STEPS FOR INSTALLING ORACLE 11gR2 DB SERVER:
- Download Oracle DB Server and Prepare it to Install
- Check OS level Parameters Required
- Kernel Parameters Setup
- Security Limits Setup
- RPM Packages Installation for Oracle
- Users and Groups creation
- Directories and Permissions Setup
- Install RDBMS (Oracle DB Server) software
- Check the Installed RDBMS software
Downloading Oracle DB Server software and Prepare it ready to Install:
Download the software from the below given Links..
From anyone of those links, we can get the oracle software as two seperate .zip files as below
Linux.x64_11gR2_database_1of2.zip
Linux.x64_11gR2_database_2of2.zip
Now we have to goto that files location and Unzip those files
$unzip *.zip
Then we can get a single directory for those two files named as "database"
$cd database
$ls
$cd
Checking OS level Parameters Required:
Before the Oracle software, We have to know about our Operating System.
To Know about the Flavour and Version of OS, use below commands
$cat /etc/* release
$cat /etc/redhat-release
$uname -r
$uname -a
$lsb_release -a
To know the Bit Version of the Operating System whehter it is 32-bit or 64-bit
$getconf LONG_BIT
To work with the Oracle databse, we require minimum 1GB RAM atleast. To know about the allocated RAM size
$cat /proc/meminfo | grep memtotal
To know the currently allocated SWAP size
$cat /proc/meminfo | grep swaptotal
While Installing Oracle software, the TEMP space must be available about 5GB. So to check the available tmp space
$df -h /tmp
To check the mount point size where you want the oracle software
$df -h /uo1
Kernel Parameter Setup:
-
Automatic Setup(From Online)
#yum
install oracle-validated
#yum
update
( OR )
( OR )
-
Manual Setup
#vi
/etc/sysctl.conf
#(Add the
following lines in this file)
fs.suid_dumpable = 1
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
# semaphores: semmsl, semmns, semopm, semmni
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default=262144
net.core.rmem_max=4194304
net.core.wmem_default=262144
net.core.wmem_max=1048586
:wq!
-
Run the following command to change the current
kernel parameters
# /sbin/sysctl -p
Security Limits Setup:
-
Add the following lines to the below file
#vi
/etc/security/limits.conf
oracle soft nproc 2047
oracle hard nproc
16384
oracle soft nofile 4096
oracle hard nofile
65536
oracle soft stack 10240
:wq!
RPM Packages Installation for Oracle:
-
Install the following RPM packages, If they are
not already present
-
From Oracle Linux 5 DVD
#cd /media/cdrom/Server
#rpm -Uvh binutils-2.*
#rpm -Uvh compat-libstdc++-33*
#rpm -Uvh
compat-libstdc++-33*.i386.rpm
#rpm -Uvh elfutils-libelf*

#rpm -Uvh unixODBC-devel-2.*
#rpm -Uvh numactl-devel-*
#cd /
eject
Users and Groups creation:
#groupadd oinstall
#groupadd dba
#useradd -g
oinstall -G dba
oracle
#password oracle
Directories and Permissions Setup:
#chmod -R 777 /u01
#chown -R oracle:oinstall /u1
#mkdir -p
/u01/app/oracle/product/11.2.0/db_1
#xhost +
#su -oracle
$ vi .bash_profile
export
ORACLE_BASE=/u01/app/oracle;
export
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1;
export
PATH=$ORACLE_HOME/bin:$PATH;
export
LD_LIBRARY_PATH=$ORACLE_HOME/lib;
:wq!
$
Install RDBMS (Oracle DB Server) Software:
- Goto
the directory “database”
where the oracle software is kept ready by unzipping the 2 software files
above.
-
Start the Oracle Universal Installer (OUI) by
issuing the following command in the “database”
directory.
$cd database/
$ . /runInstaller
-
From here onwords, we get the installation
process as Graphically..
-
For above window, uncheck the “Security Upadates”
option and then click on NEXT.
-
Check “Ignore
all” option from right side top of window and then click NEXT.
-
Now Click on FINISH button.
-
Click on OK button of POPUP window.
-
We must Execute the above 2 Scripts as a ROOT
users
#/u01/app/oraInventory/orainstRoot.sh
#/u01/app/oracle/product/11.2.0/dbhome_1/root.sh
-
Now click on the CLOSE button.
-
Now check the Oracle DB Server is installed or
not
#find /
-name oraInst*
oraInst.loc file shows the location of inventory
files. There are 2 types of Inventory files are there.They are
1. Gloabal Inventory
It contains the consolidated
information about all the oracle db server softwares installed on this machine.
There is only one Gloabal
Inventory file for the entire server.
$cat
oraInst.loc
$cd /home/oracle/oraInventory
$ls
$cd contentsXML/
$ls
$cat inventory.xml
2. Local Inventory
It contains the information about
all the components which are being installed with the certain oracle product.
The name of the local inventory
is conps.xml
The location of the local
inventory is specified by ORACLE_HOME.
$cd conps.xml
