Oracle 10gR2 RAC Installation in RedHat 5 Linux Using VMware.
Important points to install 10gR2 oracle RAC in linux5.
1.LINUX 5(Redhat 5) doesn't have /etc/sysconfig/rawdevices file. so we have to configure it.
2. Edit the /etc/redhat-release version to redhat-4 and and to invoke the runInstaller use the command
$runInstaller -ignoreSysPrereqs. //this will bypass the os check //
3. Next during clusterware installation at the end of root.sh in node 2 end with error message.So we have adjust the parameters in vipca and srvctl files.
4. vipca will fail to run. so we have to adjust some parameters and configure it manually.
rest of things are similar like RAC 11gR1 installation in linux5 using VMware.
please refer the documentation installing oracle 11gR1 RAC in LINUX5 using vmware. if you have any doubts in my installation steps.
step 1: vmware installation
step 2: guest 0S (LINUX 5) INSTALLATION.
step 3: pre installation steps for installing clusterware.
step 4: Install Vmware tools
step 5: creating shared storage.
step 6: clone virtual machine.
step 7: Installing clusterware.
step 8: Installing oracle software.
Step 1.for vmware installation refer below link to install.
Step 2.Guest Operating system installation: Redhat 5 Linux .
note: create tmp and swap with enough space.
Continue through the OEL 5 installation as you would for a normal server. A general pictorial guide to the installation can be found
here. More specifically,
it should be a server installation with a minimum of 2G swap, firewall and SELinux disabled and the following package groups installed:
- GNOME Desktop Environment
- Editors
- Graphical Internet
- Text-based Internet
- Development Libraries
- Development Tools
- Server Configuration Tools
- Administration Tools
- Base
- System Tools
- X Window System
To be consistent with the rest of the article, the following information should be set during the installation:
- hostname: rac1.localdomain
- IP Address eth0: 192.168.1.121 (public address)
- Default Gateway eth0: 192.168.1.102
- IP Address eth1: 192.168.2.131 (private address)
- Default Gateway eth1: none
You are free to change the IP addresses to suit your network, but remember to stay consistent with those adjustments throughout the rest of the article.
Once the basic installation is complete, install the following packages whilst logged in as the root user.
# From Enterprise Linux 5 Disk 1
cd /media/cdrom/Server
rpm -Uvh binutils-2.*
rpm -Uvh elfutils-libelf-0.*

Step 4: Installing VMware tools
Login as the root user on the RAC1 virtual machine, then select the "Install VMware Tools" as shown in below picture.
Once the package is loaded, the CD should unmount automatically. You must then run the "vmware-config-tools.pl" script as the root user.
# vmware-config-tools.pl
Accept all the default settings and pick the screen resolution of your choice. Ignore any warnings or errors. The VMware client tools are now installed. Reboot the server before proceeding. After the reboot, it is possible the monitor will not be recognised. If this is the case don't panic. Follow the instructions provided on the screen and reconfigure the monitor setting, which will allow the XServer to function correctly.
Shut down the RAC1 virtual machine using the following command.
# shutdown -h now
Step 5: CREATE SHARED STORAGE DISKS
creating a shared storage disks
ocr
votingdisk
asm1
asm2
asm3
here is a steps to create a ocr disk of size 1GB. follow the same steps to create voting disk and asm disks.
select add hardware button and then select HARD DISK.
Click browse button to select the shared storage disk.
create a folder shared for storage storage and select shared and type ocr.
select allocate all disk button.
its very important to select Independent persistent
select virtual device mode scsi1
select optimize for performance
and then click finish after than you can see the new added hard disk with size 1 gb and its properties.
Repeat the previous hard disk creation steps 4 more times, using the following values:
- File Name: votingdisk
Virtual Device Node: SCSI 1:1
Mode: Independent and Persistent
- File Name: asm1
Virtual Device Node: SCSI 1:2
Mode: Independent and Persistent
- File Name: asm2
Virtual Device Node: SCSI 1:3
Mode: Independent and Persistent
- File Name: asm3
Virtual Device Node: SCSI 1:4
Mode: Independent and Persistent
At the end of this process, the virtual machine should look something like the picture below.
Edit the contents of the "/u01/VM/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"
diskLib.maxUnsyncedWrites = "0"
scsi1.present = "TRUE"
scsi1.virtualDev = "lsilogic"
scsi1.sharedBus = "VIRTUAL"
scsi1:0.present = "TRUE"
scsi1:0.mode = "independent-persistent"
scsi1:0.fileName = "/u01/VM/shared/ocr.vmdk"
scsi1:0.deviceType = "plainDisk"
scsi1:0.redo = ""
scsi1:1.present = "TRUE"
scsi1:1.mode = "independent-persistent"
scsi1:1.fileName = "/u01/VM/shared/votingdisk.vmdk"
scsi1:1.deviceType = "plainDisk"
scsi1:1.redo = ""
scsi1:2.present = "TRUE"
scsi1:2.mode = "independent-persistent"
scsi1:2.fileName = "/u01/VM/shared/asm1.vmdk"
scsi1:2.deviceType = "plainDisk"
scsi1:2.redo = ""
scsi1:3.present = "TRUE"
scsi1:3.mode = "independent-persistent"
scsi1:3.fileName = "/u01/VM/shared/asm2.vmdk"
scsi1:3.deviceType = "plainDisk"
scsi1:3.redo = ""
scsi1:4.present = "TRUE"
scsi1:4.mode = "independent-persistent"
scsi1:4.fileName = "/u01/VM/shared/asm3.vmdk"
scsi1:4.deviceType = "plainDisk"
scsi1:4.redo = ""
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 as the root user so you can partition the disks. The current disks can be seen by issueing the following commands.
# cd /dev
# ls sd*
sda sda1 sda2 sdb sdc sdd sde sdf
#
Use the "fdisk" command to partition the disks sdb to sdf. The following output shows the expected fdisk output for the sdb disk.
# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.
The number of cylinders for this disk is set to 1305.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

