Hi,
You didn't tell us the database URL you use, but it looks like you use
NIO, something like jdbc:h2:nioMapped:~/test.
When using the "nioMapped:" prefix, files larger than 2 GB are not
supported currently. This is not well documented (the only place it is
documented is FileObjectDiskMapped.jav

Did you also see other error message in the .trace.db file?
Using MVCC usually solves such problems, but I wonder why you need to
use transactions that longe

Hi,
Could you run the "Recover" tool against your database and send the
result, or (even better) send or upload the database file somewhere so
I can analyze it?

I also did some more experiments playing with the lob-settings.
System.setProperty("h2.defaultMaxLengthInplaceLob", "512");
This forces the system to write the lobs dir - my messages really are
smaller then the 4k default.
The behaviour is like this:
- h2.db still grows, of course much smaller

H2 doesn't come with such a tool, but there are many tools available,

It sounds like. Could you run the "Recover" tool against your database
(when it's about 10 MB big or so) and send the result, or (even
better) send or upload the database file somewhere so I can analyze
it

Yes. There is a "Scripting Engine" (javax.script) binding for

However, the problem here is that we've got th

I don't know what the problem could be... Could you possibly debug the

Just set a breakpoint on the line "throw new

For what it's worth, I too just edit text files.
Visual tools tend to ignore things like source control, and are lousy at
doing "diffs" between versions of a single database.

I have no idea. However, with a little extra work you could set it up such that
the feature is available on 1.6 but not on earlier versions. Personally, I
wouldn't think that is unreasonable. If it is one's choice to live on legacy
software then he must accept that there are prices to pay for t

How do I get the "info" parameter if I have a JDBC url ?

I felt that what we need is just a standalone official "migrate.jar"
or a compact package of tools downloadable on the H2 website. As long
as the H2 file storage format doesn't change, then the migrate tool
would not be updated and allow cross migration between different
formats of H2 storage if ev
