Oracle 11gR2 RAC Installation Steps on Linux

Oracle 11g Real Application Cluster Setup Steps

Prepare the cluster nodes for Oracle RAC:

User Accounts:
NOTE: Oracle recommend different users for the installation of the Grid Infrastructure (GI) and the Oracle RDBMS home. The GI will be installed in a separate Oracle base, owned by user 'grid.' After the grid install the GI home will be owned by root, and inaccessible to unauthorized users.

1.  Create OS groups using the command below. Enter these commands as the 'root' user:

#/usr/sbin/groupadd -g 501 oinstall
#/usr/sbin/groupadd -g 502 dba
#/usr/sbin/groupadd -g 503 oper
#/usr/sbin/groupadd -g 504 asmadmin
#/usr/sbin/groupadd -g 506 asmdba
#/usr/sbin/groupadd -g 507 asmoper

2.     Create the users that will own the Oracle software using the commands:

#/usr/sbin/useradd -u 501 -c "Oracle Grid Infrastructure Owner"  -g oinstall -G asmadmin,asmdba,asmoper grid
#/usr/sbin/useradd -u 502 -c "Oracle RDBMS Owner" -g oinstall -G dba,oper,asmdba oracle

3.  Set the password for the oracle account using the following command. Replace password with your own password.

[root@krac1 ~]# passwd grid
Changing password for user grid.
New UNIX password:
BAD PASSWORD: it is based on a dictionary word
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
[root@krac1 ~]#passwd oracle
Changing password for user oracle.
New UNIX password:
BAD PASSWORD: it is based on a dictionary word
Retype new UNIX password:
passwd: all authentication tokens updated successfully.

4.  Repeat Step 1 through Step 3 on each node in your cluster.

Networking:

1.    Determine your cluster name. The cluster name should satisfy the following conditions:The cluster name is globally unique throughout your host domain.  The cluster name is at least 1 character long and less than 15 characters long.  The cluster name must consist of the same character set used for host names: single-byte alphanumeric characters (a to z, A to Z, and 0 to 9) and hyphens (-).
2.  Determine the public host name for each node in the cluster. For the public host name, use the primary host name of each node. In other words, use the name displayed by the hostname command for example: kracnode1.
3.  Determine the public virtual hostname for each node in the cluster. The virtual host name is a public node name that is used to reroute client requests sent to the node if the node is down. Oracle recommends that you provide a name in the format <public hostname>-vip, for example: kracnode1-vip. The virtual hostname must meet the following requirements:
  •  The virtual IP address and the network name must not be currently in use.
  •  The virtual IP address must be on the same subnet as your public IP address. 
  •   The virtual host name for each node should be registered with your DNS.
4.      Determine the private hostname for each node in the cluster. This private hostname does not need to be resolvable through DNS and should be entered in the /etc/hosts file. A common naming convention for the private hostname is <public hostname>-pvt.
  • The private IP should NOT be accessable to servers not participating in the local cluster.  
  • The private network should be on standalone dedicated switch(es). 
  • The private network should NOT be part of a larger overall network topology.
  • The private network should be deployed on Gigabit Ethernet or better. 
  •  It is recommended that redundant NICs are configured with the Linux bonding driver. Active/passive  is the preferred bonding method due to its simplistic configuration.
[root@kracnode2 ~]#  nslookup kracnode1-vip
Server:         192.168.1.100
Address:        192.168.1.100#53

Name:   kracnode1-vip.india.com
Address: 192.168.1.60
[root@kracnode2 ~]#  nslookup kracnode2-vip
Server:         192.168.1.100
Address:        192.168.1.100#53
Name:   kracnode2-vip.india.com
Address: 192.168.1.61

5.   Define a SCAN DNS name for the cluster that resolves to three IP addresses (round-robin). SCAN IPs must NOT be in the /etc/hosts file, the SCAN name must be resolved by DNS. For DNS configuration setup refer blog Step by Step DNS configuration

[root@kracnode2 ~]# nslookup kracnode-scan
Server:         192.168.1.100
Address:        192.168.1.100#53

Name:   kracnode-scan.india.com
Address: 192.168.1.72
Name:   kracnode-scan.india.com
Address: 192.168.1.70
Name:   kracnode-scan.india.com
Address: 192.168.1.71

6.  Even if you are using a DNS, Oracle recommends that you add lines to the /etc/hosts file on each node, specifying the public IP, VIP and private addresses. Configure the /etc/hosts file so that it is similar to the following example:

NOTE: The SCAN IPs MUST NOT be in the /etc/hosts file. This will result in only 1 SCAN IP for the entire cluster. Refer more about Single Client Access Name(SCAN)

