Oracle 10gR2 RAC Installation in Linux 5, RHEL5 using VMware Server2

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 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.

vmware_server_installation

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)

 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

At end of root.sh on the last node vipca will fail to run with the following error:

Oracle CRS stack installed and running under init(1M)
Running vipca(silent) for configuring nodeapps
/home/oracle/crs/oracle/product/10/crs/jdk/jre//bin/java: error while loading
shared libraries: libpthread.so.0: cannot open shared object file:
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

click the retry button

[root@rac1 bin]# ./crsctl check crs

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.
