In SAS^® Enterprise Miner™ Client, when you select the Decision Tree node Interactive property, the following error might occur:

Unable to open Interactive Decision Tree. Please make sure you have run the predecessors to this node and update the path.

An error similar to the following is displayed in the web application server log:

com.sas.svcs.workspace.client.GeneralServiceExceptionHolder: This server does not allow clients to reconnect after disconnecting.

The problem occurs if the SAS^® Management Console "Allow clients to reconnect" property is not selected.

To verify that the property is selected, follow these steps:

1. Log on to SAS Management Console using the SAS administrator account.
2. Navigate to Plugins ► Server Manager ► SASApp. Click Logical Workspace Server.
3. Select the server. Right-click and select Properties. Click the Options tab. On that tab, select Advanced Options (on the bottom right-hand side). If you have multiple workspace servers, then make sure that you are looking at the workspace server that is used by SAS Enterprise Miner.
4. In the Advanced Options window, click the Client Reconnection tab. Check to see whether the "Allow clients to reconnect" property is selected.

If the "Allow clients to reconnect" property is not selected, then perform these steps to select it:

1. Close SAS Enterprise Miner Clients.
2. Stop the object spawner.
3. Log on to SAS Management Console.
4. Navigate to Plugins ► Server Manager ► SASApp. Click Logical Workspace Server.
5. Select the server. Right-click and select Properties. Click the Options tab. On the bottom right-hand side, click Advanced Options.
6. In the Advanced Options window, click the Client Reconnection tab. Select Allow clients to reconnect. Accept the default time-out value. Click OK to save the selection.
7. Start the object spawner.
8. Start SAS Enterprise Miner Client, and test the Decision Tree node Interactive property.
