Failure Description: ORA-44002: invalid object name

Question

Hi,
I'm trying to use O-cluster to find clusters in my data programmatically. 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.

Arthur suggestion works but you shouldnt even be doing this on a SQL Task.
Use a data flow task. You'll have better control over the data that is being transfered and get better performance because no staging table will be used.
Just because there are clouds in the sky it doesn't mean it isn't blue. But someone will come and argue that in addition to clouds, birds, airplanes, pollution, sunsets, daltonism and nuclear bombs, all adding different colours to the sky, this
is an undocumented behavior and should not be relied upon.
