Db2 on smaller-scale servers
In addition to the enterprise servers, most companies support smaller-scale servers on local area networks (LANs). Smaller-scale servers handle important applications that don't demand the resources that are available on the larger enterprise servers.
Db2 runs on the Linux® operating system, including Linux on IBM zSystems. The IBM zSystems platform offers four operating systems on which you can run Db2 data server products: z/OS, Linux, VM, and VSE.
Many customers use Db2 on Linux, on IBM zSystems, as their application server, connecting with Db2 for z/OS as the data server, so that they can take advantage of distributed connections and HiperSockets for fast and secure communication.
