Intel Based Server LINUX
Goal
This document describes the installation of Oracle 10gR2 database on RedHat Enterprise Linux/Oracle Enterprise Linux 5 (x86).
NOTE: RAC customers are strongly advised to also review Note:414163.1
Installation requirements:
1. Hardware Requirements
a) Physical Memory
At least 1024MB of physical RAM is required. To determine the physical RAM size, enter the following command:
# grep MemTotal /proc/meminfo
b) Swap Space
The following table describes the relationship between installed RAM and the configured swap space requirement.
RAM
|
Swap Space
|
Between 1024 MB and 2048 MB
|
1.5 times the size of RAM
|
Between 2049 MB and 8192 MB
|
Equal to the size of RAM
|
More than 8192 MB
|
0.75 times the size of RAM
|
To determine the size of the configured swap space, enter the following command:
# grep SwapTotal /proc/meminfo
c) Disk space Requirement
- 400 MB of disk space in the /tmp directory
- Between 1.5 GB and 3.5 GB of disk space for the Oracle software, depending on the installation type
- 1.2 GB of disk space for a preconfigured database that uses file system storage (optional)
To determine the amount of free disk space on the system, enter the following command:
# df -h
2. Kernel Requirements
a) Version
The system must be running the following kernel version (or a later version)
2.6.18-8
To determine whether the required kernel is installed, enter the following command:
# uname -r
b) SELinux
Due to an internal bugs of Oracle database (Bug 6140224, Bug 6079461), SELinux has to be disabled on RHEL/OEL 5 to work with Oracle database 10.2. Please refer
Note 454196.1 for more information about these bugs.
To check whether SELinux is Enabled or Disabled in a system, please refer to Note 432988.1
To disable SELinux, please refer to Note 457458.1
3. Installing required packages
The following packages are required to be installed to have a supported to installation. It is recommended to choose a "default list of RPMs" during installation as per
Note 376183.1 'Defining a "default RPMs" installation of the RHEL OS'. Please note following points while installing these packages
a) The version numbers for these packages given below are the minimum version required. If you have the packages with higher versions than the versions mentioned below, you can install the higher version packages.
b) Some of the below packages might be already part of "Default RPMs installation", and some of the packages might be already part of "base" installation of OS.
c) Some of the below packages may require other packages as dependencies. So, make sure that you have installed these packages including the dependency packages required.
binutils-2.17.50.0.6-2.el5
compat-libstdc++-33-3.2.3-61
elfutils-libelf-0.125-3.el5
elfutils-libelf-devel-0.125
gcc-4.1.1-52
gcc-c++-4.1.1-52
glibc-2.5-12
glibc-common-2.5-12
glibc-devel-2.5-12
glibc-headers-2.5-12
libaio-0.3.106
libaio-devel-0.3.106
libgcc-4.1.1-52
libstdc++-4.1.1
libstdc++-devel-4.1.1-52.e15
make-3.81-1.1
sysstat-7.0.0
unixODBC-2.2.11
unixODBC-devel-2.2.11
Note: As per documentation
bug 7680459, the package
libXp-1.0.0-8 is also required to invoke OUI successfully.
4.
Set the kernel parameters
Add the following the lines in the file
/etc/sysctl.conf
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 9000 65500
The runInstaller (OUI) checks may expect this to be the old guidance of "1024 65000". The new guidance from Oracle development is "9000 65500". Please allow the runInstaller (OUI) to proceed with the new guidance from Oracle development.
net.core.rmem_default = 262144
net.core.rmem_max = 2097152
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
To place these changes into effect, execute the command:
# sysctl -p
5.
Create Oracle user and groups
# groupadd oinstall
# groupadd dba
# useradd -g oinstall -G dba oracle
# passwd oracle
6.
Create the required directories for Oracle Base and change the ownership
For example:
# mkdir -p /u01/app/oracle
# chown -R oracle:oinstall /u01/app/oracle
7.
Set the session limits for Oracle user
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
Add the following line in the
/etc/pam.d/login file
session required pam_limits.so
Add the following lines to the
/etc/profile.
if [ $USER = "oracle" ]; then
ulimit -u 16384
ulimit -n 65536
fi
8.
Configure the Oracle user's environment
Configuring the oracle User's Environment, using the appropriate section of "Oracle� Database Quick Installation Guide 10g Release 2 (10.2) for Linux x86". Note that setting $ORACLE_BASE (not $ORACLE_HOME) in the environment will ease a couple of entries in the Oracle Universal Installer.
For example, if oracle user is using bash shell, and has the home directory as /home/oracle.
The following lines to be added to /home/oracle/.bash_profile
export ORACLE_BASE=/u01/app/oracle
export ORACLE_SID=orcl
unset ORACLE_HOME
9.
Invoking OUI
Log in as Oracle user and start installation by any one of the following methods. This is required because Oracle 10.2 expects the OS to be RHEL 3 or RHEL/OEL 4.
Method 1:
# ./runInstaller -ignoreSysPrereqs
Method 2:
Follow
Note 456634.1
10. Warning at "Product-Specific Prerequisite Checks" screen
During the installation at the screen "Product-Specific Prerequisite Checks", OUI gives a warning that Oracle database 10g is not certified on the current operating system. If we still proceed to continue, OUI gives a dialog-box with a warning
"Some recommended prerequisite checks have failed. You might get errors during installation. Do you want to proceed?"
This warning can be ignored, if all the above requirements are satisfied.