192.168.1.61      kracnode2-vip.india.com       kracnode2-vip

7.      If you configured the IP addresses in a DNS server, then, as the root user, change the hosts search order in /etc/nsswitch.conf on all nodes as shown here:

Old:
hosts: files nis dns
New:
hosts: dns files nis

After modifying the nsswitch.conf file, restart the nscd daemon on each node using the following
command:

# /sbin/service nscd restart

Synchronizing the Time on ALL Nodes:

[root@krac1 ~]# ls -lr /etc/ntp.conf
-rw-r--r-- 1 root root 1833 Dec  9  2009 /etc/ntp.conf
[root@krac1 ~]# service ntpd stop
Shutting down ntpd:                                        [  OK  ]
[root@krac1 ~]# mv /etc/ntp.conf /etc/ntp.conf.bkp

Configuring Kernel Parameter:

1.      As the root user add the following kernel parameter settings to /etc/sysctl.conf. If any of the arameters are already in the /etc/sysctl.conf file, the higher of the 2 values should be used.

kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 6553600
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576

NOTE: The latest information on kernel parameter settings for Linux can be found in My Oracle Support ExtNote:169706.1.

2.      Run the following as the root user to allow the new kernel parameters to be put in place:

#/sbin/sysctl -p

3.      Repeat steps 1 and 2 on all cluster nodes.

NOTE: OUI checks the current settings for various kernel parameters to ensure they meet the minimum requirements for deploying Oracle RAC.

4.     Set shell limits for the oracle and grid user:

To improve the performance of the software on Linux systems, you must increase the shell limits for the
oracle user

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

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

5.      Add or edit the following line in the /etc/pam.d/login file, if it does not already exist:

session required pam_limits.so

6.       Make the following changes to the default shell startup file, add the following lines to the /etc/profile file:

if [[ $USER = "oracle" ] || [ $USER = "grid" ]]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
umask 022
fi

For the C shell (csh or tcsh), add the following lines to the /etc/csh.login file:

if ( $USER = "oracle" || $USER = "grid" ) then
limit maxproc 16384
limit descriptors 65536
endif

7.      Repeat this procedure on all other nodes in the cluster.

Creating the directories.

1.      Create the Oracle Inventory Director:

To create the Oracle Inventory directory, enter the following commands as the root user:

# mkdir -p /u01/app/oraInventory
# chown -R grid:oinstall /u01/app/oraInventory
# chmod -R 775 /u01/app/oraInventory

2.      Creating the Oracle Grid Infrastructure Home Directory:

# mkdir -p /u01/11.2.0/grid
# chown -R grid:oinstall /u01/11.2.0/grid
# chmod -R 775 /u01/11.2.0/grid

3.      Creating the Oracle Base Directory

To create the Oracle Base directory, enter the following commands as the root user:

# mkdir -p /u01/app/oracle
# mkdir /u01/app/oracle/cfgtoollogs #needed to ensure that dbca is able to run after the rdbms installation.
# chown -R oracle:oinstall /u01/app/oracle
# chmod -R 775 /u01/app/oracle

4.      Creating the Oracle RDBMS Home Directory

To create the Oracle RDBMS Home directory, enter the following commands as the root user:

# mkdir -p /u01/app/oracle/product/11.2.0/db_1
# chown -R oracle:oinstall /u01/app/oracle/product/11.2.0/db_1
# chmod -R 775 /u01/app/oracle/product/11.2.0/db_1

Check OS Software Requirements

The OUI will check for missing packages during the install and you will have the opportunity to install them at that point during the prechecks. Nevertheless you might want to validate that all required packages have been installed prior to launching the OUI.

NOTE: These Requirements are for 64-bit versions of Oracle Enterprise Linux 5 and RedHat? Enterprise Linux 5. Requirements for other supported platforms can be found in My Oracle Support ExtNote:169706.1.

Prepare the shared storage for Oracle RAC
     This section describes how to prepare the shared storage for Oracle RAC Each node in a cluster requires external shared disks for storing the Oracle Clusterware (Oracle Cluster Registry and voting disk) files, and Oracle Database files. To ensure high availability of Oracle Clusterware files on Oracle ASM.
  • All of the devices in an Automatic Storage Management diskgroup should be the same size and have the same performance characteristics. 
  • A diskgroup should not contain more than one partition on a single physical disk device. Using logical volumes as a device in an Automatic Storage Management diskgroup is not supported with Oracle RAC.
  • The user account with which you perform the installation (typically, 'oracle') must have write permissions to create the files in the path that you specify.
Shared Storage

For this example installation we will be using ASM for Clusterware and Database storage on top of SAN technology. The following Table shows the storage layout for this implementation:
Block Device
ASMlib Name
Size
Comments
/dev/sdb
OCR_VOTE01
1 GB

Partition the Shared Disks:

This section describes how to prepare the shared storage for Oracle RAC.

