Oracle's proposed acquisition of Sun Microsystems has hit a snag, with the European Commission now launching an investigation into the $7,4-billion deal.


The news comes a couple of weeks after the acquisition was approved by US authorities.
The European Commission says it's concerned that, if Sun is bought by Oracle, it will inhibit the growth of MySQL, Sun's free database software.
The European regulators warn that the acquisition could hamper development of MySQL, which is the most widely used corporate database software in the world – and it competes with software produced by Oracle.
The Commission says that preserving access to open source software is vital, especially as many economies are emerging from a recession.
