Oracle 11gR2 RAC on Windows 2008 using VMWARE

Oracle 11gR2 RAC on Windows 2008 R2 using VMWARE
Network Configuration

Name the network connection as “public” and “private”

Amend the C:\windows\system32\drivers\etc\hosts file to contain the following information.       localhost.localdomain   localhost
# Public   rac1.localdomain        rac1   rac2.localdomain        rac2
#Private   rac1-priv.localdomain   rac1-priv   rac2-priv.localdomain   rac2-priv
#Virtual   rac1-vip.localdomain    rac1-vip   rac2-vip.localdomain    rac2-vip
# SCAN   rac-scan.localdomain rac-scan

Addition changes:First, ensure the public interface is first in the bind order:

  • Open the "Network Connections" dialog by right-clicking on the "Network" .
  • Press ALT and select the "Advanced > Advanced Settings..." menu option.
  • On the "Adapters and Bindings" tab, make sure the public interface is the first interface listed.
  • Accept any modifications by clicking on the "OK" button and exiting the "Network Connections" dialog.

Second, disable Windows Media Sensing for TCP/IP:
  • Backup the Windows registry.
  • Run the Registry Editor (Regedt32.exe) and find the following key:

  • Add the following registry value:

Value Name: DisableDHCPMediaSense
Data Type: REG_DWORD -Boolean
Value: 1

Third (Optional, not required), disable IPV6:

Add the following registry value:
Value Name: DisabledComponents
Data Type: REG_DWORD -Boolean
Value: 1
  • Restart Both Nodes
  • This change will not take effect until the computer is restarted.
  • Open the "Network Connections" dialog by right-clicking on the "Network" – “Properties” – Change adapter settings .
  • Uncheck “Internet Protocol Version 6(TCP/IPv6)” for each adapter:
  • Press ALT and select the "Advanced > Advanced Settings..." menu option.
  • Uncheck “(TVPIP/IPv6)” boxes:

Create Shared Disks
  • Add 5 disks, SCSI, Independent, Allocate all disk space now, Virtual device node from SCSI 1:1 to SCSI 1:5.

(If Shared disk configure fails, RAC will be not installed on the second node, and you’ll see error message under $CRS_HOME/log/diag/asm/+asm/+asm2/trace/alert_+asm2.log.
To bypass it, you can edit the setting of the second VM node, add disk, using existing disk created by node 1.)
  • Edit the contents of the “RAC1\RAC1.vmx" file using a text editor, making sure the following entries are present. Some of the tries will already be present, some will not.

disk.locking = "FALSE"
diskLib.dataCacheMaxSize = "0"
diskLib.dataCacheMaxReadAheadSize = "0"
diskLib.dataCacheMinReadAheadSize = "0"
diskLib.dataCachePageSize = "4096"

  • Start the RAC1 virtual machine by clicking the "Power on this virtual machine" button on the VMware Server Console. When the server has started, log in so you can partition the disks.
  • Prior to partitioning the disks, you must enable disk automounting. To enable automounting do the following command at the command prompt, then restart the server.

C:\> diskpart
DISKPART> automount enable
  • Partition the disks using the "DiskPart" utility. To get alist of the current disks do the following.


Microsoft DiskPart version 6.0.6001
Copyright (C) 1999-2007 Microsoft Corporation.
On computer: RAC1

DISKPART> list disk

 Disk ###  Status      Size     Free     Dyn  Gpt
 --------  ----------  -------  -------  ---  ---
 Disk 0    Online        24 GB      0 B
 Disk 1    Online        10 GB    10 GB
 Disk 2    Online        10 GB    10 GB
 Disk 3    Online        10 GB    10 GB
 Disk 4    Online        10 GB    10 GB
 Disk 5    Online        10 GB    10 GB

  • In the diskpart utility we will perform the following commands.

automount enable
select disk 1
create partition extended
create partition logical
select disk 2
create partition extended
create partition logical
select disk 3
create partition extended
create partition logical
select disk 4
create partition extended
create partition logical
select disk 5
create partition extended
create partition logical
(If you want to create partition for a raw disk, create partition extended first, then create simple volume in disk management.)
  • Create ASM disk group for both nodes with the tool asmtoolg under “asmtool” folder of the installation CD
  • Click “Next” in “asmtool operation” window:
  • Select 5 disks created and click Next:
  • Edit the attributes then click “Next”:
  • Click “Finish”:

  • Turn off windows firewall
  • Shut down the RAC1 virtual machine and copy the RAC1 virtual machine.
  • Edit rac1.vmx change displayName = "RAC2".
  • Start rac2, modify machine name,ip address and restart rac2, rac1.
  • Once the RAC2 virtual machine has restarted, start the RAC1 virtual machine. When both nodes have started, check they can both ping all the public and private IP addresses using the following commands.

ping rac1
ping rac1-priv
ping rac2
ping rac2-priv
on Rac1:
net use \\rac2\c$
On Rac2:
Net use \\rac1\c$

Prior to 11gR2 we would probably use the "" utility in the clusterware root directory to check the prerequisites have been met. If you are intending to configure SSH connectivity using the installer this check should be omitted as it will always fail. If you want to setup SSH connectivity manually, then once it is done you can run the "" with the following command.
runcluvfy.bat stage -pre crsinst -n rac1,rac2 -verbose

Install the Grid Infrastructure
Start the RAC1 and RAC2 virtual machines, login to RAC1 as the oracle user and start the Oracle installer.
Select the "Install and Configure Grid Infrastructure for a Cluster" option, then click the "Next" button.
Select the "Typical Installation" option, then click the "Next" button.
On the "Specify Cluster Configuration" screen, click the "Add" button.
Enter the details of the second node in the cluster, then click the "OK" button.
Click the "Identify network interfaces..." button and check the public and private networks are specified correctly. Once you are happy with them, click the "OK" button and the "Next" button on the previous screen.

