How to install ASMLIB from Oracle’s public YUM   http://oracleexamples.wordpress.com/2011/08/08/how-to-install-asmlib-from-oracles-public-yum/There are several ways to get ASMLIB, we can download it from the OTN here, or http://www.oracle.com/technetwork/topics/linux/asmlib/index-101839.html ,or we can download it from from ULN (Unbreakable Linux Network).Also it comes in the the Unbreakable Linux media, but if you are not subscribed to ULN and you are not using Unbreakable Linux then most people go to the OTN, where you have to select your Linux flavor and then navigate to the correct file according to the linux kernel and then download the 3 files one by one.I’m going to explain here how easy is to get it from Oracle’s public YUM repository (how to configure the public YUM repository?)Once you have the public YUM enabled do as root:1yum install o...

centos ssh无密码互信登录失败解决方法 最近使用RAC时，需要ssh无密登录， 配置好后，一直主机正常，另外一台，必需要密码才能登陆。配置ssh互信方式 都一样，却有一个主机有问题。后来发现， Oracle 用户家目录权限，不一样。# chmod 775 /home/oracle然后，就可以正常使用了。

Oracle10gR2 RAC实时应用集群(三)在Redhat Enterprise Linux5 x86_64下的集群(RAW+ASM篇) Oracle10gR2 RAC实时应用集群(三)在Redhat Enterprise Linux5 x86_64下的集群(RAW+ASM篇)(Oracle10gR2 + ClusterWare + RHEL5 + RAW + ASM)    RAC(Real Application Clusters,实时应用集群)，是多台主机组成的集群计算环境，是Oracle数据库支持网格计算环境的核心技术。    普通Oracle数据库，只能在一台主机上运行，数据库的实例和数据库文件都在一台主机上，是单实例单数据库。    RAC实时应用集群，可以在多台主机上运行，每台节点主机上运行一个数据库实例，通过共享存储磁盘访问相同的数据库文件，是多实例单数据库，单一节点故障不影响数据库的使用，负载能力也会随节点主机的增加而加强。    RAC集群的关键点:    1.共享存储    2.节点间需要内部通讯，以协调集群正常运行，所以每个节点需要提供外部网络与内部网络.    3.CRS集群软件: 需要集群软件(Clusterware)协调各节点.    4.集群注册文件(OCR): 需要注册集群，保...
