Embodiment approach 2

[0103] Image 6 For the flow chart of the second implementation mode of an online release method for AIX host memory provided by the embodiment of the present invention, please refer to figure 2 , in the second embodiment, the method also includes:

[0104] S103: Obtain the memory usage information of the AIX host after the memory identification, memory release and memory reorganization, which is called real-time memory usage information;

[0105] S104: Compare the real-time memory usage information with the memory usage information, and output a memory online release result.

[0106] The resource reorganization of the memory makes the memory resources that cannot be released before released, thereby achieving the online release of the memory resources. After the release is completed, the memory usage information at this time can be obtained again, and can be compared with the memory usage information in step S101. Compare to determine whether the online release of the memo...

Abstract

The invention provides an online release method, device and system for an AIX host memory, and relates to the technical field of processing of memories for operating systems. The method comprises the steps that memory using information of an AIX host is obtained; trigger information is output according to the memory using information, wherein the trigger information is used for indicating that the AIX host is subjected to memory capacity expansion according to an online capacity expansion standard, and after the memory capacity expansion is completed, memory recognition, memory release and memory reorganization are conducted. By means of the online release method, device and system for the AIX host memory, memory resources are released on line and reorganized, system down for maintenance is not needed, and the system does not need to stop running.

Description

technical field [0001] The present invention relates to the technical field of operating systems, in particular to the memory processing technology of the operating system, and specifically relates to an online release method, device and system for the memory of an AIX host. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] At present, each AIX ((Advanced Interactive Executive, advanced interactive execution, a set of UNIX-like operating system developed by IBM based on AT&T Unix System V) host will have a large number of job tasks, occupying a large amount of memory processing work. The tasks of the AIX host are completed After that, the memory resources occupied by the program cannot be automatically released in the first time, resulting in a serious waste of memory, and...
