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.
The Publish/Subscribe feature is that a subscriber is responsible for subscribing to a channel (channel) and a sender is responsible for sending messages to the channel. All subscribers to a channel receive messages whenever a message is sent to a given channel. The characteristics of publish and subscribe are that the subscriber is responsible for subscribing to a channel (channel) and the sender is responsible for sending messages to the channel. All subscribers to a channel receive messages whenever a message is sent to a given channel.
A Key-Value database is a simple NoSQL database, and a client can set a Value corresponding to a Key or delete a Key from the database according to a Key query Value. Key-value database software (e.g., Redis, etc.) generally integrates publish and subscribe functions, facilitating user usage.
Aiming at the problems of low efficiency and poor reliability of the configuration recovery process in the prior art, the configuration recovery method provided by the embodiment of the invention uses the configuration file in the database backup form and utilizes the characteristics of publishing and subscribing to ensure that all business processes can be configured and recovered in parallel, thereby improving the recovery efficiency.

102, the business process reads the configuration item of the business process from the candidate configuration database and judges whether the business process depends on the configuration of other business processes; if yes, executing step 103, and if not, executing step 104;
here, if the business processes a and B both need to restore their own configuration, and there are some configurations associated with each other between a and B, that is, if the B configuration entry of B does not take effect, the a configuration entry of a is affected and cannot take effect, that is, the a configuration entry of a depends on the B configuration entry of B. For example, if B's interface is not created, the configuration under that interface in a cannot be validated, and so on.
The above example is only a simpler implementation, and it should be understood that in actual implementation, business processes may be more numerous and their configuration-related associations may be more complex. For example, a configuration may be relied upon by multiple business processes.
Step 103, if the configuration item is dependent on the configuration item, temporarily storing the configuration item in the candidate configuration database, and subscribing the change message of the dependent configuration;
and 104, if not, writing the configuration item into an operation configuration database, and issuing a change message of the configuration corresponding to the configuration item.
Here, the configuration entry is written into the running configuration database, that is, the configuration entry is validated; correspondingly, the change message of the configuration corresponding to the configuration entry is published, that is, the message of the configuration entry which takes effect is published, so that the change message can be received by the service process which subscribes to the configuration entry.
Further, the method further comprises: at device startup, an empty candidate configuration database and an empty running configuration database are created.
Preferably, the candidate configuration database and the running database are non-relational databases of a Key-Value type. The business process can search Value according to the Key Value, and store the configuration item information in the Value.

It should be understood that the backup operation may also be triggered manually by a system administrator.
The configuration recovery method provided by the embodiment of the invention is characterized in that when equipment is started, a configuration file in a database backup form is imported into a candidate configuration database, a business process selects a configuration item of the business process from the candidate configuration database, when the configuration item is judged to depend on other configurations, the configuration item is temporarily stored in the candidate configuration database and subscribes a change message of dependent configuration, and after the change message of dependent configuration is received, the configuration item depending on the dependent configuration is read and written into an operation database. In the process of recovering the self configuration of the business process, if the relied configuration is found to be absent, the configuration is not discarded, but the self configuration can be recovered in the fastest time after the relied configuration is recovered, so that the problem of configuration dependence is solved, and the reliability of configuration recovery is improved.
