As we know, if you want to setup Oracle Server – especially for testing purpose – it would be better to setup it on your “virtual PC”, not on PC directly. For this purpose, you can use software named “VMware” to achieve this aim. In this document, firstly we discuss how we can use VMware, how we can setup it, create a new “Virtual PC”. On the next articles, we’ll discuss how to install OS (as an operating system, I’m using Centos) on this virtual machine. CentOS is a freely-available operating system that is based on Red Hat Enterprise Linux system. Then we’ll try to setup Oracle Server (10g Release 2) on this virtual machine
In this article, let’s show how we can setup and create new VMware Virtual machine and prepare it for further OS installation
1. First of all, enter to the official site of VMware and download VMware Workstation with a 30-day free evaluation from this address:
https://www.vmware.com/tryvmware/?p=workstation-w
Currently I’m using version 6.0.0 and all these examples are compatible and tested with this version
2. After downloading VMware workstation, install it on your PC
3. Setup will open Welcome Screen
Click on Next button and choose Typical option
4. By clicking “Next” buttons, to begin the installation, click on Install button at the end
5. This will install VMware Workstation software on your PC, After installation complete, click on Finish button. Then restart your PC. Then open this software
6. In this step we try to create new “virtual machine”. Enter to File menu, then New-> Virtual Machine
Click on Next button, then check Typical option as below
Then click Next button, and check your OS version. In this example, as we’re going to setup Oracle server on CentOS, we’ll check Linux option and from “version” option we’ll check Red Hat Enterprise Linux 4
By clicking Next button, we’ll give a name to our virtual machine, and give directory to create this new virtual machine
Then select Use bridged networking option and click Next.
Then you’ve to define size of hard disk by entering its size. I’ll give 15 GB hard disk space and please check Allocate all disk space now option. Although it will take longer to create new hard disk, you’ll see high performance of your virtual machine when installing new applications and adding new files. If you uncheck this option, new hard disk will be created automatically, but when you install new applications, it will impact your performance, because it will allocate space each time new files added or applications installed
That’s all. Your virtual machine is ready to use
Here, you can delete Sound Adapter, Floppy and USB Controller by entering “Edit virtual machine settings”. If you’re going to setup Oracle Server, please make sure you’ve increased your Memory (RAM) to 1GB
In the next article, we’ll show how to setup CentOS on this newly created virtual machine. It’s very easy, believe me
Installing CentOS on VMware – Step by Step
Posted by Kamran Agayev A. on January 5th, 2009
Today, I’m going to show you, installation of CentOS on a virtual machine
First of all, we’ve to download CentOS. CentOS is a freely-available operating system that is based on Red Hat Enterprise Linux system. You can download the latest release (5) from its website. To download, please refer to download page of CentOS web site
http://isoredirect.centos.org/centos/5/isos/i386/
Select nearest location and begin downloading *.iso files.
After you finish downloading *.iso files, you have to mount it and let your VMware recognize it as a virtual “cd” or “dvd”. For this purpose, I prefer to download one DVD *.iso installation file. Please open VMware, double click on CD-ROM (IDE 1-0) item, select Use ISO image option and click Browse button to select your recently downloaded *.iso installation file of CentOS as shown below
Now you virtually inserted you installation DVD into DVD-ROM. And you’re ready to install your OS virtually.
You should change your Memory to 1024 MB for your further Oracle installation. Double click on Memory item and set it to 1024
Then click Power button to start your virtual pc
When your virtual pc starts, you’ll see welcome screen of installation CentOS
If you’ll not be able to see this screen, then restart your virtual pc and click Esc button for Boot menu. And from this menu, select CD-ROM Drive
Click enter. The installation will tell you to begin testing of your installation cd or dvd. Select Skip button. It will skip testing your cd media and save your time
Then you’ll get another welcome screen, you only have to click next button on this screen
Select your language of installation and click Next
Then, select your keyboard configuration to use it for the system you’re installing and click Next
Then, you’ll be warned to create new partitions by erasing ALL DATA on your newly created hard drive. As there’s no information in this drive, you’ll select Yes
In this step, just let it remain selected and click next
Then there’ll be warning “You have chosen to remove all Linux partitions (and ALL DATA on them) on the following drives: /dev/sda Are you sure you want to do this?” Click Yes
Then, you’ll see Network Configurations screen, as it is your test virtual pc, don’t change anything and click next. You can change whatever you want after installation, for now, let it continue in this way and click Next
From this screen, select your region and click Next
Then, you’ll be prompted to enter password for root user, enter it and click Next
To install packages, especially for working with Oracle Server, select all options except Clustering and Storage Clustering. Then select Customize now option and click Next
Then, from Base System menu, select Legacy Software Support, System Tools and click Next
Now, you’re ready for installation. Click next on this screen, the installation will begin
You’ll see how all packages are installing. After a while, your OS will be ready for use
After the installation is completed, click Reboot button to reboot your OS
After reboot, you’ll face with another Welcome screen. There’re some steps need to be completed
Click Forward button on the screen.
Here, just disable your Firewall. Its only for test purpose, don’t disable your Firewall on real system! And click forward button
For testing purpose, it would be good to disable SELinux too
Then keeping Kdump disabled, click Forward
If you need, make your Date and Time configuration and click Forward
If you want to create a new user, you can fill these blanks. You can pass this step too by clicking Forward button
Then Click Finish and the system will reboot
After reboot, CentOS will be opened and you’ll be prompted to enter username (root) and password (root’s password)
Your Centos is ready to use! Congratulations.
In the next article, I’m going to show installation of Oracle 10g Release 2 on our Centos OS
Additionally, while using an operating system inside VMware, you recognize that every time you have to enter to its area and then press Ctrl+Alt buttons to leave this area and to return to your system.
To solve this issue, you should install VMware Tools.
As the VMware Tools will be installed from CD-Rom device, you should disconnect your connected CD-Rom device as shown below
Next, Select VM menu on VMware application and select Install VMware Tools menu item.
Then click Install button on this message box to Install VMware Tools
Then enter to My Computer and double click on CD-ROM Drive. You’ll see there two packages.
Now, double click on *.rpm file to setup
After installation complete, copy another *.gz file to anywhere in hard drive. In our example we are coping it to tmp directory inside FileSystem, paste the file into this folder, right click on it and select Extract Here menu item
Then enter to the folder vmware-tools-distrib and double click on vmware-install.pl file and click Run in Terminal button
Then, whenever you’re asked to enter the value, just click enter
But when you’re prompted to enter value for the display size of your X, be careful to enter default value. If you want your Virtual Machine to be little size, enter 2 (800-600)
That’s all! Your VMware Tools installed. Now you can enter to VMware’s area and exit it without clicking Ctrl+Alt
P.S. If you’ll face with “VMware hgfs: HGFS is disabled in the host” error, just reboot your system

