Oracle Applications(Apps) R12 (12.1.1) Installation on Linux

Step by Step instructions to install Oracle Applications R12(12.1.1) on Oracle Enterprise Linux 4 or RHEL 4 are described in this article. This is a single node installation, meaning that the database, all product directories and AD core directories, and all servers (concurrent processing, forms, and Web) are installed on a single node under one common APPL_TOP.
Rapid Install installs the Java Development Kit (JDK) 5.0 automatically. Oracle Applications Software from Oracle eDelivery is already staged. If you have got the CDs, Stage them using $ perl /mnt/cdrom/Disk1/rapidwiz/adautostg.pl

Here is the environment I have used in the installation process:

OS	OEL 4 Update 8
Memory	12GB
Disk Space	100GB Disk (73GB required for fresh install ; 161GB for Vision)
Server Name	erp.freeoraclehelp.com
Installation Type	Single Node installation & Fresh database
Applmgr user	oracle
DB Tier Base	/oracle/erp/R12

Pre-Install Tasks

Download the software from http://edelivery.oracle.com; Select E-Business Suite for Product Pack.
Ensure that /etc/hosts, /etc/resolv.conf, and /etc/oraInst.loc are set right:

[oracle@erp ~]$ cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1       localhost.localdomain localhost
192.168.1.50    erp.freeoraclehelp.com erp
[oracle@erp ~]$ cat /etc/oraInst.loc 
inventory_loc=/oracle/erp/R12/oraInventory
inst_group=oinstall
[oracle@erp ~]$ cat /etc/resolv.conf 
search freeoraclehelp.com
nameserver 192.168.1.1
# R12 Recommendations #

# R12 Recommendations #
[oracle@erp ~]$ 

Create OS User:

# groupadd oinstall -g 2000
# useradd -g oinstall -u 2000 oracle
# chown -R oracle:oinstall /oracle

Set Kernel Parameters:

[root@erp ~]#  tail /etc/sysctl.conf
# Oracle Recommendations for Apps  #
kernel.shmall = 2097152
kernel.shmmax = 4294967295
kernel.shmmni = 4096
kernel.sem = 256 32000 100 142
fs.file-max = 131072
net.ipv4.ip_local_port_range = 10000 65000
kernel.msgmni = 2878
kernel.msgmax = 8192
kernel.msgmnb = 65535
net.core.rmem_default = 262144
net.core.wmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_max = 262144
# Oracle Recommendations for Apps  #

[root@erp ~]# sysctl -p

Increase user limits: Add the following to  /etc/security/limits.conf

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

Add the following to /etc/profile

if [ $USER = "oracle" ]; then 
        if [ $SHELL = "/bin/ksh" ]; then 
              ulimit -p 16384 
              ulimit -n 65536 
        else 
              ulimit -u 16384 -n 65536 
        fi 
fi
