Oracle 11g 新特性Oracle Restartrestart高可用性
 
Oracle Restart improves the availability of your single-instance Oracle database. Oracle Restart
automatically restarts the database instance, the Automatic Storage Management (ASM) instance, the
listener, and ponents after a hardware or software failure or whenever your database host
computer restarts. Server Control (SRVCTL) is mand line interface to manage Oracle processes
that are managed by Oracle Restart on a standalone server.
 
This feature provides improved reliability and automated management of a single-instance Oracle
database and the management of any process or application running on the database server.
Oracle Restart 是 Oracle 11g 引入的新特性,是利用 Clusterware 为单实例提供高可用性保护。
在 Oracle 11g R2 中,restart database 依赖于 grid infrastructure 架构,在安装数据库软件之前,需要先安
装 grid infrastructure软件。
Oracle Restart database 可以利用 clusterware 提供的 srvctl crsctl 等工具管理数据库,在服务器或进程异
常终止时,grid infrastructure 会
自动进行重启,提供高可用性保护。
本文将以安装配置实验的形式详细介绍 Oracle 11g r2 restart database 步骤:

1、检查物理内存是否满足安装要求
[******@asm Server]#   grep MemTotal /proc/meminfo
MemTotal:      2229472 kB
2、检查swap空间是否满足安装要求
[******@asm Server]# grep SwapTotal /proc/meminfo
SwapTotal:     4292600 kB
[******@asm Server]# free
             total       used       free     shared    buffers     cached
Mem:       2229472     229844    1999628          0      18628     159852
-/+ buffers/cache:      51364    2178108
Swap:      4292600          0    4292600
