Summary of the invention
For the above-mentioned problems in the prior art, the invention discloses one and can keep the indeclinable method of resource ID in main preparation system full model synchronizing process.
The technical solution used in the present invention is as follows:
A kind of power scheduling main preparation system full model synchronously keeps the indeclinable method of resource ID, comprises the steps:
(1), in standby system, temporary pattern storehouse and real-time model storehouse is set up, one is equipped with for storing the next allowable resource ID storage unit of this model bank assignable least resource ID next time in two model banies, two model banies connect independently physical store respectively, wherein temporary pattern storehouse is for storing the model information of this mold sync, and real-time model storehouse is for storing model information during standby system cloud gray model.
(2) mold sync is started, first empty the model information in temporary pattern storehouse, again from real-time model library inquiry next allowable resource ID storage unit, and the assignable resource ID of the next one inquired is write the next allowable resource ID storage unit in temporary pattern storehouse.
By recording next allowable resource ID, if this mold sync process can be made need to distribute new resource ID all distribute backward from this resource ID, to ensure that the resource ID before this resource ID can not be reallocated, effectively avoid repetition, ensure the uniqueness of resource ID.
(3), circulation reads main system model resource object, according to request for information by corresponding model information stored in temporary pattern storehouse: read the model resource object that main system provides one by one, by the Uri of this object to resource ID corresponding to real-time model library inquiry; If successful inquiring, then the mapping of this resource object and Uri and resource ID can be write temporary pattern storehouse; If inquire about unsuccessfully, then to the next assignable resource ID of temporary pattern storehouse application, then the mapping of resource object and Uri and this resource ID is write temporary pattern storehouse, need add up and upgrade next allowable resource ID in temporary pattern storehouse simultaneously.
The present invention is before Resources allocation ID, Uri is first used to access real-time model storehouse, obtain existing resource ID, can ensure that the existing Uri repeated can not be reallocated resource ID and cause resource ID to change, prevent the problem that Uri identical in twice mold sync is mapped as different resource ID, also can ensure do not have the most newly assigned resource ID of Uri of corresponding resource ID can not repeat with existing resource ID simultaneously.Meanwhile, when accessing real-time model storehouse Gains resources ID, have employed a batch mode for inquiry, the impact on runnability can not be carried out real-time model library tape.
(4), all model resource objects read after, the model information in temporary pattern storehouse derived and import real-time model storehouse, terminating this mold sync.When importing model information to real-time model storehouse, all replace the original model information in real-time model storehouse, upgrade real-time model storehouse.The model resource object recorded in temporary pattern storehouse is compared with real-time model storehouse, and the resource ID of its correspondence of resource object that Uri repeats is consistent.
Model information described in above-mentioned steps comprises the Uri of model resource object and this resource object and the mapping relations of resource ID in standby system.
The invention solves the problem that the model resource object resource ID when being mapped to resource ID in twice mold sync process with repetition Uri is inconsistent, compared with prior art, respectively being applied in of reading model Information application is needed again not to be loaded into before Uri and resource ID map under effectively avoiding standby system, the problem that cannot normally run, the physical store various in enormous quantities (as a large amount of record resource ID graphic file) reducing record resource ID need change the workload of a time again, other are avoided directly to record the configuration file of resource ID, cause applying the problem that cannot normally run before again not revising.
