Adding a new interviewing server to an existing cluster

Developer Documentation Library > Interviewer - Server > Administration and maintenance > Adding a new interviewing server to an existing cluster

To add a new Interviewing Server to an existing cluster with live respondents, without disrupting the service for respondents currently taking surveys, follow these steps:

1 Go through the pre-installation checklist for the new server.

2 Make a back-up copy of DataCollectionSitePrep.ini from the original installation and also of key areas of your system such as FMRoot and [INSTALL_FOLDER]\IBM\SPSS\DataCollection\<version>\Interviewer Server\Projects.

3 Edit DataCollectionSitePrep.ini from the original installation to reflect the new servers you want to add, as follows:

Increment the value of InterviewServer as appropriate.

Add a new InterviewServern entry to the [InterviewServer] section giving the name, port, and protocol to be used for communicating with this server.

4 Double check DataCollectionSitePrep.ini to verify its accuracy.

5 Go to the mrInterviewSiteInstallation folder, and then run the installation program from there.

6 Navigate to:

[INSTALL_FOLDER]\IBM\SPSS\DataCollection\<version>\DDL\Code\Tools\VB.Net\DPMExplorer.Net

7 Double-click DPMExplorer.exe.

8 In the left frame, click Clusters.

9 In the upper right frame, click DefaultCluster.

The property's value is displayed in the lower right frame.

10 In the lower right frame, add the name of the new interviewing server to the IVServerList variable (names must be separated with semicolons) and click Apply.

11 Close DPM Explorer.

On the original interviewing server

1 Navigate to:

C:\Program Files\Common Files\IBM\SPSS\DataCollection\<version>\ProjectMgmt

2 Edit pm.ini. Add the name of the new interviewing server to the IVServerList variable (names must be separated by semicolons).

3 Open a command prompt and navigate to:

C:\Program Files\Common Files\IBM\SPSS\DataCollection\<version>\ProjectMgmt

4 Type pmsetup.

On the new interviewing server

1 Unregister the server, and then temporarily disable it: At a command prompt, type:

RegIntSvr /u /d

This enables you to activate projects on the server while ensuring that the server does not start interviews. If you start the Interview Engine at this point, the Web server tries to send interviews to the new server, but because the .mdd file does not exist on that server, respondents are redirected to another server in the cluster.

2 Copy the folders for active jobs from the File Management folder (FMRoot\Master) into the new server's Projects folder.

3 Register the interviewing server, and then enable it: At a command prompt, type:

RegIntSvr /e
