An example of this type of Linux installations can be seen here. Alternative installations may require more packages to be loaded, in addition to the ones listed below.
Download Software
Download the Oracle software from OTN or MOS depending on your support status.
- OTN: Oracle Database 11g Release 2 (11.2.0.1) Software (64-bit)
- MOS: Oracle Database 11g Release 2 (11.2.0.2) Software (64-bit)
Unpack Files
Unzip the files.
# 11.2.0.1 unzip linux.x64_11gR2_database_1of2.zip unzip linux.x64_11gR2_database_2of2.zip #11.2.0.2 unzip p10098816_112020_Linux-x86-64_1of7.zip unzip p10098816_112020_Linux-x86-64_2of7.zip
You should now have a single directory called "database" containing installation files.
Hosts File
The "/etc/hosts" file must contain a fully qualified name for the server.
<IP-address> <fully-qualified-machine-name> <machine-name>
For example.
127.0.0.1 localhost.localdomain localhost 192.168.0.181 ol6-112.localdomain ol6-112
Set Kernel Parameters
Oracle recommend the following minimum parameter settings.
fs.suid_dumpable = 1 fs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.shmall = 2097152 kernel.shmmax = 536870912 kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 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 = 1048586
The current values can be tested using the following command.
/sbin/sysctl -a | grep <param-name>
Add or amend the following lines in the "/etc/sysctl.conf" file.
fs.suid_dumpable = 1 fs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.shmall = 2097152 kernel.shmmax = 536870912 kernel.shmmni = 4096 # semaphores: semmsl, semmns, semopm, semmni kernel.sem = 250 32000 100 128 net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default=4194304 net.core.rmem_max=4194304 net.core.wmem_default=262144 net.core.wmem_max=1048586
Run the following command to change the current kernel parameters.
/sbin/sysctl -p
Add the following lines to the "/etc/security/limits.conf" file.
oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536 oracle soft stack 10240
Disable secure linux by editing the "/etc/selinux/config" file, making sure the SELINUX flag is set as follows.
SELINUX=disabled
Once the change is complete, restart the server.
Setup
Install the following packages if they are not already present.# From Oracle Linux 6 DVD cd /media/cdrom/Server/Packages rpm -Uvh binutils-2*x86_64* rpm -Uvh glibc-2*x86_64* nss-softokn-freebl-3*x86_64* rpm -Uvh glibc-2*i686* nss-softokn-freebl-3*i686* rpm -Uvh compat-libstdc++-33*x86_64* rpm -Uvh glibc-common-2*x86_64* rpm -Uvh glibc-devel-2*x86_64* rpm -Uvh glibc-devel-2*i686* rpm -Uvh glibc-headers-2*x86_64* rpm -Uvh elfutils-libelf-0*x86_64* rpm -Uvh elfutils-libelf-devel-0*x86_64* rpm -Uvh gcc-4*x86_64* rpm -Uvh gcc-c++-4*x86_64* rpm -Uvh ksh-*x86_64* rpm -Uvh libaio-0*x86_64* rpm -Uvh libaio-devel-0*x86_64* rpm -Uvh libaio-0*i686* rpm -Uvh libaio-devel-0*i686* rpm -Uvh libgcc-4*x86_64* rpm -Uvh libgcc-4*i686* rpm -Uvh libstdc++-4*x86_64* rpm -Uvh libstdc++-4*i686* rpm -Uvh libstdc++-devel-4*x86_64* rpm -Uvh make-3.81*x86_64* rpm -Uvh numactl-devel-2*x86_64* rpm -Uvh sysstat-9*x86_64* rpm -Uvh compat-libstdc++-33*i686* cd / eject
Note. This will install all the necessary 32-bit packages for 11.2.0.1. From 11.2.0.2 onwards many of these are unnecessary, but having them present does not cause a problem.
Create the new groups and users.
groupadd -g 501 oinstall groupadd -g 502 dba groupadd -g 503 oper groupadd -g 504 asmadmin groupadd -g 506 asmdba groupadd -g 505 asmoper useradd -u 502 -g oinstall -G dba,asmdba,oper oracle passwd oracle
Note. We are not going to use the "asm" groups, since this installation will not use ASM.
Create the directories in which the Oracle software will be installed.
mkdir -p /u01/app/oracle/product/11.2.0/db_1 chown -R oracle:oinstall /u01 chmod -R 775 /u01
Login as root and issue the following command.
xhost +<machine-name>
Login as the oracle user and add the following lines at the end of the ".bash_profile" file.
# Oracle Settings TMP=/tmp; export TMP TMPDIR=$TMP; export TMPDIR ORACLE_HOSTNAME=ol6-112.localdomain; export ORACLE_HOSTNAME ORACLE_UNQNAME=DB11G; export ORACLE_UNQNAME ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1; export ORACLE_HOME ORACLE_SID=DB11G; export ORACLE_SID PATH=/usr/sbin:$PATH; export PATH PATH=$ORACLE_HOME/bin:$PATH; export PATH LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH
Installation
Log into the oracle user. If you are using X emulation then set the DISPLAY environmental variable.
Start the Oracle Universal Installer (OUI) by issuing the following command in the database directory.DISPLAY=<machine-name>:0.0; export DISPLAY
./runInstaller
Proceed with the installation of your choice. The prerequisites checks will fail for the following version-dependent reasons:
- 11.2.0.1: The installer shows multiple "missing package" failures because it does not recognize several of the newer version packages that were installed. These "missing package" failures can be ignored as the packages are present. The failure for the "pdksh" package can be ignored because we installed the "ksh" package in its place.
- 11.2.0.2: The installer should only show a single "missing package" failure for the "pdksh" package. It can be ignored because we installed the "ksh" package in its place.