Step by Step installing Oracle 10g RAC on VMware
Posted by Kamran Agayev A. on April 5th, 2011
In this guide I’m going to show you the process of creating Oracle 10g R2 RAC on OEL4. First of all I have to mention that I’ve prepared this guide based on the well known RAC on VMWare guide of for Vincent Chan which can be found at OTN. After using that guide I’ve decided to create a more screenshot based explained guide and prepared this blog post which contains 150 screenshots!
These days wordpress.com is working veeeeery slowly, so it took me two days to upload all images and create this blog post That was really boring. But now the blog post is online and I would be glad to hear the visitors valuable feedbacks.
In this tutorial, we use OEL4 because Oracle 10gR2 is not compatible with OEL5 (as the db was released before the OS released) As in my all tutorials, I use vmware virtual machine. In this guide I will create two virtual machines. Let’s start creating the first machine. But before it, create three directories inside one folder (for example c:\vmware)
[code]C:\vmware\rac1
C:\vmware\rac2
C:\vmware\sharedstorage[/code]
Create the following virtual machine in the first folder and create all shared storages in the third folder
Click Next
Select Typical and click Next
Select “Red Hat Enterprise Linux 4” and Click Next
Provide the name of the virtual machine (rac1), select the location for vmware disk (you can make it c:\vmware\rac1) and click Next
Select bridged network and click next
Define the size of the hard drive of the virtual machine and click Next (set it to 20 GB and don’t check “Allocate all disk space now” checkbox)
Mount the ISO image of the OEL4 installation and start adding more four hard drives and one Ethernet device. Click on Add button
Select “Hard Disk” and click Next
Select “Create a new virtual disk” and click Next
Select “SCSI” and check “Independent->Persistent” and click Next
For the first device, specify the disk size as “3gb”, check “Allocate all disk space now” and click Next
Create a separate folder named “C:\vmware\sharedstorage” in your hard drive, set the name of the new hard drive to “ocfs2disk.vmdk”.
After creating the first device, create more three devices with 4GB in size (asmdisk1.vmdk, asmdisk2.vmdk, asmdisk3.vmdk) and make all of them “Independent->Persistent” and don’t allocate the disk space for each of them
Next, start changing the device node for each of them. Start from the firstly added hard drive, select it, click on Advanced button and make it SCSI 1:0. For next hard drive make it 1:1 and so on
Add new Ethernet device
Change the network connection to “Host-only”
Make sure that the last state of your virtual machine looks like as it’s seen above
Then locate the configuration file of the virtual machine and start editing it
Add the lines that are marked in bold to the configuration file to make the devices be shared between to nodes
- By specifying “disk.locking” to FALSE will allow any virtual machine to load a SCSI disk device even it’s in use by an another virtual machine
- Specify “diskLib.dataCacheMaxSize = “0″ to turn off the disk caching for clustered virtual machines.
- By specifying scsi1.sharedBus = “virtual” will give the whole bus the ability to be shared. This prevents the locking of this specific disk
Start the virtual machine
As you have already mounted the ISO image of the OEL4, the above screen appears
Select installation language and click next
Select appropriate keyboard and click next
Select “Server” as the installation type and click Next
Select Disk Druid for disk partitioning method and click Next
Click Yes for all warnings and click Next
Double click in the first drive /dev/sda
Specify ‘/’ as a mount point, make its files system “ext3” and make the End Cylinder 900 (to make the size of the root folder 7Gb). Check “Force to be a primary partition” and click Ok
Select File System Type as “swap” and change End Cylinder to 1170
Create mount point called /u01, make its files system “ext3” and make End Cylinder 2610 and click Ok
Make sure that the last state of your disk partitioning looks like as it’s seen above
Now let’s configure the network devices. Select the first device and click Edit
Uncheck “Configure using DHCP” and provide the following ip address and netmask:
IP Address: 192.168.2.131
Netmask: 255.255.255.0
Select the second device, edit it, uncheck “Configure using DHCP” and provide the following ip address and netmask
IP address: 10.10.10.31
Netmask: 255.255.255.0
Set the hostname as “rac1.test.az” (you can provide any domain name) and set the gateway to 192.168.2.1
Disable Firewall and SELinux and click Next
Select the default language for the system and click Next
Select Time-Zone and Click Next
Provide the password for the root user and click next
Select necessary packages for Oracle installation. Here’s the list of the necessary packages:
X Window System
Gnome Desktop Environment
Editors
Graphical Internet
Server Configuration Tools
Legacy Network (click Details and select “rsh_server” and “telnet-server”)
Development Tools
Legacy Software Development
Administration Tools
System Tools (select all packages that starts with “ocfs2” and “oracleasm”, select “systat” as well)
