Introduction to TIBCO ActiveSpaces Applications

ActiveSpaces applications are programs that use ActiveSpaces software to work collaboratively over a shared data grid. The data grid comprises one or more tuple spaces.

ActiveSpaces automatically redistributes tuples when seeders join and leave the space. Unlike a horizontally partitioned database, where the allocation of items to nodes is fixed, and can only be changed through manual reconfiguration, ActiveSpaces data is automatically updated on all devices on the data grid and rebalanced transparently by using a minimal redistribution algorithm.

ActiveSpaces allows the distribution of data replicates on different peers for fault tolerance. The data access optimization feature of ActiveSpaces uses a replicate if one is locally available. If a seeder suddenly fails, the replicate is immediately promoted to seeder, and the new seeder creates new replicates. This optimizes system performance.
