Improve Network Server Exception Handling
-----------------------------------------
Key: DERBY-1011
URL: http://issues.apache.org/jira/browse/DERBY-1011
Project: Derby
Type: Improvement
Components: Network Server
Versions: 10.2.0.0
Reporter: Kathey Marsden
I think that there needs to be a comprehensive look at the Network Server
exception handling, which is an ongoing area of concern. I am not sure how
much can be done from a DRDA perspective but it would definitely be worth a
look.
- Exceptions are localized with a stored procedure call which is
problematic when the procedure can't be called because of a serious error and
traditionally has caused other issues as well. It seems like somehow we could
negotiate the client locale up front and send back the localized message
- Multiple exceptions are flattenned into one and there is limitted space
to send parameter info to the client. (70 characters according to DRDA).
- Many warnings do not get returned to the client.
- I think SQLExceptions thrown by the Network Server are not getting logged
to derby.log
