Oracle Database Performance

Oracle Database performance, made visible

Find what is consuming your database — and what to do about it

Slow SQL, plan regressions, excessive execution rates, blocking sessions and unexpected workload changes are difficult to solve without historical evidence.

OneClickDBA combines Harry — Performance Scraper for Oracle Database with senior DBA expertise to collect the right performance data, expose it through clear Grafana dashboards and turn it into prioritized, actionable findings.

Collect once. Investigate from anywhere.

Oracle Performance Visibility Pack

A fixed-scope deployment that gives your team long-term visibility into Oracle Database workload and performance without having to design and assemble the complete platform.

What you get

• Harry installation and configuration
• Deployment using Linux services, containers, Docker Compose or Kubernetes
• PostgreSQL performance repository
• Grafana dashboards and datasource configuration
• Connection of the agreed Oracle databases
• Retention and partitioning configuration
• Collection interval and overhead review
• SQL statistics, execution plans, waits, sessions and blocking visibility
• Initial review of top SQL and resource consumers
• Deployment documentation, configuration backup and handover session

Harry’s core collection is designed to operate without Oracle Diagnostics Pack. Collectors requiring separately licensed Oracle features are disabled by default and are only enabled when explicitly agreed.

Proof of Concept

€1,500–€2,500

For a first technical evaluation:

• One Oracle database
• One Harry deployment
• Existing or bundled PostgreSQL and Grafana
• Basic retention configuration
• Initial validation
• Concise findings report

Standard

€3,500–€5,000

For a small production environment:

• Multiple Oracle databases
• Production-ready deployment
• Retention and partitioning design
• Dashboard customization
• Initial performance review
• Documentation and knowledge transfer

Enterprise

From €6,000

For RAC, multiple environments or larger estates. The proposal is adapted to the database topology, deployment model, security requirements, integrations and retention volume.

Oracle Performance Assessment

A focused performance investigation based on real workload data collected over 7 to 14 days.

This service is designed for organizations experiencing slowdowns, instability or unexplained resource consumption but lacking the historical evidence needed to isolate the causes.

What we investigate

• Top SQL by elapsed time, CPU, logical reads and physical reads
• High-frequency SQL whose total impact is easy to miss
• Expensive executions and excessive buffer gets
• Execution plan changes and possible regressions
• Full scans and temporary-space-intensive operations
• Repeated blocking and concurrency patterns
• Parsing, cursor churn and potential bind-variable issues
• Suspicious cardinality estimates and tuning candidates

What you receive

• Technical findings report
• Prioritized list of performance opportunities
• Supporting SQL and execution-plan evidence
• Recommended next actions
• Review meeting with a senior Oracle DBA
• Optional proposal for deeper tuning or implementation

€2,500–€3,500

Larger estates and extended investigations are quoted separately.

Continuous Performance Review

Regular expert analysis for teams that want to detect regressions and optimization opportunities without purchasing 24×7 support.

Each review can include:

• Highest-impact SQL and new resource consumers
• Comparison with previous periods
• Execution plan changes
• Workload growth and execution-frequency anomalies
• Buffer gets, I/O and blocking trends
• Prioritized recommendations
• Written monthly report
• Technical review meeting

Basic

€300–€500/month

For one small Oracle environment, with a monthly review, concise findings report and review call.

Professional

€750–€1,200/month

For multiple databases, deeper SQL and plan analysis, historical comparison and a prioritized optimization backlog.

Custom plans are available for larger Oracle estates or more frequent reviews.

Why OneClickDBA and Harry?

• Historical evidence: investigate what happened before the user called, not only what is happening now.
• Fast correlation: move from workload changes to the SQL statements and plans responsible.
• Independent data: retain your performance history in PostgreSQL and explore it through Grafana.
• Low-friction access: give DBAs and technical teams useful visibility without working directly on production for every investigation.
• Senior DBA interpretation: receive prioritized findings rather than another dashboard full of unexplained metrics.
• Open-source foundation: Harry is open source, transparent and deployable in your own infrastructure.

Harry is a decision-support platform. Recommendations are reviewed against the customer’s workload, architecture and operational constraints before implementation.

Service boundaries

These services focus on performance visibility, analysis and optimization. They do not include:

• 24×7 support or on-call incident response
• Availability SLAs
• General database administration outsourcing
• Emergency troubleshooting

Urgent investigations, implementation work and custom integrations can be scoped separately.

Start with real workload data

Whether you need visibility, a focused assessment or continuous expert review, the first step is a short conversation about your Oracle environment and the result you need.

Tell us how many databases you operate, whether RAC is involved and what performance problem you want to solve.
