Ivo Dujmovic is an architect in our hard-working Applications Technology Integration team.  We were lucky to get some of his time at OpenWorld 2006 this year, where he discussed the deep innards of the Release 12 technology stack. 

Release 12 Techstack Overview: Overview of three-tier logical architecture for E-Business Suite Release 12, including the database, application server, and desktop tiers. 


For the most comprehensive preview released so far on how the Release 12 technology stack will be architected and work, take a look at his presentation.  He covers:
  • Highlights of new R12 techstack components
  • New Application Server 10g (10.1.2 & 10.1.3) ORACLE_HOMEs replacing the 9iAS 1.0.2.2.2 O_HOMEs from 11i
  • Switch from JServ to Oracle Containers for J2EE (OC4J) for running servlets, Java Server Pages (JSP), and Enterprise Java Beans (EJB)
  • OC4J Deployment details, including replacements for jserv.conf and jserv.properties configuration files
  • New R12 filesystem layout, including the introduction of an Instance Home (INST_TOP)
  • New use of Oracle Process Manager & Notification Server (OPMN)
  • New Forms 10g deployment
  • Comparison of 11i and R12 environment variables
  • Discussion of relative benefits of Forms Servlet vs. Server (socket) mode deployments
  • Disabled mod_plsql in R12 (more about this in a later article)
  • Things you can do today to prepare for R12
