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

e 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.

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 packageswhilst logged in as the root user.

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

select allocate all disk button.

its very important to select Independent persistent

select virtual device mode scsi1

select optimize for performance




14/36

and then click finish after than you can see the new added hard disk

ith size 1 gb and its properties.

Repeat the previous hard disk creation steps 4 more times, using the

following values:

File Name: votingdiskVirtual Device Node: SCSI 1:1

Mode: Independent and Persistent

•

File Name: asm1

Virtual Device Node: SCSI 1:2


•

File Name: asm2



•

File Name: asm3



•

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.

scsi 1: 4. r edo = " "

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# l s 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.

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.

di spl ayName = "RAC2"

And then follow the steps as below:




19/36

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

pi ng - c 3 r ac1pi ng - c 3 r ac1- pr i v

pi ng - c 3 r ac2

pi ng - c 3 r ac2- pr i v

Configure SSH on each node in the cluster. Log in as the "oracle" user

and perform the following tasks on each node.

su - or acl e

mkdi r ~/ . ssh

chmod 700 ~/ . ssh




20/36

/ usr / bi n/ ssh- keygen - t r sa # Accept t he def aul t s

et t i ngs.

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" fileon RAC1 and copy it to RAC2 using the following commands.

su - or acl e

cd ~/ . sshcat i d_r sa. pub >> aut hor i zed_keys

scp aut hori zed_keys r ac2: / home/ oracl e/ . ssh/

Next, log in as the "oracle" user on RAC2 and perform the following

commands.

su - or acl e

cd ~/ . sshcat i d_r sa. pub >> aut hor i zed_keys

scp aut hori zed_keys r ac1: / home/ oracl e/ . 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 r ac1 date

ssh r ac2 datessh r ac1. l ocal domai n dat e

ssh r ac2. l ocal domai n dat e

exec / usr / bi n/ ssh- agent $SHELL

/ usr/ bi n/ 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 worryabout this. ignore this only for vmware setup testing and education

purpose, testing time no need to worry.

/ home/ or acl e/ cl ust er war e/ cl uvf y/ r uncl uvf y. sh st ag

e - pr e crsi nst - n r ac1, r ac2 - ver bose

Step 7: Installing Clusterware Software

I N S T A L L T H E C L U S T E R W AR E S O F T W A R E

Start the RAC1 and RAC2 virtual machines, login to RAC1 as the oracle

user and start the Oracle installer.

$cd clusterware




21/36

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




22/36

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




23/36

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

hile running root.sh in RAC2 NODE it ends with warning message.

so follow the below steps

[root@rac1 ~]# /u01/app/oracle/oraInventory/orainstRoot.sh

Changing permissions of /u01/app/oracle/oraInventory to 770.

Changing groupname of /u01/app/oracle/oraInventory to oinstall.

The execution of the script is complete

[root@rac2 ~]# /u01/app/oracle/oraInventory/orainstRoot.sh

Changing permissions of /u01/app/oracle/oraInventory to 770.

Changing groupname of /u01/app/oracle/oraInventory to oinstall.

The execution of the script is complete

edit vipca (in the CRS bin directory on all nodes) to undo the setting of

then

27/36

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

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.

rest of the things are similar in the given link documentation

Dear rajesh,

Thank you for your fast reply.

Thank you for your help.

Hi friend,

in your machine you can find your .vmx file in the folder where

you created or installed your guest operating systems , in your

machine check 'C:\Virtual Machines\\

ok bye , all the best...

Firstly Thanks Alot.....

After runnig roort.sh on second node(RAC2) follwoing erroroccured.

Failure at final check of oracle CRS stack. 10

From csrd.log:

2011-02-17 06:32:39.966: [ CRSRTI][1128128]0CSS is not ready.

Received status 3 from CSS. Waiting for good status ..

2011-02-17 06:32:41.456: [ COMMCRS][128535440]clsc_connect:

2011-02-17 06:32:41.456: [ CRSRTI][1128128]0CSS is not ready.

2011-02-17 06:32:42.458: [ CRSMAIN][1128128][PANIC]0CRSD

exiting: Could not init the CSS context

2011-02-17 06:32:42.461: [ default][1128128]Terminating clsd

session

So many people are facing this error. I think its due to cloned

VM.

I have stopped

#service iptables stop




34/36

#chkconfig iptables off

I have also checked out

"http://dsstos.blogspot.com/2009/03/linux-oracle-rac-and-

bonding-conundrum.html "

but there is no bonding directory in '/proc/net '

I dont know how to create interface bonding .

This problem may be due to NIC MAC Addresses because second

node creates eth0.bak and eth1.bak automatically .

I hope you will be able to resolve it . Waiting for reply.

Awesome post. I followed each step and successfully installed

Oracle Rac on my system. You have brilliantly explained all the

steps and have also added the necessary screen shots of the

steps that are a great help. I will share this post to all my

friends too. Thanks for making this post.
