IBM is responsible for hardware sales, while Oracle is responsible for Oracle software sales, according to Frank Monez, Linux initiative manager for IBM System z.
Candidate workloads for the Linux on System z include Oracle database software and other Oracle software including, EBusiness Suite for Linux on System z, Peoplesoft on Linux for System z, and Siebel on Linux for System z.
IDC thinks highly of the pact, too, noting in a recent research report that the deal may well serve as "a foundation for future enterprise Linux deployments on the mainframe."
Though IBM is happy to get Oracle applications running on Linux for IBM mainframes, it isn't about to abandon its existing Linux partners.
"The co-marketing agreement does not include Unbreakable Linux," Monez told internetnews.com.com. "We continue to collaborate with and support Novell and Red Hat."
The co-marketing agreement also does not include Oracle's new Linux management offering.
Though the co-marketing agreement between Oracle and IBM doesn't include Unbreakable Linux, that's not to say IBM customers aren't asking about it.
According to Robert Shimp, vice president of technology marketing at Oracle, "some customers have expressed interest in an Oracle Unbreakable Linux support offering on IBM System z Linux."
Oracle began offering Unbreakable Linux support in October as an affront to Linux leader Red Hat. Prospective users have been able to demo the offering for free so far, though the free promotion ends Jan. 31.
