Configuring Linux for Oracle
Verifying System Requirements
To check the amount of RAM and swap space available, run this:
    grep MemTotal /proc/meminfo
    grep SwapTotal /proc/meminfo
The minimum RAM required is 1024MB, and the minimum required swap space is 1GB. Swap space should be twice the amount of RAM for systems with 2GB of RAM or less and between one and two times the amount of RAM for systems with more than 2GB.
You also need 2.5GB of available disk space for the Oracle Database 10g Release 2 software and another 1.2GB for the database. The /tmp directory needs at least 400MB of free space. To check the available disk space on your system, run the following command:
  df -h  
Filesystem Size Used Avail Use% Mounted on /dev/sda3 6.8G 1.3G 5.2G 20% / /dev/sda1 99M 17M 77M 18% /boot
Create the Oracle Groups and User Account
Create the Linux groups and user account that will be used to install and maintain the Oracle Database 10g Release 2 software. The user account will be called oracle, and the groups will be oinstall and dba. Execute the following commands as root:
    /usr/sbin/groupadd oinstall
    /usr/sbin/groupadd dba
    /usr/sbin/useradd -m -g oinstall -G dba oracle
    id oracle
Set the password on the oracle account:
       passwd oracle
Changing password for user oracle.
    New password:
    Retype new password:
    passwd: all authentication tokens updated successfully.
Create Directories
Now create directories to store the Oracle Database 10gRelease 2 software and the database files.
The following assumes that the directories are being created in the root filesystem. This is done for the sake of simplicity and is not recommended as a general practice.
These directories would normally be created as separate filesystems.
Issue the following commands as root:
    mkdir -p /u01/app/oracle
    chown -R oracle:oinstall /u01/app/oracle
    chmod -R 775 /u01/app/oracle

Hardware and Software Requirements to install Oracle 
Hardware Requirement 
    CPU              PII or K6RAM           
    RAM             512 MB
    HDD space   3.5 GB        
    Swap space   1GB or RAMx2    
Software Requirement
 Oracle requires a minimal version of the kernel and JRE software:
    Parameter       Required        Sufficient (tested)
    ---------------------------------------------------
    Kernel             2.4.7                  later is fine
    JRE                 1.1.8v3              1.1.8v3


First of all before installing oracle in redhat check whether all development packages are installed by the following command
rpm -q gcc cpp compat-libstdc++ glibc-devel glibc-kernheaders binutils
Install the following RPM 
su -root
rpm -ivh binutils-2.13.90.0.18-9.i386.rpm \
cpp-3.2.2-5.i386.rpm \
gcc-3.2.2-5.i386.rpm \
glibc-devel-2.3.2-5.i386.rpm \
glibc-kernelheaders-2.4-8.10.i386.rpm
