Oracle RAC 11g Database on Linux Using VirtualBoxhttp://www.lab128.com/rac_installation_using_vb/article_text.html Home lab128 Oracle RAC 11g Database on Linux Using VirtualBox By Sergei Romanenko August - December, 2012 Like 210 people like lab128. Facebook social plugin This article describes the installation of Oracle Database 11g release 2 (11.2 64-bit) RAC on Linux (Oracle Linux 6.3 64-bit) using VirtualBox (4.1.14+). See also: Oracle RAC 12c Database on Linux Using VirtualBox. Introduction System Requirements Download Software Virtual Machine Setup Guest Operating System Installation Check Internet Access Oracle Clusterware Installation Prerequisites. Part 1 Install Guest Additions Oracle Clusterware Installation Prerequisites. Part 2 Network Setup Downloaded Oracle Installation Files Clone the Virtual Machine Create Shared Disks Install the Grid Infrastructure Install the Database Check the Status of the RAC Making Images of the RAC Database Restoring RAC from Saved Files Post Installation Optimization Clusterware and Database Monitoring Introduction If you want to get through all steps of the Oracle RAC installation and your laptop or desktop computer has 8 GB or more of RAM, then this is entirely feasible using Oracle VirtualBox as demonstrated in this article. You can get a running RAC system which can host a small test database. The created system is not, and should not be considered, a production-ready system. It's simply to allow you to get used to installing and using RAC and test various administration procedures. The article also explains how to save the images and restore RAC from the images in a matter of minutes. Even if you break your test system, it will be easy to restore. This article uses the 64-bit versions of Oracle Linux, version 6.3, and Oracle 11g Release 2, version 11.2.0.3. Using VirtualBox you can run multiple Virtual Machines (VMs) on a single server, allowing you to run both RAC nodes on a single machine. In addition, it allows you to set up shared virtual disks. The finished system includes two guest operating systems, two sets of Oracle Grid Infrastructure (Clusterware + ASM) and two Database instances all on a single server. The amount of disk space needed is about 32 GB, if you want to save images of the finished RAC, another 12 GB of the disk space will be needed. This article was originally inspired by the article "Oracle Database 11g Release 2 RAC On Linux Using VirtualBox" written by Tim Hall and published in his blog. Then it was almost entirely revised and reworked, now this article seems to have very little resemblance with the original work. Note. When this article was written, Oracle Database 11g Release 2 (11.2.0.3) for Linux 64-bit (both clusterware and database) was available through the Oracle support to licensed customers only. As happened in the past, the Oracle corporation was making the latest version available to general public pretty soon. So I thought that using the latest and greatest version at the moment, with many bugs fixed, will be the best way to go. But now is end of 2012 and 11.2.0.3 is still unavailable to general public, while this version is really much better than any older version. I apologize for this inconvenience and suggest to find any possible way to get this version. It doesn't make sense to fight issues and research workarounds for bugs already fixed. Ask your 1 of 84 12/9/2013 4:12 PM Oracle RAC 11g Database on Linux Using VirtualBox http://www.lab128.com/rac_installation_using_vb/article_text.html friends who have access to Oracle support to help. And, if you can, bother the Oracle corporation to make the latest version available for download. As of now, 11.2.0.3 can be downloaded in Oracle support site, in "Patches & Updates", then select "Latest Patchsets", then select "Oracle Database", then select "Linux x86-64", then select "11.2.0.3.0". The number of this patch set is 10404530, it is possible to jump to the download page using this number. This patch set is a full installation of the Oracle Database software. This means that you do not need to install Oracle Database 11g Release 2 (11.2.0.1) before installing Oracle Database 11g Release 2 (11.2.0.3). For installing RAC database you will need only 3 files: Oracle Database (includes Oracle Database and Oracle RAC), part 1: p10404530_112030_Linux-x86-64_1of7.zip 1.3G Oracle Database (includes Oracle Database and Oracle RAC), part 2: p10404530_112030_Linux-x86-64_2of7.zip 1.1G Oracle Grid Infrastructure (includes Oracle ASM, Oracle Clusterware): p10404530_112030_Linux-x86-64_3of7.zip 933M System Requirements 8 GB of RAM; 32 GB of free space on the hard disk; This procedure was tested on 64-bit Windows 7. Although there should be no problems using VirtualBox on other Host OSes. Please let me know if you had success or problems in other OSes; Download Software Download the following software. Oracle Linux; VirtualBox (Must be version 4.1.14 or later); Oracle 11g Release 2 (11.2) Software (64 bit). Please read the note about Oracle version in the Introduction section above. Virtual Machine Setup In this exercise, we are using VirtualBox installed on 64-bit Windows 7. Now we must define the two virtual RAC nodes. We can save time by defining one VM, then cloning it when it is installed. Start VirtualBox and click the "New" button on the toolbar. Click the "Next" button on the first page of the Virtual Machine Wizard.
