Problems solved by technology

[0003] The traditional memory dump mainly focuses on saving the state of the system or application when it hangs, so as to analyze the problem and locate the failure of the system or application in the hang state. However, this memory dump technology needs to suspend the system or application The running of the program cannot perform online memory backup. After the memory backup is completed, the system or application can continue to run, whi

Abstract

The embodiment of the invention discloses a memory processing method and memory management equipment. The method comprises the steps: receiving a memory dump request by the memory management equipment, wherein the memory dump request contains a process identification (PID), and memory pages of the process corresponding to the PID are needed dump memory pages; according to the PID, querying a process page table, and acquiring the memory pages of the process corresponding to the PID; if the attributes of the memory pages are read only attributes, carrying out backups of the memory pages in a memory; and sending a first backup request to external memory so that the external memory copies the backup memory pages into the external memory, wherein the first backup request contains the memory pages of the backups, and can ensure the data consistency while realizing online memory dump.

Description

technical field [0001] The invention relates to the field of computers, in particular to a memory processing method and a memory management device. Background technique [0002] The running data of the system memory can be saved through the memory dump, and after proper processing of these data, the relevant data corresponding to the running state of the system or program can be extracted from the memory, and then the purpose of analyzing the running status of the system can be achieved. [0003] The traditional memory dump mainly focuses on saving the state of the system or application when it hangs, so as to analyze the problem and locate the failure of the system or application in the hang state. However, this memory dump technology needs to suspend the system or application The running of the program cannot perform online memory backup. After the memory backup is completed, the system or application can continue to run, which may easily cause business interruption. [0...
