Daily maintenance of Windows XP is a time-consuming and boring task. If Windows XP is smarter, it would be nice to perform automatic maintenance. Next, we will introduce you to the technique of enabling Windows XP to perform automatic maintenance through the. inf file. The specific content of automatic maintenance can be set at will, but it needs commands. For example, Xcopy is used for file backup, Defrag is used for disk fragmentation, and Del is us

You can use the task plan or the at. EXE command to complete the fragmentation in the task plan. Next, I will take the C drive as an example at a.m.. The specific operation steps are as follows:1. Open notepadProgram, Input: defrag.exe C:-v-F> C: \ Defrag-D.LOGExplanation: Use the defrag.exe command to sort out the C drive, output detailed results, and save the results to the C: \ Defrag-D.LOG in redirectio

space required for database maintenance. In our offline fragmentation of the Exchange Server database (Offline defrag), for a database file of size 20GB (EDB file plus STM file), we need an additional 20GB of space to hold the fragmented database files. In addition, when a database repair is required, usually we will make a backup on the server, these space, also need to consider.Therefore, the capacity of the RAID 5 system that holds the database fi

. Hidden parameters for Windows XP disk grooming Windows XP Disk Defragmenter Defrag.exe has a hidden parameter that is not even described in the XP Help file, which is-B, after using it, the Defrag tool will optimize the system's startup files and applications (XP can track how often the application is used to adjust its location on the disk) , so as to achieve the purpose of system optimization. You can enter in the command line prompt window:

CentOS7 Disable Transparent Huge Pages Transparent Huge Pages (THP) has been introduced since the CENTOS6 version, and this feature is enabled by default, starting with the CentOS7 version. Although THP is intended to improve memory performance, some database vendors recommend shutting down THP (such as Oracle, MARIADB, MONGODB, etc.) directly, which may cause performance degradation. First check the enabled status of the THP: [Root@localhost ~]# Cat/sys/kernel/mm/transparent_hugepage/

the GUID is the identifier for the power management scheme and we can execute the command "powercfg-list" to get it. As shown in Figure 1, if we want to remove the Power management scheme named JP, execute the command "Powercfg-delete 53d4577a-49c1-4867-ba59-7fd20316fa2d".
