Yesterday I received the announcement of the new Oracle WebLogic 12c, on the 1st of December 2012. You can register for a webcast on
So, what’s there to be expected. Personally I think WebLogic has been made Exalogic ready, according to Mike Lehmann, Director of Product Management for Oracle WebLogic.
Some of the few features I expect:More Â Exalogic features like:
- Parallel muxers with Java NIO APIs for low-level I/O based operations
- An optimized work scheduler providing improvements to the IncrementÂ Advisor used to manage the size of WebLogic Server’s Self-Tuning Thread Pool
- “Lazy” de-serialization of session data on the replica server until required.
- Multiple replication channels for synchronous in-memory session replication betweenÂ servers in a WebLogic cluster
- Adjustments for supporting the Â Infiniband and SDP
Some people were asked to review my book, here are some links:

Years ago, when I worked as an Application Support Analyst for a big triple-A Bank, I got acquainted with the BEA product stack.
One of those products was BEA Tuxedo, at that time at the release of 6. I worked at a settlements project, and Tuxedo was used for as distributed transaction processing, to process settlements an clearing messageg from the bank to an international Clearing an Settlements Project, called CLS. It used the SWIFT network to connect; CLSÂ was an international and timezone independent settlements and clearance platform to overcome timezone and bankrupt issues, and prevent a domino effect when an important bank in the chain becomes bankrupt.
Tuxedo is a transaction processing system or transaction-oriented middleware, or enterprise application server for a variety of systems and programming languages.
Tuxedo was designed for high availability and to provideÂ scalable applications to support a lotÂ transactions per second on commonly available distributed systems. It was developed and designed by AT&TÂ if that required online transaction processing (OLTP) capabilities.
Tuxedo is aÂ message routing and queuing system. Requests are sent to named services More >
This week, I went on an invitation of my publisher Packt to Oracle OpenWorld, to be present on the launching of my book, Oracle WebLogic 11gR1 PS2: Administration Essentials.
While busy dropping some tweets, I noticed a tweet mentioning my book; I opened the link and what did I see? An article on the San Francisco Chronicle online version, about the announcement form Packt about the publishing of my book.
So now, I’m waiting for the limo taking me downtown to SFÂ … well, it didn’t show up so I took BART to downtown SF. Bit still a neat thing to see you name in a local paper!
Here’s the article:
My book will be presented at OOW, tuesdat the 4th of october 2011, atÂ Oracle’s Publisher Seminar, Hotel Nikko in San Francisco!
A great tool within Oracle WebLogic Server is the WLDF ( WebLogic Diagnostics Framework). Before 11g deliverd as an extension, but now integrated into the Console, It delivers a framework for monitoring your entire WebLogic Server with monitoring capabilities through MBeans.Out of the box, the WLDF console delivers some basic views, but if you’d like to extend the monitoring capabilities, here’s a way to do this.
First of all, your WebLogic uses watches to monitor all kinds of things to see how you system is performing, but not all watches are running. In this example, we would like to see how the CPU’s are holding under heavy load during testing.
Our Oracle WebLogic runs on a AIX LPAR p690, version 6 64 bits O/S.
First we need to create a watch to pick up notifications about the state of the CPU.
In the Admin Console, section Domain Structure, click on Diagnostic Modules to create a new Collected Metric
