Steven Hawkins commented on TEIID-3400:
---------------------------------------
Added a hook so that a cancelled oracle statement will have connection isvalid called on
the statement close. This seems to clear whatever the issue is that causes later
statements to fail. Will do more testing to ensure things look good.
Oracle connection not consistently usable after cancel

Key: TEIID-3400
URL:
https://issues.jboss.org/browse/TEIID-3400
Project: Teiid
Issue Type: Quality Risk
Components: Misc. Connectors
Affects Versions: 8.10
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Fix For: 8.11
With TEIID-3275 we made use of cancel calls more to ensure that cleanup was happening as
quickly as possible. However Oracle JDBC has a bug (independently reproducible outside
Teiid) where if the cancelled statement does not reach the point of thrown an exception
related to the cancel, then the next statement from that connection will throw the
exception.
