Many of the increases were significant: a CPU license for its database, for example, rose from $40,000 to $47,500, more than 18 percent. In a Forrester Research report on the increases, Principal Analyst Ray Wang noted that Oracle applications previously priced at $3,995 per user jumped 15 percent to $4,595 per user. Those include such applications as: financials, HR, enterprise asset management, and inventory and order management.

With all that's going wrong with the U.S. economy, why would Oracle do this now, especially since Oracle reported strong fourth-quarter and full-year financial results in late June?

"Increases during an impending economic downturn appear illogical," Wang notes.

One of the main reasons behind the move is because of the worsening state of the U.S. dollar, and Oracle execs might see big trouble looming on the horizon. "Forrester believes that recouping for dollar devaluation is the main rationale behind the recent price shifts," writes Wang in the report. (For more on dealing with Oracle, see "How a European Bank Got Oracle to Surrender Key Software Licensing Points.")

There are two currency-related problems right now for Oracle, contends Wang. First, is that Oracle offers "one global price list" for all its products based in U.S. dollars, which Oracle makes public—a highly unusual move. (So if you're buying Oracle database technology in Europe now, you're very happy.)

"Unlike many vendors who account for global currency fluctuations with country-, region- and industry-specific uplifts, Oracle maintains consistent pricing in dollars," writes Wang. "The dramatic devaluation of the dollar has led to a de facto discount in the 30 percent to 35 percent range for multinationals that purchase in the pound sterling, the euro and, to a lesser extent, the Japanese yen. As a result, price increases mainly affect the U.S., while other euro zone countries will not see a major increase in real dollar terms."

Second, CEO Larry Ellison has challenged his company to hit 50 percent profit margins and 20 percent earnings annual growth. Much of that will come from Oracle's business application lines, like Hyperion, BEA and Siebel, which are part of Oracle's acquisition strategy.