Click Next to start the installation
After installation completed the machine restarts. Click Next
Agree with license and click Next
Set the date and time and click Next
Set the display and click Next
You don’t need to create a user so click Next
Click Next and finish the installation
Now let’s install vmware tools. For this, disconnect the mounted ISO image, choose “Install VMware Tools” from VM menu
Double click on VMware tools icon and run the .rpm file by double clicking on it
After the window is closed, open new terminal and run vmware-config-tools.pl and finish the installation of vmware tools
To synchronize the time on the virtual machine with the host machine execute “vmware-toolbox” on the terminal window and check the check box
Edit /boot/grub/grub.conf file and add “clock=pit nosmp noapic nolapic” to the line that reads kernel /boot
The “clock=pit” prevents the clock for running to quickly and “nosmp noapic nolapic” prevents the clock from running too slowly. After you make the change, reboot the machine for change to take effect
Now let’s start the prerequisite steps for Oracle installation. For this we’ll create a group, a user and some directories
[code]groupadd oinstall
groupadd dba
mkdir -p /export/home/oracle
mkdir /ocfs
useradd -d /export/home/oracle -g oinstall -G dba oracle
chown oracle:dba /export/home/oracle /u01
passwd oracle[/code]
Change the .bash_profile (and .bashrc) file and add the following lines:
[code]export EDITOR=vi
export ORACLE_SID=devdb1
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1
export ORA_CRS_HOME=$ORACLE_BASE/product/10.2.0/crs_1
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export PATH=$ORACLE_HOME/bin:$ORA_CRS_HOME/bin:/bin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/X11R6/bin
umask 022[/code]
Now switch to oracle user with “su – oracle” command. Make sure all environment variables are set (echo $ORACLE_HOME). After that, create the following directories:
[code]su - oracle
mkdir -p $ORACLE_BASE/admin
mkdir -p $ORACLE_HOME
mkdir -p $ORA_CRS_HOME
mkdir -p /u01/oradata/devdb[/code]
Note that if environment variables are not set correctly, then the above mentioned directories will not be created.
Change /etc/security/limits.conf file with a root user and add following lines:
[code]oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536[/code]
Change /etc/pam.d/login file and add the following line:
[code]session required /lib/security/pam_limits.so[/code]
Now mount the third installation cd of the OEL4, connect it and open new terminal. Switch to the RPMS folder inside the cd and install “libaio-0.3.105-2.i386.rpm” and “openmotif21-2.1.30-11.RHEL4.6.i386.rpm” packages
[code]rpm –Uvh libaio-0.3.105-2.i386.rpm
rpm –Uvh openmotif21-2.1.30-11.RHEL4.6.i386.rpm[/code]
Change /etc/sysctl.conf file and add the following lines:
[code]kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 1048576
net.core.rmem_max = 1048576
net.core.wmem_default = 262144
net.core.wmem_max = 262144[/code]
Then execute the following command for change to take effect:
/sbin/sysctl -p
Now let’s configure the network configuration files. For this we need to add IP addresses and hostnames to the /etc/hosts file in each node and test the connection by pinging the hostnames
[code]127.0.0.1 localhost
192.168.2.131 rac1.test.az rac1
192.168.2.31 rac1-vip.test.az rac1-vip
10.10.10.31 rac1-priv.test.az rac1-priv
192.168.2.132 rac2.test.az rac2
192.168.2.32 rac2-vip.test.az rac2-vip
10.10.10.32 rac2-priv.test.az rac2-priv[/code]
Try the connection by pinging all hostnames (don’t ping VIP addresses as they will be created during clusterware installation):
ping rac1.test.az
ping rac1-priv.test.az
and son on
Now start creating disk partitions for OCFS2 and ASM. /dev/sdb will be used for OCFS2 and rest devices will be used for ASM.
fdisk /dev/sdb
Type n (to create new partition)
Type p to create a primary partition
Type 1 to provide the partition number
Double click on Enter and type “w” to save the changes
Perform above steps for all hard disk:
fdisk /dev/sdc
fdisk /dev/sdd
fdisk /dev/sde
To map the raw devices to the shared partitions, change /etc/sysconfig/rawdevices file:
[code]/dev/raw/raw1 /dev/sdc1
/dev/raw/raw2 /dev/sdd1
/dev/raw/raw3 /dev/sde1[/code]
And run the following command to make it effective
/sbin/service rawdevices restart
Then change the permission for all newly created raw devices:
[code]chown oracle:dba /dev/raw/raw[1-3]
chmod 660 /dev/raw/raw[1-3]
ls -lat /dev/raw/raw*[/code]
Next, switch to the oracle user and create links for raw devices
[code]su - oracle
ln -sf /dev/raw/raw1 /u01/oradata/devdb/asmdisk1
ln -sf /dev/raw/raw2 /u01/oradata/devdb/asmdisk2
ln -sf /dev/raw/raw3 /u01/oradata/devdb/asmdisk3[/code]
As the raw devices are remapped on boot, change /etc/udev/permissions.d/50-udev.permissions with the root user and add the following lines:
[code]# raw devices
ram*:root:disk:0660
#raw/*:root:disk:0660
raw/*:oracle:dba:0660[/code]
After performing all above steps, shutdown the virtual machine. Then copy all its files to another directory (c:\vmware\rac2)
Open it, switch to the Options tab, change its name to “rac2” and start it
