WAS: Resolution to Messages in the SIB locked forever

In a cluster where the messaging engine has failed over between nodes, a situation could arise where the transaction log (‘tranlog’) has become corrupt or is unrecoverable. In this situations, you may see messages on SIB Queues that are in the LOCKED state but are unprocessed. If you factor in a sequential delivering of messages, […]

WB552: Random DataPower Thoughts Part 3

“Root Certificates” are implicitly trusted. The lookup chain of certificates ends at a root cert. These are stored in the pubcert directory. sharedCert is where certificates that we share with other clients are located. When creating a domain, you should always include default as a visible domain. This allows access to the store:// file system […]

Use ARM to monitor SCA invocations in IBM WebSphere Process Server

This two-part series shows you how to monitor Service Component Architecture
(SCA) invocations using the Application Response Measurement (ARM) standard in IBM
WebSphere Process Server V6.1. You can use an ARM implementation, such as IBM Tivoli
Composite Application Manager for Response Time Tracking, to generate a graphic view
of SCA invocations. This article, Part 1 of the series, starts by describing ARM and
showing you how to debug synchronous scenarios using Tivoli Composite Application
Manager for Response Time Tracking. In Part 2, you’ll get an introduction to SCA
invocation patterns and learn how to debug asynchronous scenarios.

WebSphere Adapter for JDBC: SetObjectKeys NullPointer Exception

We had a WebSphere Adapter for JDBC export in our module, and it was throwing the following exception: [5/27/08 17:55:52:315 EDT] 0000006b NUXInResource I PollEventManagerWorker run() CWYBS0011I: Polling has started.

Business Object Maps and ‘Required’ Attributes

Just ran into an interesting scenario. We have a business object with a required attribute (amongst a sea of non-required ones). In a business object map, we only set the non-required ones and never set the required ones to any value. In the above example, ‘productStatus’ is required, ‘name’ is not. This is the Mediation […]

Web services with SOAP/JMS in IBM WebSphere Process Server

This two-part article series shows you how to use SOAP over Java Message Service
(JMS) in IBM WebSphere Process Server and IBM WebSphere Enterprise Service Bus. Learn
how to set up and use SOAP over JMS as configured by default by the IBM
WebSphere Integration Developer tool and how to enable the use of the IBM WebSphere
MQ JMS provider via configuration. In this article, Part 1 of the series, you create and
invoke a Web service using SOAP over JMS and an end-to-end application example, covering
the full process of creating, building, deploying, and testing the applications.
Scenarios covering both point-to-point and publish/subscribe messaging walk you
through the process. In the second article in this series, you’ll
reconfigure a Web service that uses the SOAP over JMS protocol to enable the use of
WebSphere MQ as the JMS provider and allow the transport of SOAP messages via
WebSphere MQ queues.

WebSphere Integration Developer: Visual Snippet Java Code Generation Is Non-Deterministic

I present the following exhibit: The only difference between these two snippets is the string that I am setting in the commonName attribute. But, let’s look at the java that was generated under the covers for the bottom snippet: boolean __result__31 = (iFlag != null) && (iFlag.trim().equals(“Y”)); if (__result__31){ commonj.sdo.DataObject svcCharVal = __result__34; java.lang.String __result__36 […]

Problem Determination and WebSphere Integration Developer

In the past, I’ve gone and de-constructed WebSphere Process Server stack traces in an example of problem determination. Now, I’ll talk about what I do when WebSphere Integration Developer goes crazy. A typical WebSphere Integration Developer exception consists of either a builder error pop up dialog or an issue when trying to open an editor. […]

WebSphere Integration Developer – Namespaces Cannot Span Projects

Say I have a Business Object named BO1, in the namespace “http://www.danzrobok.com/bo” and I have a second business object named BO2, in the namespace “http://www.danzrobok.com/bo”. With WebSphere Integration Developer, I MUST put both of these business objects in the same library or module project. If I split them into two library projects, then I will […]

WebSphere Process Server and RPC/Literal Web Services: Beware Messages defined by ‘type’ instead of ‘element’.

After a ridiculous amount of XML tweaking and bleeding, I realize that RPC/Literal truly is completely broken in WebSphere Process Server v6.0.2.3. On the response message that consists of a Business Object we would constantly get the exception: Caused by: org.eclipse.emf.ecore.resource.Resource$IOWrappedException: Feature ‘MyResultBO’ not found. (sca:/message.xml, -1, -1) The XML from the service looks correct: […]

WebSphere Process Server and an RPC/Literal WSDL : Trench War

I’m currently in a trench war with WebSphere Process Server and an RPC/Literal webservice. The service takes in a simple integer and returns a Business Object. The request works fine, but the response comes back with a ‘FeatureNotFound’ exception referencing the top level business object. I’ve even gone so far as to install SOAP UI […]

WebSphere Process Server Discussions

The first question kicked off about the use of BPEL for non-business relevant flows. The answer was that it’s not a good idea in the long-term vision and hard evaluation of Java or BPEL should be performed to ensure it’s the right solution. The lack of a store-and-forward capability in the product was the next […]

“Top Best Practices for Implementing WPS Solutions”

I haven’t heard of SIMM Levels before this presentation but they appear to be interesting statements about maturity. Talking about service quality, “You can’t mediate faster”. ISO9126 was also mentioned: ISO 9126 is an international standard for the evaluation of software quality. Don’t use relationships for configuration or rules. It doesn’t fit the use-cases of […]

WSDL Anti-Pattern: xsd:Any and xsd:AnyType To Encapsulate Future Changes

The cousin to yesterday’s WSDL Anti-Pattern: The ‘Single XML String’ Service is the use of the XSD specification’s ‘any’. ‘Any’ literally means “any well-formed XML contained in this section is valid”. ‘anyType’ means “any valid XSD Type”. We can start to see the correlation between the Single XML String service and the use of these […]

Avoid the WebSphere Integration Developer Debugger

Yesterday, I had a non-descriptive NullPointerException occur within a visual snippet sub-map in WebSphere Integration Developer. The only message written to the log was something that identified which transformation in the sub-map failed. There was nothing about what line was bad. Rather than filling my code full of “Got Here” and “Did this Runs”, I […]
