10gr2 Rac Installation in Lunx5

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. 11gR1RACInstallationOnOEL5UsingVMwareServer2 10gR2 RAC Installation in RHEL4 using VMware

http://www.oracle-base.com/articles/11g/OracleDB11gR1RACInstallationOnOEL5UsingVMwareServer2.php#vmware_server_installation

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.

3. Pre Installation steps for installing clusterware and oracle software.Oracle Installation PrerequisitesPerform the following steps whilst logged into the RAC1 virtual machine as the root user.

The /etc/hosts file must contain the following information.

127.0.0.1 localhost.localdomain localhost # Public 192.168.1.121 rac1.localdomain rac1 192.168.1.122 rac2.localdomain rac2 #Private 192.168.2.131 rac1-priv.localdomain rac1-priv 192.168.2.132 rac2-priv.localdomain rac2-priv #Virtual 192.168.1.111 rac1-vip.localdomain rac1-vip 192.168.1.112 rac2-vip.localdomain rac2-vip

http://www.oracle-base.com/articles/linux/OracleEnterpriseLinux5Installation.php

Add the following lines to the /etc/sysctl.conf file.

kernel.shmmni = 4096 # semaphores: semmsl, semmns, semopm, semmni kernel.sem = 250 32000 100 128 net.ipv4.ip_local_port_range = 1024 65000 net.core.rmem_default=4194304 net.core.rmem_max=4194304 net.core.wmem_default=262144 net.core.wmem_max=262144

Run the following command to change the current kernel parameters.

/sbin/sysctl -p

Add the following lines to the /etc/security/limits.conf file.

oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536

Add the following lines to the /etc/pam.d/login file, if it does not already exist.

session required pam_limits.so

Disable secure linux by editing the /etc/selinux/config file, making sure the SELINUX flag is set as follows.

SELINUX=disabled

Create the new groups and users.

groupadd oinstall groupadd dba groupadd oper groupadd asmadmin

useradd -u 500 -g oinstall -G dba,oper,asmadmin oracle passwd oracle

Create the directories in which the Oracle software will be installed.

mkdir -p /u01/crs/oracle/product/10.2..0/crs mkdir -p /u01/app/oracle/product/10.2.0/db_1 chown -R oracle:oinstall /u01

Edit the /etc/redhat-release file replacing the current release information (Red Hat Enterprise Linux Server release 5) with the

following:

redhat-4

eg:[root@rac1 ~]# vi /etc/redhat-release redhat-4Login as the oracle user and add the following lines at the end of the .bash_profile file.

# Oracle Settings TMP=/tmp; export TMP TMPDIR=$TMP; export TMPDIR

ORACLE_HOSTNAME=rac1.localdomain; export ORACLE_HOSTNAME ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1; export ORACLE_HOME ORACLE_TERM=xterm; export ORACLE_TERM PATH=/usr/sbin:$PATH; export PATH PATH=$ORACLE_HOME/bin:$PATH; export PATH

LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH

if [ $USER = "oracle" ]; then if [ $SHELL = "/bin/ksh" ]; then ulimit -p 16384 ulimit -n 65536 else ulimit -u 16384 -n 65536 fi fi

The packages listed in this section (or later versions) are required for Oracle Clusterware 10g Release 2 and Oracle RAC 10g Release 2 running on the Oracle Enterprise Linux 5 platform.

32-bit (x86) Installations

* binutils-2.17.50.0.6-2.el5 * compat-libstdc++-296-2.96-138 * compat-libstdc++-33-3.2.3-61 * elfutils-libelf-0.125-3.el5 * elfutils-libelf-devel-0.125 * gcc-4.1.1-52 * gcc-c++-4.1.1-52 * glibc-2.5-12 * glibc-common-2.5-12 * glibc-devel-2.5-12 * glibc-headers-2.5-12

* libaio-0.3.106 * libaio-devel-0.3.106 * libgcc-4.1.1-52 * libstdc++-4.1.1 * libstdc++-devel-4.1.1-52.e15 * libXp-1.0.0-8 * make-3.81-1.1 * openmotif-2.2.3 * sysstat-7.0.0 * unixODBC-2.2.11 * unixODBC-devel-2.2.11

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 disksocr votingdiskasm1asm2asm3

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: votingdiskVirtual Device Node: SCSI 1:1Mode: Independent and Persistent

• File Name: asm1Virtual Device Node: SCSI 1:2Mode: 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 = ""



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/sdbDevice contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabelBuilding a new DOS disklabel. Changes will remain in memory only,until you decide to write them. After that, of course, the previouscontent 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)Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

In each case, the sequence of answers is "n", "p", "1", "Return", "Return", "p" and "w".

Once all the disks are partitioned, the results can be seen by repeating the previous "ls" command.

# cd /dev# ls sd*sda sda1 sda2 sdb sdb1 sdc sdc1 sdd sdd1 sde sde1 sdf sdf1#

/etc/sysconfig/rawdevices file is not available in the Linux 5 OS. SO we have to create a below file.

[root@rac1 ~]# vi /etc/udev/rules.d/63-oracle-raw.rules ACTION=="add", KERNEL=="sdb1", RUN+="/bin/raw /dev/raw/raw1 %N" ACTION=="add", KERNEL=="sdc1", RUN+="/bin/raw /dev/raw/raw2 %N" ACTION=="add", KERNEL=="sdd1", RUN+="/bin/raw /dev/raw/raw3 %N" ACTION=="add", KERNEL=="sde1", RUN+="/bin/raw /dev/raw/raw4 %N" ACTION=="add", KERNEL=="sdf1", RUN+="/bin/raw /dev/raw/raw5 %N" KERNEL=="raw[1]*", OWNER="root", GROUP="oinstall", MODE="640" KERNEL=="raw[2-5]*", OWNER="oracle", GROUP="oinstall", MODE="644"

Step 6: CLONE THE VIRTUAL MACHINEThe 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/networkand #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 rac1ping -c 3 rac1-privping -c 3 rac2ping -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 - oraclemkdir ~/.sshchmod 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 - oraclecd ~/.ssh

cat id_rsa.pub >> authorized_keysscp authorized_keys rac2:/home/oracle/.ssh/

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

su - oraclecd ~/.sshcat id_rsa.pub >> authorized_keysscp 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 datessh rac2 datessh rac1.localdomain datessh rac2.localdomain dateexec /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 SoftwareStart 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 diskselect external redundancy and voting disk location:/dev/raw/raw2

first run /u01/app/oracle/oraInventory/oraInstRoot.sh in RAC1 after completion run it in RAC2Second run /u01/crs/oracle/product/10.2.0/crs/root.sh in RAC1 after completion run it in RAC2while running root.sh in RAC2 NODE it ends with warning message. so

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

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_KERNELfi

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=2.4.19export 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]:# vipcaError 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 getifeth0 192.168.1.0 global publiceth0 192.168.1.122 global publiceth1 192.168.2.0 global cluster_interconnecteth1 192.168.2.132 global cluster_interconnect[root@rac2 bin]# ./oifcfg iflisteth0 192.168.1.0eth1 192.168.2.0[root@rac2 bin]#

And then run vipca./bin # ./vipca

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
