Oracle has axed all development efforts around Intel's Itanium, leaving HP as the last major server maker still supporting this 64-bit server chip.
Oracle said it was no longer confident about Intel's commitment to the platform, which Intel co-developed with HP and first released a decade ago.
"After multiple conversations with Intel senior management Oracle has decided to discontinue all software development on the Intel Itanium microprocessor," Oracle said in a statement. "Intel management has made it clear that their strategic focus is on their x86 microprocessor and that Itanium was nearing the end of its life."
Intel disputed the statement, and said it remains committed to the Itanium platform, which has been beset by production delays ever since it first debuted in 2001.
