Message Broker (WMB) Integration with WSRR
1) First register the WSRR with broker. Follow the link below to register.
http://publib.boulder.ibm.com/infocenter/wmbhelp/v6r1m0/index.jsp?topic=/com.ibm.etools.mft.doc/ac56150_.htm
* In case using HTTP only all SSL related steps can be skipped.
2) Choose what node you want to use.
2.1) RegistryLookup node
Use the RegistryLookup node to retrieve any type of entity held in the WebSphere® Service Registry and Repository (WSRR). The entities that match the specified search criteria are stored in the local environment. The input message is not modified.
2.2) EndpointLookup node
Use the EndpointLookup node to retrieve service endpoint information held in the WebSphere® Service Registry and Repository (WSRR). The entities that match the specified search criteria are stored in the local environment. Depending on the node configuration, the Web service URL destination used by the SOAP and HTTP request nodes can also be set. The input message is not modified.
Good Sample and tutorials
1) http://www.ibm.com/developerworks/websphere/library/techarticles/0806_crocker/0806_crocker.html
2) http://www.redbooks.ibm.com/redpapers/pdfs/redp4558.pdf
Open Question: Consider a case when your WSDL is also stored into WSRR and you want to make WS call using WSDL stored in WSRR... how your WMB code would look like..

Health Conscious freak
Humm, sometime (or most of time, choose what you prefer) we do not have control on what we eat. To be honest, I like to eat a food which smells, looks and taste good, not based how calories in a food. Some freak people do, but most of the normal people do not. At the same time, this kind of attitude may be get you into big troubles which are not reversible sometime like diabetes, blood pressure problem.
I have been doing a lot of research on the food or food habits which can help us keeping healthy without making lot many changes in our food habits.
Milk
I was forced to drink milk in childhood. As I grew, it was free to choose, if I wanted to drink milk or not. Offcouse I choose NOT to drink milk. But let me tell you Milk is one of the best drink available (after dirty martini) which has everything which body needs. It is a perfect food. So one habit that should be adopted, is to drink Milk at end of the day before go to sleep.
Honey
Do you know Honey is more sweet then sugar? It is one of the best oxidant agent easily available. If you replace Sugar with Honey you can cut down lot of bad calories (fructose mainly). Honey has no fat, only high energy source of good sugar (glucose). Milk with honey can help you burn fat at night (being oxidant) also help you get some good sleep.
Stomach Holiday
Like other things stomach should also need an holiday once in a while so that we can also go and have some fun time :-). Kidding, well it might not go anywhere but still it needs rest once in while. Skipping dinner once in while gives time to stomach to recover itself. Trust me, you feel good next morning.
Eat Min 2 hours before Sleep
It takes body some time to digest the food and covert into energy. It is a good idea to give body sometime to digest the food before we go to sleep. So make sure to eat your dinner min 2 hours before you go to bad.
High Protean
Most of the time it is the carbohydrates which burns and produce energy, body is also capable of converting protean also into energy. Also protean is required to do all the repair works required in body. So it is always a good idea to eat lot of high protean contents foods like Eggs (Boiled), Soya, meat, fish
Grapes
Not sure about the name of the chemical but black grapes has this chemical which has anti-aging property. Consumption of black grapes are advisable time to time.
Wine / Brandi / Alcohol
Would advise people not to drink all the time, I am sure you are not going to listen. Drinking is good once in while. It kills around 75% of bad bacteria of body. But it should be taken as limited quantity and drinking is a bad habit.
Ghee / Butter
I used to think that butter is better then Ghee, then I did a google on this matter and result was quit otherwise. As per lot of comments Ghee is better then butter. The reason for that is butter has more unsaturated fat which are hard to digest where in Ghee has more of saturated fats which are relatively easy for body to digest. Also if you can go for Cow Ghee then Buffalo Ghee.
Negative calorie list for vegetables: The table below lists the foods which are supposed to have a negative calorie effect on the body. One thing to remember is that the body needs a certain amount of calories and nutrients each day for healthy functioning. Eating a lot more of these negative calorie fruits and vegetables may help you lose weight but they should still only make up part of a balanced diet.

