In the "Root script execution configuration" select "Automatically run configuration scripts" and check "Use root option", then type password oracle. Press "Next".
The results of prerequisite checks are shown on the next screen. You should see three warnings and one failure. The failure was caused by inability to lookup SCAN in DNS and that should be expected. Check "Ignore All" box and press "Next".
Press "Install" on the Summary screen.
Wait while installation takes place... When asked to confirm root scripts execution, answer Yes. The "root script" step was the longest one, so be patient!
We expect the verification phase to fail with errors related to low Host RAM, Swap File sizes, group mismatch for DISK1, and "udev information". These errors can be ignored. You can check errors opening log file. For example, for the log file shown below "gedit /u01/app/oraInventory/logs/installActions2013-09-30_10-25-44PM.log", then search for "Error".
Here is the example of offending lines from the log file for rac1 node:

Making Images of the RAC Database At any point earlier we could save the image of created virtual machine and then restor e it at will. Here we are going to save images of the newly created Oracle RAC system which we can restore in the same system or even hand over to another location and restore in a matter of few minutes! If all you need is saving and restoring images in the same VirtualBox setup, you can use Simplified Way of Saving/Restoring Images. The export of VM is a straightforward process and saving RAC images would be an easy task if not dealing with the shared disk. In my view the simplest way to handle that is by detaching shared disk from both nodes and taking care of these three parts (two self-contained VMs and one Shared disk) separately. In the end there will be three files: two files for VMs and a file representing the shared disk. These three files can be further zipped by your favorite archiver into one file which can be used for storage or transfer. After export is done, the shared disk can be easily attached back to the nodes. Same is true for the import of VMs back into VirtualBox along with the copy of shared disk - the shared disk is attached to the imported VMs as an extra step. Let's perform all these actions.
Clean Shutdown of RAC But first, we need to shutdown servers in nice and clean manner because we want save them in a robust state. Shutdown the database. As oracle user execute on any node:
$ . oraenv ORACLE_SID = [oracle] ? racdb The Oracle base has been set to /u01/app/oracle $ srvctl stop database ‐d racdb $
Shutdown the clusterware on the first node. As root user execute:
# . oraenv ORACLE_SID = [racdb1] ? +ASM1 The Oracle base remains unchanged with value /u01/app/oracle # crsctl stop crs ... CRS‐4133: Oracle High Availability Services has been stopped. #
Shutdown the clusterware on the second node. As root user execute:
# . oraenv ORACLE_SID = [racdb1] ? +ASM2 The Oracle base remains unchanged with value /u01/app/oracle # crsctl stop crs ... CRS‐4133: Oracle High Availability Services has been stopped. #
Shutdown both virtual machines. Wait until all VM windows are closed.
Detach Shared Disk and Make a Copy Of It In the VirtualBox Manager open Virtual Media Manager: Main menu | File | Virtual Media Manager. Then select the disk used by the RAC (rac_shared_disk1.vdi). Note that this disk shows as attached to rac1 and rac2 VMs:
Click on "Release" icon and then confirm in the pop-up window. Note that this disk now shows as "Not attached". Click on "Copy" to start Disk Copying Wizard.
Accept Virtual disk to copy and press "Next".
Accept Virtual disk file type as VDI and press "Next".
Select "Fixed size" and press "Next".
On the next screen you can set location and name of the new file. When done, press "Next".
On the Summary screen review details and press "Copy" to complete copying. Close the Media Manager when copying is done. Note. Do not try to copy .vdi file because the copy will retain same disk UID and VirtualBox will refuse to use it because there is already such disk. When copying trough the Virtual Media Manager, the new UID is assigned automatically.
Export VMs In the VirtualBox Manager select VM, then call Appliance Export Wizard: Main menu | File | Export Appliance. Exporting is generally as simple as saving a file. Export both VMs. Now you should have 3 files that can be further zipped into a single file with the size about 12 GB.
Re-attach Shared Disk to the Original RAC Setup Fix our current working RAC setup by re-attaching shared disk to rac1 and rac2 VM using "Storage" page. Don't forget to select correct controller before attaching the disk:
Press "Add Hard Disk" icon and use "Choose Existing Disk" to attach rac_shared_disk1.vdi . Once Shared disk is attached to both VMs, the RAC is ready to run.
Restoring RAC from Saved Files In this section we will import RAC from the saved files creating a second RAC system. Don't run both RAC at the same time because they will have same network attributes. Open Appliance Import Wizard: Main menu | File | Import Appliance. Choose the file and press "Next":
On the Appliance Import Settings different attributes of new VM can be changed. We are going to accept settings unchanged. It is interesting to note, that disks are going to be imported in VMDK format different from the original VDI format.
