Oracle 11g Database on linux Redhat Server 5.5
1. Install Linux Redhat Enterprise Server 5.5:
Create a virtual machine using VirtualBox, Hyper-v or Vmware. Attach the iso to the VM. Start the installation:
 |
| Press "Enter" to install with graphical mode |
 |
| Choose "Skip" to ignore the testing of the CD media |
 |
| Choose the language |
 |
| Select the language of the keyboard |
 |
| If you have a Subscription number you can add it for update or install other packages from Redhat |
 |
| Format the Disk but we will go back again to modify the swap |
 |
| Modify the swap size (x2 physical memory) |
 |
| Enter a password for the root account |
 |
| Disable the Firewall |
 |
| Disable SELinux |
 |
| Enter a user account and set a password |
 |
| Login with root account |
The install of Redhat server is complete, we need to make other configuration.
Open a terminal and tape "setup". Go to "Network configuration"
 |
| Select "Edit Devices" |
 |
| Choose the network device |
 |
| Fix the IP address and validate with "OK" |
 |
| We need to change the hostname and fix the DNS address |
 |
| Enter the Hostname |
 |
| Oracle install needs a graphical install, so it's better to change the Display sittings |
 |
| Reboot the system after these changes |
We'll configure the repository so we can install the packages we need for Oracle. Insert the CD media of Redhat Server and copy "Server" folder in "/tmp"
Now go to "Applications" and "Add/Remove Software"
Click "Edit" and "Repository Manager". Click on "Add"
Give a name for the repository and specified the "Server" folder.
Now let’s create a user and groups for Oracle installation
#groupadd oinstall
#groupadd dba
#useradd -m -g oinstall -G dba -d /home/oracle -s /bin/bash -c "Oracle Software Owner" oracle
#passwd oracle
Change the "/etc/sysctl.conf" file to add (change) kernel parameters that are required for Oracle installation
The file should be as follows:
net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
kernel.sysrq = 0
kernel.core_uses_pid = 1
net.ipv4.tcp_syncookies = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.shmmax = 2147483648
kernel.shmall = 2097152
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 6815744
fs.aio-max-nr = 1048576
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 1048576
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
 |
| To make the active in the current session, run /sbin/sysctl -p command |
Change "/etc/pam.d/login" file and add the followingn line:
session required pam_limits.so
Change "/etc/security/limits.conf" and add the following lines:
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
Create necessary directories for Oracle home
#mkdir -p /u01/home/oracle/product/11.2.0/db_1
#chown -R oracle:oinstall /u01
Change the entry of .bash_profile file of the oracle user and add following lines:
/home/oracle/.bash_profile
export ORACLE_HOME=/u01/home/oracle/product/11.2.0/db_1
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib
export PATH=$ORACLE_HOME/bin:$PATH
Now copy downloaded oracle installation files to the /tmp directory
You need to logout from root account and login with oracle account. Open a terminal, point to install directory and execute this command (Before that make sure that oracle user has the right to execute from the install directory, so use chmod to grant these rights):
#cd /tmp/database
#./runinstaller
 |
| Select Create and configure a database and click next |
 |
| Provide the name of the database and the password and click next |
You'll get some errors, no worries you need to install these packages.
Check again.
Our database
The installation finished successfully.
Switch to the installation page and run both shell scripts with root user.
Login in with oracle user, open a new terminal, export ORACLE_SID variable and connect to the database.
#export ORACLE_SID=orcl
