Operating Systems: because Frext
is running on Java, Frext runs everywhere where the specified Java
version is running on (Linux, Microsoft Windows,
OpenBSD, etc.); Frext is therefore OS-independent.
- Firebird 1.5 or higher. Frext
depends on specific features from the 1.5 version, namely transaction
id and dynamic SQL
- Java JRE 1.4 or higher.
is built upon Java so it needs the runtime engine to execute
- Jaybird 2.01
or higher. Jaybird is a Java JDBC-driver, providing access
from Java to Firebird.
Because Linux has a
case-sensitive file-system, the name of the folders where messages are
placed must be all in lower case
- Homogeneous table structures.
This means that
tables which are to be replicated must have the same structure, i.e.
same table name and field names. This can be limited to the replicated
fields only, because Frext allows you to replicate only a limited set
- No more than five key fields per table.
It is unlikely that there are more than five key fields present in one
or more tables. If so, this is surely a case of over normalization.
