OBIEE 11.1.1.6.0 on Oracle Enterprise Linux 5.5 - PART 1

PART 1- ORACLE DATABASE
PART 2- RCU
PART 3- OBIEE



Hi Guys,

I thought of sharing this with all of you. There was a requirement to setup a LINUX OBIEE server for a POC environment.

The challenge was that:

The Machine was only 2 GB of RAM and 200 GB Of hard disk. (Worst config).
No Prior experience in LINUX. :(

But i managed to bring up the server. If you guys are planning to setup an OBIEE 11G server on a LINUX machine please follow the steps EXACTLY.

Setp 1: You need to have a lot of prerequisites done before starting the OBIEE suit installation.

Download the installables:

Oracle 11gR2 Database
Oracle RCU
OBIEE 11.1.1.6.0

you can download these from the download links given in this blog.

Step 2:

Once you have downloaded all the installables , start the db intallation.

There are some prerequisites for the oracle db install, You need to have all the necessary packages installed.
and the system parameters also set.

For installing the packages, use the YUM package installer.

A) Follow the steps below EXACTLY to install the packages

login as root and execute the following commands.

Use the following commands according to your LINUX version

Oracle Linux 5

# cd /etc/yum.repos.d
# wget http://public-yum.oracle.com/public-yum-el5.repo

Oracle Linux 6

# cd /etc/yum.repos.d
# wget http://public-yum.oracle.com/public-yum-ol6.repo

now the file will be saved to your local drive

For more options you can go to this file and open it in a notepad and enable the versions according to your LINUX.

To install the packages required, you can use the yum server with  following commands.

# cd /
# yum install <package name>

or

for default oracle package installation (recommended) use the command below

# yum install oracle-validated  --The packages will be installed (Press Y  when prompted)
# yum install gcc*
# yum install compat*
# yum install unix*
# yum install libaio*

These commands will also install the remaining dependencies. (retype the command with any of your missing packages)



B) Configure the system parameters

To set the LINUX System parameters follow the below steps EXACTLY

Edit the /etc/sysctl.confand add following lines:  (You can edit this in the note editor -GUI)

These are recommended values , if the values in your current file is LARGER than this , the DO NOT exit that parameter, If else edit it with the below values

# vi /etc/sysctl.conf


kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 6815744
fs.aio-max-nr = 1048576
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 = 1048576


Note: You need reboot system or execute "sysctl -p" command to apply above settings.
/sbin/sysctl -p


 Edit the /etc/security/limits.conf file and add following lines:
# vi /etc/security/limits.conf


oracle    soft  nproc  2047
oracle    hard  nproc  16384
oracle    soft  nofile  1024
oracle    hard  nofile  65536

Restart the machine.

The prerequisites for ORACLE Database is complete
