I did a check through the current source and couldn't find out, either. My
guess would be that the V4 prefix is only relevant to v4 servers, while the
ANY prefix is relevant to IB5, IB6 and Fb1.

And that is a good question.

Not that I have seen. However, someone could write one. You would need to
isc_service_query to read isc_info_svc_get_config, which will retrieve the
values in IBCONFIG. I'm not sure whether you can update the config file via
the services api.

That is another good question. I think you may need to test this on a case
case basis. For instance, if you set the TMP_DIRECTORY via ibconfig, and the
directory doesn't exist, I don't think you will get an error. The server
just use whatever it can find (depending upon the TMP/TEMP var of the OS).

This is an area that could do with some improvement. Except, of course, that
the params are so few and the need to change them is so rare, that I do not
think it is of high priority for many people.

Database cache pages aside, I'd leave them alone. Heck, I'd leave that alone
too - it is server wide and you may not want to open _every_database with
same number of pages.
