Oracle XE 11g Release 2 for Linux x64


The Oracle XE installer depends on the following packages. Make sure that you have already installed them before the following steps.

  • libaio >= 0.3.104
  • unzip
  • bc

The Oracle XE requires at least 2GB swap space. The command swapon -s shows swap usage summary.

% swapon -s
Filename        Type    Size  Used  Priority
/dev/mapper/VolGroup00-LogVol01         partition 1048568 104736  -1

If there is no swap space or the current swap space doesn’t have enough size, add another swap space. The following example creates a /swap file and then enables it.

% dd if=/dev/zero of=/swap bs=1M count=2048
% mkswap /swap
% swapon /swap

And more, in order to mount the /swap file on startup, add its entry to /etc/fstab.

% vi /etc/fstab
/swap swap swap defaults 0 0

Make sure that the server can resolve an IP address to the assigned HOSTNAME. For instance, by default, any Amazon Linux servers on AWS VPC might not have an IP entry to the host name ip-xxx-xxx-xxx-xxx.

% vi /etc/hosts   localhost localhost.localdomain   ip-10-0-1-23

Now install the rpm package and then issue the service script oracle-xe configure.

% rpm -ivh oracle-xe-11.2.0-1.0.x86_64.rpm
% /etc/init.d/oracle-xe configure

To uninstall the package, just use the command rpm -e <package>.

% rpm -e oracle-xe-11.2.0-1.0.x86_64

The oracle user has been created as an administrator, who joins the dba group. The user must load the script bin/ before using any Oracle commands.

% su - oracle
% source /u01/app/oracle/product/11.2.0/xe/bin/

In practice, you should add a script to ~/.bash_profile for later use.

% cat ~/.bash_profile
source /u01/app/oracle/product/11.2.0/xe/bin/
