01 –\u00a0Unpack Files<\/p>\n
Unzip the files.

\nunzip linux.x64_11gR2_database_2of2.zip<\/p>\n
02 – Hosts File
\nThe “\/etc\/hosts” file must contain a fully qualified name for the server.
\n<IP-address> <fully-qualified-machine-name> <machine-name>
\nFor example.
\n127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
\n192.168.0.215 ol7.localdomain ol7<\/p>\n
Set the correct hostname in the “\/etc\/hostname” file.
\nol7.localdomain
\nAutomatic Setup
\nIf you plan to use the “oraclerdbmsserver11gR2preinstall”
\npackage to perform all your prerequisite setup, follow the instructions at http:\/\/publicyum.
\noracle.com (http:\/\/publicyum.
\noracle.com) to setup the yum repository for OL, then perform the following command.
\n# yum install oracle-rdbms-server-11gR2-preinstall
\nIt is probably worth doing a full update as well, but this is not strictly speaking necessary.
\n# yum update
\nManual Setup
\nIf you have not used the “oraclerdbmsserver11gR2preinstall”
\npackage to perform all prerequisites, you will need to manually perform the following
\nsetup tasks.
\nAdd or amend the following lines in the “\/etc\/sysctl.conf” file.
\nfs.aio-max-nr = 1048576
\nfs.file-max = 6815744
\nkernel.shmall = 2097152
\nkernel.shmmax = 536870912
\nkernel.shmmni = 4096
\n# semaphores: semmsl, semmns, semopm, semmni
\nkernel.sem = 250 32000 100 128
\nnet.ipv4.ip_local_port_range = 9000 65500
\nnet.core.rmem_default=262144
\nnet.core.rmem_max=4194304
\nnet.core.wmem_default=262144
\nnet.core.wmem_max=1048586
\nRun the following command to change the current kernel parameters.
\n\/sbin\/sysctl -p<\/p>\n
Add the following lines to the “\/etc\/security\/limits.conf” file.
\noracle soft nproc 2047
\noracle hard nproc 16384
\noracle soft nofile 4096
\noracle hard nofile 65536
\noracle soft stack 10240<\/p>\n
Add the following line to the “\/etc\/pam.d\/login” file, if it does not already exist.
\nsession required pam_limits.so

\nAdditional Setup
\nThe following steps must be performed, whether you did the manual or automatic setup.
\nSet the password for the “oracle” user.
\npasswd oracle
\nSet secure Linux to permissive by editing the “\/etc\/selinux\/config” file, making sure the SELINUX flag
\nis set as follows.
\nSELINUX=permissive
\nOnce the change is complete, restart the server or run the following command.
\n# setenforce Permissive<\/p>\n
If you have the Linux firewall enabled, you will need to disable or configure it, as shown here (\/articles\/linux\/oraclelinux6installation#
\nfirewall) or here
\n(\/articles\/linux\/linuxfirewall#
\ninstallation). To disable it, do the following.
\n# systemctl stop firewalld
\n# systemctl disable firewalld
\nCreate the directories in which the Oracle software will be installed.
\nmkdir -p \/u01\/app\/oracle\/product\/11.2.0.4\/db_1
\nchown -R oracle:oinstall \/u01
\nchmod -R 775 \/u01<\/p>\n
Unless you are working from the console, or using SSH tunnelling, login as root and issue the following command.
\nxhost +<machine-name>
\nAdd the following lines at the end of the “\/home\/oracle\/.bash_profile” file.
\n# Oracle Settings
\nTMP=\/tmp; export TMP
\nTMPDIR=$TMP; export TMPDIR
\nORACLE_HOSTNAME=ol7.localdomain; export ORACLE_HOSTNAME
\nORACLE_UNQNAME=DB11G; export ORACLE_UNQNAME

\nCLASSPATH=$ORACLE_HOME\/JRE:$ORACLE_HOME\/jlib:$ORACLE_HOME\/rdbms\/jlib; export CLASSPATH<\/p>\n
Installation
\nLog into the oracle user. If you are using X emulation then set the DISPLAY environmental variable.
\nDISPLAY=<machine-name>:0.0; export DISPLAY<\/p>\n
Start the Oracle Universal Installer (OUI) by issuing the following command in the database directory.
\n.\/runInstaller<\/p>\n
Post Installation
\nEdit the “\/etc\/oratab” file setting the restart flag for each instance to ‘Y’.
