Controlling access to data and features

Server User Guides > Interviewer - Server > Participants > 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 go to Servers > your server name > SampleManagements > your UNICOM Intelligence Interviewer Server - Admin project name > Queueing > Queues > Properties.

3 Click Add > Property.

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.

To control access to features

You can control access to the various features in Participants by assigning users or roles to Participants’ activity features. The activity features that you can use are shown in this table:

Activity feature name	Description
Can advanced edit participants	Whether the advanced option can be used for selecting and updating records on the View tab.
Can create databases	Whether a new database can be created on the Upload tab.
Can delete participants	Whether participant records can be deleted on the View tab.
Can download participants	Whether participant records can be downloaded on the View tab.
Can edit participants	Whether participant records can be edited on the View tab.
Can upload participants	Whether the Upload, Required Fields, and Additional Fields tabs are visible.
Can view participants	Whether the View and View Settings tabs are visible.
Can view summary	Whether the Summary tab is visible.

By default, the CATISupervisor role is assigned to all the activity features shown above apart from “Can advanced edit participants”, “Can create databases”, and “Can delete participants”.
