Overall Satisfaction with Oracle Database 12c
We use Oracle 12c across our entire organization on all our SAP applications.
- Upgrade: Oracle 12c allowed us to upgrade 45 databases with no issues from 11.2 to 12.2 using DBUA.
- RAC: We were able to implement two 4 nodes Oracle 12c RACs on linux. The implementation was straight forward and similar to Oracle 11 but with fewer issues.
- Multitenant: Oracle 12c multitenant feature will allow us to run many more databases on the same hardware.
- After upgrading to 12.2 we started receiving many ORA 600s. The fix was required us to reorg the offending table/indexes.
- Stablility: Oracle 12c stability (besides some ORA-600 errrors) has been great. The ORA-600 required us to reorg some tables.
- Easy upgrade: The upgrade process to Oracle 12c using DBUA has worked flawlessly.
- OEM: Integration of our Oracle 12c databases with OEM has been great. No issues or patches needed with OEM 13.2.
- We performed a hardware refresh in conjunction with our Oracle 12c upgrades. We upgraded to Redhat Linux 7, consolidated to less (but more powerful hardware), and upgraded to Oracle 12c. We also moved to new flash storage in the process.