chown oracle:oinstall /dev/raw/raw3
chown oracle:oinstall /dev/raw/raw4

chmod 640 /dev/raw/raw2
chmod 640 /dev/raw/raw3
chmod 640 /dev/raw/raw4
chmod 640 /dev/raw/raw5
Step 6: CLONE THE VIRTUAL MACHINE
The current version of VMware Server does not include an option to clone a virtual machine, but the following steps illustrate how this can be achieved manually.
Shut down the RAC1 virtual machine using the following command.
# shutdown -h now
Copy the RAC1 virtual machine using the following command.
# cp -R RAC1 RAC2
Edit the contents of the "/u01/VM/RAC2/RAC1.vmx" file, making the following change.
displayName = "RAC2"
And then follow the steps as below:
Edit the hostname to rac2.localdomain
#vi /etc/sysconfig/network
and
#hostname rac2.localdomain
#vi /etc/hosts
check the public,private and virtuals ips are correctly configured.
Start the RAC1 virtual machine and restart the RAC2 virtual machine. When both nodes have started, check they can both ping all the public and private IP addresses using the following commands.
login as oracle user
ping -c 3 rac1
ping -c 3 rac1-priv
ping -c 3 rac2
ping -c 3 rac2-priv
Configure SSH on each node in the cluster. Log in as the "oracle" user and perform the following tasks on each node.
su - oracle
mkdir ~/.ssh
chmod 700 ~/.ssh
/usr/bin/ssh-keygen -t rsa # Accept the default settings.
The RSA public key is written to the ~/.ssh/id_rsa.pub file and the private key to the ~/.ssh/id_rsa file.
Log in as the "oracle" user on RAC1, generate an "authorized_keys" file on RAC1 and copy it to RAC2 using the following commands.
su - oracle
cd ~/.ssh
cat id_rsa.pub >> authorized_keys
scp authorized_keys rac2:/home/oracle/.ssh/
Next, log in as the "oracle" user on RAC2 and perform the following commands.
su - oracle
cd ~/.ssh
cat id_rsa.pub >> authorized_keys
scp authorized_keys rac1:/home/oracle/.ssh/
The "authorized_keys" file on both servers now contains the public keys generated on all RAC nodes.
To enable SSH user equivalency on the cluster member nodes issue the following commands on each node.
ssh rac1 date
ssh rac2 date
ssh rac1.localdomain date
ssh rac2.localdomain date
exec /usr/bin/ssh-agent $SHELL
/usr/bin/ssh-add
You should now be able to SSH and SCP between servers without entering passwords.
Before installing the clusterware, check the prerequisites have been met using the "runcluvfy.sh" utility in the clusterware root directory.
while running this you will get unsuccessful message no need to worry about this. ignore this only for vmware setup testing and education purpose, testing time no need to worry.
/home/oracle/clusterware/cluvfy/runcluvfy.sh stage -pre crsinst -n rac1,rac2 -verbose
Step 7: Installing Clusterware Software
Install the Clusterware Software
Start the RAC1 and RAC2 virtual machines, login to RAC1 as the oracle user and start the Oracle installer.
$cd clusterware
To install 10gR2, you must first install the base release, which is 10.2.0.1. As these version of OS are newer, you should use the following command to invoke the installer:
$ runInstaller -ignoreSysPrereqs // This will bypass the OS check //
note: Edit the /etc/redhat-release file replacing the current release information (Red Hat Enterprise Linux Server release 5 ) with the following:
redhat-4
./runInstaller -ignoreSysPrereqs
change the clusterware directory
if you didn't edit the redhat-release file,you will get error here, and it checks for required rpm packages.
add the rac2 host information
change eth0 to public
NEXT ,the ocr disk information, actually i forgot to take the snapshot
select external redundancy and ocr disk location: /dev/raw/raw1
For voting disk
select external redundancy and voting disk location:/dev/raw/raw2
first run /u01/app/oracle/oraInventory/oraInstRoot.sh in RAC1 after completion run it in RAC2
Second run /u01/crs/oracle/product/10.2.0/crs/root.sh in RAC1 after completion run it in RAC2
while running root.sh in RAC2 NODE it ends with warning message. so follow the below steps
[root@rac1 ~]# /u01/app/oracle/oraInventory/orainstRoot.sh

