If you plan on using datapower to write a modified value to the AppIdentity MQMD header, ensure that your Put Message Options on your destination are correct.

You want to use “2052″ which represents “MQPMO_SET_CONTEXT_ALL” along with “MQPMO_NO_SYNCPOINT”. You need to tell MQ that it should use the message headers from the written message. In Datapower, (for some unknown reason) in the URL Builder for MQ, this is the “User Identity” on/off toggle.

‘No Syncpoint’ tells MQ that this is a single message transaction that isn’t dependent on the writing on subsequent messages. This of it like “I want all 5 messages I write to the queue to be committed all together or none at all”.

If you don’t set your Put Message Options correctly, you won’t see your modified headers written onto the message in the Queue.

I was using WTX 8.3 to build a type tree off a COBOL copybook. When I then attempted to run a map based on the tree I got the error “One or More Inputs was Invalid”.

My Input data was in EBCDIC format and RFHUtil was my saviour. It was able to display the copybook and the data side-by-side so I could see what values should be where. (Sidenote: Good EBCDIC editor is VEDIT ).

I turned on Map Tracing via the not-well-defined ‘Map Settings’ and InputContentTrace and saw that my data wasn’t matching up with the items in the input. It was trying to put data contained in byte 1000 into an object defined at byte 1050.

Then I noticed that the number of bytes that my imported data in WTX was ‘off’ was the exact same number of bytes as a group.

I opened the Generated type tree and sure enough, a group was missing. Once I added it back as a Child Component in the Root ‘Record’ group (along with a few other missing groups) my input successfully validated.

Now, I don’t know a ton about the structure of cobol copybook or what could have caused it, but if you are in WTX and don’t see your input data lining up properly it’s probably because your WTX Root Object is missing them.

Just had a problem where a WSDL file that was uploaded to the DataPower device did not show up in the local:// drop down for selection.

Upon further inspection, we found that there was whitespace before the
<? xml .. ?> tag and whitespace before the <wsdl:definitions...> tag.

Once this extra whitespace was removed, the WSDL appeared in the drop downs and worked fine.

I’ve posted a question to the Datapower external newsgroup asking about how Siteminder can be used to authenticate users. The documentation is pretty thin on the subject.

https://www.ibm.com/developerworks/forums/thread.jspa?threadID=315235

Basically, i have a username and password that I’d like Siteminder to authenticate. I’m sure that Datapower invokes a URL and posts the information to the given URI. It then inspects the response cookie and determines if Siteminder was successful.

The usual Siteminder usage pattern is for someone to hit a page with a web browser and then be issued a challenge.. So it’s possible Siteminder requires this step into order to validate.

From Developerworks, Migrating to WebSphere Process Server V6.2 This tutorial shows you how to migrate WebSphere Process Server configuration data, application data, and databases from V6.1.2.3 to V6.2.0.1. The tutorial also describes the sub-tasks involved and shows you how to use migration log files for troubleshooting. Everyone's favourite task: Migrating between versions.

If you are planning on upgrading your WebSphere Servers to a later fixpack level, be sure to start with the Deployment Manager. If you do not, your Deployment Manager will not be able to contact your ‘future level’ node agent.

“Server cannot be started because the node agent for server Node1 on node x is not active”

Attempting to call syncNode to the deployment manager will result in:

ADMU0127E: The version of the Deployment Manager is earlier than that of this node. Deployment Manager version earlier than that of a node is an unsupported configuration.Upgrade the Deployment Manager to the same or later version as that of the node.

You will need to know about the Sequence object when dealing with

• xsd:any
• xsd:anyType
• xsd:anySimpleType
• xsd:anyAttribute

This used to be completely undocumented and now, the documentation is actually really good. Enjoy your undefined datatype.

I still stick with the rule that undefined types are the scourge of good integration.

AlbeesOnline has posted a great article showing how difficult integration projects can be when you need to work with teams spread across an organization. A relatively straightforward project turns into a Frankenstein of text files and workarounds. It also shows the reason why projects have meetings that involve 20-30 people five times a week, you miss a department and they’ll pop up out of nowhere and tell you what you are doing is impossible.

I have to admit that I die a little inside when I hear of projects that have to switch from clean-elegant solutions to crazily complicated ones to work around corporate policies. The customer gets the final solution and wonders why the heck they bothered with an integration platform in the first place. It’s depressing.

From DeveloperWorks, Securing JMS connections to WebSphere Enterprise Service Bus V6.1

Security is an integral part of SOA, and since WebSphere ESB is at the heart of many SOA solutions, the security of a WebSphere ESB server and its transports is vital to the enterprise systems that use it. Messaging, such as the JMS implementation provided by WebSphere ESB, is particularly important for business applications because of its reliability, performance, and asynchronous nature. This article shows you how to implement security with an example using WebSphere ESB V6.1 and a J2EE client container application communicating via JMS messaging.

Securing the messaging engine is a task that most customers need to do but documentation of all the steps was hard to come by. This article puts them to light to make the entire process easier.

If you would like to specify a constant value for an XPath Duration (used in a wait activity or an escalation) you can follow the format specified by the w3 consortium for durations.

The lexical representation for duration is the [ISO 8601] extended format PnYn MnDTnH nMnS, where nY represents the number of years, nM the number of months, nD the number of days, ‘T’ is the date/time separator, nH the number of hours, nM the number of minutes and nS the number of seconds. The number of seconds can include decimal digits to arbitrary precision.

Weirdly enough, the duration needs to start with a ‘P’.

Also, if you are in the WebSphere Integration Developer editors, ensure that your constant is contained within single quotes.

'PT2M'

as opposed to

PT2M

The latter will cause the runtime to look for a child element named PT2M.

Uninstalling or updating the WebSphere V6.1 test environment using Installation Manager; Update Failed.

If you try to update your WebSphere Process Server Unit Test Server from 6.1 to 6.1.2, you may run into an error. This can occur because updates have been applied to the server outside of Installation manager. Basically, WID’s Installation Manager and WPS’s Update Manager are out of sync with each other. This document explains how to fix the problem.

It is also noted that this synchronization issue is fixed in 6.1.2.1.

As usual, ensure you read the appropriate update documentation before attempting any upgrades.

From DeveloperWorks, Managing tasks and business processes using WebSphere Business Space:

Learn how to create WebSphere BPM V6.1.2 Business Space dashboards using the run-time artifacts from the WebSphere BPM V6.1.1 Clips and Tacks tutorial. You'll create a business space to manage the tasks and business forms input, run some processes that use forms, and finally create a business space you can use to monitor the process and tasks.

A good resource if you'd like to know more about what a 'Business Space' is.
