JD Edwards stockholders received $14.74 per share in either cash, PeopleSoft stock, or a combination for each share in a deal worth a total of $1.8bn.
Michael Maples, a JD Edwards board member, will join the PeopleSoft board of directors as part of the acquisition.
PeopleSoft has been fending off a hostile takeover attempt by Oracle while it completed the JD Edwards acquisition. Oracle will stay the course, a spokesman said last week.
"We believe time is on our side. Oracle remains committed to acquiring PeopleSoft - even with the addition of JD Edwards," the company said.
PeopleSoft this week reported earnings that met its raised expectations for second-quarter revenue and net income.
