Failed to enhance dynamic type

Hi, We are trying to enhance a class with OSGI Weaver using the JEnhancer.THIS instance as a class transformer.

So, where is this file stored??? Also, the contents of the DB don't seem to be persisted between AppServer restarts.  ... but i find  log folder in the path defined for objectdb.home but  the ...

Improvement in replication

Hi, I was thinking about some improvement in replication mechanism. Our application do only few writes (mostly reads), but those writes are important for us - objects rating, profile modifications. So in current implementation when master node dies, there is only a chance to read data from slave and all writes fails. ... is to choose the one with higher "transaction" or "log" number. What do you guys think about this? ...