Open Network Configuration and change addresses of each Ethernet device.
eth0 – 192.168.2.132
eth1 – 10.10.10.32
Then from Hardware Device type click on “Probe” button to get new MAC address, enable both network devices, change hostname to rac2.test.az and click Ctrl+S to save the changes. Then add the following line to the /etc/hosts file
127.0.0.1 localhost
Now it’s time to establish user equivalence with SSH. Oracle Universal Installer installs the binaries in one node and then propagates the files to the other nodes. For this, it uses ssh and scp command in the background during installation to run remote commands and copy files to the other cluster nodes. So SSH must be configured so that these commands not prompt for a password. For this power on the first machine, login with root user, switch to the oracle user and generate RSA and DSA key pairs
su – oracle
ssh-keygen –t rsa (click Enter twice)
ssh-keygen –t dsa (click Enter twice)
Perform above steps in the second node (rac2)
Now (from rac1) add the generated keys to the ~/.ssh/authorized_keys file
[code]cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys[/code]
Then from rac1 SSH to rac2 twice and add the .rsa and .dsa keys to the “authorized_keys” file that locates in the first node:
[code]ssh rac2 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
ssh rac2 cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys[/code]
Now copy the “authorized_keys” file from rac1 to rac2:
[code]scp ~/.ssh/authorized_keys rac2:~/.ssh/authorized_keys[/code]
After performing all above steps, you should successfully open SSH connection from rac1 to rac2 and vice verse. So run the following commands in both nodes and ensure that you’re not prompted for the password for the second time:
[code]ssh rac1 date
ssh rac2 date
ssh rac1-priv date
ssh rac2-priv date
ssh rac1.test.az date
ssh rac2.test.az date
ssh rac1-priv.test.az date
ssh rac2-priv.test.az date[/code]
I want to note again “Please make sure that after running above commands on each node, you’re not prompted for the password for the second time”
Now let’s configure Oracle ASM (Automatic Storage Management). So run the following commands from both nodes with root user:
/etc/init.d/oracleasm configure
Pass “oracle” as a parameter for “default user”
Pass “dba” as a parameter for “default group”
Pass “y” for the third and fourth parameters
Then create ASM disks on any node (try on the first node – rac1) with a root user:
/etc/init.d/oracleasm createdisk VOL1 /dev/sdc1
Marking disk “/dev/sdc1″ as an ASM disk: [ OK ]
/etc/init.d/oracleasm createdisk VOL2 /dev/sdd1
Marking disk “/dev/sdd1″ as an ASM disk: [ OK ]
/etc/init.d/oracleasm createdisk VOL3 /dev/sde1
Marking disk “/dev/sde1″ as an ASM disk: [ OK ]
Verify that the ASM disks are visible from every node.
/etc/init.d/oracleasm scandisks
Scanning system for ASM disks: [ OK ]
/etc/init.d/oracleasm listdisks
VOL1
VOL2
VOL3
Now let’s configure Oracle Cluster File System (OCFS2). For this, run “ocfs2console” with a root user from the first node. Then from the Cluster menu select Configure Nodes, click Add button and apply both nodes:
rac1
192.168.2.131
7777
rac2
192.168.2.132
7777
Then propagate the configuration to the second node. For this select “Propagate Configuration” from the Cluster menu.
To configure O2CB to start at the boot unload and configure it on both nodes as a root user:
/etc/init.d/o2cb unload
/etc/init.d/o2cb configure
and pass the following parameters
“y”
ocfs2
61
Now format the file system on the first node (rac1). For this run ocfs2console program, select Format from the Tasks menu and click OK to format the drive. Press Ctrl+Q to quit
Now execute the following command on both nodes to mount the files system
mount -t ocfs2 -o datavolume,nointr /dev/sdb1 /ocfs
and add the following line to the /etc/fstab to mount the files system on boot
/dev/sdb1 /ocfs ocfs2 _netdev,datavolume,nointr 0 0
Create a “clusterware” directory under /ocfs folder and change the owner:
[code]mkdir /ocfs/clusterware
chown -R oracle:dba /ocfs[/code]
Now to test the shared device, create a file in the /ocfs directory from the first node (rac1) and check the same folder in the second node.
cd /ocfs
touch test_file
ls
Now download the clusterware installation, copy it under /tmp directory, unzip it and start the installation
./runInstaller
Provide the folder for the Inventory and click Next
Create a “clusterware” directory under /ocfs folder and change the owner:
[code]mkdir /ocfs/clusterware</span></p><p class="MsoNormal" style="margin: 0 0 10pt;"><span style="font-family: Calibri; font-size: small;">chown -R oracle:dba /ocfs[/code]
Now to test the shared device, create a file in the /ocfs directory from the first node (rac1) and check the same folder in the second node.
cd /ocfs
touch test_file
ls
Now download the clusterware installation, copy it under /tmp directory, unzip it and start the installation
./runInstaller
Provide the folder for the Inventory and click Next
Change the CRS folder to /u01/app/oracle/product/10.2.0/crs_1 and click Next
After checking all prerequisites it should not give any warning, so click Next
