Load balancing settings
Registry settings for load balancing of UNICOM Intelligence projects are stored under the following key:
HKEY_LOCAL_MACHINE\Software\SPSS\mrInterview\3\LoadBalancing
Settings
CachedProjectWeight
The percent weighting by which to reduce the percent loaded if the project is cached. Set this property to zero if you want to ignore project affinity when load balancing UNICOM Intelligence projects.
Default value: 50
CompletesPerSecLimit
The maximum number of engine completes per second, as specified in the registry.
Default value: 100
ConnectionLimit
The maximum number of interviews that an interviewer session engine can run.
This setting does not directly limit the number of interviews that can be run. Instead, it is a value that the load balancing algorithm uses to calculate PercentLoaded. If the ConnectionLimit is reached, the default load balancing script sets PercentLoaded to 100, so this indirectly limits the number of interviews that can be run.
Default value: 1000
ErrorsPerSecLimit
The maximum number of mrEngine errors per second, as specified in the registry.
Default value: 30
LoadBalanceOnRestart
Indicates whether load balancing should be rerun when an interview is restarted after timing out. A value of 0 indicates that load balancing should not be rerun.
Default value: 0
LoadBalancingScript
The full pathname of the load balancing script file.
Default value:
<UNICOM Intelligence Interviewer folder>\Server\defaultload.mrs
RequestsPerSecLimit
The maximum number of mrEngine requests per second, as specified in the registry.
Default value: 250
RestartsPerSecLimit
The maximum number of mrEngine restarts per second, as specified in the registry.
Default value: 50
StartsPerSecLimit
The maximum number of interviews that can be started per second on an interviewer session engine.
Default value: 100
TimeoutsPerSecLimit
The maximum number of mrEngine timeouts per second, as specified in the registry.
Default value: 100
