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 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:
[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-hand 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.
12 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 (names must be separated by semicolons).
▪Open a command prompt, and then go to C:\Program Files\Common Files\IBM\SPSS\DataCollection\<version>\ProjectMgmt. Type pmsetup.
13 On the new interviewing server, open a command prompt, type RegIntSvr /u /d to unregister and disable the server temporarily.
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) into the new server's Projects folder.
15 At a command prompt, type RegIntSvr /e to register and enable the interviewing server.
