Problems installing Oracle Database Express Edition 11g

I'm trying to install Oracle Database in (X)ubuntu 13.04 64-bit using [this guide](

). Everything goed well until I get to the following step:

$ sudo /etc/init.d/oracle-xe configure

Oracle Database 11g Express Edition Configuration
-------------------------------------------------
This will configure on-boot properties of Oracle Database 11g Express
Edition. The following questions will determine whether the database should
be starting upon system boot, the ports it will use, and the passwords that
will be used for database accounts. Press <Enter> to accept the defaults.
Ctrl-C will abort.

Specify the HTTP port that will be used for Oracle Application Express [8080]:

Specify a port that will be used for the database listener [1521]:

Specify a password to be used for database accounts. Note that the same
password will be used for SYS and SYSTEM. Oracle recommends the use of
different passwords for each database account. This can be done after
initial configuration:
Confirm the password:

What am I doing wrong?

[This link looks like it has the answer.][1] You need to make sure that /dev/shm is mounted on your system, and assign it memory of at least MEMORY_TARGET.

You can do this by adding the following to your fstab, and rebooting. (This will set the /dev/shm size to 2gb):

shmfs /dev/shm tmpfs size=2048m 0 0

There are several packages that need to be installed first, plus some kernel parameters that have to be changed before you can actually start the database. Consult Oracle's installation guide for Linux, or search Google for specific guides for Oracle 11gR2 XE on Ubuntu.

nano /etc/init.d/oracle-shm

add text

#! /bin/sh
# /etc/init.d/oracle-shm
#
case "$1" in
start)
echo "Starting script /etc/init.d/oracle-shm"
# Run only once at system startup
if [ -e /dev/shm/.oracle-shm ]; then
echo "/dev/shm is already mounted, nothing to do"
else
rm -f /dev/shm
mkdir /dev/shm
mount --move /run/shm /dev/shm
mount -B /dev/shm /run/shm
touch /dev/shm/.oracle-shm
fi
;;
stop)
echo "Stopping script /etc/init.d/oracle-shm"
echo "Nothing to do"

echo "Usage: /etc/init.d/oracle-shm {start|stop}"
exit 1

#

### END INIT INFO

make the file executable

chmod 755 /etc/init.d/oracle-shm
/etc/init.d/oracle-shm start


At this stage reboot, then check

df -kh /dev/shm

further proceed to emulate chkconfig and continue with rest of configuration and install

dpkg -i oracle-xe-11.2.0-1.0.x86_64.deb

Check the environment variables and ORACLE_HOME and start database

Check your /etc/hosts file. It should looks like

127.0.0.1 localhost.localdomain localhost hostname.domain hostname

I was in the same boat, trying to configure XE on a virtual machine (**openSUSE** 13.01 64bit).

The solution in my case was the missing hostname in `/etc/hosts`.
You can examine the errors in `/u01/app/oracle/product/11.2.0/xe/config/log/CloneRmanRestore.log` at the very beginning (the path depends on your XE version).

Search for an info similar to:
`ORA-00119: invalid specification for system parameter LOCAL_LISTENER ORA-00130: invalid listener address '(ADDRESS=(PROTOCOL=TCP)(HOST=linux-cn65.site)(PORT=1521))`

So **linux-cn65.site** (the VM host) was missing. Add your host in /etc/hosts (as root):


`127.0.0.1 linux-cn65.site` <-- your host here

and run the configuration again (as root): `sh /etc/init.d/oracle-xe configure`

**Additional trickery**

- if you do not have the error files in the log folder, you may re-install XE without **h** flag, like this:
- to find your package: `sudo rpm -qa | grep -i oracle`
- to remove it: `sudo rpm -e oracle-xe-11.2.0-1.0.x86_64` <-- your package here

- install again without h flag: `sudo rpm -iv oracle-xe-11.2.0-1.0.x86_64.rpm`

oh, replace the version (oracle-xe-11.2.0-1.0.x86_64.rpm) with yours. Cheers ;)

I struggled with this too. I have tried a few different solutions, but still got the problem. I "fixed" it by removing memory_target from the database configuration:


sqlplus / as sysdba
create pfile=‘<path>’ from spfile
!vi <path>

Add # in front of the line with memory_Target, save and close file.

startup from pfile=‘<path>'
create spfile from pfile=‘<path>’

This solution works nice with my XE database, hope it helps.

I had this exact issue with Ubuntu 14.04. The issue came down to Oracle-XE expecting sufficient space at /dev/shm while ubuntu has changed to using /run/shm with a symlink from /dev/shm.

The solution that worked for me was to create the file /etc/rc2.d/S01shm_load containing:

#!/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
;;
esac

I got this from

which is similar to many other pages on installing XE but was the only one with this solution.

PS. The file permissions are set at 755 so you will need to execute:

`sudo chmod 755 /etc/rc2.d/S01shm_load`

to set the permissions on this file.
