Ensure that /etc/hosts 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 ~]$ 

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
