Hi all,

I have an application that has a connection pool opened, to a certain
database, with all connections having autocommit true; the default
behaviour. Besides this, I keep a unique connection opened to the same
database with autocommit false that I use to make changes in the
configuration. The problem here happens when I try to use the connection
with autocommit false, then I start getting exceptions like:

org.h2.jdbc.JdbcSQLException: Timeout trying to lock table "A_TABLE"; SQL
statement:
SELECT SOMETHING

No matter how much I increase the LOCK_TIMEOUT I still get these exceptions.
Using MVCC is not an option for me as this is a production database and the
application became to behave very slow.

What do you think is the problem here. Can't you keep at same time
connections opened with autocommit = true and autocommit = false?

Thanks,
Dani.
