Get verified Oracle DBA Expertsready to start in minutes.

Our DBAs start with the data, not guesswork. They pull an AWR (Automatic Workload Repository) report across the problem window, read the top wait events, and use ADDM (Automatic Database Diagnostic Monitor) to surface the highest-impact findings. From there they drill into ASH (Active Session History) to see exactly what sessions were doing during a spike, and use SQL Monitor to capture real-time execution plans for long-running statements. When a query plan flips, they stabilise it with a SQL plan baseline or a SQL profile rather than hinting blindly, check optimizer statistics freshness and histograms, and review the buffer cache and PGA advisories before resizing memory. They also examine segment-level stats for hot blocks and ITL contention. The PM confirms your Oracle version and edition first, since Diagnostics and Tuning Pack licensing affects which tools they can legally use.

Yes. Backup and recovery is core DBA work, and every DBA we place is verified on RMAN. They design incremental backup strategies with block change tracking, configure the Fast Recovery Area, set retention policies, and crucially they test restores rather than assuming backups work. For point-in-time recovery they use RMAN with archived redo logs and flashback technologies (Flashback Database, Flashback Table, Flashback Query) to undo logical errors fast. For high availability they configure Oracle Data Guard with physical or logical standbys, tune the protection mode (Maximum Availability vs Performance), set up Fast-Start Failover with the observer, and validate role transitions. For shared-everything scale-out they deploy and patch Oracle RAC clusters with Grid Infrastructure and ASM. The PM aligns the RTO and RPO targets with your business before any design work begins.

Yes. Real Application Clusters is a specialist area and we vet for it explicitly. Our RAC DBAs install and patch Grid Infrastructure, manage ASM disk groups and rebalancing, configure SCAN listeners and node VIPs, and tune cache fusion interconnect traffic to avoid gc buffer busy and gc cr block wait events that plague poorly designed clusters. They use srvctl and crsctl to manage cluster resources, configure services for workload-based connection routing and Transparent Application Continuity, and apply rolling patches with opatchauto to avoid downtime. They also diagnose node evictions by reading the CRS, CSS, and OS logs together, and tune the OCR and voting disk placement. For migrations they plan single-instance to RAC conversions carefully. The PM confirms your cluster topology, storage, and patch level so the DBA arrives with the right runbook.

A PM is assigned within 10 minutes of booking and scopes your requirement on the first call. For a clearly defined task a performance fire, a failed backup, a blocking lock, a stuck standby a vetted DBA typically starts the same day, often within the hour for a production-down emergency. We offer three engagement models: project-based (a fixed deliverable like a RAC build or a migration, with milestones), dedicated (a DBA embedded with your team for a sprint or longer), and on-call burst capacity (hours drawn down as incidents arise, ideal for covering an on-call gap). You can scale up or down between engagements and cancel after any of them. The PM coordinates the DBA with your infrastructure, network, and application teams so storage, firewall, and listener changes are never a blocker.

Yes. Migration is one of our most common Oracle engagements. Our DBAs plan and execute version upgrades with AutoUpgrade, cross-platform moves with Data Pump (expdp/impdp) and Transportable Tablespaces, and near-zero-downtime migrations using Data Guard or GoldenGate to keep a target in sync while the source stays live, then cut over in a short window. For cloud moves they migrate to Oracle Cloud Infrastructure (OCI) and Autonomous Database, using the Zero Downtime Migration (ZDM) tool, the OCI Database Migration service, and SQL Performance Analyzer to catch plan regressions before go-live. They right-size compute and storage, validate character set conversions, and rebuild jobs, directories, and DB links on the target. The PM scopes your source and target versions, downtime tolerance, and licensing model so the migration plan is realistic and reversible.
