ORA-22993 specified input amount is greater than actual source amount

Cause:

  1. For LOB write, the amount of data received is different from the amount that was indicated would be sent.

Solution: (1) will happen when using OCI’s piecewise mechanism with polling or with a callback function. Modify the code either to send the amount specified or to pass 0 as the input amount so that any amount of data can be sent. (2) will happen if the specified input amount is too large for the source LOB/FILE given the starting source offset. Either decrease the starting source offset, or decrease the amount to copy/load.
