Today's highly competitive business marketplace leaves little room for error in terms of availability, continuous operations, or recovery in the event of an unplanned outage. In today's connected world, an event that makes business data unavailable, even for relatively short periods of time, can have a major impact.
Hence, today's mission-critical database systems must operate 24x7 with the highest degree of availablility possible. As databvases increase in size, and ad hoc queries place more demands on the continued availability of the system, the time and hardware resources required to back up and recover databases grow substantially while the maintenance windows are either drastically reduced or disappear completely.
The instant split feature of EMC TimeFinder/Mirror software, together with suspend I/O features and IBM DB2 V9.7 for Linux, UNIX, and Windows, provide a highly available advanced database technical architecture to meet the highest possible demands of availability for your data. This article demonstrates the use of these features to create a consistent copy of a continuously available DB2 9.7 database to meet the increasing availability requirements demanded by today's business environment.

在当前激烈的市场竞争下，不允许在可用性、持续运行、意外停机恢复等方面出错。在今天的互联世界中，即使发生短时间的业务数据不可用事件，也会产生非常大的负面影响。
因此，当前的关键业务数据库系统必须具有高可用性，能够 24x7 不间断运行。由于数据库规模在不断扩大，同时 ad hoc 查询对系统的持续可用性提出更高的要求，对于备份及恢复数据库的时间与硬件资源的要求在快速增加，然而，维护时段却严重缩减，甚至完全没有维护时间。
EMC TimeFinder/Mirror 软件的即时拆分特性，以及 I/O 挂起特性，再加上 IBM DB2 V9.7 for Linux、UNIX、and Windows，提供了一个具有高可用性的高级数据库技术架构，能够满足您对数据可用性的最高要求。本文演示了如何利用这些特性来创建持续可用的 DB2 9.7 数据库的一致性拷贝，来满足当今业务环境不断增长的高可用性需求。
•简介
•系统配置
•为 DB2 9.7 数据库建立与拆分业务持续卷设备（BCVs）
•场景
•EMC Symmetrix 配置与管理
•可选的多站点 DB2 HA 拓扑
•在 AIX 和 Linux 中配置卷
•利用 db2inidb 重定位数据库
