2. Preparing the Server to Install Oracle Database creation :
2.1 : Create oracle User Account
Login as root and create te user oracle which belongs to dba group.
#groupadd dba
# useradd -g dba -G dba oradev
# passwd oradev
Note : Need to request Unix admin to create the user
2.2 : Create oracle installation Directory:
Create a Directory with full permission i.e. 755
# pwd
#/u01
#mkdir DEV
# chown –Rh oradba:dba DEV
#chmod –R 755 DEV
Eg: drwxr-xr-x 6 oradev dba 4096 Feb 25 20:06 DEV
Note : Need to request Unix admin to create the installation directory
2.3 . Setting System parameters:
Edit the /etc/sysctl.conf and add following lines:
kernel.sem = 250 32000 100 128
kernel.shmmax = 2147483648
kernel.shmmni = 128
kernel.shmall = 2097152
kernel.msgmnb = 65536
kernel.msgmni = 2878
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000

Note: You need execute "sysctl -p" or reboot system to apply above settings.
Step2.4 Create oraInventory directory :
#pwd
# /u01/DEV
#mkdir oraInventory
# chown –Rh oradba:dba oraInventory
#chmod –R 755 oraInventory
Eg: /u01/DEV/oraInventory
Note: This directory need to be created before starting the runInstaller
Step 2.5 Update the oraInventory location in oraInst.loc file:
Edit the /etc/oraInst.loc and add following lines:
inventory_loc=/u01/DEV/oraInventory
Step 2.6 Download the media from Edelivery.oracle.com
V14230-01_1of2.zip
V14230-01_2of2.zip
Step 2.7 Ftp the media to server and untar the cpio file
Unzip V14230-01_1of2.zip
Unzip V14230-01_2of2.zip
Note : FTP the media to the stage location and untar the software before starting the installation.

Step 2.8 Create the VNC session from oracle OS account to Install the Oracle software.
Eg: # su - oradev
[oradev@myapps1 u01] $ vncserver
[oracle@ssnunx12 stage]$ vncserver
New 'myapps1.dyndns.org:1 (oradev)' desktop is myapps1.dyndns.org:1
Starting applications specified in /home/oradev/.vnc/xstartup
Log file is /home/oradev/.vnc/ myapps1.dyndns.org:1 .log
[oracle@ssnunx12 stage]$ vncpasswd
Password:
Verify:
Step 2.9 login to vncserver
http://myapps1.dyndns.org:5801/
Step 2.10 check if xclock is working in VNC server
Step 2.11 start the runInstaller from VNC session.
Cd /u01/oracle11g_software/database
$ . ./runInstaller

4. Post Installation steps:
4.1 Setup environment file for newly installed Oracle Database
.bash_profile
export ORACLE_HOME=/u01/DEV/oracle
export ORACLE_BASE=/u01/DEV
export ORACLE_SID=DEV
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
Note: ORACLE_SID is case-censetive , set lower or Upper case.
4.2 Verify Database Connection after successful Installation:
[root@myapps1]# su - oradev
[oradev@myapps2 ~]$ sqlplus '/as sysdba'
4.3 Update tnsnames.ora file
/u01/DEV/network/admin
# tnsnames.ora Network Configuration File: /u01/oracle/DISCO/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
DEV=
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=myapps1.dyndns.org)(PORT=1530))
(CONNECT_DATA=
(SID=DEV)
)
)
Note: you need to edit the database port in tnsnames.ora file the same port assigned in Listener.ora
file.
4.3 Update Listener.ora file

(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC9))
(ADDRESS = (PROTOCOL = TCP)(HOST = myapps1.dyndns.org)(PORT = 1530))
)
)
Note: You have to edit the Listener.ora to change the listener name to DEV, by default oracle
Installation names listener as LISTENER and assign default port 1521, but when you are using more
then one database in the server then we need to change the Listener name and Port number to avoid
port and listener name conflict.

3. Know Issue:
3.1 ORA-00845: MEMORY_TARGET not supported on this system
ORA-00845 Memory_target not supported in this system.
ORA-00845: MEMORY_TARGET not supported on this system - Linux Servers [ID 465048.1]
Cause
On Linux systems, insufficient /dev/shm mount size for PGA and SGA.
AMM (Automatic Memory Management) is a New feature in 11G which manages both SGA and PGA
together. Its is managed by MMAN, same as with 10g AMM
MEMORY_TARGET is used instead of SGA_TARGET
MEMORY_MAX_TARGET is used instead of SGA_MAX_SIZE (defaults to MEMORY_TARGET )

It uses /dev/shm on Linux
If max_target set over /dev/shm size, you may get the below error message ::
ORA-00845: MEMORY_TARGET not supported on this system
If you are installing Oracle 11G on a Linux system, note that Memory Size (SGA and PGA), which sets
the initialization parameter MEMORY_TARGET or MEMORY_MAX_TARGET, cannot be greater than the shared
memory filesystem (/dev/shm) on your operating system.
NOTE:
This error may also occur if /dev/shm is not properly mounted. Make sure your df output is similar to the
following:
$ df -k
Filesystem 1K-blocks Used Available Use% Mounted on
...
shmfs 6291456 832356 5459100 14% /dev/shm
Solution
Increase the /dev/shm mountpoint size.
For example:
# mount -t tmpfs shmfs -o size=7g /dev/shm
Also, to make this change persistent across system restarts, add an entry in /etc/fstab similar to the following:
shmfs /dev/shm tmpfs size=7g 0
NOTE: You should check with your OS Administrator and/or alert.log for information on "best" size fo shm.
Steps Done on server to resolve the issue:
Current setting:
[oratest6@myapps1 ~]$ df -h /dev/shm
