Manually update files on the primary server
To add a new Interviewing Server to an existing cluster with live respondents, without disrupting the service for respondents currently taking surveys, complete the following 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 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 directory, and then run the installation program from there.
The services and utilities to be installed should be already selected (based on the information that is in the DataCollectionSitePrep.ini file). If they are not selected, cancel the installation; copy the DataCollectionSitePrep.ini file next to the "UNICOM Intelligence Server <version_number> (x64).exe" in the UNICOMIntelligence\win64\Server folder; and then run the installation program again.
6 Go to the following folder:
[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., and then click DefaultCluster.
9 In the lower right frame, add the name of the new interviewing server to the IVServerList variable (separate names by using semicolons), and then click Apply.
10 Close DPM Explorer.
11 On the original interviewing server, do the following:
▪Go to C:\Program Files\Common Files\IBM\SPSS\DataCollection\<version>\ProjectMgmt, and then edit the pm.ini file. Add the name of the new interviewing server to the IVServerList variable (separate names by using semicolons).
▪Open a command prompt, and then go to C:\Program Files\Common Files\IBM\SPSS\DataCollection\<version>\ProjectMgmt. Type pmsetup.
12 Log on to the new interviewing server as a user who has trusted user access to DPM. This is typically the installing or running user.
13 Open a command prompt, and then type the following command to unregister and disable the server temporarily:
RegIntSvr /u /d
This allows 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.
14 Copy the folders for active jobs from the File Management folder (FMRoot\Master) to the new server's Projects folder.
15 At a command prompt, type the following command to register and enable the interviewing server:
RegIntSvr /e
