Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, 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 application.
Fig. 1 is a flowchart of a method for thermal upgrade of a computer management system based on data delay upgrade, which includes the following steps:
s101: the server side updates the dynamic link library; and when the client determines to restart, updating the dynamic link library.
In the process of upgrading the software system, both a Dynamic Link Library (DLL) file of the server and a DLL file of the client need to be updated, so as to update and upgrade the software system.
In the embodiment of the application, when the software system is upgraded, the server can immediately update the existing DLL file according to the DLL file to be updated, so that the software system is updated and upgraded at the server. The DLL file to be updated represents a new DLL file added with new functions or made up for system vulnerabilities.
In one embodiment, the server can directly adopt the DLL file to be updated to cover the existing DLL file, that is, directly replace the existing DLL file, and the updated DLL file includes the updated content of the software system and all original basic contents.
In the embodiment of the application, in order to prevent inconvenience to a user caused by adverse effects on the user due to software system upgrade in the process that the user uses an application program of the client, the client does not need to be updated synchronously with the server, that is, the client does not need to update the DLL file immediately, but can update the DLL file of the client after being restarted.
Specifically, after the update of the server is completed, the client can restart the IIS service in the same way when the client is restarted, and the original DLL file is covered by using the DLL file to be updated, so that the update of the DLL file of the client is realized.
In one embodiment, when the client restarts, the version of the DLL file of the client and the version of the DLL file of the server are checked respectively to determine whether the versions of the two DLL files are consistent.
If the versions of the two DLL files are not consistent, the DLL version of the client is usually lower than that of the server, namely the client is not updated in time. Therefore, the client can update the DLL file of the client according to the DLL file version of the server.
In one embodiment, since the client does not update the DLL file instantly, the server may store the DLL file to be updated by the client in a designated location of the application server. When the subsequent client is restarted to update, the DLL file to be updated can be obtained from the application server according to the designated position so as to update.
The client is updated in a delayed manner by updating the server immediately, so that inconvenience to a user caused by the fact that the user is forced to stop working due to the fact that IIS service needs to be restarted in the process that the user uses the client can be avoided.
S102: and the server side determines the value of the preset system parameter according to the updating condition of the dynamic link library of the client side.
In the embodiment of the present application, the DLL file updated by the server may include preset system parameters. The server side can determine the value of the system parameter according to the updating condition of the DLL file of the client side. Wherein the value of the system parameter can be used to represent the update status of the client.
It should be noted that, in a normal case, the update of the DLL file by the default client is delayed from that of the server, and therefore, the default initial values of the system parameters included in the DLL file updated by the server indicate that the DLL file of the client is not updated.
In the embodiment of the application, the server can acquire the update information of the client to the DLL file by checking the version information of the DLL file of the client, receiving the update information sent by the client after the update is completed, and the like.
If the server detects that the DLL file of the client is updated, the server can modify the value of the system parameter in the DLL file of the server so as to record the state that the client completes the updating of the DLL file through the change of the value of the system parameter.
By setting the system parameters, the server can record the updating condition of the DLL file of the client according to the values of the system parameters, so that the current updating condition of the client can be confirmed conveniently according to the values of the system parameters, and the asynchronous updating compatible processing of the client and the server is realized.
S103: and the server side determines the branch code to be executed from the dynamic link library updated by the server side according to the value of the system parameter.
In this embodiment, the updated DLL file of the server may further include two branch codes, which are the original code and the updated code, respectively. The original code represents the code of the last version (namely the original version) of the DLL file, and the updated code has the function and logic of the original version of the DLL file, and the updated code represents the code of the current version (namely the new version) of the DLL file, and the updated code has the function and logic newly added or modified in the updating.
Specifically, the two branch codes may respectively correspond to different values of the system parameter, and also respectively correspond to different update situations of the client. The original code corresponds to a default initial value of a system parameter and also corresponds to the non-updated condition of the client; the update code corresponds to a modified value of a system parameter and also corresponds to an updated condition of the client.
In the embodiment of the application, after receiving a request from a client, a server can determine which branch code of two branch codes should be executed, that is, a branch code to be executed, according to a value of a system parameter in a DLL file updated by the server.
Specifically, if the preset value of the system parameter is a default initial value, it indicates that the DLL file at the client is not updated, and the code logic of the DLL file is consistent with the original code of the server. Accordingly, the server side can confirm the branch code represented by the original code.
If the preset value of the system parameter is the modified value, namely the preset value is not the default initial value, the DLL file of the client side is updated, and the code logic of the DLL file is consistent with the update code of the server side. Accordingly, the server side can confirm the branch code represented by the execution updating code.
In the embodiment of the application, by setting the system parameter and the two branch codes corresponding to different values of the system parameter, the corresponding branch codes can be executed according to the updating condition of the DLL file of the client.
By adding the original code in the DLL file of the server, the compatible processing of the two branch codes can be realized, so that the client can still maintain a normal working state according to the logic of the original code under the condition of asynchronous update with the server, and the abnormal conditions such as operation errors and the like can be avoided.
The hot upgrading method of the software system ensures that the client does not need to be updated immediately, and can be updated after the client is restarted. Therefore, the process that the user uses the client side is not interrupted due to the restart of the IIS in the updating process, so that the client has to pause the work, and inconvenience is brought to the user.
In the method, the IIS service is not required to be restarted any more when the application service is updated, the patch update can be carried out on the project required to be updated at any time, any influence on the user is avoided, and the usability and the user acceptance of the software are greatly improved.
In one embodiment, the database structure may be updated synchronously with the client. Therefore, when determining that the DLL file of the client is updated, the server can update the database structure together. The updated database structure includes addition, deletion, modification of data fields, modification of preset data, and the like.
In one embodiment, in some cases, the update progress of the database may lag behind the update progress of the client, both failing to achieve full synchronization.
In this case, the server may determine the database information included in the request after receiving the request from the client. The server side can judge whether the database structure is updated or not according to the database information, and returns a corresponding result to the client side according to the updating condition of the database structure. The database information may include a data field requesting processing, preset data, and the like.
In one embodiment, the server may perform query in the database according to the data field, the preset data, and the like requested to be processed included in the database information, and determine whether a matched data field or preset data exists in the database, so as to determine whether the database structure is updated.
If the corresponding data field or preset data exists in the database, the structure of the database can be determined to be updated, and the server can normally process and respond to the request of the client.
If the corresponding data field or preset data does not exist in the database, it can be determined that the database structure is not updated, and the server cannot normally process the request of the client, so that the server can return corresponding prompt information to the client and inform the client of the condition that the database is not updated.
The method considers the abnormal condition that the updating of the database and the client are not synchronous, ensures that the software system can continue to operate under the abnormal condition by judging the request of the client in advance and setting a certain processing mechanism aiming at the abnormal condition, increases the compatibility of the server to the updating of the database and is beneficial to the normal operation of the software system.
Based on the same inventive concept, the foregoing method for thermal upgrade of a computer management system based on data delay upgrade provided in the embodiment of the present application further provides a corresponding device for thermal upgrade of a computer management system based on data delay upgrade, as shown in fig. 2.
Fig. 2 is a schematic structural diagram of a computer management system thermal upgrade device based on data delay upgrade provided in an embodiment of the present application, which specifically includes:
an update module 201, which updates the dynamic link library; the updated dynamic link library comprises two branch codes of an original code and an updated code;
the first determining module 202 determines a preset value of a system parameter according to an update condition of a dynamic link library of the client;
and the second determining module 203 determines the branch code to be executed from the updated dynamic link library according to the value of the system parameter.