Wait until the VM is imported:
Import both VMs and copy Shared Disk rac_shared_disk1_copy.vdi file into the parent directory (Virtual VMs). This disk could be attached to both machines, but unfortunately current version (4.1.18) of VirtualBox doesn't preserve type of the disk then making a copy. Attach this disk to the either of imported VM, then select it and review disk information:
In the VirtualBox 4.1.18, the copied disk has "Normal" type. If you have a newer version and the type is "Shareable" then this bug has been fixed, and you can proceed to another VM. If not, de-attach the disk, then go to the Virtual Media Manager and change the disk type to "Shareable" as has been described above, then return to the Virtual machines and attached the Shared disk. Start new VMs. The clusterware should start automatically. You will need to bring up the database. Login as the oracle user and execute:
$ . oraenv ORACLE_SID = [oracle] ? racdb The Oracle base has been set to /u01/app/oracle $ srvctl start database ‐d racdb $
The RAC should be well and running!
Simplified Way of Saving/Restoring Images This is not a supported way to save/restore images in VirtualBox, but it is very simple and worked well. The restore is limited to the VirtualBox setup where images were saved. Stop both VMs. Find the location where VB stores images: Main menu | File | Preferences | General, "Default Machine Folder" box. For example: "C:\Users\sromanenko\VirtualBox VMs". Go to this folder and locate "rac1", "rac2" directories and "rac_shared_disk1.vdi" file. Make a .zip or .rar file containing these three items. If you don't have compressing tools and there is enough disk space, you can copy these three items to another location. The images are saved! In order to restore these images: Make sure VMs are stopped; Go to the "VirtualBox VMs" folder and delete "rac1", "rac2" directories, and "rac_shared_disk1.vdi" file; Restore these three items from the .zip file or copy from the location where these items were saved; The restored VMs are ready to run. That's it! Please send your feedback to: Back to the Top.
Comments Clifford Mathew says:
January 1, 2014 at 20:24, GMT Thank you for the instructions. During the GRID installation, I encountered error PRVF-7617 on "Setting Up Grid Infrastructure Step 8 of 19". Essentially, the multicast tests were failing. To identify and "workaround" (see CAUTION below) this error, the following steps were taken: 1. Executed the "runcluvfy" command as shown below from the shell prompt. This command file is located in the same directory as the "runInstaller". ./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -verbose 2. Turned off the ipv4 firewall using the following commands on both RAC nodes (rac1 and rac2) service iptables stop chkconfig iptables off 3. Restart both VMs, and re-execute Step 1 above to make sure errors are all cleared up 4. Continue with GRID install as is documented in this blog.
CAUTION: By shutting down the Firewall as I did, I made the system vulnerable from a security standpoint. A proper solution should involve configuring the "iptables" correctly to allow what Oracle wants. At this point I don't have the steps to do this "proper" solution. Notes: ====== If anyone wishes to disable IPV6, the steps below worked for me. IPV6 was NOT the cause for the above issues - so this is not a required step. vi /etc/hosts # and comment out references to any ipv6 addresses bu placing a "#" character in front, and save vi /etc/sysconfig/network # and add the lines given below, and save NETWORKING_IPV6=no IPV6INIT=no vi /etc/modprobe.conf # and add the line given below, and save (this file was not present, so I created it by saving) install ipv6 /bin/true chkconfig ip6tables off Restart the machines
Sergei Romanenko says:
January 1, 2014 at 23:52, GMT Thank you for the comment. Let me ask if you already disabled firewall (as described in "Network Setup" section) before getting PRVF-7617 error? Clifford Mathew says:
January 2, 2014 at 00:26, GMT A second cluvfy failure occurr ed at the end of GRID install (running from server rac1). This had to do with SCAN addresses and nslookup. To resolve this I installed BIND on one of the servers (rac1) using instructions the URL below: http://www.oracle-base.com/articles/linux/dns-configuration-for-scan.php (This page refers to a GUI DNS editor - I could not find that package, so that was not installed. All required DNS files were created when "service named start" command was issued. After starting "named", I followed the instructions and edited(or created the additional) files mentioned in that article. I only added the 3 SCAN addresses and localhost in the DNS database. These 3 SCAN addresses were then removed from /etc/hosts by commenting them out. Did a final "service named restart", then tried "nslookup rac-scan.localdomain" which resolved
the name to 3 IP addresses. After this clicked "Retry" button the installer window, and it succeeded. Clifford Mathew says:
January 2, 2014 at 00:29, GMT Hello Sergei, I might have missed the "disable firewall". Sorry. Sergei Romanenko says:
January 2, 2014 at 02:02, GMT No problem. It is good you mentioned that disabling firewall is not a best thing in any real world system. John Hong says:

