But with the attacks threatening to harm the economy, the company said today that new-license revenues this quarter may decline more sharply than expected, as much as 15 percent from last year. The company said it expected an increase in sales to the federal government and law enforcement agencies, but a drop in sales to other customers. ''What impact it's going to have on the economy is very difficult to predict,'' Jeff Henley, the chief financial officer, said in an interview, referring to the attacks. ''We're still digesting what's going on out there.'' Shares of Oracle fell 45 cents, or 4 percent, to close at $11.01 ahead of the earnings call, amid a broad sell-off. The stock outperformed the Nasdaq, which lost nearly 7 percent. Oracle shares rose to $11.10 in after- hours trading. The Oracle executives commented on the financial results of their fiscal first quarter, which ended Aug. 31, for the first time since releasing them with no explanation last Thursday.