Change the software location if you like, choose "Automatic Storage Manager" as the cluster registry storage type. Enter the ASM password and click the "Next" button.

You’ll see 5 disks in the candidate. Set the redundancy to "External", select all 5 disks and click the "Next" button.
If you are happy with the summary information, click the "Finish" button.
Wait while the setup takes place.

Wait for the configuration assistants to complete.
If you choose advanced installation:

Install the database
Uncheck the security updates checkbox and click the "Next" button.
Accept the "Create and configure a database" option by clicking the "Next" button.
Accept the "Server Class" option by clicking the "Next" button
Make sure both nodes are selected, and then click the "Next" button.
Accept the "Typical install" option by clicking the "Next" button.
Accept the install locations. The storage type should be set to "Automatic Storage Manager". Enter the appropriate passwords and database name, in this case "rac".
We’re using Standard edition here. You can choose enterprise edition.
Wait for the prerequisite check to complete. If there are any problems either fix them, or check the "Ignore All" checkbox and click the "Next" button.
If you are happy with the summary information, click the "Finish" button.
Wait while the installation takes place.
Once the software installation is complete the Database Configuration Assistant (DBCA) will start automatically.

Once the Database Configuration Assistant (DBCA) has finished, click the "OK" button.
When prompted, run the configuration scripts on each node. When the scripts have been run on each node, click the "OK" button.
The RAC database creation is now complete.
Check the Status of the RAC
There are several ways to check the status of the RAC. The srvctl utility shows the current configuration and status of the RAC database.
If you have configured Enterprise Manager, it can be used to view the configuration and current status of the database using a URL like "https://rac1.localdomain:1158/em".
You can use the following tns settings for the client:
rac =
   (ADDRESS = (PROTOCOL = TCP)(HOST = = 1521))
   (ADDRESS = (PROTOCOL = TCP)(HOST = = 1521))
   (LOAD_BALANCE = yes)
     (SERVICE_NAME = rac)


  1. Hi,

    Can you please add blog on how to add node on Oracle 11gR2 RAC on Windows 2008 R2 using VMWARE.

  2. Hi Mohd,
    To add a node is pretty much straight foward:
    1. Check nodeapp setup is complete with cluvfy
    cluvfy stage -pre nodeadd -n rac5

    2. Run addNode.bat in $CRS_HOME/oui/bin from an existing node:
    addNode.bat "CLUSTER_NEW_NODES={rac5}" "CLUSTER_NEW_VIRTUAL_HOSTNAMES={rac5-vip}" -silent

    3. Use
    cluvfy stage -post nodeadd -n rac5
    to verify node addition and that cluster is not divided into two seperate parts.This may give the following error.

    Reasons are explained in metalink note PRVF-4664 PRVF-4657: Found inconsistent name resolution entries for SCAN name [ID 887471.1]In this case it was because the scan ip was listed on host file. This concludes the first phase of adding a node. Next is to add the oracle home to the new node.

    4. To extend the ORACLE_HOME (RAC) run addNode.bat from $ORACLE_HOME/oui/bin:
    addNode.bat -silent "CLUSTER_NEW_NODES={rac5}"

    5. Use DBCA to add a instance to the new node via instance management.

    6. Check addition of the new node with cluvfy:

    cluvfy comp admprv -o db_config -d $ORACLE_HOME -n rac4,rac5

  3. hi,
    I am stucking with installing GI on winodows 2008 r2 nodes VM. Install is failing at "configuring grid infrastructure". From logs i can see GI configuratiin is completing successfully in first node. However on remote node, oracleobject service is failing to start. Also i can see when this issue happens, diskpart on remote node hangs. Any inputs?

  5. Hi Mohamed,
    Have you disabled firewall and Windows Media Sensing for TCP/IP?
    Is disk.locking set to "FALSE"?
    What's the diskgroup status for second node?

  6. Also do you have any antivirus software installed?
    Last, when you create the share disks, did you choose "Allocate all disk space now"

  7. Hi Mohamed,
    I have an error "ins-40725 unable to determine the existence of an interface with a subnet matching the scan subnet"
    but I set the IP same you.
    please help me !!

    1. hi Kevin ,
      i have same problem have u got solution to it???

  8. Thank you!!!! The VMX configuration info is solid gold!

  9. Hi it is good doc , but do you implement RAC 11gr 2 using OCFS

  10. Hi shafique,
    No, for this install i didn't use OCFS, but it's pretty much same concept. You just need to make sure the shared disks are accessible by both nodes.

  11. Hi This is a really good doc! But how should I use this RAC in my application server. This app is in vm too and stays on the same host with the rac1, rac2 vm. Should I add some ip and host info in the C:\Windows\System32\drivers\etc\hosts file?

    1. Hi Desmond,
      If you are asking how to connect to an oracle database, you'll need to edit the tnsnames.ora to add the entry.
      Our example here is:
      rac =
      (ADDRESS = (PROTOCOL = TCP)(HOST = = 1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = = 1521))
      (LOAD_BALANCE = yes)
      (SERVICE_NAME = rac)

    2. Hi! Thanks for your reply! I think this is the method to connect to rac database throuhg oracle client. I was trying to connect to the rac database from my app. I think I should configure the app server's network. Make it able to access the 192.168.96.* ip.
