Cambridge, Massachusetts-based Clam Associates Inc has its first high-availability cluster information service-program for client machines. C1 Watch, which sits on a personal computer client running Windows 3.1, informs users if a fault or system failure occurs, so they – or the applications – can take action. The product essentially tracks cluster, node and interface status, and notifies the client of any changes in the cluster topology. It is targeted at commercial organisations that process real-time data and transactions, and need their users to be connected to an IBM Corp RS/6000 database server, running high-availability cluster multiprocessing software, at all times. C1 Watch is $100 per licence; licences for up to 100 clients cost $5,000.
