| ERROR | unable to write to the ORDImageSignature object |
| CAUSE | The signature object was not valid and therefore the write operation failed. This problem is commonly caused by an attempt to invoke the generateSignature method on an uninitialized ORDImageSignature object. |
| ACTION | Ensure that the ORDImageSignature object has been initialized and inserted into a table. Also ensure that the row containing the signature object is locked. (The two previous actions do not apply to signature objects created using temporary BLOBs). Ensure that there is sufficient tablespace to contain the signature. |
