How to Install Oracle EBS R12 on Redhat Enterprise Linux 5.5

Before we begin the wild ride, there a few modifications that needs to be done to the system, a few packages need to be installed. I’ll assume that you have searched for quite a while and maybe you even tried to install the damn thing and ran into errors, so I’ll get right into the process. Here what we’re going to do:

1.    Install Development Tools

2.    Install required packages

3.    Modify the System Configuration and Kernel (don’t panic)

4.    Create Required Users

5.    Install Oracle Apps

Install Development Tools

1	yum groupinstall "Development Tools"

Install required packages

You can either install the following packages using yum or download this file which include all the files.

1.    openmotif21-2.1.30-11.EL5.i386.rpm

2.    xorg-x11-libs-compat-6.8.2-1.EL.33.0.1.i386.rpm

3.    elfutils-libelf-devel-0.125

4.    elfutils-libelf-devel-static-0.125

5.    libaio-devel-0.3.106

6.    unixODBC-2.2.11

7.    unixODBC-devel-2.2.11

Note: You need to make the following modifications after installing openmotif

1 2	$ unlink /usr/lib/libXtst.so.6 $ ln -s /usr/X11R6/lib/libXtst.so.6.1 /usr/lib/libXtst.so.6

Modify the System Configuration and Kernel

Open /etc/sysctl.conf as root

1 2	$ su - root $ vi  /etc/sysctl.conf

then add the following lines at the end of the file

1 2 3 4 5 6 7 8 9 10 11

#Oracle EBS R12.1.1 Kernel Settings kernel.shmall = 2097152 kernel.shmmax = 4294967295 kernel.shmmni = 4096 kernel.sem = 256 32000 100 142 fs.file-max = 327679 net.ipv4.ip_local_port_range = 10000 65000 net.core.rmem_default=262144 net.core.rmem_max=262144 net.core.wmem_default=262144 net.core.wmem_max=4194304

Now lets apply the new settings

1	$ /sbin/sysctl –p

Add the following lines to the /etc/security/limits.conf file:

1 2 3 4 5 6 7

* hard nofile 65535 * soft nofile 4096 * hard nproc 16384 * soft nproc 2047

Add the following lines to the /etc/resolv.conf file:

1 2	options attempts:5 options timeout:15

Now we need to restart the system so the above modifications gets applied.

Create Required Users

We’ll need to create one group dba and two users, oracle and applmgr. The oracle users will be the owner of the database tier folders and services, while the applmgr user will be the owner of the applications tier.

You can either create the group and the users using GUI or use the following commands:

1 2 3 4

$ su - root $ groupadd dba $ useradd –g dba  –d  /home/oracle oracle $ useradd –g dba  –d  /home/applmgr applmgr

Install Oracle Apps

Before we start the installation we need first to create the installation directory. We will name the directory ebs and create at root /.

1 2 3 4 5

$ su - root $ cd / $ mkdir ebs $ chown oracle:dba ebs $ chmod 777 ebs

Now we can start the rapid install wizard. I’ll not be using a staging area but the following applies to both installing from a staging area or from Oracle’s EBS media pack DVDs.
I’ll assume that the DVD-Rom is mounted at /media/cdrom.

// run the following as the oracle user, not root $ cd /media/cdrom/Disk/rapidwiz $ ./rapidwiz         Thanks Srini
