Title: TDB Requirements
-TDB requires Java 6.
-
TDB can run on 32 bit or 64 bit JVMs. It adapts to the underlying
architecture by choosing different file access mechanisms. 64 bit
Java is preferred for large scale and production deployments. On 64

+The on-disk file format is compatible between 32 and 64 bit systems
