Lily Wei commented on DERBY-4986:
---------------------------------
Thanks Kim for the feedback:
The property is a flag that decide whether thread dump information and extend
diagnostic information get created. This is the system wide flag. The default
value is 40000(ExceptionSeverity.SESSION_SEVERITY) User can set it to
WARNING_SEVERITY = 10000,
STATEMENT_SEVERITY = 20000,
TRANSACTION_SEVERITY = 30000,
SESSION_SEVERITY = 40000,
DATABASE_SEVERITY = 45000,
SYSTEM_SEVERITY = 50000
If they use the default value, the thread dump information and diagnostic
information will only get print to derby.log when error severity is equal or
greater than SESSION_SEVERITY. If they set it to number that is greater than
50000, no information will be print to derby.log i.e.
derby.stream.error.extendedDiagSeverityLevel=30000
You are right about this is a system wide flag. I am in the middle of
preparing the releaseNote.html. I am not sure the information is clear enough.
Kathey is helping me reviewing it. I am sorry for not provide enough
information for documentation.
