IBM SPSS Data Collection Interviewer Server installation information
Modifying TCP/IP registry settings on Interview and Web servers in a cluster
Note
: These instructions are only intended for use with Interview and Web servers. The settings
outlined in this topic should not be employed in any other environment.
In cluster installations, if the Interview or Web servers run out of available ports, interviews will
fail. An indication that a server is failing because of insuf
fi
cient available socket ports is the
following message in the IVW logs:
Error calling WS method 'Method'. URL 'URL', Error codes: Client 5, HTTP -1, SOAP 0, TCP 10048
You can prevent this from happening by changing either of
the following settings for TCP/IP in the Windows registry
(HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters):
Increase the port range that is used for anonymous ports to approximately 20000 ports (for
example) by modifying the
MaxUserPort
registry key.
Change the connection time-out set in
TcpTimedWaitDelay
from the default 240 seconds to
anything from 30 to 300 seconds.

Things you must do if they are not done automatically
Register the Interview Service machines with the Web Service machines
Start mrUserAdminServer and mrDPMServer3
if they are not already running
Check that access permissions are set correctly for FMRoot and all its subfolders
Registering Interview Service machines with Web Service machines
When installing the Interview Service, the installer registers the Interview Service machine with
all machines currently running the Web Service. If you install the Interview Service before you
have installed IBM® SPSS® Data Collection Interviewer Server on all your Web servers, the
registration of that Interview server with the Web servers cannot take place. When this happens
you will need to register the Interview Service machine manually. There are two ways of doing
this.
Either:
E
Reboot each Interview Service machine that you want to register.
Or:
E
On each Interview Service machine to be registered, navigate to
[INSTALL_FOLDER]\IBM\SPSS\DataCollection\6\Interviewer Server\Server and run
RegIntSvr.exe.
