Description
SERVER PROGRAM HOT UPGRADING METHOD AND DEVICE
[1] TECHNICAL FIELD
[2] The subject matter relates to computer technology, and particularly, to a server program hot upgrading method and a server program hot 5 upgrading device.
[3] DESCRIPTION OF RELATED ART
[4] With a development of network technology, backend servers are playing a more and more important role in network environment. User requirements are also increased which causes an improved demand for 10 network backend servers. At the same time, the functions of the network backend server are constantly updated. Thus, the network backend server programs need to be constantly upgraded to meet the user requirements.
[5] Previously, the backend server disconnects the client each time the backend server upgrades and restarts, thereby causing an interruption of the 15 current service connection and affecting the client’s experience. At the moment the backend server restarts, all operations including file operation are forced to be interrupted, thereby causing a small amount of data to be loss. More seriously, if the interruption occurs when some key data is operated, the data cannot keep its integrity, thus causing the data to be lost and generate 20 errors.
[6] Take the client being connected to the backend server for registration for example. When a user uses the client to connect to the backend server for registration, if the backend server upgrades and restarts, the client will remind the user according to the connection state that the client is 25 disconnected with the backend server. The client cannot be connected to the backend server to continue the registration before the backend server restarts. After the background server updates and restarts, the user needs to perform 1 the registration again. Furthermore, since the registration is forced to be interrupted at the time the backend server updates and restarts, the user may not correctly continue the registration.
[7] In another case, when the user has been input key information 5 including username and the backend server updates and restarts, the key information is uploaded to the backend server and stored in the database. After the backend server updates and restarts, the user needs to perform the registration again and input the same username. Since the username has been existed in the backend server, the user may be reminded that the 10 username has been registered. However, the registration information corresponding to the username is incomplete, the user cannot use the username to log in the backend server, thus making the username to be ownerless and to occupy system resources, and also resulting that the user cannot use a satisfied username.

[42] The technical solution of the present invention is hereinafter described in detail with reference to the accompanying drawings.
[43] DETAILED DESCRIPTION
[44] It should be appreciate that the embodiments described herein are 15 only intended to illustrate, but not to limit the present disclosure.
[45] The technical solution of the present disclosure comprises: the server controls a processing instance A which is currently running to stop receiving business requests and to continue processing a current business request when the server program upgrades; the server creates a new processing instance B 20 by the updated server program, to process the business request received by the processing instance B; the server controls the processing instance exit after the processing instance A has finished processing the business request, and the server program finishes hot upgrading.
[46] Previously, the server needs to restart when the server program 25 upgrades. The server may disconnect the client when the server upgrades and restarts, thereby causing an interruption of the current service connection and a small amount of data to be loss, thus, the data cannot keep its integrity. 6 [47] The present disclosure provides a technical solution that the server doesn’t need to restart when the server program upgrades. No interruption of the service connection occurs when the server program hot upgrades, thereby preventing the data from being lost which is caused by an 5 interruption of the operations including file operation when the interruption of the service connection happens, and allowing the data to keep its integrity.
[48] FIG. 1 illustrates a first embodiment of a server program hot upgrading method comprising following steps: [49] At step S100, the server controls a processing instance A which is 10 currently running to stop receiving business requests and to continue processing a current business request when the server program upgrades; [50] The server keeps running the processing instance A which is currently running (that is, an old processing instance) and controls the processing instance A to continue processing the current business request 15 when the server program upgrades, thereby preventing the processing instance A to the process new business requests. Thus, the processing instance A stops receiving the new business requests.
[51] At step S200, the server creates a new processing instance B by the updated server program, to process the business requests received by the 20 processing instance B; [52] The server creates the new processing instance B by the updated server program. When the new processing instance B is created, the server controls the new processing instance B to process the new business requests, thereby preventing the service connection from being interrupted when the 25 server program upgrades. Thus, the user cannot sense that the server program upgrades.
[53] At step S300, the server controls the processing instance A to exit 7 after the processing instance A has finished processing the business request, and the server program finishes hot upgrading.
[54]The server controls the processing instance A to exit after the processing instance A has finished processing the business request, and the 5 server program finishes hot upgrading. The new business requests are processed by the processing instance B. That is, after the server program upgrades, there is only the processing instance B which processes the new business requests. It is foreseeable that the occupied resources are released when the processing instance A exits. 10 [55]In the embodiment, the new processing instance is created which processes the new business requests when the server program upgrades, at the same time, the old processing instance continues processing the current business request. Thereby, the server doesn’t need to restart when the server program upgrades, and no interruption of the service connection occurs. 15 Thus, the user cannot sense that the server program upgrades. Furthermore, since the server doesn’t need to restart, thus preventing the data from being lost which is caused by an interruption of operations including the file operation when the server restarts.
[5 6] FIG. 2 illustrates a second embodiment of a server program hot 20 upgrading method. Based on the above first embodiment, the step SI00 of “the server controlling a processing instance A which is currently running to stop receiving business requests and to continue processing a current business request when the server program upgrades” further comprises: [57]step SI 10, the server controls a daemon process to disable a 25 receiving functionality of the processing instance A which is currently running to cause the processing instance A to stop receiving the business requests, and further controls the processing instance A to continue processing the current business request, when the server program upgrades; [58] To manage the processing instances more conveniently, when the server program upgrades, the server controls the daemon process to manage the receiving functionality of the processing instance, disable the receiving functionality of the processing instance A which is currently running to cause the processing instance A to stop receiving the business requests. However, the processing instance A continues processing the current business instance to keep the service connection, thus, the user cannot sense that the sever program upgrades.
[59] The step S200 of “the server creating a new processing instance B by the updated server program, to process the business requests received by the processing instance B” further comprises following step: [60] step S210, the daemon process of the server program creates the new processing instance B by the updated server program and binds the processing instance B to a business request access port, and further controls the processing instance B to receive and to process the business requests.
[61] To ensure that the server program continues providing services for processing business requests, the server controls the daemon process to create the new processing instance B by the updated server program, and binds the processing instance B to the business request access port. At the same time, the server controls the processing instance B to receive and to process the business requests.
[62] In operation, the steps of this embodiment comprises following steps: [63] 1. the daemon process detects signal; [64] 2. when the daemon process detects an upgrading signal, the daemon process initials a new process from a same business request access port, that 9 is, the daemon process creates the new processing instance and binds the new processing instance to the business request access port.
[65] 3. disable the receiving functionality of the current process, after the current process has finished processing the current business request, the 5 current process exits, that is, the server disconnects the old processing instance to cause the old processing instance to stop receiving the business requests, at the same time, the old processing instance continues processing the current business request and exits the current business request is finished.
[66] Based on the advantage of the above embodiment, the processing 10 instances of this embodiment are managed by the daemon process. Thus, when the server program upgrades, the unified management of the daemon process can allow the processing instances to be switched more smoothly, allow the server to continue providing services for processing business requests when the server program upgrades, and further prevent the data from 15 being lost or generating errors when the server restarts.
[67] Furthermore, FIG. 3 illustrates a third embodiment of a server program hot upgrading method.

