APPLIES TO:
Oracle Server - Enterprise Edition - Version 10.2.0.1 and laterOracle Enterprise Linux 4.0
Linux x86
Red Hat Advanced Server
PURPOSE
This note explains the requirements that need to be met for a successful installation of the 10.2.0.X base release on Red Hat Enterprise Linux AS/ES 4.0 Linux x86.
It is NOT the purpose of this NOTE to repeat every "how-to" step that is presented in the 10gR2 Installation Guide manual. For example this NOTE does not include how to create the Linux OS account named "oracle", nor does it cover how to set environment variables. Both are adequate covered in Chapter 2 "Oracle Database Preinstallation Requirements" of the 10gR2 Installation Guide manual.
The 10.2.0.X media is no longer available for download from OTN, but customers can request the media by following the process in Note 1071023.1.
SCOPE
This procedure is meant for those planning/trying to install Oracle Server 10.2.0.X.0 on Redhat 4.0 on the x86 platform. Since it is the expressed goal to keep Oracle Enterprise Linux functionally IDENTICAL to RHEL, this NOTE is also completely applicable to OEL 4 (update 4 or higher).
DETAILS
1. Hardware:
==========
* Minimum Hardware Requirements
- 1024 MB of physical RAM
- 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
- 400 MB of disk space in the /tmp directory.
- Between 1.5 GB to 3.5 GB of disk space depending upon installation
- 1.2 GB of disk space for a preconfigured database that uses file
system storage (optional, but recommended)
2. Software:
=========
* Red Hat Enterprise Linux AS/EL 4
- Kernel 2.6.9-5.EL or higher
* Required OS Components (per Release Notes, and Quick Install Guide)
- This list is based upon a "default-RPMs" installation of RHEL AS/ES 4 general availability (aka update base, aka update 0). Additional RPMs may be needed if a "less-than-default-RPMs" installation of RHEL AS/ES 4 is performed. For more information, please refer to Note 376183.1, "Defining a "default RPMs" installation of the RHEL OS"
The RPM packages can be located in the mentioned CD media/RedHat/RPMs:
binutils-2.15.92.0.2-18
compat-libstdc++-33.2.3-47.3
elfutils-libelf-0.97-5
elfutils-libelf-devel-0.97-5
gcc-3.4.5-2
gcc-c++-3.4.5-2
glibc-2.3.4-2.19
- There is one unusual point to share here. Several unpublished Oracle Bugs have identified that the version of the "glibc" RPM that is provided (by default) with RHEL/OEL 4 update 6 (aka glibc-2.3.4-2.39) has a bug, and should be disallowed if found on the system. Therefore, you will find that the OUI (aka runInstaller) will throw an error if glibc-2.3.4-2.39 is found. Please use any newer version of the "glibc" RPM instead.
@ unpublished Bug 7322896, Bug 7718320 and Bug 7328490
glibc-common-2.3.4-2.19
glibc-devel-2.3.4-2.19
glibc-headers-2.3.4-2.19
libaio-devel-0.3.105-2
libaio-0.3.105-2
libgcc-3.4.5
libstdc++-3.4.5-2
libstdc++-devel-3.4.5-2
make-3.80-5
sysstat-5.0.5
unixODBC-2.2.11
unixODBC-devel-2.2.11
compat-db-4.1.25-9
compat-libstdc++-296-2.96-132.7.2
control-center-2.8.0-12
gnome-libs-1.4.1.2.90-44.1
pdksh-5.2.14-30
xorg-x11-deprecated-libs-6.8.1-23.EL
openmotif21-2.1.30-11.RHEL4.2 (Required to install Oracle Demos)
* Additionally, the following installation pre-requisites must be met if the specific Oracle product listed is being installed:
Oracle Messaging Gateway
- MQSeriesServer, MQSeriesClient & MQSeriesRuntime
- TIBCO Rendezvous 7.2
Oracle Spatial
- xorg-x11& xorg-x11-devel package
Oracle JDBC/OCI Drivers
- Sun JDK 1.4.2_08 with JNDI extension (installed by Oracle)
Install oracleasm-support package version 2.0.0.1 or higher to use ASMLib.
* Oracle Global Customer Support has noticed a recent trend with install problems that originates from installing too many RPMs. For example:
o installing your own JDK version (prior to beginning the Oracle Software “runInstaller”) is not needed on Linux, and is not recommended on Linux. A pre-existing JDK often interferes with the correct JDK that the Linux Oracle Software “runInstaller” will place and use.
o installing more than the required version of the gcc / g++ RPMs often leads to accidentally using (aka enabling or activating) the incorrect one. If you have multiple RDBMS versions installed on the same Linux machine, then you will likely have to manage multiple versions of gcc /g++ . For more information, please see Note 444084.1, "Multiple gcc / g++ Versions in Linux"
3. Environment:
============
* Modify your kernel settings in /etc/sysctl.conf (RedHat) as follows. If the current value for any parameter is higher than the value listed in this table, do not change the value of that parameter.
kernel.shmall = physical RAM size / pagesize for most systems, this will be the value 2097152. See Note 301830.1 for more information.
kernel.shmmax = 1/2 of physical RAM, but not greater than 4GB. This would be the value 2147483648 for a system with 4Gb of physical RAM.
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 512 x processes (for example 65536 for 128 processes)
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 activate these new settings into the running kernel space, run the “sysctl –p” command
* The gcc and g++ RPM items above will ensure that the correct gcc / g++ versions are installed. It is also required that you ensure that these correct gcc / g++ versions are active, and in-use. Ensure that the commands "gcc --version" and "g++ --version" each return "3.4.x".
* Hostname command should return the fully qualified hostname as shown
below:
% hostname
hostname.domainname
* If any Java packages are installed on the system, unset the Java
environment variables, for example JAVA_HOME.
* The oracle account used to install Oracle 10.2.0.X, should not have the Oracle install related variables set by default. For example setting ORACLE_HOME, PATH, LD_LIBRARY_PATH to include Oracle binaries in .profile, .login file and /etc/profile.d should be completely avoided.
4. Add the following lines into /etc/security/limits.conf
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
Edit the /etc/pam.d/login file to add the following line. If /etc/pam.d/login does not yet exist, then create a file with this line as the only content:
session required pam_limits.so
Depending on the oracle user's default shell, make the following changes to the default shell startup file:
For the Bourne, Bash, or Korn shell, add the following lines in the /etc/profile file (or the /etc/profile.local file on SUSE systems):
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
Without this etc/profile modification, the ulimit values for the oracle account will not be correct.
5. Now you are ready to invoke your Oracle Universal Installer
a.) it is best practice not to use any form of "su" to start the runInstaller, in order to avoid potential problems
