Configuring Storage for Oracle Grid Infrastructure for a Cluster and Oracle RACThis chapter describes the storage configuration tasks that you must complete before you start the installer to install Oracle Clusterware and Oracle Automatic Storage Management Oracle ASM, and that you must complete before adding an Oracle Real Application Clusters Oracle RAC installation to the cluster. Reviewing Oracle Grid Infrastructure Storage Options. This section describes supported options for storing Oracle Grid Infrastructure for a cluster storage options. It contains the following sections See Also. The Oracle Certification site on My Oracle Support for the most current information about certified storage options. Overview of Oracle Clusterware and Oracle RAC Storage Options. There are two ways of storing Oracle Clusterware files Oracle Automatic Storage Management Oracle ASM You can install Oracle Clusterware files Oracle Cluster Registry and voting disk files in Oracle ASM disk groups. Oracle ASM is the required database storage option for Typical installations, and for Standard Edition Oracle RAC installations. It is an integrated, high performance database file system and disk manager for Oracle Clusterware and Oracle Database files. It performs striping and mirroring of database files automatically. A supported shared file system Supported file systems include the following Network File System NFS Note that if you intend to use NFS for your data files, then you should create partitions large enough for the database files when you create partitions for Oracle Grid Infrastructure. NFS mounts differ for software binaries, Oracle Clusterware files, and database files. Note Placing Oracle Grid Infrastructure for a cluster binaries on a cluster file system is not supported. You can no longer use OUI to install Oracle Clusterware or Oracle Database files on block or raw devices. See Also. My Oracle Support for supported file systems and NFS or NAS filers. Oracle ACFS and Oracle ADVM Support. Oracle Automatic Storage Management Cluster File System Oracle ACFS extends Oracle ASM technology to support of all of your application data in both single instance and cluster configurations. Oracle Automatic Storage Management Dynamic Volume Manager Oracle ADVM provides volume management services and a standard disk device driver interface to clients. Oracle Automatic Storage Management Cluster File System is layered on Oracle ASM through the Oracle Automatic Storage Management Dynamic Volume Manager interface. Oracle ACFS and Oracle ADVM are supported on Oracle Linux 5 and Red Hat Enterprise Linux 5 for Linux x. Linux x. 86 6. 4.

General Information About Oracle ACFSOracle Automatic Storage Management Cluster File System Oracle ACFS provides a general purpose file system. You can place Oracle Database binaries on this system, but you cannot place Oracle data files or Oracle Clusterware files on Oracle ACFS. Note the following about Oracle ACFS Oracle Restart does not support root based Oracle Clusterware resources. For this reason, the following restrictions apply if you run Oracle ACFS on an Oracle Restart Configuration. You must manually load and unload Oracle ACFS drivers. You must manually mount and unmount Oracle ACFS file systems, after the Oracle ASM instance is running. You can place Oracle ACFS database home file systems into the Oracle ACFS mount registry, along with other registered Oracle ACFS file systems. You cannot put Oracle Clusterware binaries and files on Oracle ACFS. You cannot put Oracle Database files on Oracle ACFS. You can put Oracle Database binaries and administrative files for example, trace files on Oracle ACFS. Oracle ACFS provides a general purpose file system for other files. General Storage Considerations for Oracle Grid Infrastructure and Oracle RACFor all installations, you must choose the storage option to use for Oracle Grid Infrastructure Oracle Clusterware and Oracle ASM, and Oracle Real Application Clusters Oracle RAC databases. To enable automated backups during the installation, you must also choose the storage option to use for recovery files the Fast Recovery Area. You do not have to use the same storage option for each file type. General Storage Considerations for Oracle Clusterware. Oracle Clusterware voting disks are used to monitor cluster node status, and Oracle Cluster Registry OCR files contain configuration information about the cluster. You can place voting disks and OCR files either in an Oracle ASM disk group, or on a cluster file system or shared network file system. Storage must be shared any node that does not have access to an absolute majority of voting disks more than half will be restarted. General Storage Considerations for Oracle RACUse the following guidelines when choosing the storage options to use for each file type You can choose any combination of the supported storage options for each file type provided that you satisfy all requirements listed for the chosen storage options. If you plan to install an Oracle RAC home on a shared OCFS2 location, then you must upgrade OCFS2 to at least version 1. Oracle recommends that you choose Oracle ASM as the storage option for database and recovery files. For Standard Edition Oracle RAC installations, Oracle ASM is the only supported storage option for database or recovery files. If you intend to use Oracle ASM with Oracle RAC, and you are configuring a new Oracle ASM instance, then your system must meet the following conditions All nodes on the cluster have Oracle Clusterware and Oracle ASM 1. Oracle Grid Infrastructure for a cluster installation. Any existing Oracle ASM instance on any node in the cluster is shut down. Raw or block devices are supported only when upgrading an existing installation using the partitions already configured. On new installations, using raw or block device partitions is not supported by Oracle Automatic Storage Management Configuration Assistant ASMCA or Oracle Universal Installer OUI, but is supported by the software if you perform manual configuration. If you do not have a storage option that provides external file redundancy, then you must configure at least three voting disk areas to provide voting disk redundancy. Guidelines for Using Oracle ASM Disk Groups for Storage. During Oracle Grid Infrastructure installation, you can create one disk group. After the Oracle Grid Infrastructure installation, you can create additional disk groups using ASMCA, SQLPlus, or ASMCMD. Note that with Oracle Database 1. Oracle Database Configuration Assistant DBCA does not have the functionality to create disk groups for Oracle ASM. If you install Oracle Database or Oracle RAC after you install Oracle Grid Infrastructure, then you can either use the same disk group for database files, OCR, and voting disk files, or you can use different disk groups. If you create multiple disk groups before installing Oracle RAC or before creating a database, then you can decide to do one of the following Place the data files in the same disk group as the Oracle Clusterware files. Use the same Oracle ASM disk group for data files and recovery files.