1.   Once the LUNs have been presented from the SAN to ALL servers in the cluster, partition the LUNs from one node only, run fdisk to create a single whole-disk partition with exactly 1 MB offset on each LUN to be used as ASM Disk

[root@kracnode1 ~]# fdisk /dev/sdc

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.

[root@kracnode1 ~]#

Load the updated block device partition tables by running the following on ALL servers participating in the cluster:

#/sbin/partprobe

Installing and Configuring ASMLib:

The ASMLib is highly recommended for those systems that will be using ASM for shared storage within the cluster due to the performance and manageability benefits that it provides. Perform the following steps to install and configure ASMLib on the cluster nodes:

1.      Download the following packages from the ASMLib OTN page, if you are an Enterprise Linux customer you can obtain the software through the Unbreakable Linux network.

NOTE: The ASMLib kernel driver MUST match the kernel revision number, the kernel revision number of your system can be identified by running the "uname -r" command. Also, be sure to download the set of RPMs which pertain to your platform architecture, in our case this is i686.

oracleasm-2.6.18-194.el5-2.0.5-1.el5.i686.rpm
oracleasmlib-2.0.4-1.el5.i386.rpm
oracleasm-support-2.1.7-1.el5.i386.rpm

2.      Install the RPMs by running the following as the root user.

[root@kracnode1]# rpm -Uvh oracleasm-2.6.18-194.el5-2.0.5-1.el5.i686.rpm \
> oracleasm-support-2.1.7-1.el5.i386.rpm \
> oracleasmlib-2.0.4-1.el5.i386.rpm

   3:oracleasmlib           ########################################### [100%]
[root@kracnode1]#

3.      Configure ASMLib by running the following as the root user:

[root@kracnode1 ~]# /etc/init.d/oracleasm configure
Configuring the Oracle ASM library driver.

This will configure the on-boot properties of the Oracle ASM library
driver.  The following questions will determine whether the driver is
loaded on boot and what permissions it will have.  The current values
will be shown in brackets ('[]').  Hitting <ENTER> without typing an
answer will keep that current value.  Ctrl-C will abort.

Default user to own the driver interface []: grid
Default group to own the driver interface []: asmdba
Start Oracle ASM library driver on boot (y/n) [n]: y
Scan for Oracle ASM disks on boot (y/n) [y]: y
Writing Oracle ASM library driver configuration: done
Initializing the Oracle ASMLib driver:                     [  OK  ]
Scanning the system for Oracle ASMLib disks:               [  OK  ]
[root@kracnode1 ~]#

4.      Repeat steps 2 - 4 on ALL cluster nodes.

Using ASMLib to Mark the Shared Disks as Candidate Disks:

To create ASM disks using ASMLib:

1.      As the root user, use oracleasm to create ASM disks using the following syntax:

# /usr/sbin/oracleasm createdisk disk_name device_partition_name

Example:

[root@kracnode1 ~]# /usr/sbin/oracleasm createdisk OCR_VOTE01 /dev/sdc1
Writing disk header: done
Instantiating disk: done
[root@kracnode1 ~]# /usr/sbin/oracleasm createdisk OCR_VOTE02 /dev/sdd1

[root@kracnode1 ~]# /usr/sbin/oracleasm createdisk ASM_DISK02 /dev/sdg1
Writing disk header: done
Instantiating disk: done
[root@kracnode1 ~]# /usr/sbin/oracleasm createdisk ASM_DISK03 /dev/sdh1
Writing disk header: done
Instantiating disk: done
[root@kracnode1 ~]# /usr/sbin/oracleasm createdisk ASM_DISK04 /dev/sdi1
Writing disk header: done
Instantiating disk: done
[root@kracnode1 ~]#

2.      Repeat step 1 for each disk that will be used by Oracle ASM.

After you have created all the ASM disks for your cluster, use the listdisks command to verify their availability:

[root@kracnode1 ~]# /usr/sbin/oracleasm listdisks
ASM_DISK01
ASM_DISK02
ASM_DISK03
ASM_DISK04
OCR_VOTE01
OCR_VOTE02
OCR_VOTE03

3.   On all the other nodes in the cluster, use the scandisks command as the root user to pickup the newly created ASM disks. You do not need to create the ASM disks on each node, only on one node in the cluster.

[root@kracnode2 ]# /usr/sbin/oracleasm scandisks
