Upgradation and Migration

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.

Pagina 11 di 36

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

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: 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. di sk. l di skLi di skLi di skLi di skLi di skLi

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

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. # shut down - 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:


22/09/2011


Pagina 19 di 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 pi pi pi

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


22/09/2011


Pagina 20 di 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" file on RAC1 and copy it to RAC2 using the following commands. su - or acl e cd ~/ . ssh cat 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 ~/ . ssh cat 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 dat e ssh r ac2 dat e ssh 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 worry about 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

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.

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 nonroutable 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

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 installing database software and create asm for any queries please contact me any time.

#chkconfig iptables off I have also checked out "http://dsstos.blogspot.com/2009/03/linux-oracle-rac-andbonding-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.
