Resource allocation method after system restart, system and related components

Abstract

The present application discloses a resource allocation method, system and related components after the system is restarted. The method includes: allocating the first part of resources from the resource pool to the initialization pre-application module; allocating the second part of resources from the resource pool to the cache module, So that the cache module restores the cache data to be restored in the initialization phase; cycle the following steps: determine whether the current remaining resources in the resource pool can meet the application requirements of the cache module in the preparation phase; if so, allocate the first Three parts of resources are given to the cache module; determine whether there is an IO recovery requirement; if so, allocate the fourth part of resources from the resource pool to the IO processing module according to the IO recovery requirement; determine whether the application requirements and IO recovery requirements in the preparation stage are fully met, If yes, break out of the loop. In this application, the method of resource allocation is changed to asynchronous, which ensures that the resource allocation can be carried out smoothly, and finally meets all resource allocation requirements.

Description

technical field [0001] The invention relates to the field of server control, in particular to a resource allocation method, system and related components after system restart. Background technique [0002] Currently, after the system is restarted, resources need to be reallocated. During the allocation process, there are several stages of initialization pre-application, preparation phase application, and recovery phase IO (Input / Output, input / output) application. Once the initialization pre-application phase takes up too much If the remaining resources in the resource pool cannot satisfy the preparation phase application or recovery phase application, the process will be interrupted and the system will not be able to carry out subsequent processes. [0003] Therefore, how to provide a solution to the above technical problems is a problem that those skilled in the art need to solve. Contents of the invention [0004] In view of this, the purpose of the present invention is...

[0002] Currently, after the system is restarted, resources need to be reallocated. The allocation process goes through several stages of initialization pre-application, preparation phase application, and recovery phase IO (Input / Output, input / output) application. Once the initialization pre-application phase takes up too much resources, the remaining resources in the resource pool cannot satisfy the preparation phase application or the recovery phase application, which will cause the process to be interrupted, and the system will not be able to carry out subsequent processes
