In the blog entry “GlassFish ESB v2.2 Field Notes – Exercising Load Balanced, Highly Available, Horizontally Scalable HL7 v2 Processing Solutions”, at http://blogs.czapski.id.au/?p=13, I present the GlassFish ESB v2.2-based load balanced, highly available, horizontally scalable solution for HL7 v2.x delimited messaging, using both the HL7 Binding Components, Web Services and JMS in request/reply mode. The one and a half hour recording of me discussing and demonstrating this solution is available as a Flash Movie (SWF), “GFESB_LB_HA_Demo_Session SWF ” at http://blogs.czapski.id.au/wp-content/uploads/2010/03/GFESB_LB_HA_Demo_Session_SWF.swf (62.7Mb download)

It seems frequently assumed that architecting and deploying Highly Available (HA) solutions requires Application Server and/or Operating System clustering. When it comes to SOA and Integration solutions this is not necessarily a correct assumption. Load Balanced (LB) and Highly Available HA) SOA and Integration solutions may not require that degree of complexity and sophistication. Testing LB and HA solutions requires infrastructure consisting of multiple hosts and the ability to “crash” hosts at will. With virtualization technologies available now it is far easier to use multiple virtual machines then to use physical machines. It is also easier and potentially less destructive to “crash” virtual machines then it is to do so with physical machines.

This note walks through the process of installing a GlassFish ESB v2.2 runtime on the Base OpenSolaris-based VMware Virtual Appliance, discussed in the Blog Entry “GlassFish ESB v2.x Field Notes – Preparing Basic JeOS Appliance for GlassFish ESB LB and HA Testing” at http://blogs.czapski.id.au/?p=15.

At the end of the Note we will have a GlassFish ESB VMware Appliance with GlassFish ESB Runtime infrastructure, ready to use for GlassFish ESB Load Balancing and High Availability testing, or any other purpose for which a GalssFish ESB runtime appliance might be appropriate.
