A technote was published for customers who use the WebSphere Adapter for JDBC for inbound processing of an SQL Server 2000 database. Apparently, the adapter will lock the entire event table (bad!). The ‘fix’ aka workaround is to use a view to the event table and then set a custom property inside the adapter.
In development mode, one of the steps to ‘clean up’ from a wonky process server instance is to delete the wstemp, temp directories along with the ‘tranlog’. The ‘tranlog’ is an internal file that WebSphere Application Server uses to manage in-flight transactions and attempt to recover them should the server crash. When you delete the […]
A handy resource for seeing what exactly is contained in a new release of software are the APAR fix lists published by IBM. They contain a list of every APAR that is resolved and you can click to get more information. You can find them for: WebSphere Application Server 6.0.2 WebSphere Application Server 6.1 WebSphere […]
We’re battling another runtime problem. We’re on 126.96.36.199 and WAS 188.8.131.52 and have a situation where our modules that enable Event Sequencing seem to deadlock when trying to pick messages up off the queue. The transactions then time-out in a sea of exceptions. We have a messaging engine cluster (set to 1 of N) and […]

A web application firewall can provide a service over both http and https without requiring the use of a multi-protocol gateway.
A while ago, I posted about the WebSphere Adapter for JDBC always writing an exception to the System.out when a record could not be found. At the time, we were being told that it was not something that would be fixed in the 6.x timeframe. Suddenly, there has been a change of heart from IBM […]
“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 […]
I had a custom snippet in my map between two string attributes and a list of business objects. The idea being that each string from the source should becomes an entry in the business object list with a wrapper. No problem. I wrote up the snippet to create the destination business object (since it does […]
Learn how to use the thread dump facility in IBM WebSphere Application Server V6.1 to
learn about your system environment, investigate whether a deadlock is
happening, and extract information to help you avoid or resolve deadlock
situations with your own applications.
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.
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.

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 […]
