I have been struggling to install Oracle 11g Express Edition on Ubuntu 12.04.1 LTS version.
I have followed these steps:
-
Downloaded 11g express edition from Oracle's site
-
Created a new user 'oracle' under the group dba. Following steps are executed using this.
-
unzip oracle-xe-11.2.0-1.0.x86_64.rpm.zip and then Converted the rpm to the Ubuntu package
sudo alien --scripts -d oracle-xe-11.2.0-1.0.x86_64.rpm
-
Created
/sbin/chkconfig
file and added the entries as specified here -
Created
/etc/sysctl.d/60-oracle.conf
and added the entries as specified in same link as above. -
Below steps:
ln -s /usr/bin/awk /bin/awk
mkdir /var/lock/subsys
touch /var/lock/subsys/listener
-
sudo dpkg --install oracle-xe_11.2.0-2_amd64.deb
(.deb generated in step 3) -
sudo /etc/init.d/oracle-xe configure
(left the default values as it is) -
Set the following env variables in
~/.bashrc
fileexport 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
-
Below steps:
chown -R oracle:dba /var/tmp/.oracle chmod -R 755 /var/tmp/.oracle chown -R oracle:dba /tmp/.oracle chmod -R 755 /tmp/.oracle
-
sudo service oracle-xe start
(I didn't see any issues in this step)
12 . 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 exectute any SQL statements on SQLplus, i end up with the following error
SQL> select * from dual;
select * from dual
*
ERROR at line 1:
ORA-01034: ORACLE not available
Process ID: 0
Session ID: 0 Serial number: 0
I have increased the swap memory as specified in here
free -m
total used free shared buffers cached
Mem: 1652 1596 56 0 53 1356
-/+ buffers/cache: 186 1466
Swap: 2943 0 2943
Can you guide me here? I am clueless.

Finally, after a day long struggle
These did the trick.
Make sure that these are executed before the database is configured.
