Senior Oracle Database Administrator specializing in RAC, Data Guard, and AIX-to-Linux migrations for mission-critical systems.
IndiaWhat I'm looking for
I’m a Certified Oracle Database Administrator (OCP 19c) with 7 years of experience managing mission-critical Oracle environments for major financial institutions, including CanaraBank and PNB MetLife.
My work centers on Oracle RAC (12c/19c), high-availability architectures, and disaster recovery using Physical/Active Data Guard—focused on maintaining 24/7 uptime, rapid recovery (RTO), and zero data loss (RPO).
I proactively tune and troubleshoot performance with AWR/ADDM, Explain Plan, SQL Trace, and targeted investigation of blocking sessions and storage bottlenecks. I also drive enterprise patching and stability through quarterly CPU/PSU updates and RAC-aware rollover patching.
Alongside administration, I lead modernization and platform shifts—contributing to AIX-to-Linux migrations, managing ASM/OMF storage evolution, and executing reliable cloning (RAC-to-non-RAC and vice-versa) for testing and development cycles.
