The German Central Bank has chosen Sun Microsystems Inc as its Unix partner. The Deutsche Bundesbank, which is secretive about its Unix strategy and plans, said it will implement SAP AG’s R/3 on Sun Sparcsystems running Solaris 2. No other details were given. The choice is a welcome one for Sun, which the Bundesbank has already chosen as the hardware supplier for its shares and currency trading activities. The installation went on line at the start of the year and is based on more than 30 Sparc workstations and servers.
