Title: RE: [Hsqldb-developers] HSQLDB 1.8.0.4 Released

Andrew:

The "change" only effects you if for some reason you want to defer
to the client(s) to control the database instance list
(which could be a requirement if the server side doesn't know the
database instances, or if they are created after Server startup).
If the Server knows about the DB instances at startup time, the
traditional setup would probably be more simple (and errors could
be caught earlier, etc.).

You could serve multiple databases with one server before. The new feature
allows you to open the databases remotely. Re the advantage / disadvantage
of multiple databases vs single database, it is hard to tell.

Fred - currently we launch 2 or 3 databases in server mode - each server
dedicated to its own db file.   Does this mean we could potentially launch
just one process and specify in connections the target db files to be opened
(cached mode) ?   Is there advantage / disadvantage?   I'm thinking that
even if I boost the memory allocation to the one process I may gain certain
efficiencies and lower my overall system requirements with this new feature?

This is the latest bug-fix update to 1.8.0. All reported bugs have been
fixed in this update. There is also a change to the way the .properties file

is saved, avoiding deletion of this file when database and system shutdown
coincide. Details in changelist_1_8_0.txt file

An enhancement to Server and WebServer has also been incorporated. This
feature is enabled by setting a server property that allows the server to
start without any databases, while subsequent connections to the server that

include a database file:, mem: or res: URL can open the database on the
server side.

Development of 1.8.1 is moving and the current version in the CVS
hsqldb-dev3 directory is very stable. New features are regularly being added

and the alpha release is scheduled for May or early June.
