Well by the How!!?? I get the feeling you think this is impossible. Hope your MQ isn't setup in the same way... There is are a couple of interesting MQ presentations on security (more lack of...) and holes on ebizQ.net -----Original Message----- From: Ronald Weinger [ mailto:[EMAIL PROTECTED] Sent: Tuesday, August 05, 2003 7:24 PM To: [EMAIL PROTECTED] Subject: Re: cause of channels out of sequence? a hacker is inserting messages into your channel How!!??

A more extreme case related to Steve's cause: If you are upgrading MQ on Server1 and choose to uninstall/reinstall MQ on Server1, and there are actively running channels to/from Server1, you will have sequence # errors on the remote servers once you reinstall MQ and rebuild the QM. -----Original Message----- From: Steve D.

Deleting and then recreating the channel on one queue manager and not the other will also cause this problem. -----Original Message----- From: MQSeries List [ mailto:[EMAIL PROTECTED] Behalf Of Benjamin Zhou Sent: Tuesday, August 05, 2003 8:41 AM To: [EMAIL PROTECTED] Subject: cause of channels out of sequence? Win2k, MQ5.2: Occasionally, a pair of channels between two qmgrs on different machines become out of sync, while the sender MCA tries to send a message with sequence number 1, but the receiving side is expecting a different one, say 300. While this is easy to fix, I want to understand what cause the problem. I enabled tcp/ip keep alive, set heartbeat interval to 60 sec, and discint to 600 sec. Can anyone shed some light on what's behind this out-of-sequence? thanks a lot. Benjamin Zhou State Street Corp.
