Set Up

This section shows you how to install Oracle Database 11gR1. It will guide you through the

following steps:

Install Prerequisite package

Create required groups and users

Create directories storing oracle file

Set environment for user oracle

Configure Linux Kernel Parameter

Set shell limits for user oracle

Disable SElinux

Install Oracle

1. Install Prerequisite package

Depending on the products that you intend to install, verify that the following software is

installed on the system

Java Runtime Environment j2re-1.4.2.19

libXp-1.0.0-8.1.el5

binutils-2.17.50.0.6-2.el5

compat-libstdc++-33-3.2.3-61

elfutils-libelf-0.125-3.el5

elfutils-libelf-devel-0.125

gcc-4.1.1-52

gcc-c++-4.1.1-52

glibc-2.5-12

glibc-common-2.5-12

glibc-devel-2.5-12

glibc-headers-2.5-12

libaio-0.3.106

libaio-devel-0.3.106

libgcc-4.1.1-52

libstdc++-4.1.1

libstdc++-devel-4.1.1-52.e15

make-3.81-1.1

sysstat-7.0.0

unixODBC-2.2.11

unixODBC-devel-2.2.11

You want to check whether the packages are installed or not, run the following

command:

# rpm -q make binutils gcc libaio libaio-devel libstdc++

elfutils-libelf-devel sysstat compat-libstdc++ libgcc libstdc++-

devel unixODBC-2.2.11 unixODBC-devel

To install the package, run command:

# yum –y install libXp

2. Create required groups and users

Depending on the Oracle software being installed on this system, you need to create

operating groups and users. The groups and user required to create are dba, oinstall

group and oracle user.

To create these groups and user, enter the following command with user root:

# groupadd oinstall

# groupadd dba

# useradd -m -g oinstall -G dba oracle

# passwd oracle

Check user oracle is belong to oinstall and dba group:

# id oracle

uid=501(oracle) gid=501(oinstall) groups=501(oinstall),502(dba)

3. Create directories storing oracle files

The system need directory to store data file, configuration. You create the folder /u01 and

assign right to it

# mkdir -p /u01/app/oracle/product/11.1.0

# chown -R oracle:oinstall /u01/app

# chmod -R 775 /u01/app

4. Set environment for user oracle

Log into system with user oracle.

Edit file /home/oracle/.bash_profile and insert the following line:

#environment for oracle

ORACLE_BASE=/u01/app/oracle

ORACLE_HOME=$ORACLE_BASE/product/11.1.0/fsrv

ORACLE_SID=fsrvorcl

PATH=$PATH:$ORACLE_HOME/bin

LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib

CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/j

lib

export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH LD_LIBRARY_PATH

CLASSPATH

5. Configure Linux Kernel Parameter

Using gedit to add below information to file /etc/sysctl.conf

fs.file-max = 6553600

kernel.shmall = 2097152

kernel.shmmax = 2147483648

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

net.ipv4.ip_local_port_range = 1024 65000

net.core.rmem_default = 4194304

net.core.rmem_max = 4194304

net.core.wmem_default = 262144

net.core.wmem_max = 262144

net.ipv4.tcp_wmem = 262144 262144 262144

net.ipv4.tcp_rmem = 4194304 4194304 4194304

Checking result, enter command to change the current values of the kernel:

# /sbin/sysctl –p

Enter command to confirm that the values are set correctly:

# /sbin/sysctl –a

6. Set shell limits for user oracle

To improve the performance of the software on Linux system, you must increase the

following shell limits for the oracle user.

As root, edit file /etc/security/limits.conf and insert some text before # End of file

oracle soft nproc 2047

oracle hard nproc 16384

oracle soft nofile 1024

oracle hard nofile 65536

Verify file /etc/pam.d/system-auth to check the existing of two following lines:

session required /lib/security/pam_limits.so

session required pam_limits.so

If you don’t see the first line, insert it.

7. Disable the SElinux

Edit file /etc/selinux/config, find SELINUX and change it to

SELINUX=disabled

8. Install Oracle

To install the Oracle software, you must use the Oracle Universal installer.

Start the Oracle Universal Installer (OUI) by issuing the following command in the

Oracle source directory:

./runInstaller

On Installation Method screen, choose Basic Installation. Check the Oracle home

location and installation type. Select option Create Starter Database

Enter the database name fsrvorcl and password and confirmed password fsrvorcl

You need to specify your Inventory directory. The location should be set to

/u01/app/oracle/oraInventory. Accept the default Operating System group name,

oinstall. Then, click Next.

The installer now verifies that the system meets all the minimum requirements for

installing and configuring the chosen product. Please correct any reported errors

before continuing. When the check successfully completes, click Next.

Oracle Configuration Manager allows you to associate your configuration

information with your Metalink account. You can choose to enable it on this window.

Then, click Next.

Review the Summary window to verify what is to be installed. Then, click Install.

Oracle installation is in progress. Waiting for completion.

The Configure Assistants windows appears.

Your database is now being created.

When the database has been created, you can unlock the users you want to use. Click

OK.

You need to execute orainstRoot.sh and root.sh as the root user

$ su - root

# /u01/app/oraInventory/orainstRoot.sh

# /u01/app/oracle/product/11.1.0/db_1/root.sh

# exit

# exit <- close terminal

Switch back to the Universal Installer and click OK

Click Exit on End of Installation screen. Click Yes to confirm exit

Access database control login. Open IE or Firefox, then enter url:

https://vnfsora01.fsrv.vn:1158/em/

Enter sys as username, fsrvorcl as password and connect as SYSDBA. Click Login

Note: if you can’t access this web console, please start OEM Database Control, listener

and open database.

$ su - oracle

# emctl start dbconsole

# lsnrctl start

# sqlplus “/ as sysdba”

> startup open

The Database Control Home Page appears. Your installation was successful.
