I. INSTALLATION OF EBS WITH RAPID INSTALL
With Rapid Install, you can perform the following tasks:
- Install a new, fully configured Oracle E-Business Suite system, including the latest certified Oracle E-Business Suite technology stack and all patches, product family release update packs, release update packs, and other updates available at the time of this Oracle E-Business Suite release.
- Lay down the file system and configure server processes for an upgraded system.
- Install a new database node or Applications node technology stack.
Rapid Install employs a wizard that guides you through the screens used to carry out the selected task. On the wizard screens, you enter configuration values for your system; these will typically be saved in the Oracle E-Business Suite database for later use.
New Installation (Standard)
In a new Standard installation, we need to choose where to install the required nodes (database node and primary Applications node).
New Installation (Express)
In an Express installation, you set up a fully configured, single-user/single-machine system using a few basic configuration parameters, such as database type and name, top-level installation directory, and port pool choice. The remaining directory specifications and mount points are supplied by Rapid Install using default values. An Express installation includes a set of core products and uses the US7ASCII character set.

- File System Space Requirements for Standard Installation:
- At least 300GB. 350GB will be better
File System Space Requirements for Standard Installation
|Applications node file system (includes OracleAS 10.1.2 Oracle Home, OracleAS 10.1.3 Oracle Home, OMMON_TOP, APPL_TOP, and INST_TOP)||35 GB (50 GB on HP-UX Itanium)|
|Database node file system (Fresh install)||55 GB|
|Database node file system (Vision Demo database)||208 GB (210 GB on HP-UX Itanium)|
- Temporary directories and files
- For install time temporary disk space, Rapid Install uses the directory defined by the TMPDIR variable (on UNIX) or TEMP and TMP variables (on Windows).
- We should ensure there is at least 1GB of free temporary space before starting an installation.
- Stage Area
- For a production database install, running Rapid Install from a stage area requires atleast 47 GB to accommodate the file system and database files in the stage area.
III. PREPARATION OF THE R12 INSTALLATION IN REDHAT LINUX
- What is RPM?
The Red Hat Package Manager (RPM) is a toolset used to build and manage software packages on UNIX systems. Distributed with the Red Hat Linux distribution and its derivatives (CentOS is 100% compatible rebuild of the Rehat Enterprise Linux). The rpm files represent application or package that you can install on Linux system.
The naming scheme of RPM files is itself a standardized convention. RPMs have the format
The location of the documentation for installed packages is: /usr/share/doc
HOW TO SEE IF A PACKAGE IS ALREADY INSTALLED?
An interesting command for checking if a package is installed or to find out all packages that match a string is:
rpm -qa | grep -i <rpm_name>
where: q = query;
a = all;
grep=filters content based on certain strings;
HOW TO DEINSTALL A PACKAGE?
From the command above, take the package name (without the architecture and rpm extension) and perform the following command
rpm -e package where: e = erase
2. From the RHEL 5 distribution media
The following i386 packages(RPM) are not part of the OS distribution media and must be downloaded separately from http://oss.oracle.com/projects/compat-oracle/files/EnterpriseLinux for RHEL 5 and installed manually:
The following i386 packages must be installed from the RHEL 5 distribution media. Some rpm are distributed as part of the ‘default’ installation of RedHat Enterprise Linux.
compat-oracle-rhel4-1.0-5 – Not need to install, still works
gcc-4.1.2-33 – Not need to install, still works
openmotif21-2.1.30-11.EL5 –After installing libaio-devel-0.3.106
Additionally, the following RPMs are required for an 11gR1 Database (which is bundled with the 12.1.1 release) on the database tier:
- elfutils-libelf-devel-0.125 – Installed from OS
- elfutils-libelf-devel-static-0.125 – Installed from OS
- unixODBC-2.2.11 -2nd
- unixODBC-devel-2.2.11 -1st
- kernel-headers-2.6 – Installed from OS
Below code is to check whether the required rpm’s are installed in Linux System.
