Technical support knowledge for Application Integration Middleware including WebSphere, CICS, BPM, MQ, Broker, IIB, ODM, DataPower, Mobile, Appliances, and more! Following the IBM Social Computing Guidelines - Steve Webb, William Wentworth, Joseph Lam
So you tried out the Business Rules Service on Bluemix , and you are wondering why you should stick to ODM .
You have a good point there.
Except, maybe you don't. It really depends.
That's not really an answer you say.
To start with, lets outline what Business Rule on Bluemix provides, and what it doesn't.
Number one: you have to be okay with less control.
I repeat, you have to let go.
Now if you are one of those type A personalities... [More]
If you have worked with and are a fan of IBM ODM (who isn't?), you should give the Business Rules Service on Bluemix a try. You should try it out even if you just typed “ODM” in Google search.
Wait, what are business rules again? And since Wikipedia was not very helpful, what does ODM do?
Businesses define repeatable decisions or policies that govern their operations. What this means is they define certain rules to live by to earn money (or try to not lose money at the very... [More]
The WebSphere L2 Support team handles its fair share of WebSphere Application Server performance analysis. Often it appears as though the Monitoring Agent (that thing that reports whether the system is behaving - or not) is the problem itself. The truth is, the more problems that the agent has to report, the more noise the agent is going to interject into the diagnostic data. It's a vicious cycle.
One of the common agents that are encountered is Wily. Like any performance monitoring tool, Wily can introduce a... [More]
The Internet of Things is all around us; any object that can be assigned an IP address and provided the ability to transfer data over a network is part of the Internet of Things (IoT). Every day a multitude of intelligent IoT devices are being manufactured, shipped and deployed to add to the billions already connected to the internet.
Not only does every man, woman, child, and pet potentially have an intelligent device, there also exists machine-to-machine communication between chips and sensors embedded into... [More]
List of firewall ports that must be open for communication between the deployment manager, nodeagent, and Application Server
It's very important to know the ports that should be opened in the firewall for proper communication between deployment manager, nodeagent, and application servers. Follow the below steps to achieve this task.
Find the port numbers in the serverindex.xml file or from the ISC (Integrated Solution Console)
The serverindex.xml file can be found under the... [More]
Occasionally when reviewing a heapdump that was generated from an out of memory event, the largest consumer of heap memory may consume slightly more memory than the other objects. Because of this, WebSphere users and moderators may incorrectly accuse the largest heap consumer as a memory leak.
If a Java™ heap is sized too small, an out of memory error will occur regardless if a memory leak exists. The leak suspect shown in IBM HeapAnalyzer or Memory Analyzer (MAT) will show a java object... [More]
The transaction timeout value can be set in the application component or in the administrative console for WebSphere Application Server (WAS). If the application component does not specifically set its own transaction timeout, WAS will timeout a transaction according to the 'Total transaction lifetime timeout' property. This property is the default maximum time allotted for a transaction to complete before it is timed out. If completion processing is not started on the transaction before this timeout value is reached, it... [More]
PCF messages are unique within WebSphere MQ because they help to solve problems like remotely administering an MQ network as they grow and thus become more complex. Remote administration through their use helps to centralize task execution and can help with resource management, object manipulation, and performance monitoring just to name a few.
The product documentation in the IBM Knowledge Center provides some great reference material on the topic. Its chapters contain detailed information on these messages and... [More]
DataPower caches will re-validate an expired cache entry before returning the data. This usually consists of an HTTP(S) HEAD request to the origin server. While debugging a client's issue I found an interesting wrinkle about these requests:
the request will always set the Connection: close header
you cannot add custom headers through the user agent or any other means to this request
though you can set basic authentication headers
If for some reason your HTTP server needs... [More]
If there is no cell default certificate SSL setting, then JSSE will pick one.
To set a default do the following:
In your Deployment Manager environment, logon to the Admin console.
Go to Security --> SSL certificates and key management --> manage endpoint security configurations.
Under inbound, select the entry that contains your cell name followed by "(CellDefaultSSLSettings,)".
Next click on update certificate alias list under SSL configuration.
Hermann recently found a new trick for when dealing with binary transform actions & preprocessed (non-xml) rules.
Normally, when the message type is preprocessed the actions cannot access the input content. But there is a simple workaround:
add new INPUT--Results--__INPUT action as very 1st action to rule
have __INPUT instead of INPUT as input action of xformbin action
This way you have a copy of the input data to read or manipulate.
Bluemix is a new Platform as a Service (PaaS) cloud offering from IBM. With Bluemix, you can have a free trial that can then later be converted to a pay-as-you-go account. If you are not familiar with PaaS – one of the best explanations I have seen is the comparison to “pizza as a service”.
The graphic above, originally posted by IBM's ⇒ Albert Barron helps distinguish the differences from traditional on-premise to Platform or Software as a service. Similar to... [More]

Can applications talk? Can computers talk? Can humans talk? Yes? OK. Let us agree on that one. At least most of us have the ability to talk. Why do we talk? Well, one definition of talking, is “to communicate or exchange ideas, information, etc. by speaking.” Great! Now we are faced with yet another word, speaking. Speaking is “articulating sounds with the ordinary voice.” So, without getting lost in definitions, talking involves exchange of... [More]

There are so many influencing factors and levels of communication. Just because you said it does not mean whoever you are speaking to understood it. Have you ever been in a crowded and noisy place, trying to talk to a friend? What happens to me sometimes is that I do not hear what my friend said. So I just smile and hope it was not a question. Not the perfect way, I know. But if you have been screaming the whole time and your throat already hurts, you just go for the... [More]
No source displayed in CICS debug session.
This is a problem I come across quite often. There are several steps a developer can do to resolve the issue before calling IBM for help:
current program loaded is not prepared for Debug Tool
This can happen if the program is not loaded from the expected library. CICS found an older / different version of the program first in the DFHRPL search path. Issue DESC LOADMOD in the debug session. Here is an example of the output:
