I posted this in user but got no response. Maybe somebody has some ideas here.
Messages left in a topic with a durable subscriber when jboss is shutdown will
never be sent/received. They appear in the message count in the jmx console but
if mq must go back and load it from storage the message will never be sent to a
receiver. Post restart, when a subscriber connects with the appropriate
clientID and subscription name if an internal ref to the message does not exist
PersistenceMgr.loadFromStorage reads the jms_message_log table using keys
messageid and destination. The destination value for topic messages with
durable subscribers is '*' in jms_message_log.
| try
| {
| c = this.getConnection();
| stmt = c.prepareStatement(SELECT_MESSAGE);
| stmt.setLong(1, messageRef.messageId);
| System.out.println("x" + messageReg.getPersistnen
|
| stmt.setString(2, messageRef.getPersistentKey());
|
| rs = stmt.executeQuery();
| if (rs.next())
| return extractMessage(rs, 2);
|
| return null;
|
The messageRef.getPersistentKey returns the destination from jms_reference_log
(clientid, name, and selector), the row is never found and the function returns
null.
This also blocks any new messages that are added after the startup. When a
subscriber connects and attempts to get messages either synchronously or
asynchronously the system throws a null pointer exception due to the code above
and never gets past the first message.
Messages written to topics with durable subscribers that are read before a
shutdown work as the system has an internal ref of some sort and does not
attempt to load from storage.
Is there a patch that makes this work anywhere that anyone knows of or should I
just switch to JDBC2 which does not include the jms_reference_log table and
hopefully works on restart
