The following problems occur when you run Data Miner 3.1, 3.2, or 3.3 when connected to Oracle Database 12c Release 1 (12.1):
Apply Node
Data types generated by Model Apply have changed in Database 12c. With the introduction of the Native Binary Data Type Project, several data types such as prediction_set, are now binary_float and binary_double. All the complex apply output types (prediction_set, feature_set and cluster_set) have these data type changes.
Downstream nodes from a Apply node may fail due to data type mismatches. The complex type have different data types as well as the probability values (binary_double in Oracle Database 12c Release 1 (12.1)) and the prediction values (which can be binary_double as well as binary_float in Oracle Database 12c Release 1 (12.1)).
Naive Bayes Models
View Naive Bayes model and view Naive Bayes Test result (ROC, Lift, Profit) mat fail.
View Naive Bayes Test results in Oracle Database 12c Release 1 (12.1) may result in ORA-00903 invalid table name).
GLM Regression build may fail because of inconsistent settings in Oracle Database 12c Release 1 (12.1).
Decision Tree Model PredictionSet operator may fail when a cost matrix is used. This failure causes Classification Build node to fail when it generates test result.s.
