Online Lookup

This pattern provides direct interaction between the data requester (workflow client) and the enterprise information system (EIS), supplying real-time EIS data rather than cached data.

While the server notification and cached data patterns are flexible regarding MBO definition and cache group policy, the online lookup pattern must have at least one findByParameter and use the Online cache group policy:

The workflow client requests data using the findByParameter object query.
Since the MBO associated with the object query is in a cache group that uses an Online policy, Unwired Server retrieves the requested data directly from the EIS and not the cache.
Online data is returned to the client.

In this example, online data retrieval by the workflow client is triggered when the user selects the Submit menu item that calls the findByParameter object query.

Implementing Online Lookup for Workflow Clients
Define an MBO with at least one load argument that maps to a propagate-to attribute, add the MBO to a cache group that uses an Online policy, then define the workflow application that calls the findByParameter object query to return real-time results from the EIS.
