edmiRemoteShrinkDatabase is an extension edmiRemoteOpenDatabase. This means that the database must be closed when edmiRemoteShrinkDatabase is called. The database is opened when edmiRemoteShrinkDatabase is finished. Later there will be implemented an option saying that the database shall be left closed after edmiRemoteShrinkDatabase is called .
