Determining whether your application has the queue open - Middleware News



If you have a problem with a queue, check whether your application has the queue open
About this task
Perform the following steps to determine whether your application has the queue open:
Procedure

Ensure that the application that is running against the queue is the application that you expect. Issue the following command for the queue in question:

DISPLAY QSTATUS(Q1) TYPE(HANDLE) ALL

In the output, look at the APPLTAG field, and check that the name of your application is shown. If the name of your application is not shown, or if there is no output at all, start your application.
If the queue is a transmission queue, look in the output at the CHANNEL field. If the channel name is not shown in the CHANNEL field, determine whether the channel is running.
Ensure that the application that is running against the queue has the queue open for input. Issue the following command:

DISPLAY QSTATUS(Q1) TYPE(QUEUE) ALL

In the output, look at the IPPROCS field to see if any application has the queue open for input. If the value is 0 and this is a user application queue, make sure that the application opens the queue for input to get the messages off the queue.

Troubleshooting Java/JMS SSL Configurations - Middleware News

 This document is intended to help diagnose WebSphere MQ V7 Java™ or JMS SSL setup errors. It lists most of the common configuration errors that can cause an SSL connection from a Java/JMS client to a queue manager to fail, and gives the course of action to resolve the problem. In each case the error can be diagnosed by a combination of the error seen in the client log - either a console output, trace file or SystemOut.log file - and the queue manager's error logs. The document is quite long, so the easiest way to find the potential error is to search for one of the errors seen in this list, then filter this list using the error from the opposite end of the channel. All cases here assume that 2-way authentication is being attempted (SSLCAUTH set to REQUIRED on the queue manager's SVRCONN channel). This is the default, and the errors are very similar for 1-way authentication (SSLCAUTH set to OPTIONAL). Symptom Instructions on collecting documentation...

Using telnet to test connectivity between IBM Websphere MQ Client and MQ server - Middleware News

You are having trouble connecting a WebSphere MQ client to a MQ server, receiving errors that you can not connect to the MQ queue manager. One of the first things to determine is if the two machines can communicate, and using the telnet tool is one way to accomplish it. Symptom Receiving errors which state that a queue manager is not found or not available. Connection errors. For example: AMQ9213, AMQ9524, AMQ9202 or AMQ9508 or MQRC =2059 0x0000080b MQRC_Q_MGR_NOT_AVAILABLE. Please note, this is by no means an exclusive list of errors related to this type a problem but just a sample of some of the more common error messages and codes that might occur. Cause One possible cause is that the two machines can not communicate. May be the IP address or hostname was not properly specified by the MQ client. The port number might be incorrect. A queue manager is not running at the desired host. The queue manager could be running, but the corresponding listener is not runnin...
