2.2 Creating Groups and User for Oracle

$ /usr/sbin/groupadd -g 501 oinstall

$ /usr/sbin/groupadd -g 502 dba

$ /usr/sbin/groupadd -g 503 oper

$ /usr/sbin/groupadd -g 504 asm

$ /usr/sbin/groupadd -g 505 asmdba

$ /usr/sbin/useradd -m -u 501 -g oinstall -G dba,oper,asm, asmdba -d /home/oracle -s /bin/bash -c

“Oracle Software Owner” oracle

$ /usr/sbin/passwd oracle

2.3 Creating the Oracle Base Directory

$ mkdir -p /u01/app/oracle

$ chown -R oracle:oinstall /u01/app

$ chmod -R 775 /u01/app

2.4 Setting /home/oracle/.bash_profile for the Oracle user

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1

export PATH=/usr/sbin:$PATH

export PATH=$ORACLE_HOME/bin:$PATH

export ORACLE_TERM=xterm

export LD_LIBRARY_PATH=$ORACLE_HOME/lib

export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/lib:/usr/lib:/usr/local/lib

export CLASSPATH=$ORACLE_HOME/JRE

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

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

export TEMP=/tmp

2.5 Setting Shell Limits for the Oracle User

$ cat >> /etc/security/limits.conf <<EOF

oracle soft nproc 2047

oracle hard nproc 16384

oracle soft nofile 1024

oracle hard nofile 65536

EOF

$ cat >> /etc/pam.d/login <<EOF

session    required     /lib/security/pam_limits.so

session    required     pam_limits.so

EOF

3. Installing Oracle Database 11g Release 2

We used “/home/oracle/wkdir/11gr2″.

$ su – oracle

$ mkdir -p /home/oracle/wkdir/11gr2

$ cd /home/oracle/wkdir/11gr2

$ unzip linux_11gR2_database_1of2.zip

$ unzip linux_11gR2_database_2of2.zip

Installing the Oracle Database 11gR2 software procedure step-by step:

$ cd /home/oracle/wkdir/11gr2

$ cd database

$ ./runInstaller
