Switching trace logging on and off
If an activity fails to work as expected and you cannot see what the problem is from the standard log files, you can request logging at "trace level" to generate very detailed reports of what the activity has been doing. To do this, set the Filter key to 0 in the following locations in the registry:
HKEY_LOCAL_MACHINE\Software\SPSS\DimensionNet\Log
HKEY_LOCAL_MACHINE\Software\SPSS\mrInterview\3\Log
HKEY_LOCAL_MACHINE\Software\SPSS\MRPropertyManagement\2.0\Log
HKEY_LOCAL_MACHINE\Software\SPSS\MRPropertyManagement\2.0\Security\Auditing
Note If you are running 32-bit software on a 64-bit machine, the SPSS key might be located in HKEY_LOCAL_MACHINE\Software\Wow6432Node instead of HKEY_LOCAL_MACHINE\Software.
You must make the change in all locations as you cannot be sure which application will start the logging component. For consistency, make the change on all computers running the Interviewing and Accessories Services.
Trace logging writes large amounts of information to the log files, so be sure to turn it off once you have resolved the problem. To turn trace logging off, reset the Filter key to (decimal) 16 which is the default setting for this key. Once again, be sure to make the change in all locations and on all computers.
You must wait one minute for the settings to take effect.
Dialer trace logging
You can enable or disable trace logging for your dialer by updating the following HKEY_LOCAL_MACHINE\SOFTWARE\SPSS\mrInterview\3\Log\ registry values on your server:
Directory: This string value indicates the log file location. Specify an appropriate location for your trace log files.
DialerTrace: If this DWORD Value does not already exist, you must create it. This value controls when trace logging is enabled or disabled. Providing a value of 1 enables trace logging; providing a value of 0 disables trace logging.
The trace log file name is determined by the type of dialer that is employed. For example, the trace log is named QSampTrace.txt when the is used and ProTSTrace.txt when a Pro TS dialer is used.
After updating the DialerTrace logging registry setting, you must reset IIS.
