up call " is sent to wakeup web service twine module 24.In this case, wakeup web service is played the part of the role that the application-specific on the responsible invokes application server is finished the client proxy of appointed task.
Because only need dispatch service of configuration on a computing equipment, common scheduler web service is than the easier configuration of traditional scheduler service.Want to utilize the application program on other computing equipment of function of scheduling engine 22 can the service of sharing of common scheduler web.So common scheduler web service can advantageously be applied in the distributed network environment.And, module 20 is twined in the scheduler web service and wakeup web service winding module 24 (for example provides the platform independence scheduler web service interface, as shown in Figure 2), make them can be for moving various types of client-server services of various operating systems.
