Install Oracle Database XE on CentOS 5.2

gene -

Oracle Database XE – “Oracle Database 10g Express Edition (Oracle Database XE) is an entry-level, small-footprint database based on the Oracle Database 10g Release 2 code base that’s free to develop, deploy, and distribute; fast to download; and simple to administer….”

CentOS – “is an Enterprise-class Linux Distribution derived from sources freely provided to the public by a prominent North American Enterprise Linux vendor.” CentOS conforms fully with the upstream vendors redistribution policy and aims to be 100% binary compatible. (CentOS mainly changes packages to remove upstream vendor branding and artwork.)  CentOS is free.

The installation is so simple, here is the executive summary:

  1. Download the rpm format of Oracle XE (Universal) from Oracle web site
  2. Run cksum to verify the checksum figure (cksum 2403796334)
  3. Issue the command: rpm -Uvh oracle-xe-univ-10.2.0.1-1.0.i386.rpm
  4. Run ‘oracle-xe configure’ to configure the database

Below are some screen layouts captured from the installation.

[root@gl818 /tmp]# cksum oracle-xe-univ-10.2.0.1-1.0.i386.rpm (step 2)

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:
