Oracle got into the hardware business with the acquisition of Sun Microsystems, a deal that closed in early 2010. It has been rolling out a series of specialized "engineered systems" that combine its hardware and software. These include the Exadata database machine and Exalogic application server.

The company has tried to get ISV (independent software vendor) partners on board with this one-stop-shop mindset through the Exastack certification program, which was . Under the program, ISVs certify their products for Exadata, Exalogic and the accompanying stack of software they run, which includes Oracle's database, WebLogic application server and Oracle Linux.

Exastack has two levels, Ready and Optimized. Within the past year, 100 ISV applications have gained Ready status, and another 35 have reached the Optimized level, Oracle announced Tuesday.

Partners will now also be able to gain Exastack Optimized certification for the SPARC SuperCluster T4-4, Oracle said.
