TIBCO BusinessEvents® Enterprise Edition 6.3.1

# Schema Model Migration with Shared Nothing Persistence

Using Shared Nothing persistence to migrate a schema model.

You can choose one of these options:

- Deploy the new EAR with the additional field and restart all nodes. The system automatically alters the space as needed during recovery.
- If it is not desired to restart the cache nodes, shut down all inference engines. Connect with the TIBCO ActiveSpaces administrator and alter the space to add new fields as shown in the example below. For details on the `alter space` command, see TIBCO ActiveSpaces version 2.x Documentation.

  The new field must be nullable as is the case for all user fields in BusinessEvents.

      alter space name"dist-unlimited-bs-readOnly-Test--be_gen_Concepts_Simple" add (field name "long_field" type 'LONG' nullable true)
      alter space name"dist-unlimited-bs-readOnly-Test--be_gen_Concepts_Simple" add (field name "con_cept_array" type 'BLOB' nullable true)

  Then start the inference engines.

- Hot deployment of new properties for Shared Nothing persistence has been added.

Note: Adding a concept property of type `contained concept` with the contained concept type set to an existing concept is supported only for the options above.

## Hot Deployment of New Properties

Hot deployment of new properties into existing TIBCO BusinessEvents concepts is available only in these cases:

- When the cache Object Management is enabled with no persistence or Shared Nothing persistence
- When the concepts with new properties are cache-only
