Free Oracle Database 10g Express Edition

Looks like Oracle is feeling the pressure from the free DBs like Postgres and MySQL.

From the Oracle webpage: 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.

Link.

Looks like the maximum DB size is 4GB and it uses only one processor and at most one GB RAM.

Having a free Oracle DB is good for the projects where one is forced to use an Oracle DB.

Exporting a MySQL-table to .csv

Useful to know:

 SELECT a, b, INTO OUTFILE '/tmp/result.text' FIELDS TERMINATED BY ','
 OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\n' FROM test_table;

How to bypass the version-checker on Linux for Oracle 10g

I found this most useful post by Jonathan Gennick on FreeLists

 I haven't tried it myself, but Wim Coekaerts once mentioned
 an "-ignoreSysPrereqs" installer option that would get you
 past that Linux distribution check.

Or suggested by DJ: edit the oraparam.ini file and edit the supported versions section.

Or: run

 runInstaller --help

and actually read it :-)

Jolly good Oracle & Linux page by Werner Puschitz. There are several instructions on installing Oracle 9 and 10 on a range of different Linux versions.

The Real Point of Oracle10g Manageability

Curt Monash has written a very good article about Oracle 10g. The article argues that the real focus is on manageability, which makes perfect strategic sense. TCO (Total Cost of Ownership) is king. And with hardware getting cheaper, software getting cheaper, and custom programming being outsourced to cheap countries, administrative costs are an ever bigger part of TCO. Whats more, manageability is historically a major competitive challenge for Oracle; 10g is designed to neutralize that issue.

Installing Oracle 10g On Debian

We go through, step-by-step, the process of installing Oracle 10g Release 1 (10.1.0.2) Enterprise/Standard Edition for Linux x86 on a Debian unstable installation as of 2004-06-04. This chapter was originally written by Damien McAullay with suggestions from Giuseppe Sacco and Oliver Bankel. link
