To write to the LOB, you must have retrieved the LOB using the FOR UPDATE clause in the SQL SELECT statement, and you must have a local transaction started.
Calling BeginBatch more than one time within the same transaction currently throws the Oracle "ORA-22293: LOB already opened in the same transaction" error. In addition, if you obtain the LOB using another OracleDataReader, and the original caller has not called the EndBatch method, the same error is generated. Therefore, you must call the EndBatch method when you are finished using the OracleLob.