Message Broker WMB
1) Create Broker
mqsicreatebroker BrokerName -i MQ_USER -a MQ_PASSWORD -q QM_NAME -n DB_DATA_SOURCE
2) Create Config Manager
mqsicreateconfigmgr CM_NAME -i MQ_USER -a MQ_PASSWORD -q QM_NAME
3) Trun On and Off Trace Node Output
mqsichangetrace –n [on off]
4) Broker Command queues
Request Queue
SYSTEM.BROKER.ADMIN.QUEUE
Reply or status queue.
SYSTEM.BROKER.ADMIN.REPLY
To Stop a flow send a message like this to command input queue.
------------------------Start----------------
<broker label="MB_5" uuid="fde5fa11-2101-0000-0080-ad643ef657b0" version="1">
<executiongroup uuid="94679f5c-2101-0000-0080-fcd728eb29b9">
<stop>
<messageflow uuid="dd732563-2101-0000-0080-a2d1ba771093">
</stop>
</executiongroup>
</broker>
5) Message CCID
1208 = utf-8
819 is a default Unix platform CCSID (819 = ISO-8859-1)
Constants
• MQCCSI_UNDEFINED
• MQCCSI_DEFAULT
• MQCCSI_Q_MGR
• MQCCSI_INHERIT
• MQCCSI_EMBEDDED
6) Encoding
• MQENC_NATIVE
7) MQ Output node once write the into Q the message property like New Msg ID (if set to be generated), Correlation ID would be written to Destination Data coming from out node.
8) WMB Flow testing.
A good WMB flow result testing tool. Good tool to do a broker flow regression testing. Easy to configure and use. MA0T tool here: http://www-01.ibm.com/support/docview.wss?uid=swg24007048
9) Tracing in WMB
Support pac to format and read the logs from WMB
http://www-01.ibm.com/support/docview.wss?rs=171&uid=swg24006480&loc=en_US&cs=utf-8&lang=en
Note: Should modify the bat file to 1) Specify the log file directory location 2)Delete the log files once trace is read from WMB.
9.1) Service Trace: Service trace is used to get detailed information about your environment for use by your IBM Support Center.
Activate service traces only when you receive an error message that instructs you to start service trace, or when directed to do so by your IBM Support Center
Start: mqsichangetrace {BrokerName} -t -e {ExecutionGroup} -l {log level debug|normal|none} -r -c 50000
Stop: mqsichangetrace {BrokerName} -t -e {ExecutionGroup} -l none -r -c 50000
Delete old log files: mqsichangetrace {BrokerName} -t -e {ExecutionGroup} -r
Trace Level Report: mqsireporttrace {BrokerName} -e {ExecutionGroup} -t
9.2) User Trace: Use user trace for debugging your applications; you can trace brokers, execution groups, and deployed message flows. Start user trace facilities using the mqsichangetrace command or the WebSphere® Message Broker Explorer
Start: mqsichangetrace {BrokerName} -u -e {ExecutionGroup} -l {log level debug|normal|none} -r -c 50000
Stop: mqsichangetrace {BrokerName} -u -e {ExecutionGroup} -l none -r -c 50000
Delete old log files: mqsichangetrace {BrokerName} -u -e {ExecutionGroup} -r
Trace Level Report: mqsireporttrace {BrokerName} -e {ExecutionGroup} -u
10) Collecting message flow accounting and statistics data
Message flow accounting and statistics data is the information that can be collected by a broker to record performance and operating details of message flow execution. Message flow accounting and statistics data records dynamic information about the runtime behavior of a message flow. For example, it indicates how many messages are processed and how large those messages are, as well as processor usage and elapsed processing times.
2 types of performance data can be collected.
10.1.1) Snapshot Data: Snapshot data is collected for an interval of approximately 20 seconds. The exact length of the interval depends on system loading and the level of current broker activity. You cannot modify the length of time for which snapshot data is collected. At the end of this interval, the recorded statistics are written to the output destination and the interval is restarted.
10.1.2) Archive Data: Archive data is collected for an interval that you have set for the broker on the mqsicreatebroker or mqsichangebroker command. You can specify an interval of between 10 and 14400 minutes, the default value is 60 minutes. At the end of this interval, the recorded statistics are written to the output destination and the interval is restarted.