No such file or directory
Also, srvctl will show similar output if workaround below is not implemented.
edit vipca (in the CRS bin directory on all nodes) to undo the setting of LD_ASSUME_KERNEL. After the IF statement around line 123 add an unset command to ensure LD_ASSUME_KERNEL is not set as follows:
if [ "$arch" = "i686" -o "$arch" = "ia64" -o "$arch" = "x86_64" ]
then
LD_ASSUME_KERNEL=2.4.19
export LD_ASSUME_KERNEL
fi
unset LD_ASSUME_KERNEL <<<== Line to be added
Similarly for srvctl (in both the CRS and, when installed, RDBMS and ASM bin directories on all nodes), unset LD_ASSUME_KERNEL by adding one line, around line 168 should look like this:
LD_ASSUME_KERNEL=2.4.19
export LD_ASSUME_KERNEL
unset LD_ASSUME_KERNEL <<<== Line to be added
Remember to re-edit these files on all nodes:
/bin/vipca
/bin/srvctl
/bin/srvctl
/bin/srvctl
after successful editing of files vipca and srvctl files in bin folder of CRS_HOME directory.
run ./vipca to configure virtual ip manually you will get this error.
vipca will fail to run with the following error if the VIP IP's are in a non-routable range [10.x.x.x, 172.(16-31).x.x or 192.168.x.x]:
# vipca
Error 0(Native: listNetInterfaces:[3])
[Error 0(Native: listNetInterfaces:[3])]
(vipca failing on non-routable VIP IP ranges, manually or during root.sh), if you still have the OUI window open, click OK and it will create the "oifcfg" information, then cluvfy will fail due to vipca not completed successfully, skip below in this note and run vipca manually then return to the installer and cluvfy will succeed. Otherwise you may configure the interfaces for RAC manually using the oifcfg command as root, like in the following example (from any node):
click ok button.
it wills gives the error. follow the steps. dont click next button.
login as root user in node RAC2,
/bin # ./oifcfg setif -global eth0/192.168.1.122:public
/bin # ./oifcfg setif -global eth1/192.168.2.132:cluster_interconnect
/bin # ./oifcfg getif
The goal is to get the output of "oifcfg getif" to include both public and cluster_interconnect interfaces, of course you should exchange your own IP addresses and interface name from your environment. To get the proper IPs in your environment run this command:
/bin # ./oifcfg iflist
[root@rac2 bin]# ./oifcfg setif -global eth0/192.168.1.122:public
[root@rac2 bin]# ./oifcfg setif -global eth1/192.168.2.132:cluster_interconnect
[root@rac2 bin]# ./oifcfg getif
eth0 192.168.1.0 global public
eth0 192.168.1.122 global public
eth1 192.168.2.0 global cluster_interconnect
eth1 192.168.2.132 global cluster_interconnect
[root@rac2 bin]# ./oifcfg iflist
eth0 192.168.1.0
eth1 192.168.2.0
[root@rac2 bin]#
And then run vipca.
/bin # ./vipca
click next
click next
enter rac1-vip.localdomain

step 8: Installing oracle software
follow the same steps given in the below link. except invoking runInstaller.
Start the RAC1 and RAC2 virtual machines, login to RAC1 as the oracle user and start the Oracle installer.
To install 10gR2, you must first install the base release, which is 10.2.0.1. As these version of OS are newer, you should use the following command to invoke the installer:
$ runInstaller -ignoreSysPrereqs // This will bypass the OS check //
./runInstaller -ignoreSysPrereqs
On the "Welcome" screen, click the "Next" button.
