Theres no better way to understand its benefitsincluding fault tolerance, security, load balancing, and scalabilitythan to experience them directly. Unfortunately, for many shops, the price of the hardware required for a typical production RAC configuration makes this goal impossible. A small two node cluster can cost from US1. US2. 0,0. 00. This cost would not even include the heart of a production RAC environment, the shared storage. In most cases, this would be a Storage Area Network SAN, which generally start at US1. For those who want to become familiar with Oracle RAC 1. Oracle RAC 1. 1g Release 2 system using commercial off the shelf components and downloadable software at an estimated cost of US2,2. US2,7. 00. The system will consist of a two node cluster, both running Oracle Enterprise Linux OEL Release 5 Update 4 for x. High Compressed Battlefield Hardline Digital'>High Compressed Battlefield Hardline Digital. Oracle RAC 1. 1g Release 2 for Linux x. ASMLib 2. 0. All shared disk storage for Oracle RAC will be based on i. SCSI using Openfiler release 2. Network Storage Server. Although this article should work with Red Hat Enterprise Linux, Oracle Enterprise Linux available for free will provide the same if not better stability and will already include the ASMLib software packages with the exception of the ASMLib userspace libraries which is a separate download. This guide is provided for educational purposes only, so the setup is kept simple to demonstrate ideas and concepts. For example, the shared Oracle Clusterware files OCR and voting files and all physical database files in this article will be set up on only one physical disk, while in practice that should be configured on multiple physical drives. In addition, each Linux node will only be configured with two network interfaces one for the public network eth. Oracle RAC private interconnect and the network storage server for shared i. SCSI access eth. For a production RAC implementation, the private interconnect should be at least Gigabit or more with redundant paths and only be used by Oracle to transfer Cluster Manager and Cache Fusion related data. A third dedicated network interface eth. Gigabit network for access to the network storage server Openfiler. Oracle Documentation. While this guide provides detailed instructions for successfully installing a complete Oracle RAC 1. Oracle documentation see list below. In addition to this guide, users should also consult the following Oracle documents to gain a full understanding of alternative configuration options, installation, and administration with Oracle RAC 1. Oracles official documentation site is docs. Network Storage Server. Powered by r. Path Linux, Openfiler is a free browser based network storage management utility that delivers file based Network Attached Storage NAS and block based Storage Area Networking SAN in a single framework. The entire software stack interfaces with open source applications such as Apache, Samba, LVM2, ext. Linux NFS and i. SCSI Enterprise Target. Openfiler combines these ubiquitous technologies into a small, easy to manage solution fronted by a powerful web based management interface. Openfiler supports CIFS, NFS, HTTPDAV, FTP, however, we will only be making use of its i. SCSI capabilities to implement an inexpensive SAN for the shared storage components required by Oracle RAC 1. The operating system and Openfiler application will be installed on one internal SATA disk. A second internal 7. GB 1. 5K SCSI hard disk will be configured as a single Volume Group that will be used for all shared disk storage requirements. The Openfiler server will be configured to use this volume group for i. SCSI based storage and will be used in our Oracle RAC 1. Oracle grid infrastructure and the Oracle RAC database. Oracle Grid Infrastructure 1. Release 2 1. 1. 2 With Oracle grid infrastructure 1. Release 2 1. 1. 2, the Automatic Storage Management ASM and Oracle Clusterware software is packaged together in a single binary distribution and installed into a single home directory, which is referred to as the Grid Infrastructure home. You must install the grid infrastructure in order to use Oracle RAC 1. Release 2. Configuration assistants start after the installer interview process that configure ASM and Oracle Clusterware. While the installation of the combined products is called Oracle grid infrastructure, Oracle Clusterware and Automatic Storage Manager remain separate products. After Oracle grid infrastructure is installed and configured on both nodes in the cluster, the next step will be to install the Oracle RAC software on both Oracle RAC nodes. In this article, the Oracle grid infrastructure and Oracle RAC software will be installed on both nodes using the optional Job Role Separation configuration. One OS user will be created to own each Oracle software product grid for the Oracle grid infrastructure owner and oracle for the Oracle RAC software. Throughout this article, a user created to own the Oracle grid infrastructure binaries is called the grid user. This user will own both the Oracle Clusterware and Oracle Automatic Storage Management binaries. The user created to own the Oracle database binaries Oracle RAC will be called the oracle user. Both Oracle software owners must have the Oracle Inventory group oinstall as their primary group, so that each Oracle software installation owner can write to the central inventory ora.
