How to Stop all MQ Processes?

Posted by Vivek on October 26, 2014

1. Login as mq admin user

2. Use the endmqm command to stop all running queue managers.

endmqm {BROKERNAME}

3. Stop any listeners associated with the queue managers, using the
command:

endmqlsr -m {BROKERNAME}

4. To check that you have stopped all of them, enter the following

ps -ef | grep mq

5. Check that there are no processes listed that are running command lines beginning amq or runmq. Ignore any that start with amqi.

Java based integration framework

Posted by Vivek on July 8, 2014

We all know the capabilities of an ESB to enable seamless integration among hetrogeneous applications. But is it always a feasible to choose an ESB where integration is not a major challenge and where applications use common protocols? The answer is NO. Most of the companies are looking for open source options which allows them build an integration architecture using simple configuration. Two of the most commonly used frameworks are:

1. Spring Integration

  • Based on popular Spring application framework
  • Dependency Injection / Inversion of Control
  • Configured within Spring Container
  • XML / Annotation based DSL
  • Supports Spring expression language

 

2. Apache Camel

  • Apache Software Foundation project
  • Custom Container – Camel Context
  • Can be instantiated directly from Java method
  • Integration with Spring, Guice, OSGI

Purge messages from queue using Groovy/ Java

Posted by Vivek on July 8, 2014

Purging messages is one of the common operations when working with queues.

MQI (Message Queue Interface) allows browsing/ reading the message by providing various calls (MQGET, MQOPEN etc) and options alongwith. Below is a sample code to traverse the messages in a queue and perform destructive read.

 

// Set the Get Message Options

int getOpenOpts1 = MQC.MQOO_INQUIRE + MQC.MQOO_BROWSE + MQC.MQOO_FAIL_IF_QUIESCING + MQC.MQOO_INPUT_SHARED

MQGetMessageOptions gmo1 = new MQGetMessageOptions();

gmo1.options = MQC.MQGMO_BROWSE_FIRST + MQC.MQGMO_NO_WAIT + MQC.MQGMO_FAIL_IF_QUIESCING + MQC.MQGMO_ACCEPT_TRUNCATED_MSG;

boolean msgPresent = true

while(msgPresent){

try{  

                def getMsg1 = new MQMessage();                     

                getQ1.get(getMsg1, gmo1);

                gmo1.options = MQC.MQGMO_MSG_UNDER_CURSOR    

                getQ1.get(getMsg1, gmo1);

gmo1.options = MQC.MQGMO_BROWSE_NEXT + MQC.MQGMO_NO_WAIT + MQC.MQGMO_FAIL_IF_QUIESCING + MQC.MQGMO_ACCEPT_TRUNCATED_MSG;                        

   }

   catch(MQException e){

if (e.completionCode == 1 && e.reasonCode == MQException.MQRC_TRUNCATED_MSG_ACCEPTED)

             {

                 // Same as expected

             }

             else

             {                 

               msgPresent = false;

             }

   }          

  }

Using SOAPUi to put/get message in/from IBM MQ

Posted by Vivek on July 8, 2014

We can use HermesJMS which provides out of the box feature to communicate with any of the messaging system. It comes with both soapUI open source and pro version. However, the drawback is message will contain JMS header and the responsibility of converting JMS to native header format lies with the developer/ tester. I have used IBM MQ as messaging system and in order to avoid any transformation from JMS to MQMD, I have used groovy to put and read messages.

Add a groovy test step to get hold of the XML message to be sent

def groovyUtils = new com.eviware.soapui.support.GroovyUtils( context )

def holder = groovyUtils.getXmlHolder(“AddDiscussionBoardItem#Request”)

log.info holder.getXml()

def xml = holder.getXml()

//Connect to the queue manager

// Queue used for putting message

def propIQueue = testRunner.testCase.getProperty(“inputqueue”)

//Queue used for reading message

def propOQueue = testRunner.testCase.getProperty(“outputqueue”)

 //setting hostname

def propHostname = testRunner.testCase.getProperty(“hostname”) 

MQEnvironment.@hostname = propHostname.getValue()

 //setting port

def propPort = testRunner.testCase.getProperty(“port”)

MQEnvironment.@port = Integer.parseInt(propPort.getValue())                       

//setting Channel

def propChannel = testRunner.testCase.getProperty(“channel”)

MQEnvironment.@channel = propChannel.getValue()        

//setting Queue Manager

def propQM = testRunner.testCase.getProperty(“queuemanager”)

def queueManager = new MQQueueManager(propQM.getValue())

//Put message in queue

 def putMsg = new MQMessage();

int putOpenOpts = MQC.MQOO_OUTPUT | MQC.MQOO_FAIL_IF_QUIESCING;

def putQ = queueManager1.accessQueue(propIQueue.getValue(), putOpenOpts);

putMsg.writeString(xml);

def pmo = new MQPutMessageOptions();

putQ.put(putMsg, pmo);

putQ.close()

//Read message from queue

def getMsg = new MQMessage();

int getOpenOpts = MQC.MQGMO_WAIT | MQC.MQGMO_BROWSE_FIRST;

MQGetMessageOptions gmo=new MQGetMessageOptions();

def getQ = queueManager1.accessQueue(propOQueue.getValue(), getOpenOpts);

getQ.get(getMsg, gmo);

def response = getMsg.readString(getMsg.getMessageLength())

getQ.close()

Deploying BAR (Broker Archive) using ANT

Posted by Vivek on July 7, 2014

This is not very straight-forward. WMB provide mqsideploy script to deploy the BAR file but before invoking the script, you need to source the mqsiprofile batch file. mqsiprofile is not a perl script and cannot be invoked directly. On windows platform, it is present in MQSI_Home/bin folder as a batch command file (.bat). This batch file has to run before mqsideploy.exe within the same script. Create a new batch command file (deploywmb.cmd) and add the following lines:

 

CALL “C:\Program Files\IBM\MQSI\7.0\bin\mqsiprofile.cmd”

CALL C:\Progra~1\IBM\MQSI\7.0\bin\mqsideploy.exe -i %1 -p %2 -q %3 -b %4 -e%5 -a %6

 

Where,

%1 corresponds to ipaddress, %2 corresponds to port and so on and are passed from Ant script.

The batch file is called and arguments are passed from Ant script as follows:

<target name=”deploy-bar”>

<property file=”${basedir}/build-properties/config/${Env}/DEMO.properties”/>

<property name=”bar-location” value=”${basedir}//bars//${Env}_${bar.file}.bar”/>

<echo message=”MQSI Deploy “></echo>

<exec executable=”C:\utilities\wmbbuild\deploywmb.cmd”

spawn=”false”

logError=”true”

vmlauncher=”false”

failonerror=”true”

append=”true”>

<arg value=”${ipaddress}” />

<arg value=”${port}” />

<arg value=”${queuemgr}” />

<arg value=”${broker}” />

<arg value=”${exegroup}” />

<arg path=”${bar-location}” />

</exec>

<echo message=”Deploying Broker Archive file – ${bar.name} ” />

</target>

Where,

${Env} is the environment for which BAR is created. Example – Dev, test, UAT

DEMO.properties file is the file for storing environment specific properties. The following properties are read from DEMO.properties file:

${ipaddress} is the name of the host of the Queue Manager

${port} is the port number of the listener

${queuemgr} is the Queue Manager name of the broker

${broker} is the broker name whose execution group is to be used for deployment

${exegroup} is the name of the execution group

${bar-location} is the location of BAR file which needs to get deployed

Posted by Vivek on July 7, 2014

We miss most of the jars in the classpath that give classnotfoundexception during operations related to WMB. Here is the list of jars required in MQ library to enable build and deployment of message flows on execution group:

com.ibm.mq.commonservices.jar

brokerutil.jar

com.ibm.mq.headers.jar

com.ibm.mq.jar

com.ibm.mq.jmqi.jar

com.ibm.mq.pcf.jar

ConfigManagerProxy.jar

MQOPEN options while reading/browsing MQ messages

Posted by Vivek on July 7, 2014

When using MQI, it is almost a possibility to read and browse messages. MQOPEN call precedes before accessing the messages and it is important to provide correct options before you do something with the messages.
For the options of the MQOPEN call:
v At least one of the following must be specified:
– MQOO_BROWSE
– MQOO_INPUT_AS_Q_DEF
– MQOO_INPUT_EXCLUSIVE
– MQOO_INPUT_SHARED
– MQOO_INQUIRE
– MQOO_OUTPUT
– MQOO_SET
v Only one of the following is allowed:
– MQOO_INPUT_AS_Q_DEF
– MQOO_INPUT_EXCLUSIVE
– MQOO_INPUT_SHARED
v Only one of the following is allowed:
– MQOO_BIND_ON_OPEN
– MQOO_BIND_NOT_FIXED
– MQOO_BIND_AS_Q_DEF

2013 in review

Posted by Vivek on January 7, 2014

The WordPress.com stats helper monkeys prepared a 2013 annual report for this blog.

Here’s an excerpt:

The concert hall at the Sydney Opera House holds 2,700 people. This blog was viewed about 8,400 times in 2013. If it were a concert at Sydney Opera House, it would take about 3 sold-out performances for that many people to see it.
