Self-hosted Oracle moved to Exadata for ServiceNow

Anyone that is self-hosted using Oracle moved to using Exadata on-prem instead of regular database?

Any issues encountered during migration that were not expected?

Have you gotten better performance and more HA than before?

And what level of HA is so?

Yes indeed, we’ve seen a few teams move from a self-hosted Oracle DB on standard hardware to Exadata on-prem and overall the experience has been positive, but not without some lessons learned.

Migration-wise, the database move itself is usually straightforward RMAN, Data Guard, ZDM but what often catches people off guard is the amount of planning and testing needed. Sizing, network setup, and understanding how workloads behave on Exadata (parallelism, Smart Scan, I/O patterns) takes more effort than expected. 

Performance is generally better especially for I/O-heavy, reporting, or mixed workloads. Most teams report more consistent performance under load rather than just raw speed improvements across the board. 

So in a nutshell:

  • Better performance and stability for the right workloads

  • Strong local HA with RAC

  • More operational complexity and higher cost

  • Biggest surprises I seen tend to be around planning, skills, and licensing rather than the migration itself

Hope that helps.