Click on Add button and provide the information on the second node:
Public Node Name: rac2.test.az
Private Node Name: rac2-priv.test.az
Virtual Host Name : rac2-vip.test.az
Click on Edit button, change the Interface type of the first Ethernet device (eth0) to “Public” and the second to “Private”
Select External Redundancy and provide the location for OCR :
/ocfs/clusterware/ocr
Select External Redundancy and provide the location for Voting Disk
/ocfs/clusterware/votingdisk
Now click Install button to start the clusterware installation
After installation completes, run both scripts on both nodes
Run /u01/app/oracle/oraInventory/orainstRoot.sh on rac1 and rac2 (wait each script to complete before running it on the second node)
Run /u01/app/oracle/product/10.2.0/crs_1/root.sh on rac1 and rac2 (wait each script to complete before running it on the second node)
After running the second script on the second node (rac2) you’ll get an error (on running VIPCA), so you need to run it manually. Switch to the following directory
cd /u01/app/oracle/product/10.2.0/crs_1/bin
and run the ./vipca to create and configure VIP
Select the first Ethernet device and Click Next
After running the second script on the second node (rac2) you’ll get an error (on running VIPCA), so you need to run it manually. Switch to the following directory
cd /u01/app/oracle/product/10.2.0/crs_1/bin
and run the ./vipca to create and configure VIP
Select the first Ethernet device and Click Next
Type “rac1-vip” on the IP Alias Name for the first node (rac1). The rest boxes will be filled automatically. Click Next
Click Finish to start the installation
After vipca finished successfully, switch to the first node and click OK button on the “script running” window.
Click Exit button to exit the installation of an Oracle Clusterware
Now copy the installation of the database (Oracle 10gR2) to the /tmp directory, unzip and start the installation. You need to start the installation with an oracle user, so run “xhost +” from the root user to allow the connection to the X server and switch to the oracle user
xhost +
su – oracle
./runInstaller
Select “Enterprise Edition” and click Next
Provide the installation directory (/u01/app/oracle/product/10.2.0/db_1)
Select both nodes and click Next
The prerequisite check should be successful, so click Next
Let’s install just a software, so check “Install database Software only” and click Next
Click Install to start the installation
Execute the mentioned script on both nodes (wait for the script to finish before running it on the second node)
After installation finishes, run “dbca” (Database Configuration Assistant), select “Oracle Real Application Clusters database” and click Next
Select “Configure Automatic Storage Management” and click Next
Select both nodes and click Next
Provide the password for an ASM instance, select “Create initialization parameter file (IFILE)” and click Next
Click OK to create and ASM instance on both nodes
Click YES to create listener on both nodes
Now let’s create an ASM disks. For this, click “Create New” button
Provide the name of the diskgroup “dg1”, select the “External” redundancy, select two disks “raw1,raw2” and click OK
The disk group will not be mounted in the second node, so omit this warning. The second node should be restarted (but not now)
Create the second disk group for flash recovery area (fg), select an “External” redundancy, select the last device (raw3) and click Ok
As you see, the state of disk group shows that it’s not mounted on the second node. For this, we need to restart the second node. Click on Finish and restart the second node. After it starts, login with root user and call dbca from the first node again.
Move to the above window again and you’ll see that the disk group is mounted on both nodes. Click on Finish button
Run dbca again and select “Create a Database”
Select both nodes and click Next
Select “General Purpose” and click Next
Provide the database name “devdb” and click Next
Uncheck “Configure the Database with Enterprise Manager” as it’s taking too much (some hours) to finish (however, if you have enough RAM, you can check it) and click Next
Provide the password for the SYS user and click Next
Select “Automatic Storage Management” and click Next
Provide the password for ASM and click OK
Select the first disk group and click Next
Select “Use Oracle-Managed Files” and click Next
Check “Specify Flash Recovery Area” and chose “FG” disk group and click Next
Click Next (We’ll create TAF afterwards)
Click Finish to start the installation
After some hours (as I was running each virtual machine with 1GB RAM) this screen appears. Click Exit
Now both instances will be started.
After all, check the status of the Clusterware. As you see, some applications are with “OFFLINE” state. To make them online, stop and start them with SRVCTL utility as it’s shown above
After all, check the CRS status again. As you see, the State column of all applications are ONLINE
Now connect to the database from the first node (rac1) and run the following query
SQL>col host_name format a20
SQL>SELECT instance_name, host_name, thread#, status from gv$instance;
Try the conection to both instances:
[code]

