ORA-40101: Data Mining System Error ORA-40101: Data Mining System Error ORA

Question

Hi,
I'm using Oracle 10.2.0.1.0 with Data Mining. I was able to build and apply models on my data using the OD Miner tool. However, I'm unable to do so programatically. Even the demo programs give the same error
ocBuildTask_jdm is started, please wait. ocBuildTask_jdm is failed.
Failure Description: ORA-40101: Data Mining System Error ORA-40101: Data Mining System Error ORA-40104: invalid training data for model build
ORA-06512: at "DMSYS.DBMS_DATA_MINING", line 305

Thanks, George. When I try to bin the data (using a modified version of the dmocdemo.java), I get the following error
Failure Description: ORA-44002: invalid object name
Details -
I'm trying to cluster data in my table (see desc below) based on values of evt_hostname, evt_key and evt_username;
SQL> desc sc.sc_event_store;
Name Null? Type
EVT_SEQNO NOT NULL VARCHAR2(64)
EVT_HOSTNAME NOT NULL VARCHAR2(64)
EVT_TIMESTAMP NOT NULL TIMESTAMP(6)
EVT_ID NOT NULL NUMBER(8,2)
EVT_CAT_ID NUMBER(8,2)
EVT_SERVERSTATE NUMBER(8,2)
EVT_USERNAME VARCHAR2(64)
EVT_KEY VARCHAR2(2048)
EVT_VALUE VARCHAR2(64)
EVT_RECUR_TAG NUMBER(15,2)
EVT_CLUSTER_ID VARCHAR2(64)
I've modified prepareData() in dmocdemo.java like this
isOutputAsView = false;
inputDataURI = "SC.SC_EVENT_STORE";
outputDataURI = "OC_BINNED_DATA_BUILD_JDM";
// Create boundaries for all numeric attributes
OraBinningTransformImpl buildDataXform =
(OraBinningTransformImpl)m_binningXformFactory.create(
inputDataURI, outputDataURI, isOutputAsView );
//buildDataXform.setLiteralFlag(true);
String[] excludeColumnList = {"EVT_SEQNO","EVT_TIMESTAMP","EVT_ID","EVT_CAT_ID","EVT_SERVERSTATE","EVT_VALUE","EVT_RECUR_TAG","EVT_CLUSTER_ID"};
buildDataXform.setExcludeColumnList(excludeColumnList);
buildDataXform.setNumberOfBinsForCategorical(125);
//buildDataXform.setNumericalBinningType(OraNumericalBinningType.auto_equi_width);
buildDataXform.setCategoricalBinningType(OraCategoricalBinningType.systemDefault);
xformTask = m_xformTaskFactory.create(buildDataXform);
executeTask(xformTask, "ocPrepareBuildTask_jdm");
The executeTask() function tries executing the task, but returns with
Failure Description: ORA-44002: invalid object name
Any insight/help will be greatly appreciated.
