Oracle's decided it will support Windows 10. For its databases.
Big Red's popped out a ”Statement of Direction” (PDF) in which it says it “plans to certify Oracle Database 12c (184.108.40.206) on Windows 10 by October 2015”.
The 32-bit Oracle Database client will get the nod on the 32-bit and 64-bit versions of Windows 10. The 64-bit Oracle Database Server and Client Windows will be permitted to grace the 64-bit version of Windows 10.
Oracle “... also plans to certify the next major Oracle Database 12c release on Windows 10, when the Database release is supported for Windows operating systems.” The 32-bit version of Windows 10 won't get Uncle Larry's Good Datakeeping Seal Of Approval.
Only Windows 10 Pro and Enterprise get the certification.
There's a warning that “As Windows 10 is a client operating system, some Oracle enterprise server features, such as Real Application Clusters, are not supported.”
And fair enough too: Oracle's almost certainly doing this to ensure that developers can run its databases in the many scenarios in which it makes sense to do so. With many such users working in businesses, the October target date probably won't be much on an inconvenience: few businesses are charging towards Redmond's latest operating system. Once they do, their users can enjoy blending Oracle and Microsoft in the one PC! ®
