Refresh Nodes

Nodes such as Data Source node, Update Table node, and Model node rely on database resources for their definition. It may be necessary to refresh a node definition if the database resources change.

To refresh a node:

1. Click the node that you want to refresh.

2. In the right pane, go to Properties, and click the applicable section:

   • Data: For Data Source node

   • Model: For a Model node

   • Columns: For an Update Table node

3. Click the icon. Data Miner connects to the database and validates the attributes or models. The status of the attribute or model is set to either:

   • Valid: Indicated by the node without any mark on its top right corner.

   • Invalid: Indicated by the mark or mark on the top right corner of the node.

Other possible validation error scenarios include:

• Source table not present: Error message states that the source table or attribute is missing. You have the option to:

  • Select another table or replace a missing attribute.

  • Leave the node in its prior state by clicking Cancel.

• Model is invalid: Click the Model refresh button on the Properties Model tool bar to make the node valid. For Model nodes, the node becomes Invalid if a model is found to be invalid. The Model node cannot be run until the node is made Valid.

• Model is missing: If the Model node is run and the server determines that the model is missing, the node is set to Error. You can rerun the Model after the missing Model is replaced.
