A killer non-cost feature was released with the Oracle Database 11g Release 2: Edition-Based Redefinition(EBR).
EBR makes it possible to work with different editions of a database object. This means that we can have different versions of an application that connects to different editions of the objects in the same schema. Using EBR also gives the ability to perform an online application upgrade of your application an reduce the downtime.
On the 1st of the December, SWEOUG has the privilege to be hosted by Bryn Llewellyn from Oracle.
What you can expect:
You will appreciate the conceptual and practical challenges that any technology that aims to support zero-downtime application patching must meet. You will understand how EBR meets these challenges. And you will realize that no other conceivable approach could meet these. You will gain a deep understanding of EBR’s key features: the edition, the editioning view, and the cross edition trigger. The workshop will prioritize giving you a robust mental model so that you will be able confidently to design how you will adopt EBR in your database and then implement EBR exercises to meet your zero-downtime patching requirements. You will be shown the SQL statements and PL/SQL subprogram calls that you need in sufficient detail to make your new understanding concrete and immediately usable.
Bryn Llewellyn Distinguished Product Manager Database Server Technologies, Oracle HQ
Bryn Llewellyn has worked in the software field for more than thirty-five years. He joined Oracle UK in 1990 at the European Development Center to work on the Oracle Designer team. He transferred to the Oracle Text team and then into consulting as the text specialist for Europe. He relocated to Redwood Shores in 1996 to join the Oracle Text Technical Marketing Group. He has been the product manager for PL/SQL since 2001. In 2005, he became responsible, additionally, for edition-based redefinition (EBR for short). This is the Oracle Database capability that supports online application upgrade. It’s hard for Bryn to remember his life before Oracle. He started off doing image analysis and pattern recognition at Oxford University (programming in FORTRAN) and then worked in Oslo, first at the Norwegian Computing Center and then in a startup. In Norway, Bryn programmed in Simula (its inventors were his close colleagues). This language is recognized as the first object-oriented programming language and was the inspiration for Smalltalk and C++.