January 9, 2014 at 17:22, GMT Hi, Nice document. I installed VM RAC 2 node and then I wanted to add a node. When I clone the machine and run clufy after successfully installing the GRID software, RAC3 is not showing as part of the RAC clusetr. Did I miss anything? I still went ahead and installed the database software successfully. Then when I ran the DBCA from RAC1 to create instance on RAC3, after entering the SYS username and password I got error message: service RAC1-vip:1521:RAC1 is not available. Check your username, password and make sure the listener is up and available" I don't understand this error. The scan and the regular listener are up and running. Did I do anything wrong?

January 15, 2014 at 20:31, GMT Great Document! Just a note: I got another failed prerequisite. PRVE-0426 : The size of in-memory file system mounted as /dev/shm is "____" megabytes
which is less than the required size of "2048" megabytes on node rac1, rac2 Just in case you get this error, modify the size of tmpfs using the following steps: # vi /etc/fstab Modify the tmpfs line to look something like: tmpfs /dev/shm tmpfs size=3g 0 0 save the file and quit remount tmpfs: mount -o remount tmpfs check changes: df -h Run prerequisite checks again. Solved. Enjoy! Costi says:
January 25, 2014 at 08:36, GMT Hi. I followed your tutorial, step by step and everytime I have different space avai. For example now I have almost free 6 GB, therefore I will have an error when installing the Oracle DB. Do you know why? Is it possible to be increased, otherwise I will have to take it again all over. Thank you Sergei Romanenko says:
January 25, 2014 at 19:37, GMT Required disk space can fluctuate and each new installation can be different, I didn't keep exact numbers, but it was not very big. This can be dependent on many things including Linux version, which keeps changing, yum online repository which also gets bigger over time and your VM will cache it. By the way, don't forget to release yum repository when you don't need it anymore: 'yum clean all'. I think it is possible to resize .VDI disk using 'VBoxmanage modifyhd' command and then modifying Linux partitions by 'GParted' but I never tried that. You can search Internet for details on that.

July 4, 2014 at 11:14, GMT Great. I create rac1 and rac2. How do you add a third node. Thanks Sergei Romanenko (http://lab128.com) says:
July 6, 2014 at 02:44, GMT Jim, Bill: Although I didn't try that, I would do these steps: - remove one node, say rac1, from the cluster; - clone rac1 to rac3, doing all needed changes (MAC addresses, hostname, IP addresses etc) described in the article; - add two new nodes (rac1, rac3) to the cluster. Removing and adding nodes is a standard procedure covered in Oracle documentation, also available on many web sites. Bill says:

