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.
