Defining transaction durability level
The transaction durability level is set with the Logging.DurabilityLevel parameter. The parameter has three different values: relaxed (1), adaptive (2), and strict (3) durability.
Adaptive durability is used only with HotStandby. Adaptive durability means:
If Primary and Secondary are connected and operating normally (in PRIMARY ACTIVE and SECONDARY ACTIVE states), the server uses relaxed durability.
In all other situations (for example, PRIMARY ALONE, STANDALONE), the server uses strict durability.
For an explanation of the differences between strict and relaxed durability, or for more information about the Logging.DurabilityLevel parameter, see solidDB® Administrator Guide.
