35.1introduction
The Oracle Business Intelligence (BI) Cloud Connector makes it easy to extract business intelligence data from a Fusion Applications Cloud data source to an Oracle storage service or UCM server.
Oracle Data Integrator (ODI) integrates seamlessly with Oracle BI Cloud Connector. Oracle Data Integrator features are designed to work best with Oracle BI Cloud Connector, including reverse engineering and mappings.
35.1.1concepts
Oracle BI Cloud Connector technology concepts map to Oracle Data Integrator concepts as follows: An Oracle BI Cloud Connector instance corresponds to a data server in Oracle Data Integrator. In this instance, a schema is mapped to a physical Oracle Data Integrator schema.
The Oracle BI Cloud Connector data server contains a reference to the object store used by Oracle BI Cloud Connector to serve the extracted files. Used object storage can beOracle Object StorageoOracle Cloud Storage Service.
35.1.2knowledge modules
Oracle Data Integrator provides the following Knowledge Modules (KMs) for processing Oracle BI Cloud Connector data.

Outdoor table from LKM BICC to ADW
-
Copy of LKM BICC for ADW
-
Direct copy from LKM BICC to ADW
35.5.1.1Outdoor table from LKM BICC to ADW
This KM helps to load data from Oracle BI Cloud Connector into Oracle ADW using external table method. You can use this LKM in combination with Oracle or generic SQL IKM.
kilometer options
This KM has the following options:
-
CREDENTIAL_NAME— The name of the credential to store. The default is ODI. -
CREATE_CREDENTIAL— Create new credentials. If the value is set to false, ODI will reuse existing credentials. -
GENERATE_FIELD_LIST— If this KM option is set to False, the field_list clause is ignored and the default ORACLE_LOADER gatekeeper settings are applied. -
SUBMIT_BICC_JOB— Oracle BI Cloud Connector has its own scheduler that you can configure to extract data and store it as zipped CSV files in object storage. You can set this in ODISUBMIT_BICC_JOBoption to False and just get the data pulled from object storage (all data or fromLAST_LOAD_DATE). If you prefer not to use the Oracle BI Cloud Connector scheduler or want to ensure that nothing is left to extract from the last scheduled job, you can let ODI run the extract job, which creates a job to extract the data. Wait for it to complete and then retrieve the data from the object store. -
LAST_LOAD_DATE— This option allows you to specify the date of the previous upload of the extracted data.
Format
-
DELIMITED_FILE_FORMAT— Specifies the delimited file format and can be CSV (default) or a generic delimited format known to the ORACLE_LOADER access driver. You can use this KM option only if the source data store's File Format property is set to Delimited. -

DATE FORMAT— Helps to set a specific date format. -
TIMESTAMP_FORMAT— Helps to set a specific time format. -
REJECT_LIMIT— The query helps to display an error message after the specified number of rows have been rejected. The default value is zero. -

TRIM_SPACES— Helps trim gaps in front of and behind fields. When set to True, specified spaces are trimmed. -
IGNORE_BLANK_LINES— If set to True, blank lines are ignored without throwing an error. -
IGNORE MISSING COLUMNS— If field_list contains more columns than the source files, the extra columns are stored as null. -
TRUNCATE_COLUMNS— If the data in a file is too long for a field, this option truncates the field value instead of rejecting the line.
