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

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:

[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:

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
