Embodiment Construction
[0039] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.
[0040] The operation log-based model data recovery method provided by the embodiment mainly includes three parts. The first part is to establish a notification mechanism on the underlying model network to capture log information during model operation; the second part is to establish an efficient persistence mechanism. To access the model operation log information generated in the notification mechanism; the third part is the specific data recovery process, which is used to read the log information of the persistent medium and perform corresponding processing to achieve t...

The invention discloses a model data recovery method based on an operation log. The model data recovery method comprises the following steps of: constructing a log system on the basis of the modelingoperation record, wherein the log system collects modeling operation information through a model information notification mechanism, and organizes the collected modeling operation information by taking all modeling operation information in a time period from a modeling operation request to response to the modeling operation request as a log persistence unit; persisting each log persistence unit into a log persistence engine; and during data recovery, reading the log persistence units in sequence to form a modeling operation record set based on a time sequence. The model data recovery method can realize recovery of the model data.
Description
technical field [0001] The invention relates to the technical field of data recovery, in particular to an operation log-based model data recovery method. Background technique [0002] Model data recovery is mainly used in the two scenarios of modeling transaction rollback and model data loss, and is a must-have function in complex modeling systems. It guarantees the integrity and correctness of data, and at the same time provides a backup for important data. During the modeling process, the modeler conducts model operations in custom-scoped transactions. Once the transaction needs to be canceled or terminated abnormally, the model data needs to be restored to the state at the beginning of the transaction. This condition may arise from a normal cancel operation, or from a failure or exception encountered. Among them, the failure may be caused by software and hardware damage such as process crash, network disconnection, and disk bad sectors. However, after operations such a...
