Unsupported Features
NonStop systems 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 each cell to provide
continuous 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 RPC IDL compiler (idl) does not include the following features:
•
The OSS C preprocessor cannot be used by the idl compiler. The
cpp_cmd and cpp_opt options of the idl compiler are disabled. The idl
compiler behaves as if no_cpp is always specified.
•
The [string] construct is not supported for a structure containing an odd
number of byte fields.
•
NonStop DCE does not support these CDS capabilities:
°
The X/Open directory service (XDS) API and the X/Open object management
(XOM) API
°
Global directory service (GDS) and global directory agent (GDA/X.500)
°
Hierarchical cells
°
The CDS browser
°
Cell backup for administrative purposes
•
NonStop DCE DTS does not provide:
°
The network time protocol (NTP) time provider.
°
Time inaccuracy when retrieving the system time. Both utc_gettime() and
utc_getusertime() always return the inaccuracy as infinite.
•
NonStop DCE threads do not support:
°
Preemptive scheduling
•
The preemptive thread scheduling policies are not supported. Only first-in,
first-out (FIFO) scheduling is supported. Once scheduled, a thread
executes until it blocks.
