Installation of Oracle Database 11g on Linux with ASM

Let’s assume that you have already installed Linux on your server. And disks are already bounded to the server.

1. Creating OS groups and users.

#Creating groups for Grid Infrastructure

groupadd asmadmin
groupadd asmdba
groupadd asmoper

#Creating groups for Oracle Software

groupadd oinstall
groupadd dba
groupadd oper

#Creating user for Grid Infrastructure

useradd -g oinstall -G dba,asmadmin,asmdba,asmoper -d /home/grid grid

#Creating user for Oracle Software

useradd -g oinstall -G dba,oper,asmdba -d /home/oracle oracle

#Setting password for users

passwd grid
passwd oracle

2. Creating necessary directories

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

3. Creating .bash_profile-s

#For Oracle user

su – oracle
vi .bash_profile

if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

ORACLE_SID=orcl; export ORACLE_SID

ORACLE_UNQNAME=orcl; export ORACLE_UNQNAME

CLASSPATH=${CLASSPATH}:$ORACLE_HOME/rdbms/jlib
CLASSPATH=${CLASSPATH}:$ORACLE_HOME/network/jlib
export CLASSPATH

THREADS_FLAG=native; export THREADS_FLAG

export TEMP=/tmp
export TMPDIR=/tmp

umask 022

#For Grid user

export TMPDIR=/tmp

umask 022

4. Setting resource limits

Edit the following files:

# /etc/security/limits.conf

[root@orcl ~]# cat >> /etc/security/limits.conf <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
EOF

# /etc/pam.d/login

[root@orcl ~]# cat >> /etc/pam.d/login <session required pam_limits.so
EOF

# /etc/profile

[root@orcl ~]# cat >> /etc/profile <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
EOF

# /etc/csh.login

[root@orcl ~]# cat >> /etc/csh.login <if ( \$USER == “oracle” || \$USER == “grid” )
then
limit maxproc 16384
limit descriptors 65536
endif
EOF

# /etc/hosts

[root@orcl ~]#  vi /etc/hosts

127.0.0.1 localhost.localdomain localhost