rpm -q compat-glibc-2.3.4-2.26 compat-glibc-headers-2.3.4-2.26 compat-libstdc++-33-3.2.3-61 compat-libstdc++-296-2.96-138 compat-oracle-rhel4-1.0-5 gcc-4.1.2-33 gcc-4.1.2-46.el5 gcc-c++-4.1.2-46.el5 gdbm-1.8.0-26.2.1 glibc-2.5-42 glibc-common-2.5-42 glibc-devel-2.5-42 glibc-headers-2.5-42 libaio-0.3.106-3.2 libgcc-4.1.2-46.el5 libgomp-4.4.0-6.el5 libstdc++-4.1.2-46.el5 libstdc++-devel-4.1.2-46.el5 libXau-devel-1.0.1-3.1 libXp-1.0.0-8.1.el5 make-3.81-3.el5 openmotif21-2.1.30-11.EL5 sysstat-7.0.2-3.el5 xorg-x11-libs-compat-6.8.2-1.EL.33.0.1
After installing these patches (Sets the RPM)
3. Networking – Hosts Name settings
We can do following actions by Terminal itself or by GUI Navigation also.
The /etc/hosts file must contain a fully qualified name for the server:
<IP-address> <fully-qualified-machine-name> <machine-name>
We must configure the host to resolve hostnames to the loopback IP address by modifying the /etc/hosts file to contain the following entries:
127.0.0.1 hostname.domainname hostname
127.0.0.1 localhost.localdomain localhost
Example with hostname = vision and domainname = r12apps.com
Then the hosts will be like this.
[root@vision etc]# cat hosts
#Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 vision.r12apps.com vision
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
Note: The configuration line must be in first place!
After doing so, check that the hostname resolves to the loopback IP address by entering the following command for verifying that our hostname works or not:
Verify that the /etc/sysconfig/network file is formatted as follows: HOSTNAME=<node_name>.<domain_name>
Example with the node_name = vision and domain_name = r12apps.com
[root@vision ~]# cat /etc/sysconfig/network
If the /etc/sysconfig/networking/profiles/default/network file exists, remove it.
[root@vision ~]# rm /etc/sysconfig/networking/profiles/default/network
rm: remove regular file ‘/etc/sysconfig/networking/profiles/default/network’? y
[root@vision ~]# cat /etc/sysconfig/networking/profiles/default/network
cat: /etc/sysconfig/networking/profiles/default/network: No such file or directory
4. Restart of the system
[root@ vision ~]# rebootBroadcast message from root (pts/2) (Sun May 18 09:42:14 2011):The system is going down for reboot NOW!
5. Kernel Setting
Add or amend the following lines in the “/etc/sysctl.conf”
Specifying the parameters in the sysctl.conf file causes the parameters to be set upon reboot.
# Append this one in sysctl.conf
kernel.sem = 256 32000 100 142
fs.file-max = 131072
net.ipv4.ip_local_port_range = 10000 65000
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 262144
kernel.shmmni = 4096
kernel.msgmni = 2878
kernel.shmmax must have the half size of the physical memory (in bytes), and at least 2147483648
Run the following command to change the current kernel parameters:
6. The resolver – DNS parameters
The file /etc/resolv.conf is used by the resolver a library that determines the IP address from an host name. It defines the DNS.These low values may cause attempted network connections to an Oracle database to fail. If this happens, add or update the following entries to these minimum settings in the /etc/resolv.conf file on each server node:
[root@vision ~]# cat /etc/resolv.conf
; generated by /sbin/dhclient-script
7. Limiting user processes
To limit the user processes, open the /etc/security/limits.conf file and change the existing values for “hard” and “soft” parameters as follows. Restart the system after making changes.
* hard nofile 65535
* soft nofile 4096
* hard nproc 16384
* soft nproc 2047
8. Create Operating System Accounts
Before running Rapid Install, you must create the operating system accounts that will be used:
- in the installation of the database node: the oracle account
The operating system user that owns the database node file system and starts the database node services is called the oracle user.
- and Applications node file systems: the applmgr account
The operating system user that owns the Applications node file system and starts the Applications node services is called the applmgr user. The applmgr user is the account that owns the Applications node technology stack (APPL_TOP, COMMON_TOP, OracleAS 10.1.2 Oracle Home, and OracleAS 10.1.3 1-14 Oracle E-Business Suite Installation Guide: Using Rapid Install Oracle Home).
