| Aquarium Database |
| Fred Fish Disks 521 - 530 |
|_______________________________________________________________|
What have we got here?
This distribution will completely replace your present Aquarium Database,
simultaneously bringing it up to date through disk 530. The database is in
a packed format, altered so by Ian Nicholl's AquaPack program. This means
that Aquarium will be usable through disk 600, perhaps even beyond that.
I will be releasing further updates to the database as Fish disks are
released. These will include instructions on how to join the updates to
your existing database.
NOTE: I am not the author of Aquarium; I have no source.
The author of Aquarium is B Lennart Olsson.
Patching Aquarium
ATTENTION: I provide this patch as a matter of extending the lifespan
of Aquarium for users without harddisks until a more permanent
solution can be found. I can take no responsibility for problems of
any kind that arise from applying this patch.
I am also unsure if B Lennart Olsson would approve of altering
his program. I certainly failed to get permission. Don't hit me!
ATTENTION: This patch will not help you unless you have two floppy
drives (or more). Aquarium keeps the data, index, and names
files open during its operation. If you have only one floppy
drive, you'd quickly go insane swapping disks ...
WARNING: Make these modifications on a COPY OF THE AQUARIUM PROGRAM.
Don't say I didn't warn you!!
Ok, down to business:
Luckily, Aquarium stores a full relative path to all its data
files, and we can modify these so long as we don't use up any more
space than already taken (this is a safety measure).
Using NewZap, you will find that Aquarium is 97 "sectors" long.
Each sector is 512 bytes. On sector 93, you will find a sequence of
bytes similar to the following rather inaccurate representation:
ASQ CNPTNF data/index data/data data/names data/keynames
It appears that the string "CNPTNF" is unique up to that point, so you
can use that to locate this region within the executable. There is
another area within the executable which has names such as
"data/names" etc. That area has a lot of "r+" symbols mixed in with
the file names. Leave that region alone; it is not the one we want.
What we need to pay attention to are the names of the four data files:
data/index
data/data
data/names
data/keynames
We will change ONLY THE "data/" portion of these, making them either
"FSH1:" or "FSH2:"
FSH1:index
FSH2:data
FSH1:names
FSH1:keynames
Notice that ONLY the file "data" will be stored on FSH2: because that
one is the biggest file and will reside by itself on an otherwise
blank disk.
Make sure you tell NewZap to SAVE the modifications! Exit the program.
You will now have to prepare two new floppy disks. Label them FSH1
and FSH2 (use the relabel command or rename blank (freshly formatted)
disks from the Workbench). Make sure there is no Trashcan folder on
the disk.
Store the file "data" on FSH2
Store the other files (even the Aquarium executable) on FSH1
Notice that you do NOT want to store the files in subdirectories any
longer. Store the files in the root of the respective volume. You
need no data/ directory any more since we patched Aquarium to use a
logical volume name instead.
Now, when you run Aquarium (from FSH1) Intuition will ask you to insert
volume FSH2 or FSH1 as required.
The Aquarium rewrite
Many of you have sent me email with suggestions on splitting the
database into two autonomous entities, and adjusting the index, etc.
Your suggestions were much appreciated, and I am glad for the feedback
from so many of you.
Unfortunately, I tend to be a bit of a perfectionist, which is
why a rewrite of Aquarium is in the planning stages and will soon be
under way. It will take some time, as I have a life to live, too, and
so, I expect, does Kyle Saunders. It seems that with Ian's help we
have a little breathing room again.
Rest assured that the Usenet community will be informed when
the time is ripe.
Many Thanks ...
I'd like to thank Fred Fish for his continuing efforts to provide us, the
Amiga community, with an organized collection of freely distributable
software. 530 Disks!!! Amazing! Go Fred, Go!
I would also like to express my thanks to B. Lennart Olsson, who made
available to us the Aquarium (Aqvarium?) for all those Fish Disks! Beats
the h*** out of searching huge text files!
Ian Nicholls of Australia, savior of time and space :-), receives my
special thanks for the aqua* utilities.
And last, but not least, all those who write all that freely distributable
software deserve our special thanks. Where would we all be without YOU?
