Mqseries Error 2009
Contents |
Problem(Abstract) MQ connection is terminating with error code 2009. Cause The connection may be broken for a number of different reasons. mqje016: mq queue manager closed channel immediately during connect closure reason = 2009 The 2009 return code indicates that something prevented a successful connection to mq error 2538 the Queue Manager. The most common causes for this are the following are: 1. A firewall that is websphere mq error codes terminating the connection 2. An IOException that causes the socket to be closed 3. An explicit action to cause the socket to be closed by one end 4. The queue mqje001: an mqexception occurred: completion code 2, reason 2009 manager is offline 5. The maximum number of channels allowed by the queue manager are open 6. A configuration problem in the Queue Connection Factory (QCF) Resolving the problem 1. Preventing the firewall from terminating connections: Configure the Connection Pool and Session Pool settings for the QCF that is configured in IBM WebSphere Application Server so that WebSphere can remove connections

from the pool before they are dropped by the firewall. Change the value of Min Connections to 0 and set the Unused Timeout to half the number of seconds as the firewall timeout. For example, if the firewall times out connection after 15 minutes (900 seconds), set the Unused Timeout to 450 seconds. 2. Configuring to minimize the possibility of an IOException: On a UNIX system, configure the TCP stanza of the qm.ini for the queue manager to contain this entry: KeepAlive=YES This setting causes TCP/IP to check periodically that the other end of the connection is still available. If it is not, the channel is closed. Also follow the instructions for Tuning Operating Systems in the WebSphere Application Server Information Center. These will enable the user to set the operating system configuration for TCP/IP to prevent sockets that are in use from being closed unexpectedly. For example, on Solaris, user sets the TCP_KEEPALIVE_INTERVAL setting on the WebSphere MQ machine. This should be set to be less than the firewall timeout value. If TCP_KEEPALIVE_INTERVAL is not set to be lower tha

My case is i place the messages to MQ http://www-01.ibm.com/support/docview.wss?uid=swg21472342 every 1 min once. After disconnecting the cable i get a ResonCode error but IsConnected property still show true. Is this is the right way to check if the connection is still connected ? Or there any best pratcices around that. I would like to open the connection when applicaiton is started keep it open for ever. public static MQQueueManager ConnectMQ() { if ((queueManager == null) || (!queueManager.IsConnected)||(queueManager.ReasonCode == 2009)) { queueManager = new MQQueueManager(); } return queueManager; } connection http://stackoverflow.com/questions/2951481/mq-connection-2009-error websphere-mq share|improve this question edited Sep 20 '10 at 23:03 T.Rob 23.3k84381 asked Jun 1 '10 at 16:22 user171523 1,00522344 add a comment| 1 Answer 1 active oldest votes up vote 2 down vote The behavior of the WMQ client connection is that when idle it will appear to be connected until an API call fails or the connection times out. So isConnected() will likely report true until a get, put or inquire call is attempted and fails, at which point QMgr will then report disconnected. The other thing to consider here is that 2009 is not the only code you might get. It happens to be the one you get when the connection is severed but there are connection codes for QMgr shutting down, channel shutting down, and a variety of resource and other errors. Typically for a requirement to maintain a constant connection you would want to wrap the connect and message processing loop inside a try/catch block nested inside a while statement. When you catch an exception other than an intentional exit, close the objects and QMgr, sleep at least 5 seconds, then loop around to the top of the while. The sleep is crucial because if you get caught in a tight reconnect loop and throw hundreds of connection attempts at the QMgr, you can bring even a mainframe QMgr to its knees. An alternative is to use a v7 WMQ client and QMgr. Wi

When I try to create connection to WebSpereMQ I get MQJE001: An MQException occurred: Completion Code 2, Reason 2009 MQJE016: MQ queue manager closed channel immediately during connect Closure reason = 2009 After reading different articles I tried to change CCSID by mqseries error 2009 doing MQEnvironment.properties.put(MQC.CCSID_PROPERTY, 1208); // also tried other CCSIDs like 1200,819,500 but I had no success. Than I read that a good idea is to look at MQ log files to find out if there is another process wich interrupt the connection. But I am not able to investigate that log files since they are encoded and I don't how to read them. Questions: 1) Do you know how to read MQ logs? How to make them readable? 2) Do you know what else could cause that kind of problem?

Solved MQSeries Queue Manager rejecting connection with 2009 and 2058 Posted on 2008-03-20 Java Software-Other 2 Verified Solutions 25 Comments 22,062 Views Last Modified: 2013-12-22 Hi I have a multi-threaded Java MQSeries application which runs OK most of the time. For throughput reasons, the application can be configured so that many threads can be run to read messages from a remote Queue Manager. Typically, four threads are configured to run. There are two problems.Sometimes after the application has been restarted, one or two of the threads will successfully connect to the remote Queue Manager. But the others will fail with either a 2009 or 2058 error i.e. MQJE001: An MQException occurred: Completion Code 2, Reason 2009 MQJE016: MQ queue manager closed channel immediately during connect Closure reason = 2009 and MQJE001: An MQException occurred: Completion Code 2, Reason 2058 MQJE036: Queue manager rejected connection attempt The code has retry logic, so that the connection is retried five minutes later (the code retries five times in total before giving up). Sometimes the code recovers. Sometimes, on the retry, connections that had failed with a 2009, fail with a 2058 on the retry. Sometimes, the retry fails again with a 2058. The code is quite simple. The queue manager name, host name, channel and port are all configuration parameters. MQEnvironment.hostname = hostname; MQEnvironment.channel = channel; MQEnvironment.port = port; MQQueueManager queueMan = new MQQueueManager(queueManagerName); The problem sometimes occurs after the application has started ok, and been running for a while. Due to a firewall terminating the connection, a 2009 error is incurred. On trying to reconnect to the remote Queue Manager, a 2058 is incurred. A possible thought that I have, is that the previous incarnation of the program has left some resources open in MQSeries environment somewhere. When it is restarted (new Java VM started), the MQSeries node rejects it with a 2058 which is misleading. Similarly, when the code is trying to recover from a 2009 error. A slight compl
