How can I synchronize DBs from multiple openCRX instances?
Depending on your DBMS (see also which DBMS should I use with openCRX) there are typically advanced (but DB-specific) tools available. For example, MySQL supports replication out of the box: http://dev.mysql.com/doc/refman/5.0/en/replication.html For a more generic overview of DBMS neutral tools, have a look at http://en.wikipedia.org/wiki/Multi-master_replication. A Java-based tool is available from http://symmetricds.sourceforge.
