Brainbread 2 connection failed code#
If the Queue Manager, Host, Port, and Channel properties are not set correctly (for example, the MQ Channel name is case-sensitive), then a Reason Code 2009 would occur when an application uses the QCF to try to connect to the queue manager. This problem could also occur because of a QCF configuration problem. Also, WebSphere Application Server and MQ do not agree on the number of JMS connections. For additional information, refer to these technotes, MQ Manager Stops Responding To JMS Requests. This could be due to the number of channels for the JMS provider not being large enough, or there could be some errors occurring that are causing channels to not close, so that they cannot be reused. The maximum number of channels has been reached Go to the MQ support page to see if there are any known APARs that apply to your environment that have this Reason Code as a symptom.

There have been some MQ defects that could result in unexpected 2009 errors. A connection broken error could be caused by the firewall not letting the keepalive packets through.Īn action such as stopping the queue manager or restarting the queue manager would also cause Reason Code 2009. NOTE: You must be sure that the firewall is configured to allow keepalive packets to pass through.

If you do not set the TCP_KEEPALIVE_INTERVAL to be lower than the firewall timeout, then the keepalive packets will not be frequent enough to keep the connection open between WebSphere Application Server and MQ.

This should be set to be less than the firewall timeout value. For example, on Solaris, you will set the TCP_KEEPALIVE_INTERVAL setting on the WebSphere MQ machine. These will have you set the operating system configuration for TCP/IP to try to prevent sockets that are in use from being closed unexpectedly. If it is not, the channel is closed.Īlso follow the instructions in Tuning operating systems in the WebSphere Application Server Info Center. This setting causes TCP/IP to check periodically that the other end of the connection is still available. On a UNIX® system, configure the TCP stanza of the qm.ini for your queue manager to contain this entry: For example, if the firewall times out connections after 15 minutes (900 seconds), set the Unused Timeout to 450 seconds.Ĭonfiguring to minimize the possibility of an IOException Change the value of Min Connections to 0 and set the Unused Timeout to half the number of seconds as the firewall timeout. Preventing the firewall from terminating connectionsĬonfigure the Connection Pool and Session Pool settings for the QCF that is configured in WebSphere Application Server so that WebSphere can remove connections from the pool before they are dropped by the firewall.