Now let’s create a Service. Services are used to manage the workload in an RAC environment and provide high availability. To create the service run “dbca”
Select the first option and click Next
Select “Service Management” and click Next
Select the first database and click Next
Provide the name of the Service and click Next
When you specify PREFERRED instances, you are specifying the number of instances on which a service will normally run. The Oracle Clusterware attempts to ensure that the service always runs on the number of nodes for which you have configured the service. Afterwards, due to either instance failure or planned service relocations, a service may be running on an AVAILABLE instance
Select Preferred for the first instance, and Available for the second instance, change the TAF policy to Basic and click Finish
After the Service created automatically, check tnsnames.ora file and you’ll see that the new entry is added

Try to connect to the database using this service. As you see, we’ll automatically connect to the first instance. Now let’s check the RAC high availability
For this, while connecting to the first instance (devdb1) using a “service”, open new terminal, connect to the first instance and shut it down
Now go back to the first session and query the v$instance view again. As you see, you’ll be automatically forwarded to the second instance
In this step by step tutorial I’ve shown you the deep step by step guide using 150 screenshots to make the RAC installation easier for you. I hope you’ll successfully install RAC and make your own tests. Good Luck!

[...] In this guide I’m going to show you the process of creating Oracle 10g R2 RAC on OEL4. First of all I have to mention that I've prepared this guide based on the well known RAC on VMWare guide of for Vincent Chan which can be found at OTN. After using that guide I've decided to create a more screenshot based explained guide and prepared this blog post which contains 150 screenshots!

