The hierarchy is divided into at least two levels: level 1 or L1 blocks are stored as a shared data structure and map free space in a tablespace, whereas level 2 or L2 blocks are stored as separate local copies at each database instance and map to the L1 bitmap blocks. The L2 blocks each indicate, for each L1 block of a respective subset of a plurality of L1 blocks, a maximum size of a largest extent that can be allocated."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hierarchical tablespace space management","description":"A method, non-transitory computer readable media, and system for hierarchical organization of tablespace free space metadata in a database are provided.
