SAP ASE performes a specific sequence of steps at start-up.
- System databases are recovered on engine 0.
- SAP ASE accepts user connections.
- All engines that are configured to be online during start-up are brought
online.
- User databases are recovered in parallel by a “self-tuned” number of recovery tasks
using the default data cache tuned for optimal recovery performance.
During a fail over in a high availability system, failed over user databases are
recovered and brought online in parallel.
