The reading and writing of LOBs is done by the class AbtOracleLobBuffer. There is a class side method, ‘maxBufferLength’ which is set to 1000. In other words, when reading or writing to/from a file, it is done in chunks of 1000 bytes. This number can be changed to suit your needs.

LOBs are written in pieces. When a LOB is written to the database, the chunk being written must be labelled as the first, last, or next piece. The methods are not long but if you want to write your own methods for reading or writing LOBs, the existing methods will give you a good idea of what is required.

Finally, whether the LOB is character or binary, the methods use byte arrays.
