I am trying to create an oracle xe database in my vps.
VPS OS : Cent OS.
When try to run
/etc/init.d/oracle-xe configure
it throws an error Database confiration failed and to check the logs but logs just shows ORA-01034: ORACLE not available
Below is the history...
[root@vmcx-43 Disk1]# rpm -ivh oracle-xe-11.2.0-1.0.x86_64.rpm

You must run '/etc/init.d/oracle-xe configure' as the root user to configure the database.
[root@vmcx-43 Disk1]# /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:
Password can't be null. Enter password:
Password can't be null. Enter password:
Confirm the password:

Add your servers name and IP to the /etc/hosts file
yum install bc
Then try again.
I had same issues.
I uninstalled oracle-xe. See How to reconfigure Oracle 10g xe on Linux
Then followed
yum install bc
rpm -i oracle-xe.rpm
/etc/init.d/oracle-xe configure
Everything went fine.
Ok the solution may sound weird but today i got the exactly same error while installing Oracle Xe on centos. I struggled a lot to find the answer but in the end the problem was the way i was installing the rpm.
Initailly i used the command
$rpm -ivh oracle-xe.rpm
and somehow it was giving the same error which you are getting.
After that i tried
$rpm -i oracle-xe.rpm
and it worked for me. Not very sure why will the "h" flag, which is the hash flag cause an issue but it worked for me.
I too faced the similar issue on Linux Mint 17.3. Fortunately, I found the solution sooner. The issue is simply that your shared memory file is not where Oracle expects it to be i.e. /dev/shm but you'd be having it at /run/shm with /dev/shm linking to it.
So, to resolve this issue, before configuring the database, you must perform the below steps in order
$ sudo rm -rf /dev/shm
$ sudo mkdir /dev/shm
$ sudo mount -t tmpfs shmfs -o size=2048m /dev/shm
I have tested it, works perfect.

/etc/init.d/oracle-xe configure // will work
After googling 'oracle sucks' in frustration over the lack of logging from the installation I managed to resolve the issue that caused the configuration to fail on a docker container running the Hortonworks HDP 2.6 Sandbox:
Oracle XE requires 1 Gb of shared memory and fails otherwise (I didn't try 512 mb) according to https://blogs.oracle.com/oraclewebcentersuite/implement-oracle-database-xe-as-docker-containers.
vi /etc/fstab
change/add the line to:
tmpfs /dev/shm tmpfs defaults,size=1024m 0 0
Then reload the configuration by:
mount -a
Keep in mind that if you later restart the docker container you might have to do 'mount -a' once more as it starts with the default set on the container ~ 65 mb.
Normally the failed configuration will have succeeded in creating a listener and you will have to kill this before rerunning configuration.
ps -aux | grep tnslsnr
kill {process identified in the step above}
Lost a full day to this one as none of the other answers on this page worked for me (Ubuntu).
Proper instructions where here
The main trick missing from other tutorials was to execute
sed -i 's,/var/lock/subsys,/var/lock,' /etc/init.d/oracle-xe
before
/etc/init.d/oracle-xe configure
check the permissions for: /u01/
In my case these were set to root:root I changed this to oracle:dba and it worked for me.
But before that I tried the following:
- Setting up the
IP/hostnamein the/etc/hosts - installing bc and reinstalling oracle
both the steps did not work for me but I uninstalled and reinstalled oracle-xe, changed permissions and then ran the command for configure.
