oracle asm 缩写

ASM                         Automated Storage Management 自动存储管理
ASM 是 Oracle 数据库 10g 中一个非常出色的新特性,它以平台无关的方式提供了文件系统、逻辑卷管理器以及软件 RAID(磁盘阵列) 等服务。ASM 可以条带化和镜像磁盘,从而实现了在数据库被加载的情况下添加或移除磁盘以及自动平衡 I/O 以删除“热点”。它还支持直接和异步的 I/O 并使用 Oracle9i 中引入的 Oracle 数据管理器 API(简化的 I/O 系统调用接口)。

RAC                        缩写    real application cluses 实时应用集群
RAC是real application clusters的缩写,译为“实时应用集群”, 是Oracle新版数据库中采用的一项新技术,是高可用性的一种,也是Oracle数据库支持网格计算环境的核心技术。

CRS                        Oracle Cluster Ready Service(Oracle集群就绪服务),简称CRS
在10g和11.1,Oracle的集群称为CRS(Oracle Cluster Ready Service), 在11.2,Oracle的集群称为GI (Grid Infrastructure) 对于CRS/GI,他们的一些核心进程的功能基本类似,但是在11.2,新增了很多新的Deamon进程。

从Oracle 10gR1 RAC 开始,Oracle推出了自身的集群软件,这个软件的名称叫做Oracle Cluster Ready Service(Oracle集群就绪服务),简称CRS。从Oracle 10gR2开始,包括最新的11g,Oracle将其更名为Clusterware(集群件),但通常意义上我们认为CRS = Clusterware = Oracle Cluster Ready Service = Oracle Cluster Software.
CRS一般用来搭建Oracle的并行数据库,即RAC,但除了与RAC的接口之外,CRS还提供了一组高可用性的应用程序接口(API),用来搭建一般应用程序的高可用集群,即一般我们常说的双机热备,比如使用CRS实现MySQL的双机热备。

OCR                       Oracle cluster register         Oracle Configuration Repository

CVU                       Cluster Verification Utility
在安装RAC的过程中,如果没有安装cvuqdisk包,那么集群检验工具(Cluster Verification Utility,CVU)就不能发现共享磁盘。而且,如果没有安装该包或者安装的版本不对的话,那么当运行集群检验工具的时候就会报“PRVF-10037 : Failed to retrieve storage type for “” on node “””或“Could not get the type of storage”或“PRVF-07017: Package cvuqdisk not installed”的错误。cvuqdisk的RPM包含在Oracle Grid Infrastructure安装介质上的rpm目录中。以root用户在RAC的2个节点上都进行安装
