With the new decision service, governing and deploying your rules is simplified and accessible to use. A Decision service is a new management unit that allows complex decisions that involve several rules projects to be managed as one single entity. The decision service comes with deployment configurations, allowing rule changes to be deployed by business users for better testing and impact analysis.   A new interface in the Business Console enables business users to define and run their own tests suites with full autonomy. They can... [More]

  Are you planning to upgrade your level of z/OS or WebSphere Application Server, or maybe even both, and are wondering how one might affect the other? The Software Product Compatibility Report will help you figure this out:   http://publib.boulder.ibm.com/infocenter/prodguid/v1r0/clarity/index.jsp   The first page you will see is this:   You can select 'High-level' or 'In-depth' reports. The High-level report is sufficient if all you want to see is what maintenance level of the Application Server for z/OS is compatible with the... [More]

  Sometimes, during the course of testing or troubleshooting, we need to really understand what is going on in the depths of the WebSphere code when our enterprise application executes it's logic. When the basic log output from the server does not provide enough data to surmise what the root cause of the problem is we must then collect verbose tracing data from the server in hopes to capture the sequence of events that are occurring (or not occurring) while the application is running. This is where reference traces can become... [More]

  Concerns when connecting mobile clients to DataPower through HTTP(S) A common use case is to secure web services for mobile clients by using DataPower to proxy HTTPS from mobile clients. This has some challenges.   Here is one: By default the idle client timeouts for most services are 2 minutes. Of course for a mobile client that is almost always much too long. Would you wait 2 minutes on your phone for a app to respond or a web page to download?   By itself though, this would not be an issue. However, unlike fixed clients,... [More]

  There are so many times when CICS Transaction Server (CICS TS) will put out a DFHxxnnnn message stating "An Abend (Code 0Cn/AKEA) has occurred at offset X'nnnnnnnn') in program/module xxxxxxxx" where the offset is X'FFFFFFFF'. Have you ever wondered where does this offset of X'FFFFFFFF' come from?   Here are just some of the examples of what you might see: DFHSR0001 An abend (code 0C7/AKEA) has occurred at offset X'FFFFFFFF' in program user program. DFHAP0001 An abend (code 0C4/AKEA) has occurred at... [More]

  In my tenure with the IBM WebSphere Foundation SWAT team, I've seen many scenarios in which clients, unfortunately and for lack of a better term, shoot themselves in the foot either with the products they use or with their processes and design choices.   To bring about awareness of these scenarios, the SWAT team wrote a guide in 2009 that exposed these malpractices and explained how to mitigate them to avoid these costly mistakes, saving the business bottom-line. In 2013, we started a project to re-write the document, the result... [More]

  How to cache all your stylesheets: This is a useful trick for several reasons. If you are curious to see how much memory all of your compiled stylesheets could possibly use, here is a (relatively) quick way to find out. Also, with some modification, this could be used as a startup script to precache your stylesheets to improve user latency when the device is first put online.   Assume you have a backup of the device, such as all.zip. From a linux CLI: - mkdir all - cd all - unzip ../all.zip   Now remove the default domain, we... [More]

  A little used feature of the IBM WebSphere DataPower Appliances XI52 & XB62 is the MPGW POP FSH (Multi-Protocol Gateway - Post Office Protocol - Front Side Handler). This FSH can pull (or poll) mail messages from a POP server to be processed by the MPGW or a B2BGW. While normally used as part of a B2B (business to business) setup; it can also be used stand-alone as a normal MPGW FSH. This poller though is slightly different from the other pollers, such as the NFS poller or a MQ poller. Those handlers will all perform roughly the same... [More]

  I think we are well over due for a new update on What's Hot in the WebSphere MQ World. It is Spring time here in the United States and several things have been springing up in the WebSphere MQ world lately. I think now is a good time to talk about a few of them.   1. How the TLS Heartbleed security vulnerability applies to WebSphere MQ offerings. This topic has been a hot item recently for most all companies. Whether this vulnerability actually affects a product or not, it is still a hot topic, even if it is just a matter of... [More]

  The web User Interface (Web UI) in IBM Integration Bus (IIB) V9 is gaining a lot of ground as its capabilities are increasing. Web UI offers several features to broker administrators for administering broker resources.   1. Starting and stopping resources such as Integration servers and message flows: You can select the resource and click the inverted triangle symbol to invoke the start/stop option as shown in Figure 1 below. Figure 1   2. Enabling and disabling message flow accounting statistics: You can select the concerned... [More]

  Once your application is implemented and deployed, it is important to keep it up-to-date and maintained to avoid any issues that might impact its availability and to ensure continued support in the event a problem occurs.   The Operational Decision Manager version numbers use the standard IBM format V.R.M.F which stands for Version.Release.Modification.Fixpack . See the V.R.M.F Maintenance Stream Delivery Vehicle terminology explanation for more details.     First of all, it is always... [More]

  Some clients report an uneven distribution of messages from the queue manager to WebSphere Application Server (WAS) activation specifications in a MDB (Message Driven Bean) cluster. It may seem that most of the work being done by the application is on one WAS server in the cluster. Consequently this can cause one of the JVMs to be overloaded and experience CPU starvation.     If the version of the WebSphere MQ queue manager is between 7.0.0.0 and 7.0.1.5, you may be able to resolve this by applying a fixpack.   In...

  It used to be that formatting a CICS Auxiliary Trace dataset meant submitting batch jobs to run the trace formatting utility DFHTUxxx. MANY batch jobs.   First a run to get the abbreviated trace, so you could see what the time range the trace dataset covered, and perhaps get some task numbers. Then another run, limiting the time range or task numbers formatted to ones you were interested in. Then yet another job to format only selected trace entries.   I was pleasantly surprised when I recently discovered that the IBM Fault Analyzer product... [More]

  Working in CICS level 2, we see a variety of different problems that are related to threadsafe issues. Specifically, where a program is marked threadsafe, but is really not. These can cause unpredictable results, and can be difficult to diagnose.   One common problem is where a program is marked threadsafe, but contains an assembler routine that uses static storage for a register save area. This now exposes a problem where 2 different tasks, running on different TCBs could be in this program at the same time, saving their registers in this... [More]
