Signsoft intelliBO relies on an enhanced cache system based upon the open standard X/OPEN XA.
Beside the JDO specification compliant local "PersistenceManager Cache" (also called "PM Cache" or "Local Cache"), a Signsoft intelliBO PersistenceManager can share its data among other PersistenceManager s within the same Java Virtual Machine. This is called "Intra-PersistenceManager-Cache" or "Shared Cache". The scope for this Shared Cache can be switched between Virtual Machine or PersistenceManagerFactory scope.
Additionally, the Shared Cache can be configured sharing its objects among other computers and Virtual Machines across the network, namely called "Distributed Shared Cache".
The Shared Cache works non-transactional, which means that objects used by a transaction cannot be used by another, until it is commited or rolled back.
The following picture illustrates the Signsoft intelliBO Cache System:
