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
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.
