Upgrading? Beware!


Be sure to read about significant changes (although this is not exhaustive), and the revised Technical Overview and to a lesser extent the Environment Overview.

With the move from from HFRD to WASD the name and location of the document in [DOC.HFRDHYP] changed to [DOC.ENV] (apologies for any broken bookmarks!)

4.n to 4.4

Due to changes in connection request processing some NETLIB supporting TCP/IP packages can no longer provide DNS lookup (it now occurs at AST level, see the NETLIB documentation).

This version has a separate, configurable message database capable of supporting multiple, concurrent languages. A logical name, HTTPD$MSG, needs to be provided to locate it for the server. A default file may be copied from HT_ROOT:[EXAMPLE]HTTPD$MSG.CONF to wherever the site places configuration files.

The configuration directives "ErrorInfo", "ErrorSysAdmin" and "AuthVMS" have been retired, and the following introduced, "DirDescription", "DirNoPrivIgnore", "ErrorSourceInfo", "LogFormat" and "Service".

SYSUAF-authentication (previously "AuthVMS") is now controlled using the server qualifier /SYSUAF. The qualifiers /PROFILE and /SERVICE have been introduced.

Minor changes to configuration (including mapping for the echo and Xray facilities) and startup files can be checked in the HT_ROOT:[EXAMPLE] directory.

3.n to 4.n

There are some significant changes in configuration file format and server startup (as well as functional and performance improvements for that price :^)

If at all possible, restoring the new version 4 tree, reviewing the new configuration and mapping files, etc., adjusting startups, and then migrating any local applications into it, might be the cleanest approach.
