The European Commission has temporarily stopped its antitrust investigation into Oracle's bid to buy rival Peoplesoft because it is seeking more information from Oracle.
A decision on the proposed buy was expected on 11 May but no new deadline has been set to replace it.
The EC has requested information on Oracle's market position in human resources and financial management software.
"We can confirm that we have received the request from the European Commission for additional information on our proposed transaction for PeopleSoft. We will continue to co-operate with the commission and will respond as quickly as possible," said Oracle's vice-president of corporate communications Jim Finn.
The commission previously suspended its in-depth investigation of the proposed takeover in January to gather more information about the deal from Oracle. The commission was originally due to conclude its probe of the proposed merger by 30 March.
