> I need to perform real time database replication from one server to another server on different Events on the server's Database, however I am new to Firebird and Jaybird, so I am not sure if it is feasible with Firebird only or I would be needing any third party tool for that, or should I consider Java for database replication or if I can write some triggers or procedures on Firebird to do that. Requirement is to update real time data from one server to another using Server push.

At the moment there is no possibility to have "server push" with
Firebird. Neither stored procedures nor something in Java will allow you
to push changes to another DB. OK, it is possible to create some UDFs
that would open connection to another database and execute some
statements, but there is no transactional control over this beast - if
you rollback your master transaction, changes are still committed in slave.

You can consider some replication software like Daffodil Replicator
(should work with Firebird/Jaybird combo) or Sequoia clustering
technology (former C-JDBC). Latter gives you transactional safety -
changes either are written into both DBs or are not written at all.
