ORA-22280: no more buffers available for operation

Reason for the Error

There are two causes: (1) All buffers in the buffer pool have been used up by previous operations (2) Attempt to flush a LOB without any previous buffered update operations.

Solution

For (1), flush the LOB(s) through the locator that is being used to update the LOB. For (2), write to the LOB through a locator enabled for buffering before attempting to flush buffers.