21. Kamran Agayev A. Says: April 14th, 2011 at 6:55 pm
Dear ISS
Have you done all steps as it’s shown in the screenshots? The first ethernet device should be “Bridged” and the second should be “Host only”
moreover, you need to start them both

30. Jerry Says: May 10th, 2011 at 6:05 pm
All good until I get to the ASM and OCFS2 setup section.
Neither oracleasm nor ocfs2console exist in the OEL4 VM. Is there an installation section missing or have I missed a step?
31. Kamran Agayev A. Says: May 10th, 2011 at 11:14 pm

Dear Babu
Yes you can, but you need to perform some prerequisites as OEL 4 is not supported with Oracle 10gR2 RAC

48. Kamran Agayev A. Says: June 17th, 2011 at 12:56 am
Dear Deepika
There may be some differences in configuration file of the vmware due to the version difference. And the installation RAC on OEL 5 has some pre-requisites (as it is not certified), so would suggest you to get the correct vmware and OEL (you can download OEL 4 from this link – http://edelivery.oracle.com/linux)

Great documentation on how to set up Oracle on VMware! A great tool to view all of the layers of virtual environment to see how your databases are performing in VM is IgniteVM. You can download a free trial of IgniteVM at http://www.confio.com. IgniteVM will show your Tops Sqls/Waits along with Database Health Metrics, the VM/OS guest layer, Host layer and Storage layer in one screen to help you quickly identify bottlenecks at any of the layers.

Hi KamranFirst of all, congratulations for the great article. Very good information. But I have a question. Hope you can help on that.
I have followed all the steps, and I’m able to mount the ocfs share in both nodes, but I’m not able to see files that a create in such nodes. I mean, the file that I create from rac1, can’t be seen in rac2. Please, let me know if you have any idea about what is the problem that I’m facing.
I used the following command to mountmount -t ocfs2 -o datavolume,nointr /dev/sdb1 /ocfs
and also added instructions in /etc/fstab
but when testingcd /ocfstouch test_file
I can’t see file in node 2. If I created from node 2, I can’t see in node 1.
Thanks,Vantuir
73. Vantuir Teixeira Says: July 30th, 2011 at 1:17 am
Kamran,I have dropped and node 2 and recreated everything from the scratch. After that, I configured OCFS share again, and it could be seen by both nodes correctly.Thanks for the article. Very good one.
My only suggestion is to add some lessons learned and common problems that you faced in a new session.
Thanks,Vantuir

HI Kamran,
Firstly Wishing you a lot of happiness in your life.Feeling freshness to reach on your blog today.
Kamran I have configured 2 node RAC on VMware SERVER 2.0.2 .Host Configuration : INTEL Dual Core 1.80 Ghz Processor & 3 GB RAM
Both Guest Machines boot up fine. But as I open one DB instance then execution & I/O performance is slow.But performance is extremely poor after opening 2nd DB instance.CPU usage by oracle on Guest Machine is around 10-30 %.
Guest Machines do not swap & RAM usage on each guest is not more than 700MB. RAM usage decreases with time.
But after all I am unable to understand WHY performance is so bad.
As I think Resource Usage by VMWARE is not more than 50% but after that its performing very slow.Can you share your views to Diagnose & Resolve the performance problem ???
Thanks,Naveen Sheokand

Thank you for posting this nice blog, while configuring hardware , regarding the ethernet adapters, while I’m chosing the option to specify ethernet adapters details, Can I make use of the existing network adapters within the laptop or should I be using a new ethernet adapter installing it into laptop first and then my VM will be able to chose from it? . At present when I try to add the network adpaters section, I’ve only one option i.e Physical network and nothing related to ethernet adapters…please specify some details about this.

Hi kamran,
i am successfully login to rac1 node,but when i am trying to login another node rac2 it’s getting like this error :Cannot open the disk ‘D:\sharedstorage\ocfs2disk.vmdk’ or one of the snapshot disks it depends on.Reason: Failed to lock the file.
please help me to solve this problem
127. Srinias Says: June 6th, 2012 at 12:53 pm
Hello Sir,
“Open it, switch to the Options tab, change its name to “rac2” and start it” in this Rac installation step, i have rename to Rac2 but it will replace rac1 to rac2. It will not create one more virtual disk means. only one will appear i.e rac2. how to create both rac1 and rac2 from your point of view. Pls explain sir.
Thanking you.
128. Kamran Agayev A. Says: June 6th, 2012 at 12:56 pm
You need to stop the rac1 server, copy the folder and then rename the second machine to rac2 and open it
129. Srinias Says: June 6th, 2012 at 2:07 pm
Hello sir,
Here i’m stop the rac1 then copy all the files to rac2 folder. Then went to the vmware and options tab its rename to rac2 and opened. But its replace the rac1 to rac2 server. Not created the both servers means rac1 and rac2. I hope ur understand the situation pls explain clearly sir. How to get rac1 and rac2 servers.
Thanking you.

