Configuring Limited Cache and Object Table Cache Options

As desired, you can set the cache to limited at the default level and unlimited for specified objects; or you can set the cache to unlimited at the default level and limited for specified objects.

When the cache is limited, the number of cache objects is limit * no.of cache servers.

Procedure

  1. Select the CDD editor Cluster tabObject Management node.
  2. In the Entity Cache Size setting, enter the desired number of objects per entity type.
  3. In the Object Table Cache Size, enter the desired number of objects (handles) in the object table cache. You cannot set this value differently for different object types.
    See The Role of the Object Table in TIBCO BusinessEvents Architect’s Guide for more details about the object table.
  4. Select the Cluster tab > Domain Objects > Defaults node.
    Check the Is Cache Limited checkbox to enable limited cache globally. (Or uncheck the checkbox to use an unlimited cache globally.)
  5. Select the Domain Objects > Overrides node. Select an override entry (or add one as needed).
  6. Set the Is Cache Limited checkbox for the selected object type in one of the following ways:
    • If limited cache is set at the default level, uncheck the overrides Is Cache Limited checkbox to use an unlimited cache for objects of this type.
    • If unlimited cache is set at the default level, check the Is Cache Limited checkbox to use a limited cache for objects of this type.

      See Configuring a Limited (or Unlimited) Cache for important requirements. For reference documentation on the Is Cache Limited checkbox see CDD Cluster Tab Domain Object Default Settings.

  7. Ensure that multiple clusters do not conflict.
    With TIBCO BusinessEvents DataGrid clusters, use a different value for Cluster Name (in the Cluster tab, General node) and also use different discovery values.

    With Coherence clusters, use a different value for cluster name.
