This is working quite well for us.  Here is a synopsis of how we do it.
Details are available if anyone is interested.

1) Create a journal
2) Create two journal receivers to hold the journal entries
3) Start journaling the physical files you want to mirror
4) Once a day, or however often, change journal recievers (switch between
the two)
5) Run DSPJRN to dump the journal entries to a database file.
6) Download the database file
7) Convert the entries in the database file to SQL statements(INSERT,
UPDATE, DELETE).  I have a utility for this which I can make available.
8) Run a perl script which uses DBI to execute the SQL statements.  I have
a script for this also.

The database on Linux is now synchronized with the database on the 400.
We use this for Oracle, but it should work with any database supported by
DBI.  You may also have to load the database initially.  I have utilities
to do this on Oracle.
