JMS Failover Not Working
------------------------
Key: QPID-3177
URL: https://issues.apache.org/jira/browse/QPID-3177
Project: Qpid
Issue Type: Bug
Affects Versions: 0.10
Reporter: Rajith Attapattu
Assignee: Rajith Attapattu
Priority: Blocker
Fix For: 0.10
The JMS failover is not working due to a regression introduced in rev 1071631.
More specifically the reason is the following line being removed.
@@ -257,12 +256,14 @@
ConnectionClose close = exc.getClose();
if (close == null)
{
+ _conn.getProtocolHandler().setFailoverLatch(new CountDownLatch(1));
+
try
{
if (_conn.firePreFailover(false) &&
_conn.attemptReconnection())
{
_conn.failoverPrep();
- _qpidConnection.resume(); ---- > This line is removed in
this comment.
+ _conn.resubscribeSessions();
_conn.fireFailoverComplete();
return;
}
On the surface this seems like a unintended omission. However I'd like to
investigate it further and find out if this was intentional.
It if it was, then what was the reason behind it?
The obvious fix is to re-introduce this line. I have done so and preliminary
tests indicates that it will resolve the issue. I haven't seen any other issues.
However I'd like to look at more information regarding the context of the above
change before making a final decision.
