Back 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 will try to send
interviews to the new server, but because the
.mdd
fi
le does not exist on that server, respondents
will be redirected to another server in the cluster.
E
Copy the folders for active jobs from the File Management folder (FMRoot\Master) into the
new server’s Projects folder.

At a command prompt, type
RegIntSvr /e
to register and enable the interviewing server.
Adding session engines to an IBM SPSS Data Collection Interviewer Server
Each Interview Session Engine runs within its own w3wp.exe worker process. These worker
processes become unstable when their memory usage reaches about 1.5Gb. You can avoid this
problem by adding additional Interview Session Engines to your IBM® SPSS® Data Collection
Interviewer Servers, as long as the machines that are hosting the Engines have suf
fi
cient memory.
This automatically adds additional worker processes which effectively doubles the amount of
memory that each server can use for serving interviews.
E
In Windows Explorer, browse to [INSTALL_FOLDER]\IBM\SPSS\DataCollection\6\Interviewer
