Detailed Description

In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In order to solve the technical problems described in the background section, an embodiment of the present application provides an application takeover system, which includes a service application, an agent application, a port mapping module, and a scheduling module.

The business application program is an application program used for receiving a service request sent by a user and processing according to the service request. For example, the business application may be a database.

And the proxy application program is used for replacing the business application program to process the application program of the user service request when the business application program exits from operation. Furthermore, the proxy application may process the corresponding user service request in place of the at least one business application.

The port mapping module is used for mapping the port of the service application program to the proxy application program when the service application program requests the proxy application program to take over; when the agent application program can not process the user service request and requests the service application program to recover processing the service request, the port mapping module is used for canceling the port mapping of the service application program on the agent application program so as to facilitate the service application program to recover processing the user service request.

And the scheduling module is used for commanding the business application program to exit or start according to the corresponding request.

Based on the application takeover system, an embodiment of the present application further provides an application takeover method, which will be specifically described below with reference to fig. 1.

Referring to fig. 1, this figure is a flowchart of an application takeover method according to an embodiment of the present application.

S101: the business application sends a takeover request to the proxy application.

A takeover request is a request by a business application to request that a proxy application take over its service.

And the proxy application program is used for taking over the service business of the business application program instead of the business application program when the business application program exits from operation.

In order to improve the efficiency of taking over the service related to the service application by the agent application, an embodiment of the present application provides another implementation manner, in which before executing S101, the following steps need to be further executed:

a business application registers with the proxy application such that the proxy application obtains registration information for the business application.

The registration information comprises at least one of an access address and a port number of the business application program, a proxy service request list, starting information and a standard format of feedback information; the proxypable service request list includes proxypable service requests, run code, and types of return messages.

In addition, in order to further improve the efficiency of the proxy application taking over the service related to the service application, the embodiment of the present application provides another implementation manner, in which before executing S101, the following steps need to be executed:

the business application program judges whether the business application program is in an idle state or not;

if yes, executing S101; if not, the service application program is kept in the running state.

In this way, the agent application program will only replace the business application program in the idle state to perform the service business processing, so as to release the system resources occupied by the business application program in the idle state during the operation, thereby being beneficial to providing the resource utilization rate of the system.

S102: and the agent application program receives the takeover request sent by the service application program.

S103: and the agent application program sends the takeover determining message to the service application program, so that the service application program determines that the agent application program has received the takeover request sent by the agent application program according to the received takeover determining message.

S104: and the proxy application program sends a port change request to the port mapping module, so that the port mapping module maps the access port of the service application program to the proxy application program according to the port change request and returns a mapping completion message to the proxy application program.

The port change request is a request by the proxy application to request the port mapping module to map a port of the business application onto the proxy application.

The mapping complete message is a message that the port mapping module sends to notify the proxy application that the port change has been completed.

It should be noted that, S103 and S104 do not have a sequence, and S103 may be executed first, and then S104 may be executed; or executing S104 first and then executing S103; s103 and S104 may also be performed simultaneously.

S105: the proxy application sends the mapping completion message to the business application.

S106: the service application program receives the mapping completion message.

S107: the business application exits running.

S108: the proxy application performs the processing of the service request in place of the business application.

As an embodiment, S108 may specifically be:

s1081: the user sends a service request to the business application.

S1082: the port mapping module forwards the service request to the proxy application.

S1083: the agent application performs processing based on the received service request and registration information.

As an embodiment, S1083 may specifically be:

s1083 a: based on the received service request and registration information, the broker application confirms that the service request is in the proxiable service request list.

S1083 b: and processing the service request by the agent application program according to the running code.

The running code is located in the deputy service request list, and the running code may correspond to the corresponding service request one by one, so that the deputy application program executes different running codes for different service requests.

S1084: the agent application program obtains a processing result according to the type of the return message;

s1085: and the agent application program stores the processing result and the service request so as to obtain the processing result and the service request after the business application program is restarted.

As an embodiment, in order to ensure the security of storage and further improve the reliability of the system, S1085 may specifically be: and storing the processing result and the service request on at least one storage medium.

For example, the processing result and the service request are stored in a cloud service storage medium and an internal storage medium local to a company, respectively.

The above is a specific embodiment in which the proxy application processes a service request sent by a user instead of the business application.

