Setting Up Shared Nothing Persistence

Shared Nothing persistence allows you to store data at individual node level, instead of a centralized location.

Following steps explain how to configure a TIBCO BusinessEvents project to use Shared Nothing persistence:

Procedure

  1. In BusinessEvents Studio Explorer, edit the project CDD file to set the Object Management to Cache and Provider to TIBCO.
    Note: Shared nothing persistence works in the cache only mode. Any overrides for the concepts or events should also be in the cache only mode.
  2. For the Backing Store, select the Persistence Option as Shared Nothing.
  3. Enter the value for persistence path as the absolute path to the directory where data is to be stored.
  4. Select the appropriate persistence policy.
  5. Save the CDD file.

Result

When using up Shared Nothing persistence, to ensure that data is not lost when nodes leave the cluster, you must set the number of backup copies to 1 or more.

Note: The following words are reserved words and cannot be the name of a property in an event or a concept:

extid, id, closure, next, ttl, and fired.
