"streaming of lob data is not allowed when using lob buffering"
*Cause: Attempted to stream lob data via the polling mode or a callback
when lob buffering was enabled for the input lob locator.
*Action: Lob buffering is useful when reading/writing small amounts of
lob data so streaming should not be necessary. Rewrite the
OCILobRead/OCILobWrite call so that it does not use streaming.
If streaming of data is required, lob buffering should not be
used. In this case, flush buffers associated with the input
lob locator as necessary, disable buffering on the input lob
locator and reissue the OCILobRead/OCILobWrite call.
