How to install Oracle Database 11g Express Edition on Ubuntu 12.10?
- by Praneeth Pj
I installed the Oracle database following the steps mentioned in this blog.
Downloaded 11g express edition
Created a new user oracle under the group dba. Following steps are executed using this.
Unzipped oracle-xe-11.2.0-1.0.x86_64.rpm.zip and then converted the rpm to the Ubuntu package by running:
sudo alien --scripts -d oracle-xe-11.2.0-1.0.x86_64.rpm
Created /sbin/chkconfig file and added the entries as specified there.
Created /etc/sysctl.d/60-oracle.conf and added the entries as specified in the same link as above.
Running the commands:
ln -s /usr/bin/awk /bin/awk
mkdir /var/lock/subsys
touch /var/lock/subsys/listener
.deb generated in step 3:
sudo dpkg --install oracle-xe_11.2.0-2_amd64.deb
Left the default values as it is:
sudo /etc/init.d/oracle-xe configure
Set the following env variables in ~/.bashrc file:
export ORACLE_HOME=/u01/app/oracle/product/11.2.0/xe
export ORACLE_SID=XE
export NLS_LANG=`$ORACLE_HOME/bin/nls_lang.sh`
export ORACLE_BASE=/u01/app/oracle
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH
export PATH=$ORACLE_HOME/bin:$PATH
Running the commands:
chown -R oracle:dba /var/tmp/.oracle
chmod -R 755 /var/tmp/.oracle
chown -R oracle:dba /tmp/.oracle
chmod -R 755 /tmp/.oracle
Starting Oracle Database 11g Express Edition instance:
sudo service oracle-xe start
sqlplus / as sysdba and got the following:
SQL*Plus: Release 11.2.0.2.0 Production on Thu Jan 3 09:41:58 2013
Copyright (c) 1982, 2011, Oracle. All rights reserved.
Connected to an idle instance.
Now when exectuting any SQL statements on SQLplus, I end up with the following error:
SQL> select * from dual;
select * from dual
*
ERROR at line 1:
