IBM Websphere MQ TIPS
websphere family.
MQ,MB,WAS,Portal
Features of MQ:
1) message delivery
2) Asynchronus messaging
3) Time dependent
4) Integrity
5) Support
Plat form independent
we can send messages from one os to other os.
A ——– B
solaris windows
TCP/IP SPNX
we can write our own code in any language.
JMS Supports Java language.
MQ is a s/w which is developed on java. but it supports all other languages.
it runs on eclipse palat form.
MQ version
dspmqver
ver 7.0 eclipse 3.3
ver 6.0
ver 5.2
ver 5.1
.
.
.
server
client
client with XA enabled. used for commit and roll back transactions.
Default 4MB info including header.
max 100MB info
300MB segmentation is required.
QM is like our weblogic domain
it contains all queues.
runs on a listener. default 1414 unless you define a port.
Queue types:
Remote Queue
Local Queue
Transmission Queue
Dead letter Queue
Alias Queue
Cluster Queue
Local Queue — where you store all the messages.
Remote Queue — Contains All the parameters of definations
It will not store any messages but it will send the messages to local Queue.
Sender recvr — names should be same
surconn — We use surconn to send the message from the application to MQ.
client A ——-> server B
surconn
Below parameters are required to connect to the client
Qname
servername
port
protocol
#dspmqver ( it will display MQ version)
command not found ( MQ is not installed)
Before installation you Make sure that the below dir are exist
/opt/mqm ( all the binaries generated from installation)
/var/mqm ( all the configurations and log file )
Before installing MQ Execute licence file
cd /opt/mqm
./mqlicence.sh
check whether mqm user exist or not
more /etc/passwd | grep mqm
++++++++
#group mqm
mqm unixadms wheel
#pkgadd -d /home/melletit (used to install any s/w in solaris)
execute steps 1,2,3
select below options for MQ installation
1) MQ server
2) Man
3) sample programs
4) mq client
5) IBM jre
6) extended Architecture
enter : 1,3,5,6
cd /opt/mqm
ls -lrt
cd /var/mqm
ls -lrt
#crtmqm QM.DEMO ( create Queue Manager)
#dspmq ( It displays QM status )
#dltmq testqmgr ( delete QM)
#strmqm QM.DEMO ( Start Queue manager )
#dspmq ( displays QM status)
#cd /var/mqm
#more mqm.ini ( Contain all the configuration details of QM )
#cd /var/mqm/errors ( Contains installation error logs)
.FDC ( Contains network issues )
$ffstsummary
The tool ffstsummary is also useful – it produces a summary of FFST reports in the current directory, sorted into time order. This can be a good place to start to see the errors reported in your errors directory.
For example:
[dalelane@dlane ~]$ cd /var/mqm/errors
[dalelane@dlane errors]$ ffstsummary

#cd /var/mqm/qmgrs/QM!DEMO
more qm.ini ( Contains all the details of particular QM – log, Services, service components)
logfile types
1) circular logs — Info cant be retrived. It will overwrite previous logs.
2) linear logs — Will keep on appending the log file. ( use for production )
based on criticality of message we will decide the log types.
logpath = /var/mqm/log/QM!DEMO
cd /var/mqm/log/QM!DEMO/errors — give the errors to the particular QM.
cd /var/mqm/log/QM!DEMO/active — we can check QM is active or not. Some times due to pending message QM goes into inactive state.
#runmqsc ( used to run mq commands )
There are two ways to configure the objects in MQ
1) command line
2) console
#runmqsc QM.DEMO
AMQ8426: Valid MQSC commands are:
ALTER

Trouble shooting & Interview questions:
***************************************
1) What is Remote Queue? and Remote Queue parameters
2) Reasons for message is going to retain state.
1) Not able to get the connection
2) Input parameter for remote queue might be wrong ( parameter)
3) Destination QM is not running
4) Sender and REcv channel names should be same ( might be wrong some time)
5) Message will be in local queue
6) Problem with message format
xmit Queue properties-> put : allowed
get : allowed
Local Queue -> usage : Transmission becomes Transmission Queue.
Dead letter Queue (DLQ)
***********************
1.IF destination is not defined or unavailable then message without loss it will store in DLQ .
each queue manager (QM ) will have one DLQ .it is mandatory or suggested to have DLQ .
QM.DEMO QM.DEMO1
|->DLQ1
|->DLQ
RQ LQ
TX Receiver channel.
SC (sender channel)
Before sender channel started message seats with or stores in TX .
once connection established it will reached the receiver channel and look for destination queue .
if that moment it will not able to find the destination queue it will store the message in DLQ1(which is with Qmgr )

deadletter handler :program will helps in retriveing the message from dlq to destination queue.
if destination queue is fulled then receiver channel drop the msg into DLQ .
input count : no .of threads connection to local queue to put the msg . (put )
output count : get
always check mq logs .
if message flow is not happening then check following points;
1. MQ logs.
2. destination properties
3. channel is active …
4. application security issue ……(proxy)

what is OSB?
OSB is a shared domain and used for transformation and routing like Message Broker in Websphere.
OSB requires Weblogic.
MB requires MQ.
