View boot time in WindowsUnder Windows, you can use the systeminfo command to view.Here's what the site extracts about how long windows started.1.Windows systems can see how long it has been running from power on to now, which is useful, for example, in order to test the stability of the system, or for other reasons, to know how long the Windows operating system has been running, without the need for special tool software to view it, The operating system itself can do, the following to see the s

It also describes the communication methods between outlook and exchange and troubleshooting methods for common problems. : Http://www.5dmail.net/down/SoftList-2599.htm 11: Key Points for routine maintenance of the email system Description: effective maintenance is a prerequisite for ensuring stable system operation. This article will focus on all aspects of exchange maintenance, including database m

sent by the system administrator, and making high-level VM instance scheduling decisions. It also processes service level agreements and maintains system and user-related metadata. A cloud controller is composed of a group of services used to process user requests, verify and maintain systems, user metadata (Virtual Machine images and SSH key equivalence ), it can also manage and monitor the running of Virtual Machine instances. These services are configured and managed by the enterprise servic

corresponding log file can be used by new transactions. Note that this space reuse or truncation does not automatically reduce the physical size of the log file. If you need to reduce the space, you must use commands such as dbcc shrinkfile/DATABASE. The process of reusing a log space is called truncation. In simple mode, this process is called auto-truncate ). In this mode, logs usually do not need to be managed, but for a single large transaction, log files may grow very fast. In this case, i

Safety Summary Protecting the customer and ASP's data from malicious attacks (intentional or unintentional) is the entire content of security management. A clear understanding of what security management is and how the ASP and its customers can take it is critical, including what security policies are and what level of security needs to be achieved. You need to determine the SLA itself and the level of security it provides, and you need to take approp

log backup, every 3 months a full backup, every 15 minutes a log backup, when the disaster occurs, only through full backup and log backup to recover data, so although no data loss, But because the recovery of data took two days, resulting in 2 days of the banking system is not available, so the loss of a large number of customers. Another example is a domestic online video web site, using SQL Server as a backend relational database, the front-end uses no-sql, regularly no-sql data into the rel

itself, and the data synchronization method uses MySQL replication technology. MySQL replication is a log copy process, during the replication process one server acts as the primary server, while one or more other servers act as slave servers, simply to pull binary log files from the server to the master server, The log file is then parsed into the appropriate SQL to re-perform the operation of the master server from the server, in this way to ensure the consistency of the data.MySQL replicatio

When a Linux system encounters a problem, we not only need to view the system log information, but also need to use a large number of performance monitoring tools to determine which part (memory, CPU, hard disk ......) An error occurred. In Linux, all running parameters are stored in the virtual directory/proc. In other words, the data value obtained by the performance monitoring tool is actually derived from this directory, when system overestimates are involved, we can modify the relevant para
