Oracle's Ellison talks up 'ungodly speeds' of in-memory database. SAP: *Cough* Hana

Re: Ellison found the hot water again...

just to clear some points:

until Oracle bought SUN (in late 2009), they only tried to convince their customers (and themselves) that TimesTen will be integrated into OraDB v10x, then it slipped to v11x, but obviously they fail. After the SUN acquisition it was clear that TimesTen will be a separate product bundled with a SUN hw. TimesTen before 2008 was only be able to use table cache methods and being so, it wasn't a real in-memory DB .

Anyway, TimesTen is a completely different product and uses a completely different engine than Oracle's mainstream database engines (10,11,12...).

SAP (well, it was Sybase before SAP bought them in 2010) announced ASE v15.1 in-memory option in 2006 which is the completely same product as their mainstream database. in ASE 15.1 you can simply select device:memory instead of device:disk in case you have enough RAM in your server.

Solid Technology was acquired by IBM in late 2007 but they offered their SolidDB v3 (which is a true in-memory DB) since 2003, and as of today have already over 3million deployments.
