2) Open a Terminalsession:

3) Select the IP address (for this example we will use: 192.168.187.128) provided by thehost from the eth0 interface:

4) Using the IP address from the eth0 interface (for this example: 192.168.187.128)connect thru a putty or ssh session as follow (Login:root / Password: oracle):

5) Verify the RAM, swap & tmp in the system, the minimum required RAM is 1.5 GB forOracle Grid Infrastructure for a cluster, or 2.5 GB for Grid Infrastructure for a cluster andOracle Server RAC. The minimum required swap space is 1.5 GB. Oracle recommendsthat you set swap space to 1.5 times the amount of RAM for systems with 2 GB of RAMor less. For systems with 2 GB to 16 GB RAM, use swap space equal to RAM. Forsystems with more than 16 GB RAM, use 16 GB of RAM for swap space. Ensure that

you have at least 1 GB of space in /tmp. If this space is not available, then increase thesize, or delete unnecessary files in /tmp.

6) Ensure you have at least 4.5 GB of space for the grid infrastructure for a (Grid home):

7) Create the oracleOS user and oinstall& dbagroups and create base directories

# groupadd -g 1000 oinstall# groupadd -g 1200 dba

# useradd -u 1100 -g oinstall -G dba oracle# mkdir -p /u01/app/11.2.0/grid# mkdir -p /u01/app/oracle# chown -R oracle:oinstall /u01# chmod -R 775 /u01/

8) Install the ASMLIB RPMs:

http://www.oracle.com/technology/software/tech/linux/asmlib

8.1) For this example we are using the next kernel release:

[root@asmteam /]# uname -r2.6.18-164.el5PAE

8.2) So the next 3 RPMs need to be downloaded:

http://www.oracle.com/technology/software/tech/linux/asmlib/rhel5.html

=)> Intel IA32 (x86) Architecture

==)> Library and Tools

a) oracleasm-support-2.1.3-1.el5.i386.rpm

b) oracleasmlib-2.0.4-1.el5.i386.rpm

==)> Drivers for kernel 2.6.18-164.el5

c) oracleasm-2.6.18-164.el5PAE-2.0.5-1.el5.i686.rpm

8.3) They can be installed as described in the next document:

http://www.oracle.com/technology/tech/linux/asmlib/install.html

8.4) Validate oracleasm RPMs were installed:

[root@asmteam asmlibRPMs]# rpm -qa | grep oracleasm-support-2.1.3-1.el5oracleasm-support-2.1.3-1.el5

[root@asmteam asmlibRPMs]# rpm -qa | grep oracleasmlib-2.0.4-1.el5oracleasmlib-2.0.4-1.el5

[root@asmteam asmlibRPMs]# rpm -qa | grep oracleasm-2.6.18-164.el5PAE-2.0.5-1.el5oracleasm-2.6.18-164.el5PAE-2.0.5-1.el5

9) List the disks available for ASM/ASMLIB, for this example we will use 3 SCSI disks of10 GB each:

10) Check if the partitions exist:

# ls -l /dev/sdb1 /dev/sdc1 /dev/sdd1


8/47

11) If the partitions do not exists then create one partition per disk:

12) Setup the Oracle ASMLIB API (Linux only):

13) Create the ASMLIB disks on the 3 SCSI disk partitions:

14) Download the Oracle Database 11g Release 2 Grid Infrastructure (11.2.0.1.0)for Linux x86 fromhttp://www.oracle.com/technology/software/products/database/index.html

=)> linux_11gR2_grid.zip (980,831,749 bytes) (cksum - 3583041487)

15) Download the Oracle Database 11g Release 2 (11.2.0.1.0) for Linux x86 fromhttp://www.oracle.com/technology/software/products/database/index.html

=)> linux_11gR2_database_1of2.zip (1,285,396,902 bytes) (cksum - 2237015228)=)> linux_11gR2_database_2of2.zip (995,359,177 bytes) (cksum - 2649514514)

16) FTP the linux_11gR2_grid.zip, linux_11gR2_database_1of2.zip &linux_11gR2_database_2of2.zip to your Linux box:

16.1) Create a stage directory, for this example I am creating it at/u01 filesystem:

# mkdir /u01/stage

16.2) Then upload the three *.zip files to your Linux box and place the files at yourstaging directory:


13/47

13/47


16.3) Uncompress the three zip files:

[root@asmteam /]# unzip linux_11gR2_grid.zip; unzip linux_11gR2_database_1of2.zip;unzip linux_11gR2_database_2of2.zip

16.4) You will see 2 new directories (grid& database) on the/u01/stage directory:


14/47

14/47


17) Switch to the oracle OS user, setup & set the environment variables in theinitialization file (for this example we are using bash shell (.bash_profile)):

ORACLE_HOME=/u01/app/11.2.0/gridORACLE_SID=+ASMPATH=$ORACLE_HOME/bin:$PATH

export ORACLE_HOMEexport ORACLE_SIDexport PATH

echo $ORACLE_HOMEexport $ORACLE_SIDexport $PATH

18) Install the Oracle Grid Infrastructure 11gR2 from the graphical session as oracleOS user (for this example we will use VNCserver):

18.1) Start a vncserver & set the Password = oracle:


17/47

17/47


18.2) Connect to the vncserver using the IP address associated with the host:

18.3) Execute the OUI (Oracle Universal Installer) as oracle OS user:

$ /u01/stage/grid/runInstaller


18/47

18/47


18.4) Select: Install and Configure Grid Infrastructure for a Standalone Server.

21/47


18.7) Set the desired password for the ASM& ASMSNMPusers through the SpecifyASM Password window:

18.9) Assign the OS groups for the ASM database Administrator, ASM InstanceAdministrator Operator & ASM instance Administrator through the PrivilegedOperating System Groups window, (for this example we will use dbaOS group for the3 ASM groups, but you are always welcome to specify different OS groups to enforcemore security and separate tasks & roles):
