<p>
The database can be used from Microsoft .NET even without using Java, by using IKVM.NET:
</p>
<ul><li>Install the .NET Framework from <a href="http://www.microsoft.com">Microsoft</a>.
Mono has not yet been tested.
</li><li>Install <a href="http://www.ikvm.net">IKVM.NET</a>.
</li><li>Copy the h2.jar file to ikvm/bin
</li><li>Run the H2 Console using:
<code>ikvm -jar h2.jar</code>
</li><li>Convert the H2 Console to an .exe file using:
<code>ikvmc -target:winexe h2.jar</code>.
You may ignore the warnings.
</li><li>Create a .dll file using (change the version accordingly):
<code>ikvmc.exe -target:library -version:1.0.68.0 h2.jar</code>
</li></ul>
<p>
If you want your C# application use H2, you need to add the h2.dll and the
IKVM.OpenJDK.ClassLibrary.dll to your C# solution. See also the short

</li><li><b>ChangePassword</b> allows to change the file password of a database.
</li><li><b>Console</b> starts the browser based H2 Console.
</li><li><b>ConvertTraceFile</b> converts a .trace.db file to a Java application and SQL script.
</li><li><b>CreateCluster</b> creates a cluster from a standalone database.
</li><li><b>DeleteDbFiles</b> deletes all files belonging to a database.

For many databases, opening a connection is slow, and it is a good idea to use a connection pool
to re-use connections. For H2 however opening a connection usually is fast if the database is already
open. Using a connection pool manager for H2 actually slows down the process a bit, except if
file encryption is used (in this case opening a connection is about half as fast are using
a connection pool). A simple connection pool is:

MiniConnectionPoolManager
Hi,
Thanks a lot for your help! I can now also reproduce this problem. It only happens when using LOG=2,
and deleting or updating all rows of a table. There is a workaround (beside not using LOG=1):
System.setProperty("h2.reuseSpaceQuickly", "false");
or java -Dh2.reuseSpaceQuickly=false
I will fix this for the next release.
Regards,
Thomas

History:
A first (experimental) implementation of a Shell tools is now included (org.h2.tools.Shell).
A new Shell tools is now included (org.h2.tools.Shell) query a
database from the command line.
Performance was very slow when using LOG=2 and deleting or
updating all rows of a table in a loop. Fixed.
ALTER TABLE or CREATE TABLE now support parameters for the password field.

an in-memory table because this caused memory problems in some cases.
It was possible to create a role with the name as an existing user

The recovery tool didn't work correctly for tables without rows.
Roadmap:
SET LOG_SYSTEM {NATIVE|LOG4J|COMMONS|DRIVER_MANAGER}
Fluent API for tools: Server.createTcpServer().setPort(9081).setPassword(password).start();
console features:
- reset?
- use StringBuffer to append (copy and paste problems)
- password mask option
- result set: two modes (list and table)
- Show Tables of MySQL and Show Fields (also ij)
