Unsupported Features
•
Virtual hosts
A virtual host is a NonStop Availability feature. Each virtual host is a complete
implementation of a DCE host, with its own:
°
Copy of the TCP/IP stack, LAN input/output process (IOP), Internet Protocol
(IP) address, and IP controller
°
Hostname
°
DCE demons cdsadv, cdsclerk, cdsd, dced, secd, and so forth
NonStop nodes can be configured with any of the following:
°
One or more virtual hosts in the same DCE cell
°
Multiple virtual hosts on multiple cells
°
A single virtual host in each of multiple cells
HP recommends that at least two virtual hosts run in the same cell to provide fault-
tolerant access to DCE services.
Unsupported Features
These OSF DCE features are not supported by NonStop DCE:
•
NonStop DCE does not support these remote procedure call capabilities:

The nidl_to_idl utility is not provided.
°
The IDL compiler does not include these features:
•
The OSS C preprocessor cannot be used by the idl compiler.

The X/Open directory service (XDS) API and the X/Open object management
(XOM) API
°
GDS and GDA/X.500

Note. he distributor-agent extension is not part of the initial controlled availability release of
NonStop DCE; it will be available later.
