Exalogic Networking Part 1

This is the first blog entry in a series I will be writing on Exalogic Networking. The entries will start with the low level basics and work their way up to architectural strategies for the partitioning and configuration an Exalogic Rack.

This first entry will look at the low level creation and configuration of vNICs, vIPs, vLANs, BONDs and how we can leverage scripting and the dcli command to configure all Exalogic Compute Nodes at the same time. At this point in time the scripts with documented within this page are designed from Oracle Enterprise Linux but can be tweaked slightly for a Solaris Exalogic installation. In addition we will focus on the external facing 10Gb network because the the 1Gb is management only and should be on a private network whilst the internal InfiniBand network will not be directly accessible to the outside world.

Implementing XML Object Model based on XAM/XDM

Overview

As part of the the migration process for the NetBeans Coherence Module I have decided to migrate my Java/XML implementation from JAXB to a XAM/XDM based model because it will be a more appropriate fit for the advanced XML editor functionality and will remove some of the synchronisation issues seen in my initial release of the NetBeans Coherence Plug-in . As part of this development process I decided that it would be good to put together a simple tutorial that will allow others to repeat the process and cement the development strategy within my own mind.

At present their is currently no automated method of generating XAM/XDM Java Interfaces / Implementation classes similar to that provided by JAXB (maybe a future project if I get time) so I will be documenting my approach to the development process. The NetBeans Coherence module provides editors for the three core Coherence XML files "POF Config", Cache Config" and "Coherence Operational" and for this tutorial I will be working with the pof-config XML file. With Coherence 3.7 the Coherence team has provided XSD definitions of the XML files and hence I will be working with these as the source for my implementation.

A future Blog entry will explain how I link the XAM/XDM Model describe here to the existing Advanced POF Editors within the Coherence Netbeans Module.

Netbeans Coherence Project

For those that have been following my "Netbeans Coherence Code Generator Plugin" blog entries you maybe interested to know that we are looking to build this into a future release of Netbeans as one of the core Netbeans Modules. As such I do not plan on putting any additional effort into updating and extending the current Coherence Plugin.

As the development progresses I will keep everyone up-to-date via this blog and the Coherence page on the NetBeans community Wiki.
