wM 6.5 onwards,
Oracle-Specific Enhancements
Support for the Oracle CLOB and BLOB Data Types
The adapter now supports the Oracle-specific CLOB and BLOB data types (java.sql.Clob and java.sql.Blob) as input parameter data types for use in adapter services.
Streaming Support of BLOB and CLOB Data with Oracle Databases
In earlier versions of the adapter, the adapter only supported the byte array and String data types when retrieving BLOB or CLOB fields. However, users sometimes encountered out of memory errors when converting large BLOB data into bytes. This version of the adapter introduces two new data types, java.io.Reader for CLOB and java.io.InputStream for BLOB, to support the streaming of byte data when working with Oracle databases.
So try AdapterService templates built-in and you shoud be able to get to what you need!!!
