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.

Hey, I will set up your new Oracle 19c instances (listener, tablespaces, security hardening) and tune your existing databases using AWR/ASH analysis and indexing strategies to hit measurable performance baselines. On a recent Data Guard environment, reorganizing a stats collection schedule and rewriting three high-cost SQL plans dropped average query response time enough to eliminate the nightly batch backlog entirely. Questions: 1) Are the new 19c builds going on bare metal, OVM, or cloud infrastructure? 2) How many Data Guard standby configurations are active today across your production instances? Share your current AWR snapshot from the busiest instance and I will pinpoint the top wait events before we scope the full engagement. Ready to start whenever you are. Kamran

Hello, I will serve as your Oracle 19c Database Administrator to manage your production databases, handle installations, execute upgrades, and provide twenty-four-seven support. I will configure your fresh Oracle 19c environments, including listeners, custom tablespaces, and security baselines. For performance optimization, I will run and analyze AWR and ASH reports, use the SQL Tuning Advisor, build appropriate indexes, and manage statistics. I will coordinate your patching and upgrade workflows using RMAN for secure backups, establishing verified rollback plans. Furthermore, I will manage your Data Guard physical standby databases for high availability and use Data Pump parameters to handle logical data migrations. I am fully available to participate in your on-call rotation to ensure immediate incident response. 1) Are your Oracle 19c environments hosted on-premise, or are you running them on a cloud platform like AWS or Oracle Cloud Infrastructure? 2) Are you currently running standard Single Instance databases, or do you utilize Oracle Real Application Clusters for your high-availability workloads? 3) What is the typical size of your primary databases, and are there specific transaction bottlenecks you are experiencing currently? Thanks, Bharat

Hi, I can support your Oracle 19c production environment with new database creation, performance tuning, upgrades, patching, Data Guard, RMAN backups, Data Pump migrations, and 24×7 incident response. The best solution is to first review your current Oracle architecture, workload patterns, Data Guard setup, backup policy, patch level, alert logs, and performance baselines. I’ll then handle fresh 19c installation, listener configuration, tablespaces, users, security hardening, monitoring, and full health-check documentation. For tuning, I’ll use AWR/ASH, SQL execution plans, SQL Tuning Advisor, indexing, statistics management, wait-event analysis, and parameter review to improve response times safely. I’m comfortable with Oracle 19c, RMAN, Data Guard, expdp/impdp, PSU/RU patching, SQL tuning, performance baselines, backup validation, rollback planning, and production DBA support. Deliverables will include: * Oracle 19c database creation * Listener and tablespace setup * Security hardening * AWR/ASH performance review * SQL and index tuning * Statistics management * RMAN backup and restore validation * Data Guard support * Data Pump migration support * Patch/upgrade planning and execution * Health-check and change documentation * 24×7 support as required I’ll focus on stability, zero data loss, clean upgrade execution, measurable performance improvement, and clear communication during critical production work.

Your Data Guard setup will fail over incorrectly if you haven't tested switchover procedures under load, and unplanned downtime during a PSU rollout will cost you more than hiring the right DBA upfront. Quick questions - are you running Active Data Guard or standard physical standby, and what's your current RTO target? And have you benchmarked your top 10 SQL statements to confirm indexing won't break existing execution plans? Here is the architectural approach: - ORACLE 19C: Build hardened instances with automated RMAN backup validation, listener security lockdown, and tablespace growth monitoring that prevents midnight disk-full alerts. - PERFORMANCE TUNING: Use AWR baselines and SQL Tuning Advisor to eliminate wait events, then rebuild statistics and indexes without locking production tables during business hours. - DATA GUARD: Architect zero-downtime patching workflows using rolling upgrades across standby nodes, with automated switchover scripts and post-patch alert log parsing. I've managed 24x7 Oracle environments for financial services clients processing 2M transactions daily with sub-200ms query response times. Let's schedule a 20-minute technical call to review your current AWR reports and Data Guard topology before you commit to a support contract.

I can take ownership of this Oracle 19c work as a controlled production engagement, beginning with an evidence-based assessment before any change. Approach: 1. Inventory database count, OS/storage, RU level, backup status, Data Guard topology, RPO/RTO, maintenance windows, and support SLA. 2. Establish a health and security baseline covering listener, tablespaces, users/roles, alert logs, RMAN recoverability, and Data Guard lag/failover readiness. 3. Use AWR/ASH and execution plans to isolate measurable bottlenecks, then tune SQL, indexes, statistics, memory, and I/O with before/after evidence. 4. Prepare patch/upgrade runbooks with pre-checks, validated backups, rollback steps, dry-runs where possible, and post-change verification. 5. Document Data Pump procedures, monitoring thresholds, incident escalation, and operational handover. I bring 14+ years of enterprise software architecture and production-system experience, including large-scale e-commerce evolution and legacy-system stabilization. I work from logs, metrics, and reproducible diagnostics rather than generic changes. The 30-day bid covers assessment, remediation/implementation, validation, and documentation. Before confirming continuous 24x7 coverage, please provide the database and Data Guard counts, OS/platform, current RU, maintenance windows, and response-time SLA. I will not promise zero downtime until topology and failover paths are validated; every change will have a rollback plan.
