Services
I am your reliable partner for mission critical issues or “must not fail” projects and always up to go the extra mile with you. I keep the focus on your needs and issues without wasting time by playing political games. This level of expertise has never been so affordable, so flexible or so easy to acquire. All services are provided under confidentiality agreements.
Oracle Database & Application Performance
All of my performance services are based on a systematic and scientific performance analysis approach called "Method-R" - an end user response time based performance improvement method that yields maximum economic value to your business and enables reliable performance forecasts.
Based on this method my advanced Oracle performance tuning service consists of top-notch database, application (PL/SQL or client-side code) and SQL statement analysis including cost based optimizer (CBO) troubleshooting, logical and physical data model design, application instrumentation, benchmarking of scalability and optimizing operating system (primarily AIX, Linux and Solaris) configuration for Oracle database systems. Based on my long-time experience with SAP on Oracle I provide specialized Oracle database services for SAP like performance analysis and tuning of SAP systems, SAP applications and R3load based migrations.
I also conduct client-specific performance tuning workshops or public online trainings.

Oracle Database Internals & Operating System Troubleshooting
My troubleshooting services tend to analyze, fix or at least provide a work-around for Oracle RDBMS core problems or operating system (primarily AIX, Linux and Solaris) integration issues.
Since years I spend a lot of time researching and debugging the Oracle RDBMS core with eBPF, GDB, DTrace or SystemTap and you can easily benefit from this rare internals knowledge in business critical situations like shared pool issues, sporadic memory leaks, general memory issues, unexpected ORA errors, unpredictable I/O behavior, database crashes with core dump, a stuck database and many more.
I help you to understand the corresponding Oracle core component, isolate the root cause, create an isolated and reproducible test case (for Oracle support if needed) or research your specific issue from the scratch.

About Me & Company
Biography
My name is Stefan Koehler and I am an independent Oracle database consultant and the founder of Soocs.I started my career with an "IT specialist / system integration" apprenticeship in 2001 and completed successfully 3 years later as one of the best in my year. Afterwards I worked as a classic *nix admin (primarily focusing on IBM AIX and Linux) and Oracle DBA for round about 2 years before I joined the SAP area with the main focus on Oracle databases and SAP performance tuning. In 2011 I founded my own company Soocs to provide independent and specialized consulting services for Oracle database performance tuning and internals troubleshooting in mission critical environments.
Since more than 21 years I follow my passion about Oracle and specialized in Oracle performance tuning and troubleshooting, especially in Oracle cost based optimizer (CBO) and database internal related topics. I am not just interested into understanding how an Oracle database feature works, but also how it is implemented in detail. In consequence I research a lot of Oracle database internals for education purpose or on client’s needs. In addition Oracle High Availability and Oracle Backup and Recovery are completing my skill set.
Nowadays I primarily work as an independent Oracle database performance consultant and researcher in large mission critical environments (e.g. +10 TB databases, +4000 concurrent users, etc.) for market-leading companies or multi-billion dollar enterprises in various industries all over the world. I usually support my clients in understanding / solving complex Oracle performance issues and troubleshooting nontrivial database issues on very short-term contracting basis.
I constantly share my experiences, findings and knowledge with the Oracle and SAP community through my blog and my activity on Oracle-L, Oracle technology network, SAP community network and Twitter. Sharing knowledge is one of my key aspects when working with clients or interacting with the community. I am also one of the leading contributors on the SAP community network in the "SAP on Oracle" area and I received awards by SAP for being the #1 SCN Topic Leader (2012/2013) – SAP on Oracle and #2 SCN Topic Leader (2013/2014) – SAP on Oracle.
In 2015 I received the greatest honor in my professional career as I was invited to join the well-known OakTable network, an informal organization of Oracle experts around the world, who believes in better ways of administering and developing Oracle based systems. I am also recognized and rewarded as an Oracle ACE by Oracle's ACE program.

Stefan's in-depth knowledge of the Oracle database, combined with his ability to delve deep into Linux and storage subsystem configuration has proved invaluable to our company. We particularly appreciate the convenience to being able to collaborate with him via Slack.
Stefan is a brilliant Oracle Consultant who knows not only the Oracle DB, especially the undocumented depths down to individual C-functions, but also the underlying operating systems, in our case IBM AIX. It is especially this combination that makes him so valuable to us and has saved us more than once. You recognize that he spends a lot of time with research and education. He knows every article, every tool and has contact to everyone in the Oracle community who is important.
