$ swapon tmpswap

Check TMP Space
Oracle Universal Installer (OUI) requires up to 400 MB of free space in the /tmp directory. How to check the space in /tmp?
$ df /tmp

If you don’t have enough space in the /tmp filesystem, you must temporarily create a tmp directory in another filesystem. Bellow I am describing all steps for adding temp space?

Step 1

Log in as a ROOT user

Step 2 mkdir //tmp

Step 3 chown root.root //tmp

Step 4 chmod 1777 //tmp

Step 5 export TEMP=/

Step 6 export TMPDIR=/

After Completion of Installation, you must remove the temporary /temp directory. Bellow I am describing How to Remove temprory /temp directory?

Step 1 Log in as a Root
Step 2 $ rmdir //tmp

Step 3 $unset TEMP

Step 4 unset TMPDIR

4. Check Software RPM Package
Before install of Oracle Database 10g software you need to check the system for required RPMs.

make-3.79
binutils-2.14
gcc-3.2
libaio-0.3.96

Checking Recommended glibc version
Glibc-2.3.2-95.27

5. Check Kernel parameter

How to see all kernel parameters?

Step 1 Log in as a Root user
Step 2 $ sysctl –a

Bellow I am describing kernel parameters, which have to be set to values greater than or equal to the recommended values which can be changed in the proc filesystem:

shmmax = 2147483648
shmmni = 4096
shmall = 2097152
shmmin = 1
shmseg = 10
semmsl = 250
semmns = 32000
semopm = 100
semmni = 128
file-max = 65536
ip_local_port_range = 1024 65000

NOTE: Do not change the value of any kernel parameter on a system where it is already higher than listed as minimum requirement.

Note: Just you add minimum required value in /etc/sysctl.conf file which is used during the boot process: kernel.shmmax=2147483648kernel.sem=250 32000 100 128fs.file-max=65536net.ipv4.ip_local_port_range=1024 65000net.core.rmem_default=1048576net.core.rmem_max=1048576net.core.wmem_default=262144net.core.wmem_max=262144

become effective immediately, execute the following command:
Step 1 Log in as a Root

Step 2 $ sysctl -p

Installation Steps:

1. Creating Oracle User Accounts and Group

Step 1 Log in as a Root
Step 2 $groupadd dba # group of users to be granted SYSDBA system privilege
Step 3 $groupadd oinstall # group owner of Oracle files
Step 4 useradd -c “Oracle software owner” –d /home/oracle -g oinstall -G dba oracle
Step 5 chown oracle:dba /home/oracle /oracle
Step 6 chown oracle:dba /home/oracle /database
Step 5 passwd oracle

2. Creating Oracle Directories
You only need to create the directory for $ORACLE_BASE:
su – root
mkdir /oracle
chown –R oracle:oinstall /oracle

3
Starting Oracle Universal InstallerInsert the Oracle CD that contains the image of the Software. If you install Oracle10g from a CD, mount the CD by running the following commands in another terminal:

su – root
mount /mnt/cdrom
run installer ./ runInstaller

Note: Message :- Can not connect to X11 windows server
Step Log in as a Root user
Step 2 $xhost +
Step 3 su – oracle
Step 4 Export Display=localhost:0.0
Step 5 ./runinstaller

Put following entries in bash file.

export ORACLE_HOME=$ORACLE_BASE/oracle/product/10.2.0/db_1

export PATH=$PATH:$ORACLE_HOME/bin

export LD_LIBRARY_PATH=$ORACLE_HOME/lib