Hi Kamran
Good morning
I read your blog its really helpful. Today I am going to setup RAC on my 8gb RAM machine. As you said in the begining that OEL 5 is not supportive. So,I am going to download OEL4. Can you confirm any specific update with OEL 4.
I see on edelivery website: OEL 4 Update 4, 5 , 6,7 and 8. Do I need to be specific with Update?
Your response will be highly appreciated.
Thanks
132. muneer Says: July 27th, 2012 at 7:09 pm
Dear Kamran,
Thanks for the excellent post.
I have one doubt though. We created three ASM disks named VOL1, VOL2, VOL3. However, in later installation, they were never used and we had to specify the name of the raw disk partitions instead. Where then the VOL1, VOL2 and VOL3 ASM disks are being used which we created ?
Thanks.

Hi Kamran,
I followed your online step by step rac installation guide to install rac 10g on my pc. after configuration of one vm machine (RAC1) , i copied all the files from rac1 location to rac2 location.When i open the rac2 virtual machine it is opened, but my rac1 machine is not available. As of now only one virtual machine is confiugered, If i want to configure rac2 along with
rac1 vm machines please suggest me how to configure both need to appear on my vmware player.
Thanks and regards,Narendra

Hi Kamran,
Nice blog!
I am new to virtualization and we are currently implementing it.
We have an Oracle 10g on RHEL 4. Oracle is configured on RAC with ASM. The datafiles are stored on an EMC storage.
Our problem is that, when we tried to clone the Database (RAC) servers, we can’t completely copy all the volumes / files from the EMC. Thus, we can’t bring up the virtualize copy of the database.
Any advice you can give in this regard?
147. Kamran Agayev A. Says: January 9th, 2013 at 11:23 am
Hi GaryWhat do you mean “we can’t completely copy”? Do you get any error?
148. ajay Says: January 10th, 2013 at 8:24 am
Hi Kamran,Thank you so much for all your efforts, I followed all the steps mentioned by you, but when I run “ocfs2console” as a root user from first node, and click on the cluster menu and select configure nodes, an error is thrown. Also when I start the rac1 or rac2 I get a message that clustering is not supported. I am using VMware 7 version for creating the VM and OEL5. Also the bridge networking is not working. Your suggestions are highly appreciated. Thank you
149. Gary Says: January 11th, 2013 at 6:06 am
Hi Kamran,
We are using VMWARE 5.1 to clone the physical servers having an Oracle RAC (with ASM). Oracle version is 10.2.0.4.0 using RHEL 4.5. The datafiles are on an EMC storage. Basically, we want to migrate from a physical to a virtual environment.
We did not get any error after running the VMWARE to clone the two RAC servers. However, looking at the cloned RAC servers, they don’t have some of the volumes of the EMC particularly those that was supposed to be used by the Oracle datafiles. Thus, when we can’t bring up the Oracle database, it is looking for the EMC path where the data are stored.
One server that also have an Oracle database (same Oracle and RHEL versions) but is not on RAC and no ASM was successfully cloned and put into service.
We are looking at re-installing the whole thing (basically, following what’s on this blog) on the virtual environment but if you have some inputs on how we can clone the physical servers, I’ll really appreciate it.

Hi Kamran,
Firstly Thanks alot for porviding wonderful info. and even i am getting new things over core dba concepts like clustering and asm with rac.
I followed your rac installation document as u have mentioned. But when i started dbca to configure asm in rac1 it is unable to start asm instance on node2 instead of starting asm2 instance on node2it is showing following errors:
PRKS-1009 Failed to start ASM instance “+ASM2″ on node rac2[PRKS-1011 Failed to check the status of ASM instance "+ASM2" on node rac2 [CRS-0210: colud not find resource ora.rac2.ASM2.asm.]
but it is starting the asm instance on node1 and pfile (init+ASM2.ora) is also created in node2
can i omit the step and continue to go head or else do i need to check the cluster verficationwhat i need to do I strucked up with this problem
Kindly do the need ful
Thanks & RegardsSunny

You have to make sure that ASM on the second node is up. Check necessary log files

Hi Kamran,
I have tried to setup rac using your tutorial. I always get stuck at this point:
“As you see, the state of disk group shows that it’s not mounted on the second node. For this, we need to restart the second node. Click on Finish and restart the second node. After it starts, login with root user and call dbca from the first node again.”
I checked all the services on both nodes and they are online. After restarting the second node, i run the dbca command from oracle user and still the diskgroup is not mounted on second node. Please let me know what might be the error? I havent lost the hope and still wanna try to finish this tutorial.
Eagerly waiting for the reply.
Best Regards,
