Abstract: A method for implementing replacing a startup screen of a smart POS device includes: checking, by the smart POS device, whether an updating screen completing flag exists when detecting a startup, if yes, displaying a corresponding startup screen according to a mirror file in a backup partition, otherwise, displaying a default startup screen according to a screen mirror file in a default startup screen partition; decrypting a received image data ciphertext by using a protection key, verifying data obtained by decrypting, if successful, generating a mirror file of the startup screen according to the data and storing the mirror file; applying for writing access to the backup partition; if the backup partition has a writing permission, clearing the updating screen completing flag and starting to write the stored mirror file in the backup partition; setting the updating screen completing flag after the mirror file is written in the backup partition.

Abstract: Described herein are systems, methods, and software to enhance the scaling of data processing systems in a computing environment. In one implementation, a method of operating a data processing management system includes monitoring a queue length in an allocation queue for data processing system, and generating a prediction of the allocation queue based on the monitored queue length. Once the prediction is generated, the data processing management system may modify an operational state of at least one data processing system based on the prediction of the queue length and a processing time requirement for data objects in the allocation queue.