However, since the proxy application can only process the service request in the deputy service request list in place of the service application, if the proxy application receives a service request that does not belong to the service request recorded in the service request in the deputy service request list, it is necessary that the proxy application should return the processing authority of the service request to the service application in order for the service application to process it.

Therefore, in view of the above situation, an embodiment of the present application further provides another implementation manner, in this implementation manner, when performing S108, if the proxy application confirms that the service request is not located in the brokerable service request list according to the received service request and the registration information, S108 may specifically be:

s108 a: the user sends a service request to the business application.

S108 b: the port mapping module forwards the service request to the proxy application.

S108 c: based on the received service request and registration information, the broker application confirms that the service request is not located in the proxiable service request list.

S108 d: and the agent application program sends a message that the current system is busy to the user.

Since the agent application program cannot take charge of the service request sent by the current user and needs to return the processing authority of the service request to the service application program, in the process, some time is spent, and therefore, the user cannot timely obtain the feedback result of the service request, so that in order to avoid the unintended waiting of the client, the current system can not quickly obtain the feedback result of the service request by sending a message that the current system is busy, and the user is informed to send the service request again after waiting for a period of time.

S108 e: and the agent application program sends the request for starting the service application program to a scheduling module.

Wherein the request to enable the business application comprises: the start-up information; the start-up information includes: resource requirements and a start code for starting the business application.

It should be noted that S108d and S108e do not have a sequence, and S108d may be executed first, and then S108e may be executed; or may be executed first in S108e and then in S108 d; s108d and S108e may also be performed simultaneously.

S108 f: and the scheduling module starts the service application program according to the received request for starting the service application program.

As an embodiment, S108f may specifically be:

s108f 1: and according to the received request for starting the service application program, the scheduling module acquires the resource requirement for starting the service application program.

S108f 2: judging whether the current system resource meets the resource requirement, if so, executing S108f 3; if not, go to S108f 4.

S108f 3: the scheduling module runs the start code of the start message to facilitate starting the business application.

S108f 4: and the scheduling module commands the application program to be quitted to quit running.

Wherein the application to be exited is at least one business application running under the current system.

As an embodiment, S108f4 may specifically be:

s108f4 a: and the scheduling module obtains a resource difference value between the current system resource and the resource demand.

S108f4 b: and the scheduling module takes the business application program which is in an idle state and has the resource occupation larger than the resource difference value as the application program to be quitted according to the resource difference value.

S108f4 c: and the scheduling module commands the application program to be quitted to quit operation so as to make the application program to be quitted quit operation.

S108f 5: return is made to execution S108f 2.

S108 g: and the scheduling module feeds back a message for determining starting to the agent application program.

S108 h: the agent application program receives the message which is sent by the scheduling module and used for determining the starting of the service application program;

s108 i: and the agent application program sends a port mapping canceling request to the port mapping module so that the port mapping module cancels the port mapping of the agent application program to the service application program according to the port mapping canceling request.

S108 j: and after the service application program is restarted, the service application program sends a request for forwarding the message to the agent application program.

S108 k: the agent application program forwards all message requests received in the period of taking over the service application program to the service application program according to the request for forwarding the message;

s108 l: the service application program receives all message requests forwarded by the agent application program;

s108 m: the service application processes all message requests according to all received message requests.

The all-message requests are multiple and include non-takeover message requests. Wherein a non-takeover request is a request that is not on the proxiable service request list and a non-takeover message request is a last message request of all message requests received.

As an embodiment, S108m may specifically be:

if yes, processing all message requests according to a receiving sequence;

if not, processing the non-takeover message requests, and then processing the rest message requests according to the receiving sequence.

Wherein, the receiving sequence refers to the sequence of receiving all message requests by the agent application program.

The above is a specific embodiment in which the proxy application returns the right to process the service request to the business application.

In the application takeover method provided by the application, the proxy application can replace the business application which has quitted operation to process the service business, so that the service business can still be processed through the proxy application when the business application quits operation. Therefore, the agent application program can take over the service business of the business application program with lower access frequency, so that the business application programs with lower access frequency quit running, and release the system resources occupied by the running business application programs, so that other business application programs can reuse the system resources, and the virtual machine resources are recycled, thereby avoiding the waste of the virtual machine resources, improving the utilization rate of the virtual machine resources, and further reducing the cost of the cloud business.
