Oracle is preparing to battle US regulators in court if they move to block the company's $9.4bn takeover bid for PeopleSoft.
Oracle chief executive Officer Larry Ellison is rallying support from members of the company's board for a court fight in anticipation of a possible decision by the US Department of Justice to oppose the deal.
Earlier this week, PeopleSoft said officials from the DoJ's antitrust division recommended that the department block the proposed acquisition.
The DoJ is expected to make a final decision by 2 March.
PeopleSoft has said that the acquisition would significantly reduce competition in the enterprise software market, and has been lobbying the DoJ in its case.
Oracle plans to argue that the business software market has been too narrowly defined and players such as Microsoft have not been accounted for.
Despite the recommendation to block the buy, Oracle representatives made clear this week that they were not ready to give up on the deal.
Oracle said it believes the acquisition will eventually be approved.
