You can troubleshoot and resolve commonly encountered problems or errors with Decision Strategy Manager components such as Adaptive Decision Management, decisioning rules, Predictive Analytics Director, and Revision Management. Each problem or error is accompanied by a description, a cause, and a suggested solution.

Adaptive Decision Management

The following problems or errors can occur while working with Adaptive Model rules:

• Activity pzUploadCSVFile failed - Cannot upload responses
• Adaptive Decision Manager does not capture responses for adaptive models
• Adaptive models do not contain active predictors, or only one active predictor
• Adaptive models have low performance
• Behavior report is empty
• No models are displayed in the Adaptive Models Management landing page
• No models are displayed in the Adaptive Models Reporting landing page
• Problems with uploading responses
• The Adaptive Decision Manager node fails to join the Cassandra cluster
• Timeout exceptions during snapshot generations
• Troubleshooting an adaptive model with exceedingly high performance
• Troubleshooting an adaptive model with no active predictors
• Troubleshooting an adaptive model with only one active predictor
• Values of the predictors are not set
• Values of the parameterized predictors are not set

Data Flow rule

The following problems or errors can occur while working with data flows:

• Data flow run does not progress past Pending-Start or Pending-Activation stage
• Data flow returns errors while writing records to a database data set
• Exceeded threshold for error count in real-time data flow run
• No data flow service nodes are available
• The data flow cannot parse JSON records

Decision Data rule

The following problems or errors can occur while working with Decision Data rules:

• Interaction History tables are not upgraded after migration
• Interaction History component processes data longer than expected
• The pyApplication and pyApplicationVersion properties are not captured in the interaction history
• Values of the pxOutcomeTime property are not unique in the Oracle database

Predictive Analytics Director

The following problems or errors can occur while working with the Predictive Analytics Director portal:

• Default templates and projects are missing
• Loading data into Predictive Analytics Director takes a long time
• Predictive Analytics Director runs out of the allocated memory
• Problem with setting the sample size

  • The PMML model does not pass schema validation
  • The PMML model contains undefined functions
• Problems with the execution of a PMML model
  • Discrepancies in PMML model output on different systems
  • Errors when running the PMML model

Proposition Filter rule

You can enable debugging of proposition filters to find the root cause of errors or unexpected strategy results. For more information, see Troubleshooting Proposition Filter rules.

Revision management
