Mq Connection 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. The 2009 return code indicates that something mqje016: mq queue manager closed channel immediately during connect closure reason = 2009 prevented a successful connection to the Queue Manager. The most common causes for mq error 2538 this are the following are: 1. A firewall that is terminating the connection 2. An IOException that causes the socket to websphere mq error codes be closed 3. An explicit action to cause the socket to be closed by one end 4. The queue 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 mqrc 2009 in mq 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 than the firewall timeout, then the keepalive packets will not be frequent enough to keep the connection open between WebSphere Application Server and MQ. NOTE: Check that the firewall is configured to allow keepalive packets to pass through. A connection broken error cou

Closed as program error. Error description MQ V8.0 Managed .NET client application fails to connect to a MQ v7.5 queue manager and reports MQRC_CONNECTION_BROKEN (mqrc 2009), if it sets user ID and password. Local fix http://www-01.ibm.com/support/docview.wss?uid=swg21472342 As a work around, MQC.USER_ID_PROPERTY and MQC.PASSWORD_PROPERTY properties can be removed to turn off password encryption. This will make MQ client to send the Windows logged in user id to queue manager for authorization. [This needs creating a user with the same name as the logged in user and then granting it authority to connect, put and get on the QM]. Problem summary **************************************************************** USERS AFFECTED: Users using MQ http://www-01.ibm.com/support/docview.wss?uid=swg1IT08484 version 8 Managed .NET client application that sets user ID/password and connects to a MQ v7.5 queue manager. Platforms affected: Windows **************************************************************** PROBLEM DESCRIPTION: An MQ version 8.0 Managed .NET client application failed to connect to a MQ v7.5 queue manager if the application set user ID and password parameters for the connection. In MQ v8, the client sends a secured password to a version 8 queue manager during connection. However, a version 7.5 queue manager does not understand the secured password structure. The version 8 client did not correctly account for this when communicating with a version 7.5 or earlier queue manager and sent an incorrect password structure. In response to this, the queue manager safely closed the connection and application reports an error with reason code 2009. Problem conclusion The problem is resolved by correctly checking the queue manager level and only sending the secured password structure if the queue manager is at version 8. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.0 8.0.0.3 The latest available maintenance can be obtained from 'WebSphere MQ Recommended Fixes' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006037 If the maintenance level is not yet available information on its planned availability can be found in 'WebSphere MQ Planned M

Instead I mq connection error am getting 2059. All I am doing is disconnecting SVRCONN channel while making the connection call. How can I get 2009 in my sample code. I have added a sleep time prior making connection again and using transacted sessions. What else can be done to handle reason code 2009 properly that eventually Queue manager won't get thrashed by frequent unsuccessful connection attempts. Please find the code. private static void connectToQmgr(MQQueueConnectionFactory cf) { // TODO Auto-generated method stub MQQueueConnection connection = null; MQQueueSession session = null; MQQueue queue = null; MQQueueSender sender = null; //While Statement to make sure multiple connection tries are made until connection establishes while (connection == null){ try { connection = (MQQueueConnection) cf.createConnection(); session = (MQQueueSession) connection.createQueueSession(true, Session.CLIENT_ACKNOWLEDGE); queue = (MQQueue) session.createQueue("queue:///LQ"); sender = (MQQueueSender) session.createSender(queue); //MQQueueReceiver receiver = (MQQueueReceiver) session.createReceiver(queue); long uniqueNumber = System.currentTimeMillis() % 1000; TextMessage message = session.createTextMessage("MQJMSTest "+ uniqueNumber); // Start the connection connection.start(); sender.send(message); session.commit(); System.out.println("Sent message:\\n" + message); // JMSMessage receivedMessage = (JMSMessage) r
: Sometimes MQ connection does not close even after calling close method. It gives us MQ Error code-2009. I found out solution for this problem after a long struggle and hit & try, so i thought to share it with everyone. Solution : What most people do the mistake is that they close queue connection before queue manager connection. When you close queue connection first then it made queue manager connection unavailable and open inspite of firing disconnect method on queue manager connection after queue close. IBM MQ close these open connections self but when you create connection very frequently before MQ close them and eventually it gives you 2009 error. So always close queue manager before queue connection. Other related posts are : Top 10 spring interview questions and their answers. Spring basic concepts.
