In terms of how Microsoft's smart cloud trigger gathers in China, Office 365 is also worth mentioning. Currently, Office 365 accounts for 23% of China's Saas market share, and its business has increased by 500% in the four years since it entered the Chinese market. It has served more than 1.8 million enterprise users and more than 20 million education users. Office 365 also meets the strictest

1. The SUMMARY
This document describes the basic steps for installing a high reliability scheme for configuring DB2 UDB Enterprise Serverv8.2 dual-machine SuSE Linux Enterprise Server v8.0 (SLES 8). The scheme is implemented as an HA implementation component in conjunction with the SLEs Volume Manager (LVM) and Veritas Cluster Server v2.2 (VCS 2.2).
2. Overview
This document assumes that the reader has understood the basic concepts of the HA scheme
If someone asks me about MySQL Backup advice my question would is if they have LVM installed or have some systems WI Th similar features set for the other operation systems. Veritas File System can do it for Solaris. Most SAN Systems would work as.
If someone asks me a question about MySQL backup, I'll ask first whether the operating system has LVM or other similar features installed in the software. The same functionality can be done with the

Group Machine backup solution
Sybase ase databases can use a group machine system for online and real-time security backup, it is also supported by all mainstream Hardware/platform vendors such as IBM, HP, SUN, NCR, DEC, NT, Veritas, and EMC. It is also widely used in key business application systems such as banking, post and telecommunications. In particular

Software: For storage devices that support the SCSI Reserve/Release command, use the SG command. A normal node uses the SCSI Reserve Command to "Lock" the storage device. When the faulty node finds that the storage device is locked, it knows that it has been driven out of the cluster, that is, it has encountered an exception, restart the instance to restore it to normal. This mechanism is also called Sicide (suicide). Sun and Veritas use this mechan

Hardware: Shoot The Other Node
encounters a "Split-brain" problem, we can use the "voting algorithm" to solve the problem of who obtains control of the cluster. However, this is not enough. We must ensure that the evicted node cannot operate on shared data. This is the problem to be solved by IO Fencing.
IO Fencing can be implemented in two ways: hardware and software:
