Step 4 According to oracle ,oracle10g didn't support Red Hat Enterprise Linux Server release 5 (Tikanga), so you should modify /etc/redhat-release, just modify Red Hat Enterprise Linux Server release 5 (Tikanga) as redhat-4
And after you had finished the setup , restore the value
Step 5 In the process of installing, oracle setup program will check your preconditions, and a static IP address is needed, else oracle setup program will throw a error message as followed:
Recommendation: Oracle supports installations on systems with DHCP-assigned public IP addresses.
And here is the way to fix it, just do the followed step:
Login the Linux system as root, then modify /etc/hosts, the contents of hosts will look like the followed:
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
59.53.50.67 ringlinux.com ringlinux
Just change 59.53.50.67 as your machine IP address, for example:192.168.1.52
Then you need save what you had modified, so run a command named hostname
$hostname
Once you had run the command, you will get a printed message: Your host name(ringlinux.com), if you can see the message, it means you got it.
Step 6 Create the Oracle Groups and User Account
/usr/sbin/groupadd oinstall
/usr/sbin/groupadd dba
/usr/sbin/useradd -m -g oinstall -G dba oracle
id oracle
Then set password for oracle
Passwd oracle
Step 7 Create directories
Issue the following commands as root:
mkdir -p /opt/oracle
chown -R oracle:oinstall /opt/oracle
chmod -R 775 /opt/oracle
Step 8 Use root edit /home/oracle/.bash_profile, add the followed scripts into it
# Oracle Settings
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR
ORACLE_BASE=/opt/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1; export ORACLE_HOME
ORACLE_SID=orcl; export ORACLE_SID
ORACLE_TERM=xterm; export ORACLE_TERM
PATH=/usr/sbin:$PATH; export PATH
PATH=$ORACLE_HOME/bin:$PATH; export PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536

Step 9 $ ./runInstaller
1. Select Installation Method
* Select Basic Installation
* Oracle Home Location: /u01/app/oracle/product/10.2.0/db_1
* Installation Type: Enterprise Edition (1.3GB)
* UNIX DBA Group: oinstall
* Make sure Create Starter Database is checked
* Global Database Name: demo1
* Enter the Database Password and Confirm Password
* Click on Next
2. Specify Inventory Directory and Credentials
* Inventory Directory: /u01/app/oracle/oraInventory
* Operating System group name: oinstall
* Click on Next
3. Product-specific Prerequisite Checks
* If you've been following the steps in this guide, all the checks should pass without difficulty. If one or more checks fail, correct the problem before proceeding.
* Click on Next
4. Summary
* A summary of the products being installed is presented.
* Click on Install.
5. Configuration Assistants
* The Oracle Net, Oracle Database, and iSQL*Plus configuration assistants will run automatically
6. Execute Configuration Scripts
* At the end of the installation, a pop up window will appear indicating scripts that need to be run as root. Login as root and run the indicated scripts.
* Click on OK when finished.
7. End of Installation
* Make note of the URLs presented in the summary, and click on Exit when ready.
8. Congratulations! Your new Oracle Database 10g Release 2 database is up and ready for use.
Once the oracle setup process had ended, you will be noticed that the usage of visiting oracle as followed:
The following J2EE Applications have been deployed and are accessible at the URLs listed below.
iSQL*Plus URL:
iSQL*Plus DBA URL:
/dba
Enterprise Manager 10g Database Control URL:
Attention: In the installation process, do choose advanced option, and change the character as a type of chinese character,otherwise, chinese character can not display normally.
Reboot the system and login as root, open a ,then su to oracle:
$source .bash_profile dbstart
$sqlplus "/as sysdba"
$startup
$exit(Once the database has been mounted)
$lsnrctl start
$emctl start dbconsole
$dbstart
$isqlplusctl start
you can run command: sqlplus /nolog to login isql@plus
then run command: connect system as sysdba
$dbstop
$emctl stop dbconsole
$lsnrctl stop
Remove Oracle 10g from linux
1. rm -rf /opt/oracle
2. rm -rf /etc/oraInst.loc /etc/oratab
3. rm -rf /usr/local/bin/coraenv /usr/local/bin/oraenv /usr/local/bin/dbhome
4. remove oracle user and group(If you want to redeploy oracle database server,just escape this row);In some situation, if you want to redeploy oracle in the same machine, and you log into X window as oracle user, you will find that you can't log in X window, and fix this promble is log in as root then delete groups: oinstall,dba and user oracle,and recreate them.
