Configuring engines specifically for web or telephone interviewing
By default, all interviewer session engines are equally available for both Web and telephone interviewing. You can change this so that some interviewer session engines are used only for Web interviews and others are used only for telephone interviews. To make this change to your site, do the following on each computer running the Interview Service:
1 Logon as a user who has trusted user access to DPM. This is typically the installing or running user.
2 At the command prompt, go to the following folder:
[INSTALL_FOLDER]\IBM\SPSS\DataCollection\<version>\Interviewer Server\Server
3 Type the following command to unregister the interviewer session engine from the Web tier:
RegIntSvr /u
4 From the Start menu, run regedit, and then edit the LocalEngineURLs registry key at the following location to include only the Web engines:
HKEY_LOCAL_MACHINE\Software\SPSS\mrInterview\3\Interviewing
For example:
'http://servername/mrIEngWS3','http://<servername>/mrIEngWS4','http://servername/mrIEngWS5'
The Web tier should not include the default engine 'http://<servername>/mrIEngWS', because this is used for telephone interviewing by default.
5 At the command prompt, type RegIntSvr to register the interviewer session engine with the Web tier.
This registers the engines specified in LocalEngineURLs for Web interviewing.
6 In Windows Explorer, go to C:\InetPub\wwwroot\SPSSMR\CatiInt, and then open the Web.config file.
7 In the <appSettings> section, change the value of the INTERVIEW_SERVER key to the Interview Service computer that you want to use for telephone interviewing. For example:
<add key="INTERVIEW_SERVER" value="RedServer"/>
This will default to using the http://<servername>/mrIEngWS engine.
8 If you want to define an alternate server for telephone interviews, specify its name as the value for the ALTERNATE_INTERVIEW_ENGINES as follows:
<add key="ALTERNATE_INTERVIEW_ENGINES" value="http://<servername>/mrIEngWS2"/>
9 If you want the telephone interviewing engine to appear in the Interview Monitoring Activity report, add the engine to Clusters > Default > InterviewServers > <servername> > InterviewEngines in DPM.
This does not cause Web traffic to be sent to the engine.
