I don't recognize a program named dbVerify; there was a tool called
dbReadTest which came with 3.14 and matches the functionality you're
describing. However it relied on the dbStaticHost library, the
functionality for which was deleted in 3.15 (this was originally
provided for use by dbExpand and various database design tools, and
stored all field value data as strings).

We don't provide a replacement for dbReadTest at the moment. The DBD
file parsing functionality (used at build-time for converting .dbd files
into .h files) was converted into Perl modules and scripts, but there
wasn't an urgent need for parsing DB files so Perl scripts for that
haven't been included (I have some, but IIRC they can't yet parse the
new JSON field data that was added for Base-3.16.1).

You should be able to use the 3.14 version of dbReadTest with 3.15.4
IOCs but in 3.15.5 we changed the promptgroup values, so that doesn't
work any more now.

It may be possible to create another program like dbReadTest by
bastardizing the softMain.c that is part of the softIoc, but it would
have to dynamically create its own registerRecordDeviceDriver data from
the IOC's DBD file (that data is normally compiled into the IOC), and
that won't be trivial to do.

Evidently I need to finish off my Perl DB parser, but I don't think that
will make the upcoming EPICS-7 release.
