Oracle Database 11g Installation in Linux

DB Silent Install of Oracle 11.2.0.3 on RedHat 6.0

 Configure the Kernel:

                                              Before we can install Oracle 11.2.0.3 on our new VM, we need configure the Linux kernel. The following steps modify key settings to allow Oracle to execute:

Edit the /etc/sysctl.conf and add following lines:

# added for Oracle 11.2.0.3

kernel.shmall = 2097152

kernel.shmmax = 1050470400

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

fs.file-max = 6815744

fs.aio-max-nr = 1048576

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

 

Now execute sysctl -p command to apply the new settings:

Edit the /etc/pam.d/login file and add following line:

# added for Oracle 11.2.0.3

session    required     pam_limits.so

Edit the /etc/security/limits.conf file and add following lines:

# added for Oracle 11.2.0.3

oracle    soft  nproc   2047

oracle    hard  nproc   16384

oracle    soft  nofile  1024

oracle    hard  nofile  65536

Check current status of SELinux:

[root@localhost ~]# /usr/sbin/getenforce

Enforcing

If output is Enforcing then change mode to Permissive as follows:

[root@localhost ~]# /usr/sbin/setenforce 0

To make the change permanent, modify the /etc/sysconfig/selinux change value of SELINUX variable todisabled:

Disable the NTP configuration file

[root@ssslinux ~]# cd /etc

[root@ssslinux etc]# mv ntp.conf ntp.conf.bak

Now we have the RedHat 6.0 Linux kernel ready for Oracle 11.2.0.3.

Add the Oracle User.

Next we need to create the Oracle user account, OS groups and mount point.

ogin as root and create the user oracle account and the OS groups:

[root@ssslinux ~]# groupadd dba

[root@ssslinux ~]# groupadd oinstall

[root@ssslinux ~]# groupadd asmdba

[root@ssslinux ~]# groupadd asmadmin

[root@ssslinux ~]# useradd -g oinstall -G dba,asmdba,asmadmin oracle

Now set the password for the oracle user. Since this is development, I suggest we stick with “oracle”

[root@ssslinux ~]# 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.

Now we create a directory into which the oracle software will be installed. We need to set this new directory to be owned by oracle:

[root@ssslinux ~]# mkdir /u01

[root@ssslinux ~]# mkdir /u01/app

[root@ssslinux ~]# chown oracle:dba /u01/app

[root@ssslinux ~]# chmod 777 /u01/app

Now we can log into our new oracle account and configure the bash profile:

[root@ssslinux ~]#  su - oracle

[oracle@ssslinux ~]$  vi ~/.bash_profile

Add the following lines to the profile script:

LD_BIND_NOW=1; export LD_BIND_NOW

TMP=/tmp; export TMP

TMPDIR=$TMP; export TMPDIR

ORACLE_HOSTNAME=`hostname`; export ORACLE_HOSTNAME

ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE

ORACLE_TERM=xterm; export ORACLE_TERM

PATH=/usr/sbin:$PATH; export PATH

LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH

CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH

if [ $USER = "oracle" ]; then

 if [ $SHELL = "/bin/ksh" ]; then

   ulimit -p 16384

   ulimit -n 65536

 else

   ulimit -u 16384 -n 65536

 fi

fi
