2 and 9 May 2024: Oracle on Power Best Practices

Hello everyone and welcome to the May Power Systems VUG! For our sessions this month we have a special Oracle on Power 2-part series featuring brand new content from our long-time Oracle SME Ralf Schmidt-Dannert.

Oracle Database on AIX - Best Practices (Memory and CPU)

  • Review of key AIX concepts for memory and CPU management and learn how they can impact an Oracle database. 
  • Discuss best practices when deploying Oracle databases on AIX to optimally utilize AIX memory and CPU features. 
  • This session is focused on Oracle 19c with POWER10 based systems and AIX 7.x.

Oracle Database on AIX - Best Practices (IO and Miscellaneous)

  • Review key AIX concepts for IO management and highlight how the selection of specific IO features can impact an Oracle database. This will then lead to a discussion of Best Practices when deploying an Oracle database on AIX to optimally utilize AIX IO features for the Oracle database. 
  • This session will conclude with a review of additional resources, as well as latest available patches, and is focused on Oracle 19c with POWER10 based systems and AIX 7.x.

Ralf Schmidt-Dannert has over 32 years of experience in IT and currently works as a Principal IT Specialist with the IBM Advanced Technology Group, ISV on Power - Oracle at IBM. He has spent most of his career focused on very large database environments, designing, testing, and troubleshooting solutions for high performance, high availability and near zero data loss disaster recovery.

Ralf has helped customers in the financial, telecommunications, utility, retail and manufacturing industries choose appropriate database and infrastructure technologies to meet their business requirements for databases up to a hundred terabytes in size.  Most recently, he has been evaluating and implementing technologies to provide Database as a Service to customers running their databases on IBM Power servers – on-prem or in IBM Power Systems Virtual Server Infrastructure – off-prem.

Please join us for this special two-part series.  As always bring your questions and comments and we look forward to sharing the latest Oracle best practices with you!
