EBF's

Allow an EBF to install even if it is older than the current EBF. This only
need work within the same major/minor release. Specifically I would like to
be able to uninstall an EBF, and would be acceptable if this uninstall was
accomplished by re-installing the previous EBF. This is much simpler than
uninstalling and re-installing Sybase. That requires digging up the license
key, installing the release from CD, potentially installing the maintenance
release we downloaded and then installing an EBF.

The overwrite would be much simpler (and likely simple to implement)

I like the idea, but... it would probably make every EBF as large as a
full install.

Let's say EBF 1 does not need to include module A because A is not
changing. However, nobody knows if EBF 2 is going to include module A,
so EBF 1 would have to include it just so it could overwrite the one
that *might have been* installed by EBF 2.

In other words, every EBF would have to include everything... that's
not necessarily a bad thing, it might even make building an EBF easier
for iAnywhere :)

Another approach is to copy the installation folder C:\Program
Files\Sybase\SQL Anywhere 9 before installing an EBF. This works well
in practice; to roll back, one simply renames folders.

In *theory* you should do something with the stuff installed
underneath C:\Program Files\Sybase\Shared but I've never bothered
*and* I've never been hurt by it.

I guess there might also be stuff installed in Windows folders, but
once again, my ignorance has remained blissful.

ON BIG PRODUCTION SERVERS, however, I've always re-installed and
rolled forward... one can never be too paranoid. Plus it's usually a
small blip among all the OTHER CRAP that goes on when you have to roll
back. Plus it almost never happens... that's what all the testing is
for :)

Why isn't it as simple as having a pop-up dialog that says, "Are you sure
you want to apply an earlier version of the system?

When I look at EBF's they are generally the same size, because they do have
to include every module. This is because an EBF needs to include all of the
changes from the GA release to present. Luckily with Sybase, intermediate
EBF's never have to be applied when installing the most recent EBF.

FWIW the 9.0.2 upgrade was about 118M whereas subsequent EBFs have
been hovering around 70M... don't think the EBFs contain everything,
just everything that has changed since GA.

Having said that, I still agree with you... a 118M EBF would not
bother me, if it gave me the ability to *safely* roll back to an
earlier EBF.
