VM/ESA DCE Feature
NOTE: DCE feature is not available with z/VM V4 or V5 or later.
VM/ESA Version 2.1 DCE Feature * Generally Available (Feb. 23, 1996)
VM/ESA* Version 2 was made generally available on October 27, 1995
providing portability of applications and data with VM support
of selected POSIX** standards. Customer acceptance of this new version
has been occurring at a record pace, as is evidenced by the number of
migrations to date from previous levels of VM.
VM/ESA Version 2 support for OpenExtensions* is enhanced even
more with the general availability of the Distributed Computing
Environment (DCE)*** feature to more fully exploit open distributed
client/server computing for VM/ESA customers.
VM applications can now interoperate with other DCE-compliant
systems in a DCE cell using the VM DCE services. Support consists of
the following:
-
Client support for the DCE Cell Directory Server providing more
transparent access to applications and data
-
Client support for the DCE Security Server permitting a set of common
security services across different systems and applications
-
Support for Remote Procedure Call (RPC) allowing development of
client/server applications without the programmer needing to get
hung up in communications details
-
Support for DCE Threads easing the portability of DCE-compliant
applications
In addition, support for the privacy of user data using RPC
is also available with the DCE User Data Privacy Feature.
Availability of this feature varies by country.
Both DCE features were available at no cost to VM/ESA Version 2
customers.
Further information was made available
in announcement letter 295-240, dated June 12, 1995.