Hi Sergei, The shared drives are not mounted on the Linux environment. Is there a way to check this? Do we need to do the mount of the shared storage manually? Thx, Anibal Sergei Romanenko (http://www.lab128.com) says:
August 15, 2014 at 17:54, 17:54 , GMT No. Check that shared drive is added and accessible: # ls /dev/sd* The output should be similar to this: /dev/sda /dev/sda1 /dev/sda2 /dev/sdb /dev/sdb1 Anibal Lopez says:
August 15, 2014 at 19:31, GMT Hi Sergei, The other problem is the SharedFolder. I have added the directory etc. When doing: [root@rac1 media] ls -l there is not oracle_sw. You know if I can check this too? Thx, Anibal Sergei Romanenko (http://www.lab128.com) says:
August 15, 2014 at 20:36, 20:36 , GMT In VirtualBox Manager, select VM and then open Shared Folders. Check that "oracle_sw" is in there. If not, see the document and add it. You may need to restart the VM if you made changes. Then in "/media" you should see sf_oracle_sw folder. Note that VB adds "sf_" prefix. Anibal Lopez says:

September 28, 2014 at 12:59, GMT Hi, Thanks for sharing. This is gold! Just want to share some experience while setting up 12.1.2 instead of 12.1.1. 1. You need a larger storage for both shared disk and rac vms or else you will run into issues when installing the database. i use 10gb for shared disk and 30gb for rac vms. I believe a 30% bump will do (I just want to be safe) 2. I hit an memory_target issue while starting up the RAC vm after the creation of database. I resolved it by increasing my vm memory to 4gb and set tmpfs to 3gb. Not sure whats the best way to resolve it but it's working for me atm. Thank you, Roger says:

December 19, 2014 at 14:49, GMT Hello Sergei and others, FYI, I got the same error even when I tried udev instead of ASMLib. And my friend also gets the exact same error. Guess this is the result of the current software components' combination. In the end, we decided going farward anyway despite of the errors. And surprisingly all is the good in the end:) Thank you again for your nice instrucitons! Best RuiXian Paul (www.webgeest.nl) says:
February 27, 2015 at 09:21, GMT Hi, Perfect description, step by step works smooth. Except 1 thing: the SSH connectivity during Installing Database step 7 of 13. Before doing anything on this screen, open up a terminal on both nodes. Check that: * you can ssh oracle@rac2 AND ssh oracle@rac1 two ways * you can also ssh to yourself! so ssh oracle@rac1 from rac1 AND ssh oracle@rac2 from rac2. This makes the entry for the 'own' machine come into the known_hosts * make sure that the authorized_keys contains the pub keys for BOTH hosts If this works fine, then ONLY click the Test button. And then Next. Do NOT click Setup button, because I think this messes up the configuration.
Thank you very much for this excellent post! Paul raj says:
March 7, 2015 at 15:40, GMT Hi, This is an awesome post. I did setup successfully. It would be nice if you write posts on node addition and node deletion and standby setup in 12c. Thanks. Rajan says:

April 13, 2015 at 06:08, GMT Sergei, Thank you very much for this great guide!, I created the labs using VirtualBox in Linux (Red Hat Enterprise Linux Server release 6.5), as per other comment posted here I also used 12.1.0.2, but to get it working I had to increase memory up to 4 gb per each node, and also set tmpfs to 3gb.

August 13, 2015 at 19:28, GMT Excellent tutorial. - I used Oracle Linux 7 for 64 bit and I found that at the section titled "Udev Configuration" should be # /usr/lib/udev/scsi_id -g -u -d /dev/sdb instead of: # /sbin/scsi_id -g -u -d /dev/sdb

December 15, 2015 at 11:49, GMT One basic question : Why are you using both asmlib and udev ? Only one of them should be needed. abi says:
January 18, 2016 at 03:55, GMT Super Article. Thanks a Ton. Really useful. I was able to setup racdb properly for which I was struggling for many days. Kirk says:

March 14, 2016 at 19:32, GMT Somehow the instructions in the last part of section "Create Shared Disks" did not work for me. I could not see anything when I used "Choose existing disk" option to attach the newly created shareable virtual disk to the other VM. can I get some help? thanks!
