By Sergei Romanenko.This article describes the installation of Oracle Database 1.Release 1 (1. 2. 1.RAC on Linux (Oracle Linux 6.Virtual. Box (4. 2. Boats And Birds Gregory And The Hawk Download Movies . Highlights of this installation procedure. Smallest possible footprint in terms of RAM and disk space without noticeable performance hit; Short and fast way to get RAC installed and running. Only required operations included. If you can find more efficient way, please let me know; Both ASMLib and Udev shared disk configurations are covered; GUI- maximized, it is friendly for beginners, saves time for experienced veterans; Content. Introduction. This is my second article on Oracle RAC installed in Virtual. Box. The first one was about RAC version 1. Over last year, I became very active user of Virtual. Box. this is quite stable piece of software and I moved many aging physical computers in my household into virtual machines. A year ago I bought 1. GB of RAM for my laptop (paying about $1. Probably it is even more affordable now. Given this trend of galloping RAM size, the entry- level laptop computers with 1. GB are not far away from now. In this article I made adjustments for Oracle 1. Virtual. Box versions. Some steps were straightened or dropped making installation of 1. Your feedback is welcome, it helps to make the whole procedure simpler and faster. 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 (1. GB is recommended). Oracle Virtual. Box 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 6. Oracle Linux, version 6. Oracle 1. 2c Release 1, version 1. Using Virtual. Box you can run multiple Virtual Machines (VMs) on a single server. 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. Oracle Grid Infrastructure (Clusterware + ASM) and two Database instances all on a single server. System Requirements. GB of RAM; 4. 4 GB of free space on the hard disk + staging area for Oracle Linux and RAC downloads, about 9 GB; This procedure was tested on 6. Windows 7. The successful installation was also reported on Mac. Book Pro 2. 01. 1, 8. GB RAM, with OS X 1. Mountain Lion) and Virtual. Box 4. 2. 1. 8 - . Rudresh Rana who shared this information. It should be no problem using Virtual. Box on other Host OSes. Please let me know if you had success or problems in other OSes; Download Software. Download the following software. Virtual Machine Setup. In this exercise, we are using Virtual. Box installed on 6. Windows 7. We must define two virtual RAC nodes. We can save time by defining one VM, then cloning it when it is installed. Start Virtual. Box and click the "New" button on the toolbar. Enter the name "rac. OS "Linux" and Version "Oracle (6. Next" button. Set Base Memory to 3. MB, then click the "Next" button. Accept the default option to create a new virtual hard disk by clicking the "Create" button. Accept the default VDI type and click the "Next" button on the Create Virtual Hard Drive screen. Accept the default "Dynamically allocated" option by clicking the "Next" button. Accept the default file name and set size to "2. G", then click the "Create" button. The "rac. 1" VM will appear on the left hand pane. Click on the "Network" link on the right side. Make sure "Adapter 1" is enabled, attached to "Internal Network" or "Host- only Adapter". This inetrface will be used for public network, for example, for connection to the RAC datbase from other applications. More about networking will be explained later. On the screenshot below "Internal Network" is selected and name "pubnet" was given to this network. Then click on the "Adapter 2" tab. Make sure "Adapter 2" is enabled and attach to "Internal Network". Name this network "privnet". Then finally click on the "Adapter 3", enable it, and attach to "Bridged Adapter" or "NAT". This adapter will be used for internet. Then press "OK" button. Optionally, you can disable the audio card using "Audio" link. This will probably save some amount of space and avoid potential problems related to audio settings. Also if your system has 4 CPU cores or more, it will make sense to allocate 2 CPUs to the Virtual Machine. You can do that in "System" settings. The virtual machine is now configured so we can start the guest operating system installation. Guest Operating System Installation. Please note that during installation Virtual. Box will be keeping the mouse pointer inside VM area. To exit, press Right Control key on the keyboard. We will use Oracle Linux 6. ISO image downloaded earlier. Place the . iso file into the virtual DVD. Select "Storage" link on the right hand pane of the Virtual. Box Manager screen to open "Storage" screen. Then select DVD drive in the "Storage Tree" section. In "Attributes" section click on the DVD disk icon and choose DVD . Note that name of the file shows in the Storage Tree. Then press 'OK". Start the virtual machine by clicking the "Start" button on the toolbar. The resulting console window will contain the Oracle Linux boot screen. Proceed with the "Install or upgrade an existing system". Do not perform the media test. Choose "Skip" button. Continue through the Oracle Linux installation as you would for a normal server. On next three screens select Language, Keyboard, and Basic Storage Devices type. Confirm to discard any data. Note. For this sandbox setup we used domain name "localdomain". You can change it, but keep in mind to make same change throughout this exercise. Set "Hostname" to rac. Configure Network". In the Network Connections screen select "System eth. Edit". Make sure that "Connect automatically" is checked. Select "IPv. 4 Settings" tab; change Method to "Manual". Press "Add" and fill Address: 1. Netmask: 2. 55. 2. Gateway: 0. 0. 0. Press "Apply" then done. In the Network Connections screen select "System eth. Edit". Then check the box "Connect automatically". Select "IPv. 4 Settings" tab; change Method to "Manual". Press "Add" and fill Address: 1. Netmask: 2. 55. 2. Gateway: 0. 0. 0. When done, press "Apply". Finally select "System eth. Internet, then press "Edit". Check the box "Connect automatically". Select "IPv. 4 Settings" tab make sure the Method is set to "Automatic (DHCP)". Press "Apply" button. Close Network Connections screen and proceed to next setup screen. Select time zone. Type in Root Password: oracle. Select "Use All Space" type of installation and check "Review and modify partitioning layout". Edit size of lv_swap device to 1. MB; then edit size of lv_root to 1. MB. Press "Next". Confirm through warnings and create partitions. Keep defaults in Boot loader screen. In the software type installation screen select "Database Server" and check "Customize now" button. In the Customization screen select "Databases" and uncheck all items; select "Desktops" and check "Desktop" and "Graphical Administration Tools". Next and finish installation. When it comes back, there will be more setup screens obvious to handle. Don't create 'oracle' account, this will be done later. You can skip Kdump settings. Congratulations! The Linux has been installed. Tip. We will need to to use Terminal program (Main Menu | Applications | System Tools | Terminal) very often. You can save time by adding Terminal icon to the Panel or Desktop. Right click on Terminal menu item and select. Add this launcher to panel" or "Add this launcher to desktop". Check Internet Access. We will need Internet access because additional packages will be installed online. Open terminal (Main menu | Applications | System Tools | Terminal) and try to ping any Internet site, for example. If ping doesn't work, troubleshoot the problem using 'ifconfig' command and making changes in Network Connections. Linux desktop Main menu | System | Preferences | Network Connections). If you made changes in Network Connections, restart interface by rebooting VM or running these two commands. Then check the ping again. Oracle Clusterware Installation Prerequisites. Part 1.
