In using these attributes, be sure use the same case (upper, lower, mixed) that your database uses to store object identifiers. For example, Oracle stores its identifiers in uppercase. So, you set metaDataSchemaPattern to DYNAMO instead of Dynamo. See the Javadoc for java.sql.DatabaseMetaData.getColumns() for more information. See also the Logging and Data Collection chapter of the ATG Platform Programming Guide for more information about these attributes.
