Zen-Nippon Shokuhin Co., Ltd , which administers Zen Nishoku Chain of super markets in Japan has selected Solaris Cluster to support an Oracle 10g database with Real Application Clusters running on E6900 systems and Solaris 10 OS. The customer has moved from a main frame based solution to one based on less expensive open architecture. For more details, you can visit http://www.sun.com/customers/index.xml?c=zen_nippon.xml.
The combination of Solaris 10 OS, Solaris Cluster and StorageTek QFS provides best of the breed performance and reliability for Oracle RAC deployments and is a good alternative to migrate from existing proprietary hardware/OS at reduced cost.
Equally important is that all the produces are open sourced! For details on the open source release of the Solaris Cluster software, visit the Open HA Cluster community at opensolaris.org.
