Controlling access to data and features
You can restrict access from the Participants activity to specified servers, databases, tables, and columns by adding entries to the SampleMgtGUI.Config.xml file. For more information, see Controlling access to sample data.
Only fields that were selected on the Sample Management tab of the Launch activity when the project was activated can be viewed in the Participants activity.
To control access to data by the Sample Management system
You can specify that one or more columns in your sample table are read-only and cannot be updated by UNICOM Intelligence Interviewer’s sample management system. To do this, you need to use DPM (Distributed Property Management) Explorer as follows:
1 In Windows Explorer, run DPMExplorer.exe, which by default is in:
[INSTALL_FOLDER]\IBM\SPSS\DataCollection\<version>\DDL\Code\
Tools\VB.NET\DPM Explorer.Net
2 In the left pane, expand the top-level node (the site name) and then expand the following nodes:
Servers > <your server name> > SampleManagements > <your UNICOM Intelligence Interviewer Server - Admin project name> > Queueing > Queues > Properties
3 From the Add menu, choose Property. This opens a dialog box.
4 In Name, type ReadOnlyFieldColumns.
5 In Value, type a comma-separated list of the column names in your sample table that you want to be read-only.
6 Click OK. This adds the ReadOnlyFieldColumns property to DPM.