[69] The server program is divided into the access stratum and a backend 10 service stratum. The access stratum is configured to communicate with the client, receive the business requests from the client, and sends the received business requests to the backend service stratum. The backend service stratum provides services for processing the business requests by the processing instances. When the service program upgrades, the server controls an access stratum to stop sending the business requests to the processing instance which is currently running, that is, and to stop sending the business requests to the processing instance A, and further controls the processing instance A which is currently running to continue processing the current business request to avoid an interruption of the services for processing the business requests.

[72] The server creates the new processing instance, namely the processing instance B, and controls the access stratum to send the received business requests to the processing instance B. The processing instance B receives and processes the business requests, thereby allowing the new business requests to be successively received and processed when the server program upgrades.
[73] In operation, take a single server for example, the steps of this embodiments comprises: [74] 1. the server is deployed by separating the access stratum and the 11 backend service stratum [75] 2. when the server program upgrades, two backend processing instances are deployed, the request flows are leaded to the new backend processing instances by the access stratum, to cause the new backend processing instances to receive and to process the business requests; [76] 3. the old backend processing instance continues processing the current the business request and then exits after the business request is finished.
[77] Based on the advantage of the above embodiment, the access stratum of this embodiment allocates the business request, thereby allowing the new business requests to be leaded to the new processing instances when the server program upgrades, and allowing the processing instances to be switched more smoothly, thus avoiding an interruption of processing the business requests when the server program upgrades, further preventing the data from being lost or generating errors when the server program upgrades. Moreover, connection and data business can be switched on a single server.
[78] FIG. 4 illustrates a first embodiment of a server program hot upgrading device comprising: [79] a stop receiving module 100 configured to control a processing instance A which is currently running to stop receiving business requests and to continue processing a current business request when the server program upgrades; [80] The server keeps running the processing instance A which is currently running (that is, an old processing instance) and controls the processing instance A to continue processing the current business request when the server program upgrades, thereby preventing the processing instance A to the process new business requests. Thus, the processing 12 instance A stops receiving the new business requests.
[81] a new instance creating module 200 configured to create a new processing instance B by the updated server program, to process the business requests received by the processing instance B; [82] The new instance creating module 200 creates the new processing instance B by the updated server program. When the new processing instance B is created, the server controls the new processing instance B to process the new business requests, thereby preventing the service connection from being interrupted when the server program upgrades. Thus, the user cannot sense that the server program upgrades.

[84] The server controls the processing instance A to exit after the processing instance A has finished processing the business request, and the server program finishes hot upgrading. The new business requests are processed by the processing instance B. That is, after the server program upgrades, there is only the processing instance B which processes the new business requests. It is foreseeable that the occupied resources are released when the processing instance A exits.
[85] In the embodiment, the new processing instance is created which processes the new business requests when the server program upgrades, at the same time, the old processing instance continues processing the current business request. Thereby, the server doesn’t need to restart when the server program upgrades, and no interruption of the service connection occurs. Thus, the user cannot sense that the server program upgrades. Furthermore, 13 since the server doesn’t need to restart, thus preventing the data from being lost which is caused by an interruption of operations including the file operation when the server restarts.
