ABOUT ORASOLU
Oracle Database Engineering.
Built from Experience.
ORASOLU is a technical platform focused on Oracle Database engineering, performance, high availability, migrations, infrastructure and automation – built from hands-on experience across enterprise technology environments.
THE PERSON BEHIND ORASOLU
Achitha Rathnayake
Oracle Database Professional · Technology Practitioner
An IT professional with more than 13 years of experience across enterprise technology environments, with Oracle Database as a major area of expertise.
My work spans database architecture, performance, high availability, migrations, modernization, infrastructure, cloud and automation, alongside technologies such as PostgreSQL, MongoDB and Linux.
ORASOLU is where I document that experience – technical investigations, solutions, scripts, tools, experiments and lessons from real technology work.
PROFESSIONAL SCOPE
Where the engineering work happens.
ORASOLU brings together the technologies and disciplines that surround modern database operations – from core Oracle engineering to infrastructure, automation, migration and reliability.
Performance Engineering
Database performance analysis, SQL tuning, workload diagnostics and troubleshooting across complex enterprise environments.
High Availability & Recovery
High availability, disaster recovery, backup and recovery engineering for resilient database operations and business continuity.
Migration & Modernization
Database migrations, platform transitions and modernization initiatives across on-premises, cloud and enterprise environments.
Cloud & Infrastructure
Cloud platforms, Linux environments and database infrastructure supporting enterprise workloads and modern database operations.
Automation & DevOps
Automation, scripting and delivery practices that improve consistency, repeatability and operational efficiency across database and infrastructure environments.
WHY ORASOLU
Built from real technology work.
Database problems rarely exist in isolation. Performance depends on workload and infrastructure. High availability depends on architecture and operations. Migrations depend on both technology and execution.
ORASOLU documents that engineering context through articles, scripts, diagnostics, tools, experiments and technical notes.
The goal is not simply to collect information. It is to turn experience into knowledge that can be understood, reused and applied.
