I’ve heard anecdotal reports suggesting that some customers hold off on upgrading to a given E-Business Suite release until we’ve done so ourselves here at Oracle. Oracle went live on R12.0.3 in January 2008, and a reader reminded me that I haven’t highlighted this adequately. Here’s a critical presentation from Eugene Weinstein and Sharon Leong at OAUG Collaborate 2008 (Denver) that I’ve been remiss in profiling:
Eugene and Sharon cover a lot of ground in this technically-oriented presentation, including:
- A primer on the R12 file system
- Supported upgrade paths from earlier Apps releases (11.5.x, 11.0)
- A detailed step-by-step flowchart of the upgrade process
- Applications DBA (AD) improvements relating to the upgrade process
- Performance improvements relating to the upgrade
- Best practices for:
- Reducing downtime
- Performing pre-upgrade, upgrade, and post-upgrade steps
The Inside Track
Perhaps most significantly, Eugene and Sharon review Oracle’s own Global Single Instance (GSI) experiences in upgrading to Release 12. This discussion includes:
- An overview of Oracle’s production R12 architecture
- A summary of Oracle’s preupgrade statistics (12 Terabytes, 25.8 billion rows of data, and more)
- EBS applications in use at Oracle
- Project planning
- Pre-upgrade planning, the actual upgrade itself, datafile management, and post-upgrade planning
- Keys to success in Oracle’s own upgrade
Eugene and Sharon make a point of emphasizing that their experiences are specific to Oracle’s internal implementation and may not apply to all upgrades. As you’d expect, our internal Applications IT organization has direct access to everyone in Oracle Development. Their notes represent an insider’s glimpse into how an organization with access to the most-skilled EBS talent on the planet performed this upgrade. This is mandatory reading for all Apps architects and DBAs interested in Release 12.
