Sequence Caching
There are several ID sequence caches in ActiveMatrix BPM, maintained by different components of the system.
These caches store unique identifiers for various entities within the system. When a new entity of the appropriate type is required, its ID can be assigned from the cache without needing a call to the database.
The size chosen for a cache can have an impact on system performance. For example, a cache size that is too large will take up resources unnecessarily. But if a cache size is too small, the component will need to call more frequently to the database for a new batch of identifiers.
The sizes of these caches are defined by the values assigned to properties in various BPM properties files. For more information, see the section about BPM Properties Files in the TIBCO ActiveMatrix BPM Administration guide, in particular the subsections about the Business Resource Management, Calendar, and Directory Engine properties.
