NonStop DCE Extensions to OSF DCE
library (UL) for the TNS/R and TNS/E versions of DCE. Both libraries interoperate at all
levels except for remote procedure call data-protection-level “packet privacy.”
DCE Security Core Services - USA supports the remote procedure call data-protection-
level “packet privacy,” which uses Data Encryption Standard (DES) to encrypt data in
remote procedure calls sent between DCE applications.
DCE Security Core Services - Export does not support the remote procedure call data-
protection-level “packet privacy.
Optional NonStop DCE components are:
NonStop DCE Extensions to OSF DCE
NonStop DCE provides two major extensions:
•
A CDS server based upon NonStop SQL/MP
The NonStop DCE CDS server is based on HP’s high-performance relational
database technology, NonStop SQL/MP, instead of the in-memory database on
which the traditional DCE CDS server is based. Through its CDS server, NonStop
DCE removes virtually all limits to the size of the CDS namespace. Moreover,
NonStop DCE treats each set of logically related updates as a single database
transaction for increased robustness and database consistency.
NonStop DCE also provides better performance. Because the implementation is
based upon NonStop SQL/MP, NonStop DCE improves concurrency by allowing
multiple writers; it takes advantage of caching in the database manager and it
eliminates the blocking checkpoint mechanism.
The NonStop DCE CDS server is fully interoperable with DCE applications and
DCE implementations on platforms other than NonStop systems.
•
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 IOP, IP address, and IP controller
°
Hostname
°
DCE demons cdsadv, cdsclerk, cdsd, dced, secd, and so forth
Note. For TNS/R programs consisting of position-independent code (PIC), if the application is
using the DCE library along with another user library, the DCE library must be relinkable.
DCE CDS Server (T8330) Enables a NonStop host machine to be configured
as a cell directory server.
DCE Security Server (T8331) Enables a NonStop host machine to be configured
as a security server.
