Oracle Database Administrator at Oracle America, Inc. resolving critical RAC and Grid Infrastructure failures across enterprise production environments.

United States

Message

At Oracle America, Inc., I served as a senior escalation point for Oracle Grid Infrastructure, RAC, and ASM issues in enterprise production environments. I resolved critical clusterware failures during patching, including OLR/OCR restoration and Grid binary relinking.

I also resolved OPatch and opatchauto failures across RAC, Grid Infrastructure, and database homes, minimizing customer downtime during patching. I administered RAC databases and ASM instances, and monitored health with CRSCTL, SRVCTL, AWR, ASH, ADDM, and OEM Cloud Control.

At Infosys Limited, I led Oracle database creation and version upgrades, tuned SQL queries, and implemented Data Guard standby databases. Across my database roles, I’ve worked with Oracle RAC, ASM, RMAN, Linux, AIX, Windows Server, and AWS.
