IBM Websphere MQ - Probe id XC338001 FDCs reporting SIGTERM - Middleware News


Your queue manager ended as a result of the server being rebooted. You restarted your queue manager and noticed many FDCs with probe id XC338001, component xehAsySignalHandler:

Symptom

Example of FDC:
Probe Id :- XC338001
Component :- xehAsySignalHandler
Major Errorcode :- xecE_W_UNEXPECTED_ASYNC_SIGNAL
Comment1 :- SIGTERM
+-------------------------------------------------------
MQM Function Stack
xehAsySignalMonitor
xehHandleAsySignal
xcsFFST

Cause

The server was rebooted without first shutting down the queue manager.

Resolving the problem

This is working as designed.
You need to shut down your Queue Managers before rebooting the system to avoid these FDC reports.
Additional information
Usually there were many reports of this type of FDC from various WebSphere MQ processes and all these reports were created within a few seconds. The server was rebooted without shutting down the queue manager. Under these conditions it is expected, and desirable behavior to produce the FDCs.

Such FDCs are to record the fact that an MQ process (that is, the process that writes the FDC file) has received an asynchronous signal. These FDCs do not indicate a problem originating within MQ and they are "informational"; that is, they are not an indication of any MQ failure at all.

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...

IBM Websphere MQ interview Questions Part 5

MQ Series: - It is an IBM web sphere product which is evolved in 1990’s. MQ series does transportation from one point to other.

It is platform Independent. For every OS we have different MQ series software’s. But the functionality of MQ series Default path for installing MQ series is:- C: programfiles\BM\clipse\SDK30 C: programfiles\IBM\WebsphereMQ After installation it will create a group and user. Some middleware technologies are Tibco, SAP XI. MQ series deals with two things, they are OBJECTS, SERVICES. In OBJECTS we have • QUEUES • CHANNELS • PROCESS • AUTHENTICATION • QUERY MANAGER. In SERVICES we have LISTENERS. Objects: – objects are used to handle the transactions with the help of services. QUEUE MANAGER maintains all the objects and services. QUEUE: – it is a database structure ...