The names of these accounts must be the same on all nodes in an Oracle E-Business Suite system.
We can perform (Reference – Page 27 –in R12.1.1 documentation):
- a single-user installation: one user for the two account
- An Multi-user installations: one user by account.
The default name for the oracle user is ora<SID>. For example, for a production (PROD) environment, the default Oracle OS username might be oraprod.
For the applmgr user, the default name is appl<SID>. For example, for a Vision Demo (VIS) environment, the default Apps OS username might be applvis.
Note: Two common groups that are defined in installations are:
- the oinstall group (which owns the Oracle Inventory information)
- And the dba group whose members have SYSDBA privileges of the database.
[root@vision ~]# groupadd dba
[root@vision ~]# useradd -m -g dba oracle
[root@vision ~]# passwd oravis
[root@vision ~]# useradd -m -g dba applmgr
[root@vision ~]# passwd applvis
- the –m flag indicates that a new home directory should be created,
- -g specified the primary group
o Once the user is created, the password is immediately reset using the passwd command.
9. Maintenance tools
To verify that they are installed, just run the version command and see if you have an answer.
|Required Maintenance Tools||Description||Version command|
|ar||create, modify, and extract from archives||ar V|
|gcc||GNU project C and C++ compiler||gcc –version|
|g++||gcc – GNU project C and C++ compiler||g++ –version|
|ld||The GNU linker||ld –version|
|ksh||KornShell, a standard/restricted command and pro-gramming language||ksh –version|
|make||GNU make utility to maintain groups of programs||make –version|
|X Display Server||Linux – X Windows System (commonly X or X11)||X -version|
a. Inventory Directory – oraInst.loc
As per note 405293.1, on all platforms except Windows, oraInst.loc must exist and point to a valid inventory directory. Specifically:
- oraInst.loc must be located in /etc (for Linux)
- oraInst.loc must point to a valid central inventory location
- the central inventory location must be writable by the owner of the oracle files and the application files
If oraInst.loc does not exist, create it in the proper directory. The contents should look like this: inventory_loc=/d01/oracle/oraInventory
Where: /d01/oracle/oraInventory points to the directory where the central inventory is to be located and must be writable by the owner of the oracle files and the application files. Installation directories
Allow the users to actually create files in the directory, so we need to give permission for oravis in /d01
[root@vision ~]# mkdir -p /d01/oracle/VIS
[root@vision ~]# mkdir -p /d01/oracle/VIS/inst
[root@vision ~]# chown -R oracle:dba /d01
[root@vision ~]# chmod -R 775 /d01
11. Setting Up the Stage Area
As preparation for running Rapid Install, you must run a Perl script that creates the install directory and copies the contents of the Release 12.1.1 software bundle to the appropriate location in the file system, known as the stage area (or staging area).
You must have perl 5.0053 or higher installed, and it must be in PATH. Verify software version (perl).
Give permission for Staging Folder (StageR12) as 777 using chmod.
Unset the ENV environment variable prior to installing installation, as it can alter variables that are set by the Oracle installation scripts. The command unset ENV can be used to unset the variable if necessary.
[root@vision ~]# unset ENV
Oracle HTTP Server Patch (RHEL 5)
Download and apply the patch 6078836 from OracleMetaLink to fix an issue with the Oracle HTTP Server bundled with the E-Business Suite technology stack. Perform the following command as root:
[root@vision ~]# cd /d01/StageR12
[root@vision StageR12]# unzip p6078836_101330_LINUX.zip
[root@vision StageR12]# cd 6078836
[root@vision 6078836]# cp libdb.so.2 /usr/lib
13. Link to Motif library for Oracle Application Server 10.1.2 (on RHEL 5)
Perform the following command (as root on your system) to update a required link to a Motif library prior to re linking or patching the 10.1.2 Application Server Oracle Home:
[root@vision ~]# unlink /usr/lib/libXtst.so.6
[root@vision ~]# ln -s /usr/X11R6/lib/libXtst.so.6.1 /usr/lib/libXtst.so.6
