HP and Oracle have put their dispute on hold for the first day of Oracle's OpenWorld consumer event.
Instead, both parties pitched their products to the customers and media in their respective speeches.
The first keynote was delivered by HP executive vice president Ann Livermore, who chose to skirt around the ongoing tiff between the two companies and gave a lengthy presentation on HP's new data centre products, which support Oracle software.
Livermore also told the people attending the keynote that HP had spent a fortune to make its hardware compatible with Oracle software.
She also said that Oracle and HP shared 140,000 customers and around 12,000 HP people spent their entire day working on Oracle software.
Ellison chose to ignore HP altogether and went straight to business by introducing Oracle's new Exalogic Elastic Cloud.
The product is a combination of advanced Oracle hardware and software, powerful and fast enough to allow Facebook to run the entire platform using just two Exalogic systems.
