Error during Text Mining execution [Data Mining System Error ORA-12988: ]

Question

Hi,
When I run dmkmdemo.java sample program with the below code (starts with <code>) snippet from ODM 11g bundle, I see this below error (starts with <error> - I've created user dmuser, run the scripts):
<code>
public static void prepareData() throws JDMException
     System.out.println("---------------------------------------------------");
System.out.println("--- Prepare Data ---");
System.out.println("---------------------------------------------------");
String inputDataURI = null;
String outputDataURI = null;
OraTransformationTask xformTask = null;
// 1. Prepare build data
inputDataURI = "MINING_BUILD_TEXT";
outputDataURI = "mining_build_nested_text";
//NESTED_TABLE_BUILD_TEXT
// Create OraTextTransform
OraTextTransform txtXform = (OraTextTransformImpl)m_textXformFactory.create(
                                        inputDataURI, // name of the input data set
                                        outputDataURI, // name of the transformation result
                                        "CUST_ID", // Case id column
                                        new String[] { "COMMENTS" } ); // Text column names
// Create transformation task
System.out.println("sanku *** JDM transformation");
xformTask = m_xformTaskFactory.create(txtXform);
txtXform.setTextColumnList( new String[] { "COMMENTS" }); // for nested column list
executeTask(xformTask, "kmPrepareBuildTask_jdm");
</code>
<error>
kmPrepareBuildTask_jdm is started, please wait. kmPrepareBuildTask_jdm is failed.

Any pointers or help here please? Thanks.

Hi,
You should also consider looking at the pl/sql implementations/apis for data mining.
There is more data mining functionality within the pl/sql domain and that is defintely where the emphasis will be going forward.
To gain appreciation for the pl/sql approach you can do the following:
1) Using Data Miner Classic, it provides an option to generate pl/sql code to replicate a mining activity.
2) Using Data Miner Workflow, you can generate the sql for transformations.
We will be coming out with broader sql script generation for workflows in future releases.
3) Oracle Data Mining has sample code available on OTN.
