Logging for smart large objects

Use logging for smart large objects if users are updating the data frequently or if the ability to recover any updated data is critical. The database server writes a record of the operation (insert, update, delete, read, or write) to the logical-log buffer. The modified portion of the CLOB or BLOB data is included in the log record.

To increase performance, turn off logging for smart large objects. Also turn off logging if users are primarily analyzing the data and updating it infrequently, or if the data is not critical to recover.
