My Technical Pesentations at EMEA OUG Harmony Conference   1 comment

On May 30-June 1st, I was invited to present  at 3rd EMEA OUG Harmony conference. The conference was held on two locations:  at Aulanko, Hameenlinna , Finland on May 30-May31 and Riga , Lativa on June 1st. My presentations at Finland conference were 1) Oracle11g R2 Clusterware: Architecture and Best Practices of Configuration and Troubleshooting; 2) Oracle E-Business Suite: Migration to Oracle VM Template Based Deployment, while my presentation at Lativa conference site was Oracle E-Business Suite: Migration to Oracle VM Template Based Deployment. 

The session “Oracle11g R2 Clusterware: Architecture and Best Practices of Configuration and Troubleshooting” aimed to provide DBAs some practical understanding and best practices of 11g R2 RAC infrastructure that are crucial to the stability and scalability of the RAC database. In this session I started with some technical discussions on the architecture of 11g R2 Clusterware and ASM; then focused on the shared storage and ASM best practices for OCR/voting disks, ACFS and RAC database files. I  spend some time on configuration of SCAN IP, GNS service and the private interconnect. At the end, I  covered some tips and the diagnostic tools for troubleshooting clusterware issues such as node eviction . Presentation slides can be downloaded from here:

The session “Oracle E-Business Suite: Migration to Oracle VM & template based deployment ” discussed the a newly developed method to migrate an existing Oracle E-Business system on physical servers to a virtual environment and also to learn how to create and use the VM templates of customers’ own project specific Oracle E-Business systems for on-going project. The session discussed how to leverage the benefits of Oracle VM such as high availability and scalability and server partitioning for Oracle E-Business suite R12.1 infrastructure. The methods mentioned in this presentation won the 2011 OAUG innovator of the year award.The presentation slides can be downloaded here  for Finland conference and here for Lativa conference.

A great highlight of attending  OUG EMEA Harmony 2012 conferencde  was to meet the legendary relational database researcher and author Chris J Date. I took the photo below while Chirs J Date was giving his keynote presentation “Missing Information”:
