Have you examined those files in your different installations and found
them meaningfully different?

AB Installations
Hi Bob,
How about Broker.Sectors and Broker.Industries
Broker.Params ... these are all in the program directory ... do they not
cause interference when only one installation is used for all databases, since every
instance will have to start at same database and then be shifted to another one
(if so desired).
Also another point came up ... Is there an
advantage, either way, for access to CPU capacity?
In a multithreaded CPU, AB is allowed a maximum of
50% of CPU capacity.
Can a second instance of same installation
access the other 50% of CPU capacity as well as a separate installation??? or
are both limited to same 50% ???

Ara,
The DB-specific info is in broker.layout, broker.master,
broker.watch, and broker.workspace.
All four reside in the
individual DBs.

Graham,
Thanks for the detailed note
below...
I read through the section
on broker.* files and what they contain.
There seems to be a fair
amount of potential for interference between instances from same installation
depending on how one uses the system. For my purposes having one set
of Broker.* files would mess things up ... so I have to stick to
multiple installations.
With TJ solution of
disabling autosave, things should be OK, but I do hope he modifies the autosave
as it is a very good feature to have.

Installations
I have many databases for
different markets and timeframes and have always run 2 instances during the
trading day, intraday and end of day databases. Plus I often move to different
databases as I do work on different AFL.
I did use 2 installations a
long time ago but have found one installation running multiple instances is
easier and better.
I have occasionally run afoul of the layouts not being saved properly, but
to be honest this is such a small inconvenience to re-insert any AFL charts
that you added before.
Recent changes occuring make the saving of layouts better from memory as they
will auot save to your named layout when exiting that database, correct me if I
am worng.
I would say I am a far
heavier user the the majority of users as my work of writing AFL takes me to
many different exchanges and time bases ( some of these are end of day and
intraday of ASX, US, forex and futures exchanges) I keep all of these in separate
databses so that I can concentrate on using the data rather than worrying over
same symbols overwriting. I also have many different layouts for each database
to isolate the various jobs I do as I do not want 100's of sheets for each
window finding 10 to be more than sufficient for organising the charts.
I say all this to just point
out that a single installation works well with very minor inconveniences.
I would also point out that
you get into the habit of saving your layouts as named layouts, and like all
software get into the habit of saving these as you make changes. They can
easily then be brought back to the living display as required.

Two in the same boot partition interact as badly as
two instances [due to shared registry settings].

Graham,
I would prefer to have a single installation and use
it with multple data bases as you suggest... however I ran into
problems earlier doing that. That was some time ago that I had to switch
to multiple databases... perhaps before certain changes were made that make the
operation of a single installation using multiple instances practiclal.
I know that many changes have been made over time to
the preferences and parameters controlling each data base setting have been
moved to the individual data base. The problem earlier was that parameters
relating to databases were common and part of preferences, thus all databases
had one set of parameters (such as number of bars)... which was a pain...
Also I beleive that even with current version, a
single installation would have a single set of symbols. Broker files reflecting
a unique set of setting for a particular application (EOD, Real Time etc). Is
that nor correct?
Do you (or anyone else) currently use a single
installation with multiple instances without any complications???
Thanks

Why do you need multiple
installations of AB on one computer
You can just have the one
installation and use different databases. AB can be opened many times from one
installation and have separate database for each occurence.

Either do not use multiple

Installations
I am having problems with multpile installations
getting mixed up.
When I open one installation, I find the layout from
another installation have been copied into it.
Example:
1. Open Tick data base and see layouts from Time (1
min) or EOD data base.
2. I run scripts via OLE on EOD data base, and
results show up in RT installation.
How can we keep these from crossing over?
(I think there was a recent related discussion, but
can not find it)
