Real Application Clusters Multiple instances must have the same value.DB_FILES specifies the maximum number of database files that can be opened for this database. The maximum valid value is the maximum number of files, subject to operating system constraint, that will ever be specified for the database, including files to be added by ADD DATAFILE statements. If you increase the value of DB_FILES, then you must shut down and restart all instances accessing the database before the new

Purpose In this article we will demonstrate how to set up the Openfiler based server as an iSCSI storage device. We will then show how to use that iSCSI storage with an Oracle 10gR2 database with Real Application Clusters option. Openfiler (http://www.openfiler.com) is a powerful, intuitive browser-based network storage software distribution. Openfiler delivers file-based Network Attached Storage (NAS) and block-based Storage Area Networking (SAN) in a single framework. Openfiler

rhel 5.5 下安装11gR2时关于ntp的一点：若是不使用rhel自己的ntp服务，请在停止ntp服务后，务必进行如下的操作：# rm /etc/ntp.confor, mv /etc/ntp.conf to /etc/ntp.conf.org.否则，在grid infrastructure安装时，会提示你ntp服务没启动。。。 [@more@]
