Preparation
1.1 Introduction
We used Gnome as our session manager and logged in with root user on Gnome.
Be sure to have installed developer tools before starting the installation.
1.2 Requirements
1.2.1 Hardware Requirements
Memory requirements:
• 1 GB for the instance with Database Control
Disk space requirements:
• 1.5 GB of swap space
• 400 MB of disk space in the /tmp directory
• Between 1.5 GB and 3.5 GB for the Oracle software
• 1.2 GB for the precon gured database (optional)
• 2.4 GB for the ash recovery area (optional)
1.2.2 Software Requirements
Make sure that you have the following packages (libs): libXp, compat-libstdc++
It is required to have the following packages which you can check with the
following command:
rpm -q binutils compat-db control-center gcc gcc-c++ \
glibc glibc-common gnome-libs libstdc++ libstdc++-devel \
make pdksh sysstat xscreensaver
1.3 Changing the Red Hat Release
As RHEL5 has been released after Oracle 10g was, Oracle 10g does not support
RHEL5 o cially. The latest version 10g supports in RHEL4. So we have to get
round it by changing the release con guration:
echo "rhel4" > /etc/redhat-release
1.4 Creating the oracle user account
We need to create oinstall and dba groups and an oracle account belonging to
them. When logged as root user,
/usr/sbin/groupadd oinstall
/usr/sbin/groupadd dba
/usr/sbin/useradd -m -g oinstall -G dba oracle
Set the password for the oracle user:
passwd oracle
You can set "oracle" as the password too
1.5 Creating the Installation Path and Setting
the Permissions
mkdir -p /u01/app/oracle
chown -R oracle:oinstall /u01/app/oracle
chmod -R 775 /u01/app/oracle
1.6 Con guring Kernel Parameters
We can set the kernel parameters with the following command:
cat >> /etc/sysctl.conf << EOF
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 658576
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 262144
net.core.wmem_default = 262144
net.core.rmem_max = 1048536
net.core.wmem_max = 1048536
EOF
Activate the modi cation with the following command:
/sbin/sysctl p
1.7 Con guring Shell Limits
cat >> /etc/security/limits.conf << EOF
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
EOF
cat >> /etc/pam.d/login << EOF
session required /lib/security/pam_limits.so
EOF
cat >> /etc/profile << EOF
if [ \$USER = "oracle" ]; then
if [ \$SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
umask 022
fi
EOF
cat >> /etc/csh.login << EOF
if ( \$USER == "oracle" ) then
limit maxproc 16384
limit descriptors 65536
umask 022
endif
EOF
1.8 Con guring Hangcheck Timer
modprobe hangcheck-timer hangcheck_tick=30 hangcheck_margin=180
cat >> /etc/rc.d/rc.local << EOF
modprobe hangcheck-timer hangcheck_tick=30 hangcheck_margin=180
EOF
1.9 Environment Settings for Oracle User
In this section, we'll use oracle user.
su oracle
To set the environment variables, apply the following command to append
Oracle-speci c contents to /home/oracle/.bash_pro le:
cat >> /home/oracle/.bash_profile << EOF
# User specific environment and startup programs
umask 022
PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
export LD_LIBRARY_PATH=/usr/lib:/usr/X11R6/lib
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=\$ORACLE_BASE/product/10.2.0/db_1
export ORACLE_SID=orcl
PATH=\$ORACLE_HOME/bin:\$ORACLE_HOME/jdk/jre/lib/i386/server:\
\$ORACLE_HOME/rdbms/lib:\$ORACLE_HOME/lib:\$LD_LIBRARY_PATH:\
/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/sbin:\
/usr/sbin:/root/bin:\$PATH
PATH=\$PATH:\$HOME/bin
export PATH
unset USERNAME
EOF
Activate these variables and the paths with:
source ~/.bash_profile
Chapter 2
Installation
2.1 Running the Installer
In a root terminal,
xhost +
su oracle
Extract the 10201_database_linux32.zip le into /u01, or somewhere else where
oracle user has read right:
unzip 10201_database_linux32.zip -d /u01
cd /u01/database ./runInstaller
The installation dialog will now start. If you face errors about some libs are
not found, consider installing the following packages: libXp compat-libstdc++
from http://www.rpm nd.net
2.2 Installation Steps
1. Select "Advanced Installation" and click Next.
2. Leave "Inventory directory path" and "group name" as it is and click
Next.
3. Leave "Enterprise Edition" selected and click Next.
4. Verify that the following information is true:
Name: OraDb10g_home1
Path: /u01/app/oracle/product/10.2.0/db_1
Be careful that it is not /u01/app/oracle/oracle/product/10.2.0/db_1
5. It will check the prerequisites. Do not start if there are any errors and be
careful about memory and environment variable warnings.
