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 exclusively 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 Open a command prompt, navigate to:
[INSTALL_FOLDER]\IBM\SPSS\DataCollection\<version>\Interviewer Server\Server
and then type:
RegIntSvr /u
This unregisters the interviewer session engine from the Web tier.
2 From the Start menu, run regedit and edit the LocalEngineURLs registry key at:
HKEY_LOCAL_MACHINE\Software\SPSS\mrInterview\3\Interviewing
to include only the Web engines. For example:
'http://servername/mrIEngWS3','http://servername/mrIEngWS4','http://servername/mrIEngWS5'
The Web tier should not include the default engine 'http://servername/mrIEngWS' as this will be used for telephone interviewing by default.
3 Back 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.
4 In Windows Explorer, navigate to C:\InetPub\wwwroot\SPSSMR\CatiInt and open Web.config.
5 In the <appSettings> section, change the value of the INTERVIEW_SERVER key so that it names 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.
6 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"/>
7 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.
