Securing JMS connections to WebSphere Enterprise Service Bus V6.1

syndication — Wed, 04 Mar 2009 17:00:00 +0000

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.

WebSphere Process Server Disaster Recovery: UUIDs are unique to an install

dan — Tue, 03 Feb 2009 16:05:11 +0000

If you are looking at WebSphere Process Server Disaster Recovery, you should know that the UUID’s that uniquely identify a server in both the Messaging Engine Database and the transaction log are unique for that particular installation. Running the equivalent installation commands on the restored system will not generate a server with the same id. [...]

Establish a policy-driven SOA using WebSphere Service Registry and Repository and WebSphere ESB

syndication — Thu, 09 Oct 2008 16:00:00 +0000

The WS-Policy specification provides a simple language for expressing policies supported by Web services. IBM WebSphere Service Registry and Repository supports loading, changing, and retrieving policy documents, and also supports using policy attachments to link a given policy with a service. This can then be used by a run time component, like an Enterprise Service Bus, to retrieve defined policies for a particular service or operation and act accordingly. This article shows how you can utilize standard WS-Policy documents stored in a registry to impact run time behavior in an ESB -- and then change that behavior on the fly with no code changes or redeployment.

IBM Installation Manager Tip: Don’t “Save Files For Rollback”

dan — Mon, 07 Jul 2008 19:41:32 +0000

The ability to roll back a update is a nifty idea. The theory is that you installed something that broke your platform. You can now just ‘undo’ the install. In practice, it’s a feature that next to nobody uses. It requires a deep-faith in the programmers of the rollback logic to return the system to [...]

WebSphere Integration Developer Upgrade from 6.1 to 6.1.2 – Two Hours

WebSphere Adapter for JDBC Export and SQL Server 2000: Table Locking while Polling

Tip: WebSphere Process Server – Do not delete the ‘tranlog’ on a production server

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 [...]

Web services with SOAP/JMS in IBM WebSphere Process Server

syndication — Mon, 26 May 2008 16:00:00 +0000

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.
