The Question is: Where and how is logical SYS$NODE defined. I have been unable to find any references in OVMS documentation, FAQ, or wizard history. The Answer is : Please review the DECnet Phase IV or DECnet-Plus documentation for details on this and on other logical names associated with DECnet. The logical name SYS$NODE is presently defined by the DECnet startup procedures. If DECnet is disabled or not installed, the logical name will not be defined. Please use f$getsyi or sys$getsyi to locate the SCSNODE or NODENAME name for the host, or use any of the various other storage mechanisms for the nodename, as the SYS$NODE, SYS$NODE_FULLNAME and various other related logical names are expressly reserved to DECnet. Any local definitions of these logical names -- outside of the logical name definitions provided by the DECnet networking package -- is not recommended and not supported. If you need your own logical name, please create it -- though again, the SYS$ facility prefix is reserved to system-related logical names. Though you could obviously attempt to create your own definition of this or of another reserved logical name, the presence of the SYS$NODE logical name might be construed by an application or a layered product as an indication of the presence of and availability of DECnet. That is clearly not the case here. (This local definiton of this logical name is unsupported and not recommended.) For an introduction to some of the many places where a node name is stored or is available for applications, please see the OpenVMS FAQ. Specifically, please see the OpenVMS FAQ section on renaming a node.
