Oracle Upgrade Best Practices

Expert Oracle Database Tips by Donald BurlesonDecember 29, 2015

Question: We are planning an Oracle upgrade.  What are the different upgrade requirements and challenges?  What is the best roadmap for an Oracle upgrade?

Answer:  Start with my notes on Oracle migration best practices.   

Also note that each release has its own perils, such as these upgrade gotchas.

Your DBA should know these DBA best practices for Oracle upgrades:   

  • Choose the best target release
  •  Check MOSC for upgrade issues, bugs and patches for the target release
  • Choose the appropriate new features to implement
  • Choose the new initialization parameters
  • Setup the upgraded OS and kernel parameters
  • Understand all deprecated features and workarounds
  • Thoroughly test in a DEV environment using real-world SQL workloads from production
  • Perform a complete stress test
  • Carefully plan the production rollout

You are way better off hiring an expert Oracle migration consultant who has done this many times before since they will know all of the pitfalls and tricks required to be successful.

If you want to get your upgrade done right with minimal downtime and risk, I highly recommend calling 800-766-1884 and hiring a remote upgrade expert!
