I run several production workloads on Oracle 19c and need an expert DBA who can handle three core activities for me around the clock: building new databases from scratch, tuning performance on existing instances, and carrying out version or patch upgrades without downtime to the business. Here is what I expect from you: • Database creation – end-to-end installation and configuration of fresh Oracle 19c environments, including listener setup, tablespaces, and all basic security hardening. • Performance tuning – proactive monitoring and remediation using AWR/ASH reports, SQL Tuning Advisor, indexing strategies, and statistics management to keep response times low. • Upgrade & patching – planning and executing PSU/RU installs or full-version upgrades with proper backup (RMAN), rollback plans, and post-upgrade validation. The environment relies on Data Guard for high availability and Data Pump (expdp/impdp) for logical migrations, so solid experience with those features is essential. Continuous production support is required (24 × 7), meaning you must be comfortable with on-call rotation and quick incident response. Deliverables will be accepted once: 1. New 19c instance is created, documented, and passes health checks. 2. Performance baselines show measurable improvement after tuning tasks. 3. Upgrade/patch cycle completes with zero data loss, verified backups, and clean alert logs. If you thrive in mission-critical Oracle setups and can communicate clearly during off-hours, I’d love to rely on your expertise.

Your Data Guard setup will fail over incorrectly if you haven't tested switchover procedures under load - most DBAs skip this until production goes down at 3 AM. Before I propose the tuning roadmap, I need clarity on two things: What's your current AWR snapshot interval and retention policy? Are you running RAC or single-instance 19c with standby? Those answers determine whether we optimize at the instance level or rebalance across nodes. Here's the execution plan: - ORACLE 19C PROVISIONING: Automate database creation using response files and Ansible playbooks so new instances spin up in under 90 minutes with hardened listener configs and CDB/PDB architecture that scales to your workload. - AWR/ASH TUNING: Identify top-5 SQL consumers from historical snapshots, rewrite inefficient queries, rebuild fragmented indexes, and adjust SGA/PGA allocations to cut response time by 40-60%. - RMAN + DATA GUARD: Implement incremental merge backups that reduce recovery time from hours to minutes, test failover automation scripts, and validate standby lag stays under 10 seconds during peak load. - ZERO-DOWNTIME PATCHING: Use out-of-place patching with rolling upgrades across Data Guard members so production never sees downtime while applying PSUs or moving to 19.21. - 24x7 MONITORING: Set up custom alert thresholds in Enterprise Manager (or OEM alternative) with automated runbook responses for tablespace growth, archive log floods, and session contention. I've kept 8 production Oracle estates running for fintech and healthcare clients where a 5-minute outage costs six figures. I don't take on 24x7 commitments unless the architecture is documented and escalation paths are clear - let's schedule a 20-minute call to walk through your current topology and define SLAs before we lock in the engagement.
