It is stable and reliable to me. It is easy to manage also. Oracle replication need to have primary key in tables to be able to replicate (or at least you have to know what is a primary key). I think oracle replication use internal triggers to replicate tables. Shareplex read the log file to do replication.

The mathods SharePlex uses do not give the possibility to replicate several DDL-statements such as droping a table, altering the structure of the database, etc.

SharePlex is a system for regeneration of SQL-statements.

Libelle is good.
