3.6 DECdfs
This section contains release notes pertaining to Compaq DECdfs for OpenVMS
(formerly named DECdfs).
3.6.1 Version 2.3-1 Required for OpenVMS Alpha and VAX
V7.3
If you want to run Compaq DECdfs for OpenVMS on OpenVMS Alpha Version
7.3, you must install Version 2.3-1. If you install earlier versions of DECdfs
on OpenVMS Alpha Version 7.3, your system will fail. Compaq DECdfs for
OpenVMS Version 2.3-1 ships with OpenVMS Version 7.3.
Compaq DECdfs for OpenVMS Version 2.3-1 is also recommended for OpenVMS
VAX Version 7.3 systems. Earlier versions of DECdfs for OpenVMS might cause
your OpenVMS VAX system to fail, causing DECdfs to function with limited
capacity.
3.6.2 Version 2.3-1 Recommended for Systems Running Compaq DECnet-Plus
for OpenVMS
V7.3
Compaq DECdfs Version 2.3-1 contains corrections for a number of connection-
related issues when running on a system with DECnet-Plus — particularly on
systems with multiple network circuits. Therefore, Compaq DECdfs Version
2.3-1 is highly recommended for any supported system running DECnet/OSI or
DECnet-Plus.
In addition, Compaq DECdfs Version 2.3-1 adds support for DECnet-over-IP
connections. For more information, please refer to the release notes left in
SYS$HELP by the product installation.
