HANA prerequisites
- Certified hardware or certified cloud instances (strict CPU-to-memory ratios).
- A certified Linux distribution with HANA-specific OS tuning.
- Correctly sized memory, the dataset must fit in RAM.
- Properly laid-out data, log and shared file systems.
The installation
HANA is installed with its own lifecycle tool (hdblcm), which sets up the HANA instance, system database and (optionally) tenant databases. You define the SID, instance number, and administrative users, and configure memory and persistence. Because HANA is memory-resident, sizing and OS tuning done beforehand are what make or break it.
Key HANA concepts
- System DB vs tenant DBs: HANA supports multitenant databases (MDC).
- In-memory + persistence: data lives in RAM but is persisted to disk (data + log volumes) for durability.
- Column store: the default for analytics-friendly performance.
Verify
After install, confirm HANA starts, you can connect (e.g. via HANA Studio/cockpit), and memory and persistence are configured as intended. HANA problems downstream almost always trace to sizing, OS tuning or file-system issues here.
Common pitfalls
- Insufficient memory for the dataset.
- Uncertified hardware/instances.
- Skipping the HANA-specific OS tuning.
