I’m Sagar, a Lead Oracle Database Administrator specializing in Oracle Exadata and the infrastructure around it. I’m an Oracle Certified Professional (OCP).
My day-to-day work covers:
- Multi-node RAC clusters on Exadata
- Data Guard for high availability and disaster recovery
- RMAN backup and recovery strategy
- TDE and wallet management
- ZFS Storage Appliances for backup and replication
- OCI Exadata Cloud@Customer (ExaCC)
I’ve worked on large-scale infrastructure migrations across production datacenters and lead DBA teams through them.
About this site
InfraDBA is where I write up real troubleshooting cases and operational lessons from running Oracle at scale: what broke, how I diagnosed it, and what fixed it. Examples are sanitized, and opinions are my own.
