These install instructions are adapted from Me and My Ubuntu blog.
1. Download VirtualBox
Download the VirtualBox application for your host machine type from the virtual box download site.
2. Install VirtualBox
Doubleclick on the downloaded installer and follow the instructions.
3. Download Ubuntu
Download Ubuntu Desktop Edition (14.04 64 bit version). Note the directory where you downloaded it.
4. Start the VirtualBox application
5. Create a virtual machine (VM) and install Ubuntu
Make sure that you set the memory of the VM to be greater than 2GB and the storage of the VM to be at least 10GB. See screencast
6. Clone backups of your Ubuntu VM
7. Download Oracle Database Express Edition
8. Follow pre-install instructions
See screencast, but note that the screencast did not include the last step before REBOOT listed below. You should execute the commands in the last step.
- Unzip using the command:
- Install required packages using the command:
sudo apt-get install alien libaio1 unixodbc
- Convert RPM package format to DEB package format (that is used by Ubuntu) using the command:
sudo alien --scripts -d oracle-xe-11.2.0-1.0.x86_64.rpm
- Create the required chkconfig script using the command::
sudo pico /sbin/chkconfigThe pico text editor is started and the commands are shown at the bottom of the screen. Now copy and paste the following into the file and save:
#!/bin/bash # Oracle 11gR2 XE installer chkconfig hack for Ubuntu file=/etc/init.d/oracle-xe if [[ ! `tail -n1 $file | grep INIT` ]]; then echo >> $file echo '### BEGIN INIT INFO' >> $file echo '# Provides: OracleXE' >> $file echo '# Required-Start: $remote_fs $syslog' >> $file echo '# Required-Stop: $remote_fs $syslog' >> $file echo '# Default-Start: 2 3 4 5' >> $file echo '# Default-Stop: 0 1 6' >> $file echo '# Short-Description: Oracle 11g Express Edition' >> $file echo '### END INIT INFO' >> $file fi update-rc.d oracle-xe defaults 80 01
- Change the permission of the chkconfig file using the command:
sudo chmod 755 /sbin/chkconfig
- Set kernel parameters. Oracle 11gR2 XE requires additional kernel parameters which you need to set using the command:
sudo pico /etc/sysctl.d/60-oracle.confCopy the following into the file and save:
# Oracle 11g XE kernel parameters fs.file-max=6815744 net.ipv4.ip_local_port_range=9000 65000 kernel.sem=250 32000 100 128 kernel.shmmax=536870912Verify the change using the command:
sudo cat /etc/sysctl.d/60-oracle.confYou should see what you entered earlier. Now load the kernel parameters:
sudo service procps startVerify the new parameters are loaded using:
sudo sysctl -q fs.file-maxYou should see the file-max value that you entered earlier.
- Set up /dev/shm mount point for Oracle. Create the following file using the command:
sudo pico /etc/rc2.d/S01shm_loadCopy the following into the file and save.
#!/bin/sh case "$1" in start) mkdir /var/lock/subsys 2>/dev/null touch /var/lock/subsys/listener rm /dev/shm 2>/dev/null mkdir /dev/shm 2>/dev/null mount -t tmpfs shmfs -o size=2048m /dev/shm ;; *) echo error exit 1 ;; esacChange the permissions of the file using the command:
sudo chmod 755 /etc/rc2.d/S01shm_load
- [This step was not included in the screencast, but you should do it.] Execute the following commands:
sudo ln -s /usr/bin/awk /bin/awk sudo mkdir /var/lock/subsys sudo touch /var/lock/subsys/listener
- REBOOT your Ubuntu VM.
9. Install Oracle
See screencast for a recording of the following steps.
- Install the oracle DBMS using the command:
sudo dpkg --install oracle-xe_11.2.0-2_amd64.deb
- Configure Oracle using the command:
sudo /etc/init.d/oracle-xe configureEnter the following information:
- A valid HTTP port for the Oracle Application Express (the default is 8080)
- A valid port for the Oracle database listener (the default is 1521)
- A password for the SYS and SYSTEM administrative user accounts
- Confirm password for SYS and SYSTEM administrative user accounts
- Whether you want the database to start automatically when the computer starts (next reboot).
- Setup environment variables by editting your .bashrc file:
pico ~/.bashrcAdd the following lines to the end of the file:
export ORACLE_HOME=/u01/app/oracle/product/11.2.0/xe export ORACLE_SID=XE export NLS_LANG=`$ORACLE_HOME/bin/nls_lang.sh` export ORACLE_BASE=/u01/app/oracle export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH export PATH=$ORACLE_HOME/bin:$PATHLoad the changes by executing your profile:
- Start the Oracle 11gR2 XE:
sudo service oracle-xe start
- Add user YOURUSERNAME to group dba using the command
sudo usermod -a -G dba YOURUSERNAME
10. Using the Oracle XE Command Shell
See screencast for a recording of the following steps.
- Start the Oracle XE 11gR2 server using the command:
sudo service oracle-xe startThis step is most likely not necessary, but I am documenting the command here anyway.
- Start command line shell as the system admin using the command:
sqlplus sys as sysdbaEnter the password that you gave while configuring Oracle earlier. You will now be placed in a SQL environment that only understands SQL commands.
- Create a regular user account in Oracle using the SQL command:
create user USERNAME identified by PASSWORD;Replace USERNAME and PASSWORD with the username and password of your choice. Please remember this username and password. If you had error executing the above with a message about resetlogs, then execute the following SQL command and try again:
alter database open resetlogs
- Grant privileges to the user account using the SQL command:
grant connect, resource to USERNAME;Replace USERNAME and PASSWORD with the username and password of your choice. Please remember this username and password.
- Exit the sys admin shell using the SQL command:
- Start the commandline shell as a regular user using the command:
sqlplusYou will be prompted for a username and password. Once authenticated, you will be able to type in the standard SQL commands learned in class.
11. Clone your VM if everything was successful!
