The Question is: Dear Sir, I have 2 Axp Boxes 2100 running Open VMS 7.1 so I would like to make each box to be backup to each other by automatically if one box fail. My question is Does DEC have any software to help me on this or Can polycenter do this ? If yes can I write my own application to talk with that software ? Regards Wichaya The Answer is : Please take a look at the features and benefits of an OpenVMS Cluster. You can use the capabilities of a cluster to balance the load across the available systems, to share some or all files, to fully share all system authorization data, to share queues and such, and to share all application and user configuration information. OpenVMS Cluster configurations support network mechanisms (LAT and DECnet) that allow requests and operations to be (transparently) routed to the best available system, and (transparently) routed to the remaining system (automatically) in the event of a system failure. An OpenVMS Cluster configuration also means you can have a single system disk -- possibly using host- or controller-based volume shadowing for storage hardware redundancy. The OpenVMS Cluster interfaces and mechanisms are completely transparent. Applications can also specifically take advantage of available techniques that make better use of a cluster configuration -- such as using the lock manager to establish a "primary" and multiple "secondary" applications across the nodes in the cluster, and automatic "election" of a new primary application in the event of node or application failure. These same techniques and interfaces also operate as expected in a standalone system environment. For remote management, look at the OpenVMS Management Tools, at the remote display capabilities of DECwindows, at DECamds, and other tools. (You likely already have licenses and kits for these packages.) The upper-end NAS licenses include an OpenVMS Cluster license, and the cluster license is also available seperately. (You will need a full Cluster license -- not a "client" license -- for this configuration.)
