Setting the Object Management Mode of a Database Concept
The term mode refers to cache object management behavior. If a cache is enabled for the project, you can set objects (either globally or individually) to use one of three modes: Cache Only, Cache + Memory, or Memory Only.
The default mode for a cache cluster is Cache Only. However the default mode of a database concept is Memory Only. See TIBCO BusinessEvents Developer’s Guide for more details about modes.
- Procedure
- In TIBCO BusinessEvents Studio, open the project CDD file for editing.
- In the Cluster tab, expand .
- Click Add. Select the database concept you want to override and click OK.
- In the tree on the left, select the
/uri
entry for the database concept and select Cache Only or Cache+Memory.Note: Cache+Memory is recommended only for constants or concepts whose values change infrequently. It is not generally appropriate for database concepts. If you select Cache+Memory, additional configuration is required. See TIBCO BusinessEvents Developer’s Guide for details. - Save the resource.
Note: Most other override properties relate to backing store. Database concepts cannot be enabled for inclusion in a backing store. Any backing store settings are ignored.
