DBAdapter - Polling Exception Handling, how?

Question

Hi,
We came across the scenario where we want to be notified immediately if, for any reason, DBAdapter cannot poll information from DB. (staled connections, DB crash, etc.) Since the issue would be raised within the Adapter itself, BPEL flow wouldn't even be invoked, how would capture this exception?
Is there any recommend approach for this kind of requirement?
Any suggestion is greatly appreciated.

Hi
I checked the SQLs created by the DB adapter.
Pre Polling SQL:
UPDATE dbo.xworlds_events SET event_status = 'R${weblogic.Name-2}-91' WHERE ((object_name = 'XXX') AND (event_status = '0'))
Polling SQL:
SELECT event_id, connector_id, object_key, object_name, object_verb, event_priority, event_time, event_status, event_comment FROM dbo.xworlds_events WHERE ((object_name = 'XXX') AND (event_status = 'R${weblogic.Name-2}-91'))
After Read SQL:
UPDATE dbo.xworlds_events SET event_status = '3' WHERE ((object_name = 'XXX') AND (event_status = 'R${weblogic.Name-2}-91'))
Now the event_status column is of datatype decimal. However the SQLs above are considering this to be a varchar. Can this be the reason for the " Error converting data type nvarchar to numeric" and if yes then how can I modify these SQLs. The wizard doesnt allow me to edit it. Is there any backend file where these SQLs are stored in SOA 11G.
Thanks
