Crawl … Walk … Run … Fly In-place patching via EM12c Some provisioning of Database homes Some provisioning of Cluster Ready Services (CRS) Out of place patching of database homes Gold Copies for each unique configuration Leveraging templates and profiles All provisioning via EM12c Patch frequency increased to semiannual or quarterly Utilizing Change Activity Planner Cloud Provisioning

  24. EM12c Provisioning – Lessons Learned - Success • Test EM12cpatches/upgrades • Oracle Home and inventory verification (especially for Veritas) • Sticking with Oracle (RAC) vs other Clustering (Veritas) • Having a dedicated EM12c team (we have 2 people) • Global Credentials • Maintain currency with EM12c and database codebase • Extensive testing of provisioning and patching

  25. EM12c Provisioning – Lessons Learned - Challenges • Initial /tmp space too small • Assign to single person • Tried to implement prior to proper training • Entrenched DBA team with decades of experience • New approach to one-off patches • “Configuration Pollution”

  26. EM12c Provisioning – Future • Leverage Patch templates more • Leverage Provisioning Profiles more and better • Integrate • Patch Levels • Gold Copies • Patch templates • Change Activity Planner • Attempt the 100% provisioning goal • Accelerate the patching cycle • Develop Cloud Proof of Concept