6. Leave "Create a database" selected and click Next.
7. Select Advanced and click Next.
8. Click Install and it will install the database system. Then DBCA starts
automatically, con guring the components you installed so far.
9. Select General Purpose and click Next.
10. Set orcl for Database Name and SID and click Next.
11. Leave "Con gure the Database with Enterprise" checkbox selected and
click Next.
12. Assisgn a common password for SYS account, such as "oracle" and click
next.
13. Select Filesystem and click Next.
14. Select "Oracle-Managed Files" and click Next.
15. Leave recovery area as it is and click Next.
16. If you face a "Database Content" dialog, click Next with no additional
setting.
17. Set Use Unicode (AL32UTF8) as Database Character set and UTF16 as
National Character Set on the "Character Sets" tab.
18. Click Next and OK until you get a con rmation to create the database.
19. Close the information after the database is created. Click Exit.
20. The "Con guration assistant"s will start the components you installed
earlier.
21. You will face a dialog which wants you to execute two sh scripts. Open a
new terminal (as root) and run those scripts:
sh /u01/app/oracle/oraInventory/orainstRoot.sh
sh /u01/app/oracle/product/10.2.0/db_1/root.sh
22. Click OK after you run the scripts.
23. Click Exit.

Post-Installation
3.1 Starting the services
Now, the Oracle instance should be installed and working. Let's check it:
su - oracle
sqlplus / as sysdba
If it says Connected to an idle instance , it means that the instance is not
started. Do the following:
lsnrct start
emctl start dbconsole
sqlplus / as sysdba
startup (in sqlplus session)
You will get some feedback about the current status of the services and the
results of the commands.
3.2 Starting Oracle Instance up on System Startup
3.2.1 Creating the startup bash script
Open a text editor (as root) and put the content below in it, saving the le as
/etc/init.d/dbora :
#!/bin/sh
# chkconfig: 345 99 10
# description: Oracle auto start-stop script.
#
# Set ORA_HOME to be equivalent to the $ORACLE_HOME
# from which you wish to execute dbstart and dbshut;
#
# Set ORA_OWNER to the user id of the owner of the
# Oracle database in ORA_HOME.
ORA_HOME=/u01/app/oracle/product/10.2.0/db_1
ORA_OWNER=oracle
if [ ! -f $ORA_HOME/bin/dbstart ]
then
echo "Oracle startup: cannot start"
exit
fi
case "$1" in
'start')
# Start the Oracle databases:
# The following command assumes that the oracle login
# will not prompt the user for any values
su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl start"
su - $ORA_OWNER -c $ORA_HOME/bin/dbstart
su - $ORA_OWNER -c "$ORA_HOME/bin/emctl start dbconsole"
;;
'stop')
# Stop the Oracle databases:
# The following command assumes that the oracle login
# will not prompt the user for any values
su - $ORA_OWNER -c "$ORA_HOME/bin/emctl stop dbconsole"
su - $ORA_OWNER -c $ORA_HOME/bin/dbshut
su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl stop"
;;
esac
Then, open a root terminal and give the le executable rights:
chmod 755 /etc/init.d/dbora
Then link this script to the les inside /etc/rc3.d:
ln -s /etc/init.d/dbora /etc/rc3.d/S99dbora
ln -s /etc/init.d/dbora /etc/rc4.d/S99dbora
ln -s /etc/init.d/dbora /etc/rc5.d/S99dbora
ln -s /etc/init.d/dbora /etc/rc0.d/K10dbora
ln -s /etc/init.d/dbora /etc/rc6.d/K10dbora
3.2.2 Fixing the dbstart script
The dbstart script, which is called inside the dbora script, has some errors. Open
the le /u01/app/oracle/product/10.2.0/db_1/bin/dbstart as oracle user and
change
ORACLE_HOME_LISTNER=/ade/vikrkuma_new/oracle
to
ORACLE_HOME_LISTNER=$ORACLE_HOME
Otherwise, your listener might not get started.
3.2.3 Flagging the orcl instance to be started
We open the /etc/oratab le and change the last letter from N to Y:
orcl:/u01/app/oracle/product/10.2.0/db_1:N
to
orcl:/u01/app/oracle/product/10.2.0/db_1:Y
3.3 Setting the IP Address
If the instance is running, shut it down with (as oracle user):
sqlplus / as sysdba
shutdown immediate (might cause data loss)
Then, open the /u01/app/oracle/product/10.2.0/db_1/network/admin/tnsnames.ora
le and set your hostname/static IP Address:
HOST = oracle10
Start the instance in sqlplus session:
startup