10.2) Commands
Start: mqsichangeflowstats {BrokerName} -s -e {ExecutionGp} -j -c active -n basic
Stop: mqsichangeflowstats {BrokerName} -s -g -j -c inactive
Report Settings: mqsireportflowstats {BrokerName} -s -g -j
Delete Archive Reports: mqsichangeflowstats {BrokerName} -a -g -j -r
The trace reading support pac can be used to read the statistic in case usertrace option is used.
11) Sender / Receiver channel setup:
11.1) Sender MQSC Scripts
DEFINE QLOCAL(QM2) DESCR('Transmission queue to QM2') REPLACE +
USAGE(XMITQ) PUT(ENABLED) GET(ENABLED) TRIGGER TRIGTYPE(FIRST) +
TRIGDATA(QM1.TO.QM2) INITQ(SYSTEM.CHANNEL.INITQ)
DEFINE CHANNEL(QM1.TO.QM2) CHLTYPE(SDR) TRPTYPE(TCP) +
REPLACE DESCR('Sender channel to QM2') XMITQ(QM2) +
CONNAME('localhost(2414)')
11.2) Receiver MQSC Scripts
DEFINE CHANNEL(QM1.TO.QM2) CHLTYPE(RCVR) TRPTYPE(TCP) +
REPLACE DESCR('Receiver channel from QM1')
11.3) Some problems
1) Some time QMGR objects gets corrupted when you could not figure out the problem then. Delete Channels, restart QMGR and recreate Channels
2) One of the common problem is different CCSID of sender and receiver QMs. This is more likely to be a problem when msg from sender CCSID can not be converted to receiver CCSID by default MQ data conversion. e.g. from 819 to 1399. In case one of QM CCSID needs to be changed.
11.4) Some Scripts
1) ALTER CHANNEL(Channel Name) CHLTYPE(SDR) CONVERT(YES)
2) STOP CHL(Channel Name) MODE(FORCE)
3) DIS CHS(Channel Name) STATUS -- Status should be STATUS(STOPPED) not stopping..
4) start CHL(Channel Name)
mqsicreatebroker BrokerName -i MQ_USER -a MQ_PASSWORD -q QM_NAME -n DB_DATA_SOURCE
2) Create Config Manager
mqsicreateconfigmgr CM_NAME -i MQ_USER -a MQ_PASSWORD -q QM_NAME
3) Trun On and Off Trace Node Output
mqsichangetrace –n [on off]
4) Broker Command queues
Request Queue
SYSTEM.BROKER.ADMIN.QUEUE
Reply or status queue.
SYSTEM.BROKER.ADMIN.REPLY
To Stop a flow send a message like this to command input queue.

Linux Live
Linux is one of most dynamic OS. There are updates happening almost everyday. Linux Live is one of the feature which caught my eyes. I simpally liked it.
The idea of Live Linux is that you have a portable OS in your pocket in form of a USB stick. You can just put this USB stick in any machine and reboot, and there you go you have your own OS running. Though you have some restriction but still it is good.
Now you have option to try out all the linux flavor and choose the one you like most. I am sure all the linux flavours has something or other good, but I simple fan of Ubuntu. It gives all the flexiblity you can ask for.
- Small installer, require only one installer CD
- Smarter Updates, update your Ubuntu with what you want.
- Bigger software base, you will find all the things you need in the Ubuntu source archive, ranging from Dev Tools to multimedia, Good drivers for your hardware to simple UI.
Coming back to Live Linux. All you need a USB stick, installer for you Linux and Lili creator.(Do a google and you find the steps for installation)
Once installed you have max of 4 GB of space to make any updates to your OS. Looking from todays prospective 4 GB is less but that is a constain that I know right, may be I am outdated on this. Still you can have most of the stuff you need.
Now if you go some place and wish to show something to someone no need to carry your machine and because you know all the drivers / software are there, you are kind of sure that it would work.
It is a gift for people like me who kind of play around a lot with Linux and end up spoiling them. No worries just do the reinstall / simple restore the files from backup of USB stick and you are good to go again
