Complexity is is entropy
Comprehensive article from Infoworld surveying the modern software stack and the increased level of complexity inherent in today's systems.
Some WebSEAL notes
Reviewing interoperation with IBM MQ
A couple of random tips...
- To save an html as a PDF and preserve links, open the page with an Opera browser and "Save as PDF".
- To delete all text between two patterns...
sed -n '1,/<body>/p;/<h1/,$p' $i
What type of cloud to choose
Public, Private, Hybrid, Multicloud, Distributed Cloud - Which one is right for you?
Configure traditional WAS on OpenShift
For info on how to move WebSphere ND to cloud, see: Cloud Pak for Applications: Operational Modernization Solution. Also see, tutorial on how to Configure traditional WebSphere session persistence on OpenShift. Here are steps to create customized, curated container images of both traditional WebSphere Application Server (tWAS).
Azure Red Hat OpenShift
Here is a comprehensive set of examples for implementing Azure Red Hat OpenShift leveraging WebSphere Liberty.
According to Forbes, the current highest-paying certifications are Google Certified Professional Cloud Architect, CISM – Certified Information Security Manager and AWS Certified Solutions Architect.
IBM is splitting it’s Global Services division into a new company in order to concentrate on Cloud. It appears WebSphere Application Server is considered as part of their Cloud offerings:
IBM’s detailed documentation on Red Hat OpenShift on IBM Cloud has lots of practical examples and inline links.
Reading Kurt Cagle’s article Beyond Agile: The Studio Model.
One significant flaw in Agile is that it is programmer-centric and task-oriented. However, a significant portion of any project relies upon existing resources and SMEs who serve to to curate, annotate and document the institutional information that are necessary for projects to succeed. They are the ones that end up documenting code and make information consistent, findable and describable within a common metadata framework. These are ongoing processes, which IMHO have always fallen outside of most Agile frameworks, yet as enterprise consistency becomes an ever larger requirement, the role of librarians and data stewards becomes much more pressing.
Getting caught up on Job Manager tooling, which lets one asynchronously run WebSphere and host-level jobs on remote servers.
Here are some notes on a portal performance tuning project I completed a few years ago.
Some notes on common DB2 database commands.
I have posted some notes on a security hardening session. Notes are specific to WebSphere Portal v8, but are generally applicable to other apps deployed to WAS.

We can display the name of the cell, node, and server in front of the output for the ps -ef command by setting the cell custom property…
com.ibm.websphere.management.launcher.options = displayServerInFront
The IBM DataPower XI52 appliance provides an ESB backbone that facilitates (brokers) communication between services. Features include…
||Communication between parties who use different protocols such as http, https, ftp, MQ. ESB bridges (converts) these protocols.
|Message format virtualization
||For example, one party sends XML (SOAP) message, ESB converts to JSON, which is sent to backend.
||WSDL services that used to exist on servers can be moved to ESB.
|XML attack security
||Including DoS, MMXDos, and other attacks.
|Configuration driven interface
||Less code to write
|XML processing at wire speed.
||Versus server-based ESB solutions that operate at software speed.
Here are some basic wsadmin script examples.
Here are some project notes created when I was the WebSphere Commerce administrator for a large Fortune 500 retailer. The notes discuss integrating WebSphere eXtreme Scale DataPower XC10 appliance with WebSphere Commerce.
If you need a quick and easy network sniffer give snort a try.
We can leverage SSH public-key authentication between hosts to enable all sorts of useful functionality, including…
- Password-less login from HostA to HostB
- Ability to execute remote commands from HostA on HostB
- We can automatically administer an entire network of servers from a central server
I once set up a large WebSphere Commerce site for a Fortune 500 retailer that used this procedure to remotely execute various commands, including stopping/starting, and generating reports for, eXtreme Scale caching.
